#1 harley oil pump how it works wet sumping oil carrier over panhead shovelhead evo by tatro machine
test #2 tatro machine live video feed is coming if i can make it work harley education help needed
the next three videos is just a sample of what can happen live if you don't watch out. you never know where things go after you get going.
i need some help on making this all work because i have the need to do this but no idea how to do it. if you have any ideas on how to help or on the direction you think i should go please contact me at tatromachine@cox.net. if you want to donate some money to make this happen my paypal account is also tatromachine@cox.net.
what format would you like to see?
what time frame would you like me to do this live feed and how often?
should i have a live viewer too or just answer sent questions?
this is just for harley related stuff so lets not get to far off track.
thanks for your help, tatro

This is educational as well as hilarious! The sarcasm is thick! Love it!
Great lesson. Yes, need to watch many several times but the general just how a pump works and sumps come through for those like me- clueless. Thanks again for another densely packed informative vid.
Tatro, I could listen to your knowledge all day long☆☆☆☆☆☆
exactly the kind of topic that would go good on your “live” series. I think I remember you doing a video a few years ago dedicated to the differences between the various oil pump (years and manufacturers).
yes i did and he watched them too. now i have a playlist for them.
tatro
Thank you for all you share Tatro, The knowledge your willing and taking your time to share with others and myself is a tremendous help!
Enjoy every video Tatro, keep up the good work, been working on these things for a long time also but still enjoy watching the interaction with all the characters that come thru your shop.
You just described what my '76 FLH is doing... leaking oil all over the place because the vent tube hole is plugged off!!!!
unplug it and put 10 miles on it and see what happens. it might clear up if the rings are seated. if not, ride it hard for another 10 miles and see if the rings reseat. if that doesn't do it than its time for a topend job.
oh, make sure you have straight 50w or 60w oil in it.
tatro
@@TatroMachine Thanx Tatro, I was already preparing to do a top end job thinking that the gaskets were messed up or missing, as when I run the bike it runs great but leaks oil from every gasket like Jug bases, cam cover and oil pump body base...
The first time I had blowby was when I put a Delorto pumper carb on my Shovelhead. A old, old Harley mechanic told me no problem. Awesome video .
You are very patient👍
Here's a serious offer Tatro! I didn't know you were in SD. I live in Idaho but I'm a 4th generation SD Native. I love riding and wrenching on old iron and plan on coming back to San Diego for the cold winter months. If you could use a good. AND CHEAP part time helper at your shop I would like to apply. I am pretty good with a wrench, will do any shop chores or tasks, machining, clean up, counter help, organize and inventory parts. I don't care as long as I can learn some along the way. I have done hundreds of top ends, carbs, brakes, and resurrected some pretty far gone old Harleys, but there is still a lot to learn. I would like to learn to build motors, from the bottom up etc. and can't think of a better way to learn or really anyone better to learn from. I am disabled with a bad back but can keep a fairly reasonable pace and have my own insurance. I will be looking for something to keep me busy this winter and If you like I will come to work for you. from November 1st 2020, thru May 1, 2020. I can work around 20 hours a week, and I will work for $8 bucks an hour, I figure that's a steal for what I could learn, additionally, if you will give me some training and allow me to "tag along" and help from time to time when you are building motors. I would do that on my own time just for the schooling. There aren't too many mechanics that know these machines like you do, maybe you could use the help? Anyway, I will come and introduce myself when I get to town, if nothing else I am sure I will need parts for one of my bikes. Thanks for the great videos, my 84 will be fixed today cause of this one !
Dang good info.
I have Breather heads and my STD cases have a breather port ( plugged).
I'm going to make it a bottom breather after seeing this 👍
use them both.
tatro
@@TatroMachine Yes Sir planning on it . Thanks.
And I enjoyed your show completely very educational
like to see a video of check valve lapping , and oil pump installation
you can use a push rod to lap the check valve
Very Informative. Thank you. Great learn ing channel. And good old plane English!!!!
Very good information!! Keep it up brother
GREAT INFO!!!!!
Thank you! Very through response! And thanks for your videos!
you could always add it to the post.
tatro
Thanks I’ve been wanting to know what’s going on in my shovels oil system to make it puke oil after it’s been sitting.
You are very intelligent and very patient with that dumb ass guy. I loved your dry humor and sarcasm. This is exactly how I teach my new guys on my crew.
Tatro ….. the fucking guy has forgot more than most of us will ever remember! Would love to meet you and shake your hand !
Can people send you stuff to work on? There’s nobody like you where I live man!
There's few like him anywhere
We would love to see Tatro Live! Do it 👊💨 and thanks for sharing 🏍️💨
Great info, Thanks!
Wood take care oil over fil by draining oil out motor when sit long time ansee fix check when you refill oiltankwith oil you take out
Your partner has no idea thought a Sportster was a cvo he just listened I like that I guess all new engines are junk according to you
He's clowning
I wanna learn everything there is to know about bikes, but I'm not sure what to start reading up on.
2 Winters ago I tore down my Shovelhead to the frame and put it back together in a couple days.
The problem with wet sumping is there isn't a seal in the case for the shaft, machine out the case for a seal and wet sumping is over. Tom pump pro
what a load of crap. they already have one. what a dumbass.
tatro
on a 1996 EVO engine on which side the seal lip should be positioned, there seems to be confusion about the correct way to install it, nobody explains or shows on video the correct installation position, I think the attached to prevent the high pressure oil from going into the return gear side of the pump, sorry for the translation I speak french, thank you
i say every time i do a motor how stupid harley does things when they seem to have no common since. you got it right on the seal installation and why.
tatro
Hello, I am rebuilding a 72 and wondering about your comment , one year only pos. Can you tell me more about the 72 pump? Thanks
yes, its the last year of that design. 1968-72. the next design is 1973-74 and then 1975-80. the 1981-91 is called the evo pump and the late evo pump is the 1992-99.
the 1968-72 pumps basically had one oil hole feeding the complete motor so the crank takes all the oil and leaves very little for the topend. in 1973 harley changed things by splitting the flow between the top and bottom ends. the bottom end now has a pressure check valve added between the top and lower end. once the oil pressure is built up feeding the topend, the check valve opens up and feeds the lowerend. after that the extra oil is blown out another hole into the cam chest. in 1975 harley changed some stuff in the oil pump body and change the drive gears to turn the oil pump faster. this is what makes the big difference in oil pump flow and pressure.
s&s has good instructions on how to change some of the oil holes in the motor case when you install the later 1981-91 evo style oil pump on your motor.
tatro
Yes!...Yes!...Brilliant!
Is there anyway to recondition the pump body that is scored in the scavenger side of the body
yes, brazing and remachining on a cast iron pump and tig welding and remachining on the alum ones.
tatro
what might be the problem where the oild continuously pumps out blowout but will empty oil tank if u let it?
Hey Tatro, would you use the reedvalve breather in an early Evo motor? S&S says they are only for use in the later top breather evos, but i been told from several people that they work fine in the older evo motors.
i am 50 50 on them now. i have used lots of them on all years. some use oil and most work good.
tatro
@@TatroMachine ok thanks for the reply and thanks for making great informative videos.
✌
It has been a good vid I still won’t to know if I can just Block off the pipes going to my chain case 1981 FLT has some one got a answer for me and the best way or could I join the pipes ?
sure you are!
I was told if there’s no oil under it then there’s no oil in it
Hello, good clip After filling in the new oil, I filled too much, oil started to come out of the air filter, and even after I drained some of the oil, oil still flows and empties my oil tank. What is the cause and what is the solution? Thanks, I have FXEF fat bob model 1985 evo engine filter s&s
go ride the bike for 10 miles and let things get back to normal. just make sure you have atleast 1/2 a tank of oil before you go.
tatro
@@TatroMachine but all riding time oil continue dripping from vent its danger
Fkvjv
have you riden the bike yet? until you run the motor long enough to equalise the system it will keep dripping. you can take the breather line off and clean all the crap out of it too. its going to drip until it cleans itself out.
you said you just changed the oil so that is what i am going off of. if you over heated the mnotor the rings will stop working and have lots of blowby. this will cause lots of oil leaking out the breather and other places. you can check for this by doing a leak down test on your motor. the leak down testing tools don't cost that much anymore.
tatro
Hey Tatro, I'm rebuilding a 74 ironhead motor and I can feel a bit of drag at one point when I spin the breather valve gear of the oil pump by hand, but It spins perfectly when I do it moving the crankshaft with the rods like you do. Do you think it's okay? Thank you
I installed a S&S twin cam dx engine to the Dyna, the engine oil spilled out, the S&S twin cam dx breathing hose would like you to advise me on what happened, what was wrong and what should I do to fix it? Thanks.
Have a qwestion what is your thoughts on the oil pressure spring stretch trick peaple are talking about? I've seen people doing it on you tube and it appears to improve the oil pressure alot but would that actually be bad for the 80cc involving this oil supping problem?
I'm new on the evolution motor and realy enjoy your teachings.
Thank you.
it helps but don't get to carried away with it. tap on the ball a little after you cleaned thing up helps.
tatro
How about a new inline check valve?
Do you recommend using the reed valve style breather on stock Knucklehead motors? Thanks for all the videos
not sure, i have not used one on a stock motor yet. it worked great on a race motor i did for a racer friend.
tatro
@@TatroMachine thank you
Can I use an S &s breather reed valve in a 1954 bottom with a 1970 shovel pump ??.I understand S&s only advertises the reed for later years...Thanks in advance,Joe
Soooo what about the budding riding behind you and your plumbed oil slick? I have an 79 FLH. This sucks
Hey man , i made a catch Container that my breather hose runs into with some oil absorbent cloth inside. Just clean it out every so often.
Drill vent holes on top of container.
Ah hahahah oh shit that was good thanks Tatro!!!
I own a 73 Harley-Davidson FLH Electra Glide I have built it I thought it a basket case I have a question my oil pump has two Ball Bearing in the top of it they told me to change the ball bearing with a pistol but the Piston won't fit in the hole what do I do
ream, hone or lap the hole to get the piston to fit correctly. i don't think the oil pump will work correctly with the ball as a check valve.
tatro
Heck yea 🖖🏽
Just a question on the breather valve I remember their plastic is it better to replace it with a steel breather valve my bike only has about 16,000 miles on it it’s a 98 Fatboy I don’t know if it has the plastic or the steel how do you remember I had a shovel head 75 and I think I replaced it with steel years ago I don’t remember the reason or somebody told me to do it do you think it’s needed or is plastic good enough thank you
the plastic ones are junk. use a s&s reed valve or the earlier steel one.
tatro
Tatro Machine thank you 🖖🏽
which reed valve works the best ie worth the money as they are quite a lot more than OEM
s&s
@@TatroMachine I don't see one listed for Pans from SS....do you buy the shovel and perform a mod to fit in pan?
You could probably hold up a bank with that oil pump housing at 1:45 :)
oil came out from crank case vent
Question, very likely that only you can actually answer: (and, thanks in advance)
I have a sifton 12-9969 oil pump on a 56 pan. Was put on 20 years ago by a good shop (reminds me of your brilliantly sarcastic ass!) and has been a champ always, no issues. The bike went down a decade ago (thank you life, may I have another) and I’ve finally brought it up. As of now my only remaining issue is the chain oiler screw in the pump, as in, I don’t have one. As you know, without it or it misadjusted it’ll drain your oil tank toot sweet and toast your motor.
I ordered one mail order, it’s too fat for the pump. God forbid there be standardization... anyway, do you know if this sifton model is generic enough in its use of this needle screw, or is it entirely sifton/model specific? I’m tempted to take a plain Allen headed screw to the belt sander and cone the end, but I’d much rather have guidance from one of the last remaining actually knowledgeable people left on the planet.
those were just import pumps, sifton never made those non-valvetrain parts they sold at the end. i would just take a screw and cut or grind a tapper onto it.
tatro
@@TatroMachine made a new adjustment screw, I can stop the flow entirely (needle seats completely) into the passage that goes up into the plunger tube. Do you know what other ports are fed /functions shared by that feed route? Is the breather tube /chain mister the end of that line?
The cool compatible screw I found in a junk drawer that already has a beveled tip and seats nicely in the port isn’t a full cone shaped piece, it’s stepped after its nose, then back to threaded shaft (all 10-32 of it) so I need to know if I need to erase a couple of threads immediately prior to the tip to facilitate full oil flow laterally past it (to the breather?)
Dude I need serious help could you please help me I have a 1998 Harley Davidson Dyna wide glide built into a chopper so it's not in the original frame anymore but I had oil and heavy smoke coming out of the exhaust I take it for a ride and all of a sudden the oil cap blows off hits me in the leg and then the bike sounds like it has a lot of friction and wont start like there's no oil in the case anymore please tell me what's wrong so I know what to fix. And just prior to this while all the trouble was happening I don't know which hose it is what it's called but it's the one in the middle and it goes up to the top of oil pump by the tappet filter, it never had any oil in it ever it was always clear
you killed the motor from lack of oil or over heated. the pistons are seized for sure. pull it apart and see how bad everything is and start rebuilding or get another motor.
tatro
How much would you sell a oil pump housing for a 72 Ironhead?
Tatro, I have learned a lot about bottom ends from you and really appreciate it, but George The Animal Steel is annoying as hell.
Do you have a complete Harley 80in evo motor forsale?
This is a good reason to own a Honda. Rediculas oil spewing🙄
Because if a shitty ball bearing that's leaking oil into the base
Who is the big guy at the very beginning? I figure he's a Tatro relative or someone.
But, you seem very used to him. Sometimes, I'm thinking "the poor guy". Other times, l'm like "wtf?". Anyway Tatro, about your hand. You have to be careful of the machine tools. Please, Please Please, take care around the power machines. . . .
But, I like the big guy. I think you should have him on EVERY episode, helping you with this or that.
Wow it would have been really tough to did some of those junk parts out before you started rambling on
Hey boss, I got a question, I bought a bike with a 131 merch performance motor on it. I put it in the shop got it back and now it's sumping bad. I can run it and when I turn it off it dumps half a quart of oil everytime I shut it off. Even if I only shut her down for 15 min. She's a leaky bitch, but how do I fix it? Is it as simple as a check valve ball or do you think I need a new oil pump? It's a performance machine oil pump.
do a leak down test on your motor and see how bad your ring seal is. over 10% will sump, over 20% will dump oil like yours.
tatro
It took The Motor Company until 1993 to figure out how to eliminate the wet sumping problem by relocating the oil bag under the transmission. What I find HILARIOUS is that prior to that they directed the oil line BACK INTO the carburetor via the air box! WTF???? Couldn't they figure out how to get that oil back into the oil bag? Such a dumb ass group of Engineers...
thats harley for you.
tatro
Kenneth Wise ? The oil return did not go into the air filter, that is a crankcase vent line mandated by the EPA to prevent oil from dripping onto the road.
Not all models have the oil bag mounted low. How can these videos be of any interest to you when you don't have a clue ?
@@kurtfoulke5130 Thanks dumb ass however I'm not "clueless" as you say and have been doing this for SEVERAL years now. Any idiot knows the oil return doesn't get fed back to the carburetor. ONLY crankcase ventilation gets fed back through the airbox, and thats what I was referring to. How many times have you had to disconnect that crankcase ventilation line to the airbox after your bike has sat for a month? I know for me its a ritual...
@@kennethwise7108 There is the answer to your problem. Ride More - Cry Less !
😂😂🤣🤣👍
I need one for a 72 Iron Head
