Shortly after I bought my 1st Harley, a 2002 Road King w/35,000 mi. I learned about the nylon shoes breaking. I pulled it apart and found it had better cams put in and also a chunk had broke off the inner shoe so I caught it in time. I put a Screaming Eagle Cam Plate in and new case bearings. Glad you covered just the pump and always wondered why is there no screen as most engines have to prevent any chunks entering the pump? Seems there is room to have a screen on intake to prevent blowing an engine from a siezed pump. Excellent video, Thanks.
Yes I did get lucky. My first Harley and learned about those cam chain shoes on Y.T..... Before teardown I asked meticlous previous owner and he knew nothing about it. He said it runs great, not making any noise so he wouldn't worry about it. One chunk from the inside shoe, with no missing fragments. Still, why is there no inlet screen? Is there aftermarket screens? Beautiful bike but now it needs swing arm bushings as wheel is about 3/4 " to the belt side. Didn't notice when I bought it. Maybe you can do a video changing your bushings.
The reason there's no screen on the scavenger side of the oil pump is the internal pump design has a problem with scavenger side of the pump. A screen would only make it worse. What Harley has done to compensate for no screen on the left inner case there is a deep well that collects any foreign debris. It works well, but when you get to much debris some will run thru the pump. That's when it tears up the motor. The engine itself does have a small cone screen between the pump and the case, but it's very small and if it gets clogged will starve the engine of oil, this cause damage to the engine. Personally I don't like the internal pump. I like the old style external pump which worked extremely well from 1937 till 1999. If I get a swing arm that needs bushings I will definitely video it. Thanks for the input and thanks for watching.
@@tinkeringwithharleys That makes sense. I have noticed that webbing in castings can easily hold foreign materal from moving once it's captured as long as you don't turn engines and gear cases upside down. Thanks for your time.
Just reached 110k on my 04 Electra glide and the pump crapped out on me 😭. Thankfully it lugged itself the half mile home and there were quite a few bits and chunks of metal in there. Hoping Harley has an oil pump so I can get one in there today or tomorrow and get back to riding!
Thanks for the comment, hopefully all's you need is a oil pump, but if you found a lot of metal in the pump I would take a good look at the rest of the motor to make sure it didn't get into anything else. Thanks for watching and ride safe
@@tinkeringwithharleys it wasn’t in the pump just when I took the cover off and you see the plate. It was metal flakes and some larger chunks at the bottom of the inner case. Not too strong with the terminology haha. But where all the oil collects at the bottom is where they were. I’m hoping it was just the busted gear teeth or something. But it made it 110k miles so I’m guessing it just gave up eventually. Harley doesn’t even make the oil pumps anymore, they ruled them “obsolete” apparently haha. Thanks for the reply man! Hopefully getting a new high flow oil pump with a cam plate soon.
@@boxchevyrider88 I’m not sure where I was in the process of my bike when I posted this, but my original engine did blow at 110k. The cam bearing blew out it’s hole and threw metal everywhere. So make sure to take it all apart to make sure it’s just the pump. The new engine I got, another tc88 was from an 02 dyna, threw that in and got about a thousand miles out of it until the pump in that one took a crap. Thankfully didn’t send metal anywhere, stayed together just broke the gears inside itself. My pressure relief valve was also stuck on the cam plate as well. Went ahead and got the whole cam plate, pump and hydraulic tensioner upgrade. Didn’t wanna deal with it anymore haha. The engine supposedly only had around 9k miles on it, got about 11 or so now. Everything seems to be running good! Best of luck to ya man! If your pumps out I’d just go ahead and save and get that whole upgrade for it if it doesn’t have it already.
Hey Tinker, great video. What's your take on the Daytona pumps for the tc88 with stock camplate? I installed one and get 55 psi at highway speed. Is that too much pressure?
Glad you liked the video. I've heard of Daytona Oil Pumps but have never installed one. But everything I've heard about them is good. 55 psi is to high, it should be 36 to 40 psi. I won't put a high volume pump on a stock cast cam plate anymore, due to cam plate failures or pressure relief valve problems. Thanks for the question and thanks for watching. Ride safe.
I’ve done one upgrade with the screaming eagle billet stuff, seems ok. Playing with another bike 01 ultra but just gonna replace the shoes. Thinking about upgrading just the oil pump. Would you recommend changing the spring in the cam plate. At idle the oil pressure gets pretty low although common I don’t like it.
Thanks for the question. If you're going to upgrade to a high flow oil pump I would definitely recommend you change the cam plate. Reason being sometimes the stock cast cam plate has trouble handling the increased oil pressure. Sometimes it works but most times it doesn't. Thanks for watching and ride safe.
Hey Tinker; I have an early 99 Road King and not long after I bought it Harley came out with an upgraded oil pump (1999 1/2). Ive always had a fairly noisy top end. The dealer said it was within specs, blah blah.I suppose a high volume pump might help? oil
Thanks for the question, I'm guessing you have a twin cam and not a Evo since they made both in 99. Top ends on both have tendency to be noisy. I have a 2000 tc, rebuilt it also added the high volume pump. After about 25,000 miles the top started to get noisy again. The high flow pump may quiet it a little but you'll still have some noise. Hope that answers you're question. Thanks for watching and ride safe.
Hey Tinker how are you? I have an 06 Softail and also changed out the mechanical tensioners with hydraulic, and the kit did come with the new high flow oil pump, my question is how much PSI difference is between the old style,99-06 pump, and the new high flow pump that I installed from Screaming Eagle, what would be the norm on your oil pressure gauge, it's a stock twin cam 88b motor Thanks from Fl.
Hi Scott, from the screaming eagle kits I've installed idle psi is about 15 psi, under power is usually around 30 to 35 psi. So the biggest change you see is at a idle. PSI increases from 9 to 10 PSI to 15 PSI. Under power doesn't change much from stock. The biggest difference is you have a lot more oil volume in your engine which helps cool it down. When you start it cold you may see the oil pressure jump up to 45 to 50 PSI but as it warms up the pressure drops to the pressures that I stated above. Hope that answers your question. Be safe and stay cool in Florida
I have an ‘06 FXDBI Dyna after it sits for a while, several days, the oil pump won’t pump oil. I have to use a manual hand pump to draw oil thru the sending unit port then the oil pump puts out 25 lbs pressure. It has 12,400 miles on it. It’s been in a garage all this time before I bought it. Any ideas what’s causing this?
Thanks for the question, without seeing the bike it's a it's tough to diagnose but I can try and steer you in the direction to look. It could be a number of things. It sounds like the oil pump loses its prime after sitting and once it is primed it's should have 32 to 35 psi oil pressure cold. The Dyna in 06 was the first year of hydraulic chain tensioners. Where I would start would be the oil pump. It sounds like it's just worn out even with the low mileage, check the scavenger gear for wear or possible obstruction. Also check the cam plate. Check the pressure relief valve to make sure it's not stuck open. Inspect the cam plate for small cracks. It could be anyone of the above or a combination of the 3. I hope this helps you. Thanks for watching.
I just start watching your videos. They’re awesome brother. My question is 2004 Fatboy oil light went on so I changed the oil in the filters same problem. I change the sensor same problem. I didn’t hear a change in my motor. How do I know if my oil pop is truly working Before I spend the money on somebody redo it very much for your help.
It's possibly the sending switch. You'll find that down by the master cylinder for the rear brake. Get yourself a paper clip and open it up, unplug the sending switch. Stick the paper clip into the wired plug the 2 contacts in the plug. That completes the circuit. Start the bike if the light goes out it's a bad sending switch. If you're concerned about the oil pressure remove the sending switch and get yourself a oil pressure gauge and screw it into where the switch was and start the bike, that will give you a accurate reading on the oil pressure. Also on those earlier years when the bike is throwing a code the oil light will come on. To check the code hold in the mileage button on the speedo head. That will give you the code. You can than look up on the Internet what the code is for. Hope this helps. Thanks for watching.
When my bike has been running for awhile and I get to a red light it drops down to almost 0 psi is that a very bad thing that's when I know it's real hot.
Thanks for the question. Let me ask what year and model is your bike? And what does the oil pressure go to when you are under power? This will give me a little more info to answer accurately.
@@tinkeringwithharleys my 2006 ultra classic does the same thing after it’s been running awhile at a stop light. Drops to just above 0 and while under load it is about 32-35. I run synthetic oil. If that makes a difference
That is how the stock oil pumps run. At a idle the oil pressure drops to between 4 to 8 psi. Running synthetic oil is great for the motor. But what you're saying is normal.
when replacing rocker lockers on my 02 dyna on the rear cylinder is it necesscary to collapse the puchrods when you take the rocker support out or can you do it without doing that? Thanks very much
Thanks for the question Steve, nope it's not necessary to collapse the push rod or lifters. If you have adjustable push rods you may need to adjust them after you install the lockers and reassemble everything. If you have stock push rods you don't have to do anything. Also after you torque the rocker platform down give it about 20 minutes to let your lifters bleed down before firing the bike up. The lifters will refill with oil when you fire up.👍
Man I love your videos, no bs. I need to ask your opinion. Would you install a high volume oil pump like S&S or any other brand in a fully stock bike? I was replacing the chain tensioners and since I am there I was thinking it would be a good idea to upgrade to a better pump. Not doing anything else, no cams or plate.
Glad you like the videos. I have in the past installed high volume oil pumps on stock cam plates and 9 out of 10 develop issues and have to go back and install the upgraded cam plate. So no I wouldn't recommend installing a high volume pump a a stock cam plate. It's a little pricey to replace the pump and cam plate but worth it. Thanks for the question and thanks for watching.
@@tinkeringwithharleys thank you so much for the quick response, I valued your opinion. I am actually looking at this combo from Feuling Feuling OE+ Oiling System For Harley Item: P401953 it comes with pump and cam plate it seams like a good deal at a decent price.
I have a Feuling pump & cam plate in my 2000. I also camed it. I've run it for 6 years and about 50,000 miles and never had a problem. Also Feuling has great customer service. When you call them with a question they put a mechanic on with you, and much to my surprise they make follow up phone calls. In my opinion Feuling and S&S are the 2 best out there for the money.
Hi Clark, yep you can convert you're 5 spd to a 6spd on you're sporty. I've never done it myself, but I understand Baker Drive Train makes a kit to get 6 gear into it.
Hi Duane good to hear from you. The answer to your question is no. That pump is not on the Evo engine. The Evo uses the old style oil pump where the pump is on the exterior of the engine. The pump I show in this video is strictly for Twin Can engines. Harley made both the Evo and Twin Cam engines in 1999. Hope you are well.
I need a 2006 88b oil pump, I took my bike in the shop,its been sitting for a few years after cartic arrest I wasn't able to move it or ride it, back to the bike, harley said its complete corroded, the bike has 5300 miles, they say harley has a backlog of a month and a half to get one, is corrosion common that can last up to 100,000 miles? I need one.
Thanks for the question. Sorry to hear about your health problems, hoping you've recovered. This is a first I've ever heard of a oil pump being corroded. The twin cam 88 has a internal oil pump which is in a sealed engine. The only thing I can think of that would cause this is if moisture got into to the engine. If that's the case you'll need more than a oil pump. The stock oil pumps usually last about 50 to 60,000 miles. So the short answer is no this is not common. Like I said I've never heard of it before. Thanks for watching
@Tinkering With Harleys the reason it's in the shop is the gas tank leaked all over the inner and outer primary cases went under the black paint that bubbled it up gross looking lol. The shop said it's from the gas but that's the other side..any comments on that case?
The only thing I can think of is someone spray painted the case at one time. From the factory the paint they use is baked on to the case, and usually wears very well. But that should have no affect on the oil pump
@Tinkering With Harleys I just got back from harley, Big Miss information from a very smart new guy, but no, it's the fuel pump, not the oil pump, and was also told it's powder Coat not spay can..so dang I was very concerned and thank you for getting my ass off the couch to go down there and ask questions from the other staff .thanks, Tinker, for your input.
Never been a fan of the internal oil pump, I've replaced dozens of them. I always replace with S&S or Feuling unless the customer doesn't want to go that way. Thanks for watching and ride safe
@@tinkeringwithharleys So I have a question if my engine is dumping oil out of the carburetor breather and my oil tank is going dry would that be a sign that my chain tensioner went out on a 2001 twin cam ?
If you have the spring loaded tensioners and they've failed you would hear it and the bike would run bad if it ran at all. Failed tensioners when the pieces run through the motor it destroys the motor. If you're dumping oil through the breathers I would check the breathers heads. Also if you've had some recent motor work done and a passage has accidentally been blocked that would cause the high pressure.
@@tinkeringwithharleys has good compression and does not smoke when I take the air filter off probably just bring it to a shop I live by Casa grande Arizona and there is one shop in the area that seems to be really good
I'm guessing the breathers in the heads are clogged which happens time to time. There are a number of excellent shops in the metro Phoenix area that can tell you exactly what's going on with you're bike. If you believe the tensioners are going bad to not start or ride the bike it can cause catastrophic results.
Great, it's normal at a idle for the oil pressure to drop to about 8 or 9 psi. Once your under power the oil pressure should go up to 30 psi. This is how the stock Harley pumps work. They rely on flow not volume. As long as your not hearing a noisy engine at a idle your pump is working exactly the way it was designed to. Thanks for the question and thanks for watching.

Also if you've had some recent motor work done and a passage has accidentally been blocked that would cause the high pressure.

has good compression and does not smoke when I take the air filter off
probably just bring it to a shop
I live by Casa grande Arizona and there is one shop in the area that seems to be really good
I'm guessing the breathers in the heads are clogged which happens time to time. There are a number of excellent shops in the metro Phoenix area that can tell you exactly what's going on with you're bike. If you believe the tensioners are going bad to not start or ride the bike it can cause catastrophic results.

Thanks for watching
I have a 97 ultra classic EVO
Great, it's normal at a idle for the oil pressure to drop to about 8 or 9 psi. Once your under power the oil pressure should go up to 30 psi. This is how the stock Harley pumps work. They rely on flow not volume. As long as your not hearing a noisy engine at a idle your pump is working exactly the way it was designed to. Thanks for the question and thanks for watching.
