Life saver! Did this on an engine to trans dowel. Not a blind hole, but filled with grease from the backside, threaded in a bolt to seal, and it worked perfectly. Thanks!
That is awesome, I'm glad the video helped you out.
I consider myself mechanically savvy and got As in college physics yet if someone on the street told me this method without me visually seeing it I would have laughed at the idea. Truly amazed at this.
You might want to add a little to this video. You can't leave the grease in the bolt holes you could potentially crack the block when bolting the heads on. So be sure to blow all the grease out and clean hole with solvent.
Yes. And the drill bit turned around and twisted in clockwise by hand and pulled straight out would help get the bulk of the grease out before blowing with compressed air.
this method also doesn't work if the holes aren't blind (aka go all the way into the water jacket) like on some engines.
Oh my god I can't believe this worked so well! I stripped two bolts on a camplate where both dowel bushings are and was having a very hard time removing them. Remembered watching your video and was able to punch these out and get the heli coils installed! Thanks so much for posting, this trick will stay with me forever.
Glad it worked out for you yeah. I was amazed the first time I saw that forty years ago.
There are a lot of videos on how to remove dowels using brute methods, I do not understand because I tried this method explained here myself and it is like a magic trick that works in any size. Later I cleaned the grease with brake cleaner. Congrats on sharing this.
I just love it when a plan comes together😁👍
It does seem like a magic trick.
Where the hell was this video when i needed it!!!! This is, without a doubt the best method!
Es una Riata señor (Spanish language) You're smart person. Thanks a lot. Regards from Monterrey, NL. México.
hi martin, thanks a lot for your video. This is gold information. In my country, no one is selling dowel pin here, and i tried my best for days to remove the pin without destroying it. will try your method, thanks again!
Hi Wilson, glad you found my video now you'll be able to get those dowel pins out of there and be able to replace them as well. Thank you for watching.
Hi Wilson, glad you found my video now you'll be able to remove and replace the dowel pins and not have to worry about destroying them. Thank you for watching.
Rebuilding a 1980 Honda CB750, really trying to not damage the original dowels. Will try this in the morning! Thanks Martin
Good luck with the rebuild, and thank you for watching.
One of the best things I have learned in many years. Thank you so much
I'm really glad you like that.
it's a kind of magic... almost.
Great tip as I am learning to be a better engine assembler
I'm glad you liked it and found it helpful thank you for watching.
Great idea, using the hydraulic method.. O can't remember where on TH-cam I saw the mechanic stuffing bread into the hole to get something out, the idea was the same.
Hey mate used your method. Just ended up finding some 11mm rod and grinding it down on a drill press to 10.5(my dowel id) and it worked well. Cheers for the advice
That's awesome i'm glad you liked it and found it helpful.
Thank you for watching.
The one I need to remove is for a starter motor but it doesn't have a hole in it so this method won't work for me but I must say that is really cool. I'll have to remember this in the future. Great video!
Thank you, I'm glad you're like that. Sorry, it isn't made for the solid dowl pins.
Brilliant guy...brilliant ways
Thank you I really appreciate that 🙏
This worked really well for me. Thanks for sharing this ingenious trick!
You're welcome, glad it helped!
Wow this is awesome. Wish I could have seen this before trying a pair of needle nose vise grips but at least I knew I shouldn’t have done that. My dowel pin is in the bellhousing and has a hole on both sides but I can simply just have someone hold a block of wood on that side with their body weight. I’ll have to find something to stick in the pin and see if I can get my brand new but not working grease gun to work but that’s another headache.
Yeah with the whole Going Clear through the bellhousing you're gonna have a hard time removing it using this method because of the hydraulic pressure that is created by using this method is just gonna simply push whatever you're trying to hold on the other side.
If the whole goes clear through you might be able to use like a round punch and drive the and drive the dowel pin out.
That’s genius. Thanks for the trick
That's crazy! I'm 67 years old and that was very cool. Unfortunately, I have a motorcycle repair shop and most of the dowels are straight threw the cylinders on Harley's. Still awesome though! Hahaha
I'm glad you liked it.
That has always been a major pain in the ass! I actually cut notches out of my boring bar table so I didn’t have to remove those critters. But I know there will be a day that I will need to use your awesome technique. Thanks again!
Thank you for this video. I had to remove two dowel pins from a Subaru block and the first one I did the old fashioned way with vice grips and a drill bit. Needless to say that one is completely destroyed. I thought to myself that there has to be a better way to remove these things. Came across this video and voila, the second dowel pin doesn't have a scratch on it. Vice grip method = buying new dowel pins; grease method = holy shit, I can't believe that worked.
😉 Yeah it's like a kind of magic.. I'm glad it worked out for you.. And thank you for watching.
I knew that's what you was shooting for before I watched , that's smart
Thank you and thanks for watching
its a good idea. if nothing else works but very slow fill and clean out grease
Martinbuilt: you are the man.
Thanks Greg, I appreciate that.
Thanks Martin this really does work, got mine out today!
Glad to hear it, it's a kind of magic
Martin you are a genius!!
Thank you Freddy I really appreciate that.
I've been saying I'm a self proclaimed genius for years.🤣
Very cool have to remember that one.
Great methods
Thank you I'm glad you liked it and you found it helpful, thanks for watching.
old trick you can do the same thing packing pieces of sandwich bread in the hole. cool stuff
thanks for sharing this! newer seen this before will try it out tomorrow
Let me know how it turns out.
definitely one of the coolest things
Thanks I thought so
Llevaba buscando hace 2 horas este video, muchas gracias amigo me sirvió mucho
Awesome. 😱. Amazing 🤩. Thanks 🙏
I'm glad you found it helpful.🙂👍
Thanks for this. Worked like a charm!
Great to hear! 😀👍
Danke dafür das du uns teilhaben lässt.👌👍 Einfach cool und Danke für deine Tipps glg Daniel Förster aus der Steiermark 👍👍(einfach HAMMER)👍👍 Mit dir ein Jahr lang arbeiten das Wehre cool da könnte ich so viel lernen
glad you found it helpful and thank you for watching
Cool! I can do that. Might need to remove two from my engine block.
You can do it!
Awesome video! i pulled my head and the dowels are stuck in the cylinder head, not the block. Maybe 2mm revealing. I cannot find a puller small enough. -Any thoughts?
this isnt a comment on this video,BUT. YOU ARE A LIFESAVER I WISH YOU WERE MY FRIEND AND I 100% OWE YOU $$$$$$$
Thank you, I appreciate that!
That is ultimately cool. Nice done
It's a kind of magic.
Glad you found it helpful.
How do you remove all that grease from the bolt hole after you’re done?
What an Ingenious ideal! 🤩
thank you, I appreciate that.
Thank you sir
I'm glad you found it helpful 👍 I
Thanks. Great way to remove hollow dowel pins but how do you remove solid dowels. BTW, oil works better than grease since it doesn't leave air pockets.
Here is a tool made for solid dowel pins
amzn.to/37bbJ8a
@@martinbuilt I was thinking to buy this one but it will be a waste for a one time use. I'll try welding a threaded rod onto the pin, and use a steel tube, washer and nut to jack up the pin.
How do you get the grease out
Good one brother👍
Thank you. I'm glad you liked it and found it helpful.😊
Couldn’t actually get it to work, think that long grease nozzle, no air is crucial. Looks like pliers for mine🎉
Nice trick keep up the good work
Thanks, will do!
Such a great tip! Thank you!
Glad you liked it 👍
When I think of all the dowels that I buggered up.
Awesome bless you 👑
Thank you. I'm glad you found it helpful.
Any hydraulic fluid will do, well done mate
Thanks I'm glad you liked it. And thank you for watching
you can do this on spigot bearings on a crank
Yup that's where I learned it from.
천재급 생각이네. 와우
Really cool, I am indeed blown away, BUT, when they are solid? like I got one in my engine block that does not align with the transmission bell housing...well then like we say in ebonics, I am fucked! LOL...that said had to order the dowel extractor tool from amazon for a really nice comfortable price of $189.00!!!!, I know i can drill it, tap it then extract but the tool does work although very expensive
You got a trick to get the bell housing alignment dowel pins out of 40-50 year old Chevy blocks?
This should work for solid dowel pins. Dowel Pin Puller Set amzn.to/3yjXNFA
Suppose you could use the grease method to remove timken bearing races that are in a blind hole. Thanks for Sharing our Videos With Us.
Thank you, hope you found it helpful.
this is how we used to remove transmission pilot bushings
That's exactly where I learned how to do this. At a 4x4 shop that I used to work at.
Thank you for watching.
Cool
Dang, thanks for the tip!
it's a kinda magic
How are you supposed to get the grease out of the hole when you are done?
If it's on an engine stand turn it upside down and use some brake parts cleaner.
I was able to remove a lot of it by using a long skinny screwdriver.
Cuanto amor x el v8!!! Te invitaria un buen asado argentino y unos malbec y charlar de wjs por horas!!! Abrazo y gracias x las magias!!!
Argentine barbecue sounds good, thank you.
Mach bitte weiter so Danke
I will, thank you for watching
Thank you!! Those 4.7 timing cover dowels are hard to get. (Mopar part # mopar 53010533aa)
No dice. I broke both of them. I must have left air pockets or something. Then broke one with vice grips and the other trying to bottom a tap in the hole to force it out. I believe for the 4.7 timing cover alignment pins that the dimensions are 14mm diameter by 15mm length. That is what I have ordered so fingers crossed! This is holding up the engine transplant whole show!
That is a cool trick but what is the purpose of removing the pins? All I know is they are good to keep the gasket lined up and help line up the cylinder head. Really interested, not arguing any point at all.
If you are going to resurface the cylinder block using the block and sandpaper method the pins would have to be removed. Thank you for watching.
Very cool 👍👍😁
Thank you! Cheers!
Ohh I think we done this with wet paper and grease before to remove pilot bearings... sweet
Yeah I can see where that would work as well. The power of hydraulics it's pretty incredible.
Really cool trick, but the assembly dowels on my little Honda D15B7 engine fit into the cylinder head bolt holes. That would take a *_lot_* of grease. Ha!
This 4.7 is exactly the same as you describe your Honda the cylinder headbolts go through the dowel into the block.
Subbed!
Nice 👍
Thank you! Cheers!
Could probably do this with water as well.
Nice job Martin.Was that 4x4 shop in Iowa?
Yes it was, Cedar Rapids
Beauty
Nice
Thanks
That's the same way you remove a pilot shaft bushing on the old 350 Chevy standard motor
Yeah that's actually where I learned it from was removing pilot bushings from 4-wheel drive when replacing the clutch.
Do you know the part number for the 4.7 dowel pin on a 2002

@@martinbuilt Thank you Martin! I used a air compressor to clean the block and the dowel disappeared forever, never to be found. This helps me alot!
that's fucking genius man
Thank you. I'm glad you liked it and found it helpful. 😊
@@martinbuilt Two problems I've ran into - the drill bit size 3.5mm is slightly too small, the 4mm is slightly too big
And possibly a bigger problem, even if i can find the right drill bit end (prob 3.7mm, 3.8mm) the dowel itself is a sprung teeth type one, so that it can ordinarily be squeezed to install or removed. So probably, even if a drill bit fits, the pneumatic energy will be lost through that long side of the dowel. Not enough of the dowel is sticking up over the engine block (almost none of it is). IT sheared off somehow.
It's a head scratcher. I have spare dowels to install, but can't get that current one out :l
And what about solid dowel pins?
They make this tool for them, Dowel Pin Puller amzn.to/3cUbVfd
Hey Martin, this is a little of topic, but have you heard of rockerlocks? I recently dropped my valve seat and my rocker won’t lock in with my lifter. I was going to get a new HO engine but then was recommended rockerlocks on a forum. (Rockerlocks dot com) it seems like a band-aide but do you think it’ll last a couple thousand miles? Already bought some so either way I’m going to try it.
yes, it's a band-aid. I'm sure they will keep a rocker from popping off. Try removing a rocker after installing them. It won't help a dropped valve seat, the head needs to be replaced or fixed.
@@martinbuilt just thought I would respond after 2 weeks. I got the rocker locks and installed them, the rocker still wouldn’t stay on the lifter, it was too loose. Now I’m looking to trade one of my XJs for a 4.7 HO.
@@deeppowhazylab have you checked the valve spring?
@@martinbuilt the spring looks to be in good shape, but other than that I’m not sure. I’m not surprised if it dropped though, it was having overheating problems from the water pump going out.
In theory you could do this with bread
nice hack. way cheaper than a dagone pin puller
I'm glad you liked it and found it helpful. Thank you for watching.
Dude.
not for every one can easily destroy the threads
The threads are like 5 inches down inside the block nowhere near what I was doing.
Thank you for watching.
My luck, the block will crack ...
That sucks 😕
