Zzeal Posted October 24, 2010 Share Posted October 24, 2010 I borrowed a pilot bearing puller from a garage where a friend works. Otherwise, I was going to pack as much grease as possible into and behind the bearing, start a short hardwood dowel as a snug fitting input shaft, give the dowel a good whack with a small sledge to force the bearing out. I've heard the technique works and for fun I wanted to try it. The trick would be in coming up with the right sized dowel. Steve Quote Link to comment Share on other sites More sharing options...

ktm Posted October 24, 2010 Share Posted October 24, 2010 Like I said over at Classiczcars.com: Go to Autozone. Ask to rent the pilot bushing puller. I am not kidding. They ask for a deposit, you spend 2 minutes using the puller, return the puller and get your deposit back. Quote Link to comment Share on other sites More sharing options...

theguppies Posted October 24, 2010 Author Share Posted October 24, 2010 Zzeal - i tried the grease method and got zero luck. jammed filled with grease and stuck a 5/8" bolt in there. the oil just squats right out after my hammer smacked it ktm - i did visit a o'really and autozone. both of their pilot bearing removal tool was too big to fit in the hole. soooo SAD tonyd - i agree but it would suck newzed - link is broken Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 24, 2010 Share Posted October 24, 2010 Stop grease and bolts. Find something that fits TIGHTLY. A wooden DOWEL will do it, but a piece of appropriately sized rod stock will work. If grease is 'squirting all over' then you got something that doesn't fit closely enough, and are not holding it straight. You have to let it pilot in enough to let it go in straight and then hit is SMARTLY (if you worry you will hit your hands, grab it with a vice grip!) I started with wet toilet paper, actually and not grease. Makes less of a mess. Sopping wet, the toilet paper is semi-colloidal and works just as well at building hydraulic pressure. I have never used a pilot bearing puller. They have nice ones now. But an old input shaft, a hammer and some sopping wet toilet tissue or THICK grease (stick it in the freezer) will hydraulically force the old bushing out with little fuss. But only if you have a decent seal on the forcing plunger (input shaft/bolt) to the bearing housing. I have seen at least one technician who chucked his assortment of input shafts into a lathe to knurl the shafts, and cut O-Ring Grooves in the pilot bearing end. Said it helps hold the shafts in there when he's aligning clutches (uses light oil on it I guess), and makes for a TIGHT seal when he uses the same tool to remove old bushings---you guessed it, using thickened grease. Though he mentioned in one case he used wet sawdust (?!?!?!) I would not recommend that substance, but I can see how it would work if that is all you had access to!

ktm Posted October 25, 2010 Share Posted October 25, 2010 ktm - i did visit a o'really and autozone. both of their pilot bearing removal tool was too big to fit in the hole. soooo SAD Then they must have had a tool with missing parts or a different one altogether. The tool I rented from them to remove my pilot bushing was adjustable. Quote Link to comment Share on other sites More sharing options...
theguppies Posted October 25, 2010 Author Share Posted October 25, 2010 they are adjustable. i minimized it to the max and it was too big. im' going to rent it and shim it down to make it fit. hopefully they don't notice when i return it. =D Quote Link to comment Share on other sites More sharing options...
NewZed Posted October 25, 2010 Share Posted October 25, 2010 Sorry about the bad link. It was just the search results from searching the words - remove pilot bushing. Interesting reading, everything from wet toilet paper to brown bread. I used a long lag bolt, screwed it in to the pilot bushing, then used a large crescent wrench as a slide hammer to tap it out. It only took a few taps. Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted October 25, 2010 Share Posted October 25, 2010 Yipes! Lag bolt... I've used a dremel to cut a pilot bushing out, and it worded but was a pain and I have perminent scars from a bearing puller, not to mention Autozone said they wouldn't loan me any more after I'd broken the teeth of two of theirs. Much later I had to pull one again and found that a 14MM deep socket was just the right size to fit in the center of the bearing, pumped in a bunch of grease (no chilling) and smacked the end of the socket (now also filled with grease) and an extention to plug the hole and pop! out came the bearing easy peasy...

z2go Posted October 26, 2010 Share Posted October 26, 2010 Youtube it, there's a guy who stuffs soggy paper in the hole, and slowly pounds on the paper (pretty much like the grease and dowel method, but with paper). Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted October 26, 2010 Share Posted October 26, 2010 It is easy. The trick is getting a tight fit, just like TonyD said. Oh and if you use grease you can use brake parts cleaner to clean it all up before putting your clutch back together, you don't want any grease on your clutch surfaces.

theguppies Posted October 29, 2010 Author Share Posted October 29, 2010 (edited) the best $12 investment i made. took a few seconds to remove it Edited October 29, 2010 by theguppies Quote Link to comment Share on other sites More sharing options...

theguppies Posted October 30, 2010 Author Share Posted October 30, 2010 It's a "clutch pilot bearing remover" according to the label. First you screw it into the pilot bearing then you pump grease into it. Magic happens after a few pumps of grease Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 31, 2010 Share Posted October 31, 2010 (edited) That tool is cool as hell, and makes perfect sense---is that a tapered thread to allow use on various bearings as well? Obviously if that works, it wasn't in that tight! Hammering the grease spikes pressures pretty high, much higher than most hand-pumped grease guns (or toilet paper sogged with water...) Two Questions: 1) Where did you get it. 2) How much did it cost-it's an Amazon Photo so was that total cost delivered, or what? I must have one! Just because it's cool.

Daemione Posted November 1, 2010 Share Posted November 1, 2010 (edited) It's a "clutch pilot bearing remover" according to the label. First you screw it into the pilot bearing then you pump grease into it. Magic happens after a few pumps of grease I saw those when looking for an inexpensive pilot bearing/bushing remover . . . But the ones I found said they were only for use on brass or bronze bearings, not steel. I found that a 5/8" wooden dowel is an EXTREMELY tight fit in the bushing, so I'll sand it down until it can barely slide in. If all goes to plan, I'll be trying it out this afternoon . . . wish me luck! Edited November 1, 2010 by Daemione Quote Link to comment Share on other sites More sharing options...
Tony D Posted November 1, 2010 Share Posted November 1, 2010 5/8" = 15mm 0.625" = 0.6122" This explains the 'close fit needing to be sanded down a bit'! If you have a lathe you can make it niiiiice! Quote Link to comment Share on other sites More sharing options...
