z-ya Posted November 25, 2009 Share Posted November 25, 2009 I'm getting ready to install my RB25DE which was originally mated to an automatic transmission. I am going with an RB20 trans because it is NA, and no trans tunnel mods are needed. I'm using an RB25 flywheel, and I have a Z32 clutch kit. I am trying to figure out the pilot busing. The pilot busing fits nicely over the input shaft of the RB20 trans, but the pilot bushing doesn't look like it will fit at all into the end of the crankshaft. The crankshaft has an insert of some sort. Do I need to remove this? It looks like the pilot busing wil be too small if I remove it. Is the Z32 pilot bushing the right one? Thanks, Pete Quote Link to comment Share on other sites More sharing options...
pat1 Posted November 25, 2009 Share Posted November 25, 2009 yes and yes you need to remove it and install z32 pilot bearing Quote Link to comment Share on other sites More sharing options...

GrayZee Posted November 25, 2009 Share Posted November 25, 2009 It is a real bugger to get out, I tried a few different methods but gave up and bought one os these... http://www.princessauto.com/tools/auto-repair/auto-repair/8105256-3-jaw-bearing-puller It worked like a charm!

pat1 Posted November 25, 2009 Share Posted November 25, 2009 I tack welded a bolt to the bushing and used a slide hammer to pull it out Quote Link to comment Share on other sites More sharing options...
RKLamb123 Posted November 25, 2009 Share Posted November 25, 2009 Man I hate those it took me two weeks of trying to get it out finally I use a dremel and cut it out. If you grinding it out into three sections you can then use a hammer and tap each corner and it will cave in then all you have too do then is pull it out took me like 45 minutes. I tried the slide hammer and the bushing pulling tool and could not get them to work. So just another option I guess. Quote Link to comment Share on other sites More sharing options...
RIPSNZ Posted November 26, 2009 Share Posted November 26, 2009 Or..........you could just get a 3-4mm drill and drill into the collar at 9 oclock and 3 oclock just the depth of the collar, then give it a tap with a sharp chisle at 12 oclock and 6 oclock and hey presto, she's out, all in less than a minute or 2 and with no swearing.

z-ya Posted November 26, 2009 Author Share Posted November 26, 2009 I ended finding a nut that fit snug into the bushing, then I welded it to the bushing. I took a long bolt and screwed it into the nut until it bottomed out against the crank behind the bushing. As I tightened the bolt it forced the bushing out. This is probably the easiest way to remove it. Took me less than 15 min to do it. Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted November 26, 2009 Share Posted November 26, 2009 Great idea! Quote Link to comment Share on other sites More sharing options...
Careless Posted November 26, 2009 Share Posted November 26, 2009 I didn't even notice that sleeve when I had my VG33 crank nitrided. Had the machinist not noticed it was in there before sending it off to nitriding, I would have had a heck of time trying to drill and remove it!
