I took it apart today found that the counter shaft bearings were bad and that the 1st-2nd syncro ring was cracked (not the brass part but the ring that the brass ring sets in) that explains why i couldn't get it to go into 1st without it grinding, and i think somebody has has this thing apart before because it has koyo japanese bearings in it, also i found out that i have a luk clutch but it still don't hold the power.

 

do you have the book?

when the clutchs get old the pressure plate wont hold the power anymore.

 

Lots of folks running with Koyo's with good luck, but to each his own. Luk clutch= Measure the disk. It's likely 12.25''. Throw it out and replace it with an original Sachs unit or a 13'' South Bend unit before you put that tranny back in.

 

My uncle is a powertrain engineer at american axle, and he told me when I was doing my getrag that Koyo makes the best bearings in the world.

 

Koyos were in mine when I took it apart a few months ago. I would bet they were stock from the factory. And I believe they are a good brand. Parr with timken I would say.

 

Koyo's are the only bearing you can get for the Getrag. I've found I can all of the getrag bearings locally for about the same price as a kit plus shipping from www.zbag.com. In the kit you get front and rear oil seals, front 'freeze' plug, pto and top cover gaskets. I suggest buying a bearing and synchro kit and shims from zbag. They also have good used and new parts. That 1/2 synchro assembly is not cheap, about $300 used or new.

 

Mine has F A G bearings in it, I got them a couple years ago. They are German, good quality stuff.

 

what do you guys think of maybe tig welding the syncro assembly back together, i don't have the book but i have acess to the mitchel ondemand 5 program on the internet but i still wouldn't mind having the book.

 

PM me your e-mail address and I'll send you the .pdf of the Getrag part of the FSM. It's what I used to rebuild mine.

 

or you can pm me your e-mail and i'll send it to you

 

Don't mean to hijack but what does everyone recomend for getrag lube brand and weight
