mechanical ta replacement

Posted by jd jim a on May 04, 2007 at 22:00:48 from (24.180.143.209):

I'm doing my first mechanical TA, on a 686. Got a couple questions- I got a complete rebuilt unit with a gasket kit. The kit included four seals. One is very large and obviously fits in the housing between the TA clutch and the planetary. Two are the same size and go at each end of the top PTO shaft. The fourth one is small, same size as the one that goes in the planetary, between the input shaft and the carrier. Why the extra seal, or am I not seeing something? When I install the new TA clutch disk and pressure plate, will the pressure plate levers require adjustment, if so, how? There is a straight roller bearing on the top transmission shaft right behind the TA. I have heard it is a good idea to wrap a rubber band around that bearing to avoid knocking the rollers out when reinstalling the clutch housing to the TA housing- is this true? What happens to the rubber band, does it just slide back and stay between the bearing and the gear? Last question, I removed the hyd pumps so I could powerwash the clutch housing. The dealer says there are two different thickness gaskets to go between the hyd pump mounting flange and the clutch housing. Says this contols the backlash between the pump gear and PTO shaft gear. Says the thick one is most commonly used. How do I tell for sure? I have an I&T book but it is quite vauge.
