Hi - I just replaced the weights in my clutch and would like to replace the rollers. It looks like I have to remove the spider so I purchased the tool. There are no directions and it looks like it would be easy to wreck something if not done right. Can anybody help me out with this. Thanks!

The spider is torqued to 200 - 210 ft-lbs and they use green Locktite on the threads. You will need a clutch holding fixture as well as the spider tool and long breaker bar. It should require a great deal of heat on the threads to soften the Locktite enough so as not to ruin the threads when breaking them free. It is critical to get it back together properly and to not damage anything during disassembly. Not getting it right can be very dangerous. I think this is why many people will get a new clutch when the rollers need replacing.

Is the spider and lock nut both threaded onto the sheive , if so are both torqued and are both locktite ? Also I was wondering if I could make a plate bolt it to the back of the sheive to hold it in the vice looks like there are six 1/4-20 threads on the back.
