Re: Who Installed Their Own JB Conversions SYE???

Hey, I just finished the install. I'll have a write-up soon, god knows I got some stories to tell. [img]/wwwthreads_images/icons/crazy.gif[/img] I got the Advance Adapter kit from T. Woods though! The AA kit does NOT use the two needle bearings. You DO have to press them out with both kits but only the JB needs the replacement ones pressed in per their specs. I guess you could really just keep the old ones if they're in good shape. The AA kit uses the latest NP231 style shaft that has no bearings as per the design. You will need a press. It was another great use for my home made press and some seal driver disks I had on hand that were wide enough to sit on the bearing cages. I think they're like 2 1/4 inches dia so you'll need some pice of pipe or a monster socket or something to press them out with. So which kit do you actually have? Oh one more thing. You'll need THESE lock-ring pliers: http://www.armstrongtools.com/catalo...p?groupID=1009! This is no joke. The mode hub lock-ring is a beast to remove and install otherwise. You'll need not snap ring but lock ring pliers that'll open to 1 1/2 inches! I made do with a generic Lisle brand by bending the tips and two large screw drivers and some luck. I was going to actually modify the Lisle pliers by inserting a strip of metal in the joint to make it spread more I was so fustrated but at the end I got lucky. I also installed the Tera 2low kit and it works great. Last thing. Please, don't forget the spring on the shift rail! Naa, I'm not speaking from experience ...
