Can't really say, but the advantage of the kevlar bushing is that even if it gets worn, the input shaft won't get trashed. I just changed out my clutch, which had the kevlar bushing in it, and the bushing was over 80 thousandths oversize, which caused a buzz each time the clutch was disengaged. The nose on the input shaft was fine. I put another kevlar bushing in.What's better? the South Bend Kevlar bearing and a quick dress with 600 wet dry or the pilot saver bushing and sealed bearing kit on Ebay?
You can't replace the input shaft bearing without splitting the tranny case. Its race gets pressed in from the back side, and needs shims to get the bearing preload correct. The cost of the bearing is miniscule compared to the labor to basically rebuild the tranny. I wish it was as simple as unbolting it from the front. The input shaft seal can be replaced, however from the front.How hard to replace the front bearing on the ZF-6 while it's out?
Does it come out as easy as a front bearing on a Munci M22 or BW T-10
What does that bearing cost?
