Your lucky getting 10-15 years service outa those wafer bearing throwout bearings. I usually got about 250 MILES outa them. But thats with a 3 inch open belt drive and foot clutch.
I've been running the wafer style for years and years with few problems.
The trick it seems . . .
. . . is to ensure the throwout knuckle is hitting the thrust washer of the bearing squarely. That is, both fingers are touching at the same time. Otherwise, you're side-loading that delicate bearing and it's no surprise when it fails.
I'm sure you've noticed that the repop throwout knuckles are total fucking garbage. Looks like they hogged out the slot with a dull chisel and a ten pound hammer.
Put a straight edge across the kicker cover gasket surface and drop a mic or caliper end to each finger. Grind 'til they're equal.
There are two reasons I go through this (what must seem like a hassle to some people):
1) My trans/kicker will not fit an early style bearing. Modifying the cover to do so would take too much meat out of it and run an extended length arm on a big motor. No need to make the cover any weaker
2) The repop early style bearings are probably even shittier than the wafer bearings. They don't want to turn for shit (feel the grind when you turn it in your hands) and end up wearing down the rod from spinning. I have a four of them in a drawer from the last ten years and they're all like this.
Luckily I have three real ones also in a drawer for other projects.
