Throw out bearing problem

it started when the Clutch cable on my (1989 tour glide Ultra classic)
broke. I had it replaced and after a couple of hours of driving the clutch handle went in but the clutch stayed engaged. had to float the gears to get it home. after getting it home found that the throw out bearing was tore up. last year I replace 4 throw out bearings and each time within 10 miles or so they tore up again. same thing each time handle would go in but clutch would stay engaged. the bike had a high performance clutch in it that had a lot of miles on it. so this year I replaced everything. the complete clutch assembly with stock parts. also the rods going to transmission side and of coarse another throw out bearing. drove the bike a couple blocks and guess what same thing. I have been told its an adjustment problem but I have followed step by step the adjustment steps. please help I can not afford to spend much more money on this bike.

Sounds like you are adjusting the throw out bearing too tight.

Constant pressure against the bearing from a too tight clutch pack adjustment is my guess.
A more radical symptom would be a bent or warped trans main shaft.
Try the search function up top for the proper procedure on clutch adjustment.

A simple test is.... How much movement do you have in the lever at the transmission end as mine has about 1/4 to a 1/2 inch free play. If you have free play there then in theory there is no idle pressure sitting on the throw out bearing.

There was an oil slinger mod to later Evo's that helps keep the bearing oiled and cooled. Not sure if they can be retrofitted, although I have one in my shed awaiting my winter tear down.

What gear oil you using? Are you using enough? Is there a oil slinger missing? Make sure of your freeplay.

[I'm sure its not an adjustment problem. how can I tell if the trans shaft is bent or warped? the rod slides through smoothly.
