I know this is an old thread but if your still stitching it would be good to hear any updates on the Hydraulic Throwout bearing (HTOB).
I looked at a few different HTOB's and at prices that varied across the board from $99.99 to $300+ After a couple of discussions with a few performance parts suppliers I opted for the $99.99 version. It arrived and looks very well made. You can check it out at the following link

It's interesting that the instructions are virtually identical to the Howe unit#82870 I wonder if it's made by them?
Anyway, The correct spacing adjustment process is done by a number of 0.050" thick cone shaped washers. Once I've got the spacing correct I'm thinking of machining up an aluminum spacer to replace the washers. Seems like an acceptable thing to do? Anyone got an opinion?
Also the installation calls for no clearance between the clutch fingers or slight pre-load. Why pre-load? The TO bearing would spin with the motor and would that not lead to a shorter bearing life?
Wold love to hear back.
