Re: NV4500 Throw Out Bearing

Hey Captain. I had never seen a return spring with any of the stock clutch configurations that Ive run. Even on my current set up with the Adv Adapters BH, the entire deal is hydraulic. No return spring.

Is there a chance that either the master or slave is hanging up somehow?

It is kinda weird though that its making enough contact to spin it with the pedal out yet when you disengage the clutch, it was silent? I get what you're saying in that its "not a good idea" for the TOB to be spinning while the engine is running all the time. Sort of like riding the clutch would wreck a TOB.

I can't see how a return spring would hurt. Especially if it was on the outside of the BH where you could take it off if needed.

I do know that the "inspection plate" for that is virtually useless for any kind of "inspection".

Id also say that while you're getting into it, change out the magic elixir trans fluid for new stuff and add an extra quart through the shift tower for good measure.
