Title: repair inner clutch basket threads?
Post by: Greaser Greg on December 20, 2019, 04:11:57 PM
Stripped a bolt/screw hole in the pressure plate.  Helicoil or toss it?

Do you mean in the hub? Where the 6mm threads are? The towers with the 6mm threads in them?

yes, sorry. tower where the bolt fastens through the plate.  one of the six holes is stripped.  Is there a torque value for those?  one of them always seemed kinda funky.
don't want to wreck the basket from my other engine.  Lowest recommended torque and blue locktite looking good at this point.

No locktite on the clutch bolts needed.
If you use a helicoil, use red locktite to keep it in

Which style basket do you have? Maybe I have one.

Joe is asking 6 plate (spider hub) or 7 plate (bolted back plate)?
All RD350's are 5mm X .8 threads (except RD350LC and RZ) not 6mm X 1 like the 400's.
I wouldn't try to repair it with a helicoil as it will be very weak and break boss mount off.

I disagree... a true helicoil is a wound coil and is held in by tension from it being oversized and needing a installer tool to install them in the smaller sizes. They do not use loctite.
Now a thread-sert or time-sert, yes... you can use loctite as they are a threaded body insert not just a spring coil.

Yes, pic is there... but angle is wrong to see it.

How's this?

Post by: SUPERTUNE on December 20, 2019, 11:31:39 PM
Perfect!
I would have to tear some core engines apart to see if I have one if Joe doesn't have one...
The one I know I do have... I used in the clutch postings is broken.
