distributor lock bolt stripped

Post by birdacre » June 26th, 2018, 5:58 pm

my 28 aa has the lock bolt stripped that comes in from side of head. any ideas on heliocoils, good bad? or do i tap it a bit larger. it appears to be a model B distributor housing because the condenser is exposed and not inside a cast tube like my other model A's. any ideas? this is the bolt with slotted head that has the larger locking nut that goes on last.

I see no problem with installing a helicoil. I did one for a friend a while back. Put a rag in the distributor hole to catch metal shavings and then vacuum them out before removing the rag.

helicoil is good. Probably a standard, recommended repair method. Do it.. ( But like mentioned, watch out for chips getting inside engine. Rag or Magnets work well also).

i just drilled it out, tapped it and put a stud one size bigger, works great and cheaper than a heliocoil. could not believe the price of a heliocoil.
