stripped a crankcase cover bolt out - ideas? By godfeast (Read 1,654 times)

I recently decided to tear apart and half-rebuild my dead 150cc sunl longbo.

During the changeover on the oil pump, I stripped out the hole for one of the crankcase bolts (stuck a longer one in by mistake) holding the right side cover on - sits above and to the right of the oil pump channel to the piston.

Has anyone else ever screwed this up and know what I can expect if I just torque down the remaining bolts?

I'm Thinking the bolt below and the one holding down the stator wiring might make up for the missing bolt with a little extra force (hopefully not enough to strip).

It's in a worst case scenario as far as position is concerned and having to change out everything to replace the left side case is just a disaster for me.

Maybe try to re tap it out with a slightly larger bolt size or a different course thread. I wonder if there is a fill material that you can use and drill and tap again

i would try a standard tread bolt the next size bigger

[godfeast]

drilling and tapping would require a complete tear down, which I just dont have time for now.

I think I might try the next size up on a standard bolt.

Thanks for the suggestions guys.

Take the bolt that belongs there and JUST GET a standard american none metric bolt and it works great.

I've never seen this stuff:

That would be a nice alternative to JB Weld if it works. Let us know how it shakes out. Rich

bought a standard 1/4" x 4" bolt and it worked like a charm guys.

THANKS!

The only problem I see with that devcon is the max temp is 250 degrees. Might be a close call for a water cooled engine but not ok for a gy6. I would love to find some thing that was in the 350 degree range that was affordable. Would like to make a few cooling fins that could be stuck to the bottom of a gy6. john
