Title: Engine Spacers
Post by: Gingersaurus on March 28, 2018, 04:45:50 PM

Hi guys,

Anyone know what size the spacers are on a 81 r65? Had to cut mine off to get the engine out. Still got to get the stud out somehow (anyone got any ideas) but I'd like to get the bits ready.

Cheers

Chris

mix up 50~50 Acetone and Dexron III transmission fluid and bathe the stuck stud with it day and night. After a few days use a hammer to see if you can induce some movement and use more of your penetrating oil mixture to induce more movement.

When you eventually get the stud out, use a stainless steel (ground) replacement and coat it with your favorite copper based anti-seize compound.

As far as spacers go it is a bit of a raffle. Your bike may or may not have had "solid" mounts, or it may have once had cone-couplers. The size of spacers is really down to what your bike needs as the frame hoops may have been closed up, or spread, by past owners doing stuff.

P.S. If when you have it back together your bike is one of the rare ones that gives you "tingles" particular rev ranges - vary the tension on the engine studs to move the vibration to a rev range that doesn't annoy you.

I have used this and it works a treat. In tests it was the best unseizeser

Did you try pulling  it by removing the nut on one side and tightening the nut on the other side untill you run out of threads and add spacers and tighten again and repeat the process until it comes out
Maybe even working it back and forth while applying penetrating oil should have gotten out

If it would not  come out doing that
Then  that  thing is really stuck and may require drastic measure to get it out Like machining or heat

Be careful beating it out
If you mushroom the end It is really going be tight

I assume this is mostly a problem with bikes that have sat  for a long time exposed to the weather

Hi guys,

Cheers for the help, ended up having to use a pillar drill to get it out. It was a nightmare.
