Hi everyone..

Just wondering if anyone here has pulled a Losmandy GM8 to bits for a re-grease etc?

I got my hands on a GM8 yesterday that has not been used in quite a few years, both axis of the mount were stiff and upon a close inspection of the worms, the grease has dried up into a glue... This is no concern, being that the mount hasn't been used in quite a while, it was to be expected..

Now, I've stripped the mount down to bare bones, cleaned everything with de-greaser.. There are two large roller bearing inside the RA shaft housing, and inside the DEC shaft housing that I can't get out... the ones in the RA housing look clean and the motion seems smooth, the ones in the DEC housing are stiff... I can't get to them try and clean them or if need be, replace them. Any ideas?

Other than those bearings, I must say Losmandy mounts are a dream for the home tinkerer.... If you have a set of imperial allen keys, the mount simply falls apart piece by piece until it is a shadow of itself...

Another part that needs to be lubed and or replaced is the bearings holding the worm into the worm blocks... the worms spin freely, but there is a slight grindy feeling to the bearings. These, I could not figure out how to remove...

Now that its all sitting here, ready to be lubed and put back together.. I am confronted with a question that I really should have asked before starting the job... What grease should I use? Anyone have the name of a product and where to buy it on the top of their heads?

Cheers..

Alex.
