Ovision worm cleaning/maintenance

G'day all....
I'm planning some observatory maintenance in a couple of weeks, so will take the G-11 inside and strip it down for some fresh grease, I think the stuff that has been in it the past 5 years is getting a bit sticky and is showing in the guiding....
I've stripped it down before, so know the basics, and will google for refreshers.
I added the ovision worm back in 2013. Has anyone had any experience with cleaning/regreasing this part? I know the manufacturer states its pre-greased and not to add anything when installing....


Thanks in advance....
Lee

I know you mean well but frankly don’t fix what ain’t broke.

Some worms are cut from oil-impregnated bronze - ie self-lubricating. You won’t improve it.o

I do remember improvements in performance after a regrease back in 2013, but the ovision worm has been added since. I won't be mucking about with it unless its obviously contaminated....

Rince with turp and a brush. Clean the gear the same way and only lube the gear. The worm will take care of itself.

Thanks, that's what I did before, I think I used some sort of degreaser? I ordered some Superlube on eBay, it seems to be the favourite, I used some Inox stuff last time, it seemed OK too.
Superlube on the gear as well?

I use MP-50 molypaste. I used superlube but the molypaste seems to be more resilient with water contamination and sticks to the gears better.

Would any molypaste be suitable do you think?

I've got this specific type because that's what they used on the now defunct Mountain Instruments mounts (MI-250), that was pre Losmandy G11/Titans, etc... Had a chat with the owner in the US at the time before they ceased operation.

I'm just re-reading this - would you rinse out the worm assembly?
and - where did you get the MP-50? I've found an Australian distributor but it's unclear if they'll sell retail.

Yes. Pull everything apart. Bearings, worms, everything. Bucket, tooth brush, turp. Get rid of all the old grease. Go for it. Once a year.
I bought one can from the US online. It's a lifetime supply.
