Someone was telling me that years ago they had a g11, and found that they needed to clean and re-lube once a year. Is this recommended??

Like all things it depends on your use, care and conditions. Also depends on your mount, older straight drives are more exposed to the elements than later tucked servo OPW mounts. But once a year seems excessive to me. Maybe every 2-5 years depending as above.?

Thanks, I'm using a newer GM811G, maybe a year old or so. I store it indoors, and? take it in before I go to sleep, so it's got minimal exposure to the elements. Seems like I've got some time.?

Sounds well cared for Jamie.
I'd be inclined to not worry for 5 years.
The minimal motion use of our mounts is really very light duty to the lube.
And I believe it is a synthetic, so it should retain it's lubricity for many years in your ideal type circumstances.
I know Brian has mentioned what Scott uses for the mounts. Hopefully he will weigh in again.

Hi Jamie,
Sounds like you care for the mount as I do, I keep it covered when in the field and not in use. When it is not in use it is stored in the house also covered. If you do this and you have used SuperLube on the mount bearing you can go many years without needing to clean and lube again. Of course if you get caught in a sand storm - it depends. If you have SuperLube the lube itself will never wear out in this application. But contamination is the problem and it takes years to accumulate unless exposed during an unusual severe event like a sandstorm. But even then if the mount is well covered and protected chances are good it will be fine for many years.??

Thanks. Well, I guess I can't blame my poor guiding on the lube then:P
RA was getting quite bad all of the sudden, and I was scratching my head trying to figure out why. Dec was just peachy. I think that I found the issue last night though. I am using the newly discovered (to me) PEC algorithm in PHD, and I did not set the flag to not auto calculate the period, so the period went to the moon. I can't remember the number but it was really high. I set it back to 239.34, and told it not to do an auto calculate, and everything went back to normal again.?
I found that info in one of the posts here, can't remember where, but thanks!

The PPEC auto adjust period option in PHD2 is a tricky thing
I think they originally designed it for people who didn't know the period of their mount, so it would "figure it out"
I've often found it goes into the 800 second or more periodicity, which to me is kinda crazy and gets into polar misalignment territory.?
My best results are likes yours when I enter the worm period and disable auto adjust option

Well, glad to hear I wasn't the only one that got caught by the Auto calculate period check box. I thought I was going nuts, kept changing it to 239.34, but it kept going up. Finally saw that the box needed to be unchecked.?
It wasn't terribly bad for me though, even with auto calculate on. I had the predictive weight set at 30 and reactive to 80, so it was mostly just reactive.

Hi Jamie,
I also use Superlube, but have not been active for past five
years since my dad's health took a downturn.

Jamie,
Balance your scope loosen the clutch knobs all the way, and see how smooth the action is, if it is slightly sticky clean it, if it is real smooth leave it alone.?
Check the worm gear and touch the grease, if it is sticky clean the grease out of the system. If you live in the cooler areas of the country? as I do, use Lubriplate No. 105 Grease.
If you live in the hotter areas you will need a thicker grease.?

Nels,
You do not need to use anything other than a single grease if you pick the correct one. Super Lube with Teflon uses a pure synthetic base oil and will not run when hot or get stiff when cold. You can try it and see for yourself, put a dab on a spoon in the freezer for a few hours and when you touch it it will be just as soft as when at room temperature. Take that spoon with grease and heat it up in the oven set to 150F degrees, it will not puddle and run off. You want to use the NLGI-Grade-2 rated synthetic base version not the Silicone based grease even though it is a slightly better base oil. Silicone is impossible to clean in a household environment and is a source of serious contamination that keeps migrating all over your work space and you cannot get rid of it without bad chemicals, trust me on this. Or just Google silicone contamination, it is insidious if you paint, solder etc.?

FYI Losmandy generally recommends a synthetic grease, preferably that has teflon, and meets your temperature range requirements. We use jet-lube MP-50 low friction moly paste. we do not recommend lithium grease

I've had my G-11 for over 20 years. I had one failure about 15 years ago on a night where the temp dipped to -15¡ãF (-26¡ãC). I cleaned and re-lubed the mount with Slick-50 One Grease (which was the hot ticket back then) and never had a repeat issue. Of-course - YMMV.

Brian,
MP-50 is a stiff, heavy clay thickened lube and is not a synthetic based grease. As I've posted before MP-50 is not as good a lubricant, just check out the TDS sheets for MP-50 vs SuperLube, particularly the 4-ball test, cold start torque and cold viscosity. SuperLube consistently offers better specs and has been much more fully tested under more conditions. In this application IMO SuperLube is a much more suitable grease.?

I use Corning 33 which is used on Mars rovers, for my Montana
winters.? Some of the clearest weather I get now is winter, rained last
night.
?
But as hot as the rest of the country is the M50 is maybe OK.
?
MP-50?may
be applied directly to hot surfaces without running
off or dripping. Conversely, it may be applied at temperatures
as low as 0¡ãF (-18¡ã°ä).
MP-50?is
water resistant,
withstands extreme weather elements, and helps prevent
corrosion onparts
exposed to water, steam, most acids and alkalis.

Leroy,
We're not on Mars and Dow 33, now called Molykote 33 is still a Lithium and Silicone oil base. Lithium greases dry out and Silicone oil is a weak lubricant that separates and runs all over the place including the clutches causing slippage problems. Read the data sheets Molykote 33 is not as good a lubricant as SuperLube pure synthetic with Teflon. SuperLube also has an extremely low cold startup torque and won't freeze or melt off the bearings or worms at least not on Earth.?Dow 33/Molykote 33 was the only game in town 25-30 years ago when full synthetics were not widely available but Dow 33 has long since been surpassed.??

To summary, SuperLube Teflon perhaps is the best. Where can I find it? Not in Amazon, nort in SuperLube.com.

Chip i've discussed this with Scott many times and he certainly sees it differently.
i'll see if he has any other details he wants to weigh in with

PS i should mention that we've tested literally dozens of lubricants over the past 40 years doing these mounts. Probably even more than that

For the people who are looking to buy Super Lube here is some information.?
Synco is the company that makes the Super Lube product. The full name is Super Lube Multi-Purpose Synthetic Grease With Syncolon (super small Teflon particles) I am using the NLGI-Grade-2 product, the 14 oz. tub is #41160/2 and a 14 oz. cartridge is #41150/2. You can also buy the same product in smaller sizes but the tubs are the cheapest per ounce cost.?
Regarding NLGI grades this is the consistency of the grease, NLGI-Grade-1 is like tomato paste or yogurt where NLGI-Grade-2 is like natural peanut butter. I have used both but use NLGI-Grade-2 stuff.??
