catman161 Posted January 16, 2013 Share Posted January 16, 2013 Hi guys, I took my polar scope apart today as whilst messing around with it I accidentally removed one of the grub screws and the reticule fell down and I had to remove the whole thing to put the reticule back in in the correct way up and get at a screw that in turned too much and it ended up going inside the polar scope! Once I had removed the polarscope from the mount I discovered that the thread inside the mount that the polar scope screws into is full of what I can only describe as MUD! There is some on the polar scope tube (not the optics) too. Should I clean all of that mud from inside the thread out?? How did it get there in the first place?! If I remove the mud with a bottle brush should I then grease the inside with some sort of bike/mechanics grease? Thanks Link to comment Share on other sites More sharing options...
Brantuk Posted January 17, 2013 Share Posted January 17, 2013 It looks more like the chinese gunk they lubricate these mounts with felix - unless you are positive it's mud - I'm sure you'll be able to tell just by finger feel. This is why some folks totally strip their HEQ5's or NEQ6's down and regrease. Never done it myself though .... yet lol. It's brown in colour and hardens up in the cold.

catman161 Posted January 17, 2013 Author Share Posted January 17, 2013 Nice one thanks Kim. I may remove it and re-grease as its annoying knowing it's there now! What would be a good grease to use? I presume one that can withstand cold temperatures? Link to comment Share on other sites More sharing options...
Brantuk Posted January 17, 2013 Share Posted January 17, 2013 I'd go for silicon or lithium grease which has similar properties - heat and cold resistant - good in moist conditions - protects and lubricates etc. I think the Chinese use takeaway cooking oil or something similar lol Link to comment Share on other sites More sharing options...
+Graham Posted January 18, 2013 Share Posted January 18, 2013 Certainly looks like the crap grease they use, might even have a bit of sand from the casting mixed in. I use white lithium grease with a touch of 3 in 1 oil mixed in. Much better and you will certainly notice the difference in your mount. Link to comment Share on other sites More sharing options...

Brantuk Posted January 18, 2013 Share Posted January 18, 2013 Hmmm... regreasing a mount and getting a buzz at the same time appeals to me lol Link to comment Share on other sites More sharing options...
catman161 Posted January 18, 2013 Author Share Posted January 18, 2013 Ooh I don't think I have the confidence to strip it down Phil. I just don't like the idea of that gunk where the polar scope screws in! Link to comment Share on other sites More sharing options...
BAZ Posted January 18, 2013 Share Posted January 18, 2013 If you go to a push bike shop, they sell performance grease, I forget what it's called, but it should be white. I have a small tub of the stuff, and will get a small pot over to you if you can wait. Link to comment Share on other sites More sharing options...
+Graham Posted January 18, 2013 Share Posted January 18, 2013 Felix what you have to think about is all that crap came from inside your mount. It is in the bearings and needs to come out. Mounts are not as complicated as you might assume. If you want I can talk you through it step by step via pms. Astrobaby do a brilliant video series on doing this. Bite the bullet and get it done it will save you a lot of grief in the long run and your mount will love you for it. Link to comment Share on other sites More sharing options...
catman161 Posted January 18, 2013 Author Share Posted January 18, 2013 Hmmmm I am still very scared of doing that! I might take a look t the videos and see how I feel then maybe drop you a pm if I am feeling brave! Link to comment Share on other sites More sharing options...

Thanks for the offer of the grease but I will Si a but more research into mount stripping before I actually go for it! Link to comment Share on other sites More sharing options...
catman161 Posted January 19, 2013 Author Share Posted January 19, 2013 Cool thanks Pat. I think I may pay someone to strip the mount an clean/regrease for me as I have had a read and I do not have the tools or the skills to undertake the task myself!!

Felix I will quite happily do it for you for nothing if you want. It will probably cost a small fortune in postage though. Link to comment Share on other sites More sharing options...
catman161 Posted January 21, 2013 Author Share Posted January 21, 2013 Hi graham, thanks for the offer. I may take you up on it at some point if I have any problems with the mount but at present it seems to be working fine. Very kind of you to offer but I think I'll hold off for a bit. If I have any problems you'll be the first I speak to cheers Link to comment Share on other sites More sharing options...
