Whats is the best grease that will not gunk up in cold New England winters for bearings for repacking a Yaesu G-800 rotor? _______________________________________________ ___________________________
Chris: I always use "wheel bearing" grease since its made for bearings. Same stuff mechanics supposedly use when cleaning and repacking your car wheel bearings. The pros say don't mix grease types li
OOOps, I should have qualified my answer. I was referring to thrust bearings, not the bearings inside a Yaesu rotor. Yaesu may specify the type and weight of the grease used on a rebuild. Tom, WW5L _
I use White Lithium grease. Some rotator manufacturers are using it now. For thrust bearings...It all depends. ROHN says to run theirs dry. 73 Roger (K8RI) ___________________________________________
my thrust bearing is circa 1993 and has a grease fitting and the instructions then said to grease it. tom, ww5l _______________________________________________ _______________________________________
Interesting question, though and I'd propose that the choice of lubricants may depend upon your geographic location. I live on salt water in a tropical climate. I'm not concerned about low temperatur
winters for bearings for repacking a? Yaesu G-800 rotor? You should use snowmobile grease, and not much of it. Cheers, Steve K7LXC TOWER TECH _______________________________________________ _________
A synthetic grease does not thicken up in low temps like a petroleum base does. You'll find something here:http://www.google.com/search?rlz=1C1GGGE_enUS442US443&aq=f&gcx=w&sourceid=chrome&ie=UTF-8&q=

Contact Rohn then. They run dry. If they were meant to be lubed they would have a grease fitting on them. Mike W0MU J6/W0MU November 21 - December 1 2011 CQ WW DX CW W0MU-1 CC Cluster w0mu.net ______
from Rohn that states that their TB-3 thrust bearings are to be run dry. I know that they are sold dry. I am looking for facts from Rohn that say that these bearings should not be lubricated. I am no
I just looked at the Rohn catalog page for the TB3 and TB4 and there is no note about Lubrication. This was the older Rohn catalog that Champion used to furnish. The bearings are in the accessory pag
I confess to not having read this whole thread. So at the risk of repeating others experience or making statements that conflict with real experts, let me say I have 4 TB-3's that were lubricated wit
The thrust bearing that came with my W51 TriEx tower in the early 90s came with a grease fitting installed. I've always used wheel bearing grease in my grease gun to lube it. From what I've read, mec
I also use wheel bearing grease to lube my thrust bearing. 25 years of service, no problems. Bob K6UJ _______________________________________________ _______________________________________________ T
We have some major confusion in this thread. Some are commenting on Rotor bearings, while some are commenting on thrust bearings. Different loads, different environment. Then-- the REAL difference--
It's considered both unhealthy (lots of carcinogenic chemicals) from exposure and dangerous due to explosion possibility. 73 Roger (K8RI) _______________________________________________ _____________
Amen! I had a TB-4 at the top of the tower with the big array. Now the small antennas were well above the top of the tower. The tribander (TH-5) was just above the top of the tower at 100' while the
Do what the manufacturer says ... that is a familiar statement repeated here many times. But no one has been able to find out what the manufacturer, Rohn, says until now. This should answer the quest
Taking this from a mechanical perspective, you have "steel ball bearings" running in an "Aluminum race". To begin this is not a good combination for several reasons and not just due to the difference
