How does athrust bearingwork

I'm not understanding the alignment problem you are talking about with the roller thrust bearings. This message was sent at 11:44:46 AM Sunday, January 12, 2020 Michael - California, USA Micro-Mark MicroLux 7x16 - LMS 3990 Hi-Torque Mill with power feed

It may be called a Torrington by some, but the majority of the people I know just refer to it as a "Needle Roller Thrust Washer" (or Bearing).

What grease for wheel bearings? Thread starter Hulk5T Start date Feb 4, 2021 ••• More options Who Replied?

Click to expand... It's your choice on what you have available. I use Rotella HD red or yellow cause I get it $3 a tube. Some folks like Lucas. Some like original GAA. I have buckets of valvoline red and black I use for 5th wheels and cables   Feb 4, 2021 #3 frank8003 In Memorial In Memorial 6,426 4,985 113 Location Ft.

Myself EP red tacky stuff sorry TM.   Feb 4, 2021 #5 G744 Well-known member Steel Soldiers Supporter 1,726 3,889 113 Location Hidden Valley, Az Any good grease but moly. It turns to mush when mixed with even a tiny bit of gear oil, and I guarantee oil will leak a bit. DDG   Feb 4, 2021 #6 Ajax MD Well-known member 1,569 1,415 113 Location Mayo, MD I actually researched the specifications for the milspec GAA vs. Lucas Red 'n Tacky and several other lithium based greases. The Lucas most closely matches the specifications of GAA compared to other lithium based greases in the categories of Penetration, Drop Point, Viscosity, Separation, Corrosion Protection and Water Resistance. I decided that a new tub of Lucas Red 'n Tacky was better than a 20 year old tub of GAA that has been sitting on a hot warehouse shelf.   Reactions: Guyfang, Floridianson and BKubu Feb 4, 2021 #7 C charlesmann Well-known member 700 713 93 Location Temple, Tx For those that have repacked their hubs, front and rear. How much grease, ball park, does each hub take? With ctis disabled (not working at control unit) and lines going into the axles capped and plugged, should i get a hub seal kit w/o ctis or should i even replace the seals?   Feb 4, 2021 #8 simp5782 Feo, Fuerte y Formal Supporting Vendor 12,131 9,418 113 Location Mason, TN charlesmann said: For those that have repacked their hubs, front and rear.

Leave the seals out and pack the empty space with grease. Around 3 tubes per hub between packing and filling the empty space if you clean out a majority of the old grease.   Feb 4, 2021 #9 C charlesmann Well-known member 700 713 93 Location Temple, Tx @simp5782 You mean leave the ctis seals out? There are seal kits for the 939 series for with and w/o ctis. They are sold on boyce equip. If you do mean leave the ctis seal out, wouldnt getting the kit w/o the seals be better?   Feb 4, 2021 #10 simp5782 Feo, Fuerte y Formal Supporting Vendor 12,131 9,418 113 Location Mason, TN charlesmann said: @simp5782 You mean leave the ctis seals out?

Yes. You do not need the seals for the CTIS if it is not operational. Sometimes the kits are nearly the same price for A1 and A2s. Or I find one of the other cheaper. It just depends on what I run across as to what I use. So leave them out regardless of what kit you get. Or buy the seals individually for 5 to 15$ if you search ebay.   Feb 4, 2021 #11 dmetalmiki Well-known member 5,523 2,030 113 Location London England G744 said: Any good grease but moly.

HMMM, But, Someone once told me "that gearbox is absolutely K....d", it will last about two weeks, knocking growling jumping out of second gear (1943 Ford jeep). I FILLED (packed) the gearbox with molyslip grease...And it has been fine ever since. WHEN?.........................1968!! Transfer case, Hubs, tractor joints similarly packed. Also good to date. Front and rear axles mollied. What can I say. 'Cept moly is in every truck I own, ( And every car) Engines included.   Feb 4, 2021 #12 frank8003 In Memorial In Memorial 6,426 4,985 113 Location Ft.

The down side to royco is its awful smell.   Feb 5, 2021 #14 Floridianson Well-known member Steel Soldiers Supporter 7,409 2,503 113 Location Interlachen Fl. Looking over the requirements you posted for a grease that will be applied to the outside or exposed sides of artillery is one thing. Yes it does say it can be used for other things but does not specifically say from what I read wheel bearings or that is the only grease that can be used for wheel bearings. Guess it was easer to have just one grease at the time of military service but now in civilian hands we can choose what we think best. I still prefer a EP grease used more today in wheel bearings and equipment. Here I am not worried about biodegradability, smell, color, not staining my cloths or discoloration of other surfaces. Plus mixing with other greases what we do not do on wheel bearings plus weather proof to a point or exposure to the elements. As always your truck do as you will.   Last edited: Feb 5, 2021 Feb 5, 2021 #15 Floridianson Well-known member Steel Soldiers Supporter 7,409 2,503 113 Location Interlachen Fl. I much rather see Gallagher do this test than this guy as he would make it funny. This is not meant to endorse Lucas or any other grease product for use. I will write to Gallagher and see if he will add grease to his show.

They’re wheel bearings. Just like 99% of parts on these trucks, they’re not some top secret military only magic. Any half decent wheel bearing grease will be fine. I think I used carquest brand in mine.   Reactions: dmetalmiki, Jbulach and Floridianson Feb 5, 2021 #18 sigo Lieutenant Colonel Steel Soldiers Supporter 1,704 414 83 Location Leavenworth, KS I’ve found every type of Lucas I try seeps out of my grease gun when it gets hot in the sun. GAA doesn’t. It doesn’t get much more unscientific than that, but GAA doesn’t seem to ooze liquid like all types of modern grease I try. If it ain’t broke, don’t fix it. I stick with GAA whenever possible.   Reactions: dmetalmiki Feb 6, 2021 #19 Floridianson Well-known member Steel Soldiers Supporter 7,409 2,503 113 Location Interlachen Fl. Found this read informing. Sounds like a little bleeding of a grease is not a bad thing but ability of a grease to get back to an oil state so it can lubricate correctly.

And to comment on the discussion of needing to support the cage, I've never seen a situation where the cage is supported. It simply slips on the shaft, and I always thought it just centers itself when it turn since I've never seen any wear on the cage.

I've modified dozens of them now and none have failed in over ten years. This message was sent at 3:03:00 PM Monday, January 13, 2020 Michael - California, USA Micro-Mark MicroLux 7x16 - LMS 3990 Hi-Torque Mill with power feed

The reason for my purchasing a mini lathe was to make modifications to an electro-magnetic clutch so I could replace a UHMW-PU Thrust washer which wore out every 5 years, with a Needle Roller Thrust Washer. I needed to machine a recessed section to accommodate the thicker Needle Roller Thrust washer.
