 Topic: Good grease to use?
Posted: 03 Jul 2017 at 7:37pm |
|
Ok at the risk of asking a question with no good answer what grease do you use on your pto joints?
I have always use the old red tacky grease everywhere but I have been wondering if there is something better for my driveline. My JD 930 mower conditioner has wiped out a few joints I found out the slip clutch was not slipping and fixed that but I did notice the crosses get hotter then I would like to see. So I just figured I would ask if I should try a different grease.

I use cenex grease. It's moly, can't remember exact terminology for it. Certainly not going to proclaim it to be the best. It's what's readily available for me without driving an hour. Darrel

Been using FS blue for many yrs. Last semi had million on kingpins and still tight.Replaced front three u-joints @million just because and only slight brinnelling of crosses.(It was a turned up 425 Cat and the driveline got punished.) Figured it must be decent grease.

Most greases that contain LITHIUM would be a good grease for ball joints or u-joints. Moly greases are more for IMPACT like sockets on a dozer blade, etc... but many do use them for ball joints.

Steve I was thinking the same thing I will pick up some lithium grease. The u joints where just hotter then I would like to see makes me think the old red tacky grease is holding heat and not doing a great job in there.

Google "different types of greases and their uses." You can read it easier than I can explain it. Be aware that their are four different bases for grease. Each suits one application better than others. It's also a good idea to not mix these types.

I was told to remove ALL the old grease when changing grease type if you do not KNOW what's already in there as some greases don't 'like' each other and can allow water to get in, maybe 'thin out', etc.
Hopefully this isn't an old wive's tale,cause cleaning Ujoints is a wee bit of a PITA....
Also wipe the Zerk fitting BEFORE adding grease! One of them 'common sense' things but it'll keep a grain of sand/dirt/stone from being put INTO the bearings !

Read to your heart's content. Notice that color tells you nothing. The complex greases seem to be the better greases. Lithium +12 seems to be the best thickener, but note that there's a lot more to a grease than the thickener. http://www.machinerylubrication.com/Read/30818/determine-which-grease

I said red tacky because the grease I have always used is Red "N" tacky #2 Lucas grease. Just the name of the grease. It is a lithium grease but I was wondering if maybe it was too tacky for the u joints.

Yes I pump till I see clean grease comming out all over the place I figure grease is cheap and I don't really care if it makes a mess.

Plain and Simply....just my opinion but you just cant beat Amsoil Synthetics! There are ethanol plants around here that have switched to it and cant believe how many less bearings are going out. They buy it by the drum for their automatic greasers. I will say maybe i am bias. I grew up with my dad being a pretty small dealer and i am as well.

Synthetics are especially suited for high temperature applications. I've used AMSOIL, but I didn't like how the base lubricant separated from the thickener while it was in the grease gun. I only used it for greasing my car and I'd question how cost effective it is for an application like that.

Well how the heck do you remove the old grease? I just assumed that you would pump the new stuff in until all the old was forced out?

Yes through daily greasing you would eventually purge the grease out. The full synthetics do just that. They create less heat....less friction equals less heat.

I have a silage bagger and that machine always operates under full load and is very hard on pto universals. My Deere dealer had me try some fancy John Deere expensive grease and so far it seems to be working. Just ask your dealer for their most expensive grease they have. Tom
