Thread: EP00 Greases for front wheel hubs.....

Actually Andy, i mixed ep90 with molybdenum disulfide or lmm and half a dose of oneshot in the front hubs of my s2a. Never had a problem. U joints and railco were good. I also had freewheeling hubs which i hardly ever locked up. Cheers Rod

Maybe this alternative: SEMI FLUID GREASE | Penrite Oil

Its actually the sort of EP00 / NLGI 00 that I am talking about - its a 00 and has no moly.

Interesting the timkin OK load is 18kg for this product, which I think is low - I've seen better on paper for other 00's and I think one shot is 23 or thereabouts?

Can’t quite remember what I mixed up in the past, but thinking it was moly based with 80/90 mixed in. Think still have some mixed actually.

There are numerous products on ebay packed in the correct squeeze sachets which would most probably include the moly.

First a disclaimer - I am not a grease expert but have had to select oils/ grease for a few particular applications when I first got out of uni (30ish years ago). If you want a reference on grease/oil selection, then the first 40 or so pages of an old SKF bearing catalog is second to none.

I may not have read the OP correctly and be off track but NLGI is about the viscosity or hardness of the grease. So every grease would have a NLGI designation.

Greases have wax in them and this makes them a bit like silly putty, if you hit silly putty hard enough, ie with a hammer, it will fracture like glass, instead of squashing as you would expect it to, you can also do this with pitch if you can get your hands on it. The colder the temp gets then the easier this happens. If you have a bearing running at high speed, this may happen when the ball in the race "hits" the grease, if it's too fast for the grease it will fracture in-front of the bearing and "fly" away instead of lubricating. Oils will do the same thing but you have to hit them a lot faster. So you would typically use a low viscosity grease where you had a high speed bearing that really needed an oil but you couldn't / didn't want to use oil. Remember that high speed in this case is not the speed of the wheel but the speed of the ball in the bearing race. So the grease would be selected for the largest diameter bearing running at the highest RPM in the coldest conditions. So some nutter in Scotland, running 235 x 65s on 15 inch rims down the hi way in winter.

From memory Moly doesn't do anything when the grease is working properly, but it does provide a thin film to protect the surfaces for a short period of time if the grease fails, as above or there is not enough grease to go around.

In the case of a wheel bearing, when you jump in your car on a cold morning and instantly burst onto the hi way, the moly will protect the bearing for a short period of time while the lack of lubrication causes the wheel hub to heat up enough for the grease to start working. So while you will be able to use a higher viscosity grease with no moly in Brisbane you probably won't get away with it in Oslo.

In answer to the original question as to mixing LMM with oil, as long as the oil doesn't have an additive that makes the grease separate and it mixes homogeneously, ie you get a thin grease rather than tiny lumps of wax in oil then there is no reason it wouldn't work.

Yes, I know :-) Thats not actually where I am coming from though. Let me explain further:

I went down this rabbit hole as I can buy a 20L EP 00 drum for $8.50 per litre - compared to the .350 ml one shot packs - which sell for about $66 per litre as a comparison. IM not looking to buy little packs of 'one shot'- i'm more interested in someone chiming in about extreme pressure '00' greases -with/ without moly as per my OP.

I had a 20l EP 00 grease from a wholesaler, only to discover it did not have moly in it - so I'm more interested in knowing about EP 00 greases and their suitabililty in hubs/ CV's - if the Moly is absent.

Cheers though Philip.

I'm leaning this way. cheers Rod.
