Massey 65 Front Hubs

Question:
This is for a 1964 Massey 65 Utility model, UNDM serial number prefix.
When packing the front hubs with grease after a bearing change, how full do you pack them?
3/4 or so?

What is the preferred wheel bearing grease?
Plain old wheel bearing grease by the tub?
There's a lot of room in there.

Thanks again
 
Not a scientific way but I pack all I can into the bearings themselves then put a gob I can put on 3 fingers between the two bearings. If the bearing starts to get the least bit warm it will flow to the bearings. These are not like a car that goes 70 MPH. I use regular wheel bearing grease and have never had a problem. IMO
 
Thank you Phil.
I pack the bearings full as well.
I had in mind to pretty well load the recesses in the hub itself with what I could get in there to suit myself and thought 3/4 full would be a worthy goal. I didn't know how much is too much for slow speed hub like that.
It shouldn't get past warm I would think.
 
The grease you put between the bearings in void does nothing. All you need is pack
bearing good even on a car that goes 100 mph.If bearing does get hot it's to late. It
will not get hot enough to melt grease so it will run into bearing. I use bearing
grease in tub that's for disk brakes.Good gun grease will work on tractors if that's
all you have. Be sure the back seal is good to keep water out. Water is the main
reason bearings goes out on a tractor.
 
Ha.
I sure cleaned a lot of old grease out of the hub from the void. Buildup over the years I suppose, and it was A LOT OF GREASE.
The rear seal is whats giving me a problem now, finding one that is. We shall see tomorrow when parts come in if they are the right ones or not. I got a box of old bearings and seals to take and compare to the order. The seals were the question mark.

Of course, that was before it was properly identified as an industrial model with help from here. Bearing numbers matched to 85/88 model, so we shall see about the seals. Keeping my fingers crossed they match.
 
Hi all,
This raises an interesting question, which way round do you fit the seals? Normally the seals would be fitted with the garter spring inwards towards the grease. MF in the UK at least recommend that the garter spring is fitted on the outside away from the grease. The thinking apparently is that it is preferable to be able to pump some grease out past the seal lip and make it more difficult for water, dust and fine debris to enter the hub. What is the thinking from your side of the pond?

Personally I have never heard of such a thing.
It would seem far easier for the garter to get damaged and go sproinging away due to grass and debris. The seal I removed fron the tractor did not have a garter spring, it was just a hard rubber lipped thing with the recess where a garter could go turned to the inside, smooth side out. It has a slightly rounded profile to where it would not fit flat against the sealing surface on the spindle, at least on this tractor.
 
There is hundreds if thousands of seal profiles. You could put the seals (with or without springs) in backwards, but you still need some sort of dirt/dust seal on the outside for obvious reasons. Ferguson/MF front hub cap with a grease zerk.

If I could fond one that would fit at a bearing supply house I would get a double lip seal so both sides would seal, one to keep grease in and one to keep dirt out. It should be available.
 
Eh, put me in with the group that thinks it's not a huge deal. These are low speed machines, unless you've got a loader on the front you'll probably never overheat a bearing unless it's run dry.

The way I look at it is, I doubt the bearings on my '64 have ever been serviced. I'm going to pull it all apart this spring/summer to repack and such. I've got one that's a bit loose, and I've got a loader on mine which loads up the front axle a lot depending on what I'm doing. It hasn't failed yet, and probably won't in my lifetime either.

ptfarmer- do those greasezerk caps actually work? Or do they fill that entire void between the bearings with grease? For as little service as the front bearings need (unless this is a high usage, daily machine), I'd think that simply repacking every few years would be plenty, no? (I do like the idea of hose, though)
 
It kind of works the same way as "bearing buddy" does on trailer axles, and it does fill the entire cavity with grease. It is good for if the hub goes underwater, it will help keep any water out. I have run across wheel bearings where only they were packed, but the spindle is rusty, and made the inner bearing at times difficult to remove. Grease is cheap, and personally I just don't like the idea of having all that empty space with just the bearings having grease (I've never had any bearing failures from too much grease).

Gotcha, you make great points. I just might pick a couple of them up. Thanks for the clarification.
