Front Wheel Grease Cups

[Baxter28]

Has anyone thought about drilling and tapping the front wheel grease cups to install a grease fitting like boat trailers have?

[ctltmp]

I have. I'm rebuilding my front end now and put the right side together yesterday afternoon. I was thinking more about somewhere near the middle of the hub that wasn't interfering with anything else.

Let's see what some others have to say. I bet someone has already done it.

Before you do that, take some measurements to see that the rim will pass over, clear the zerk when installing the rim.

Drilled, tapped, installed zerks in hubs on a 2 wheeled trailer. Had to notch the rim's inner opening a bit to clear the zerks when installing rims and tires.

I've thought about doing that, but haven't done it.

I don't get why you would need to do this, if your seals are good on the inside and the caps are tight on the outside and it has good clean grease in it why would you need to add more periodically? It will only push the seal out the inside as that is the weak link. A boat trailer is backed in the water continually, how many times does a Cub hub see water?

I've seen some with zerks in the cap before but know nothing about them. Someone was just parting out a tractor and selling them.

Can't answer the question. To many variables, everyone has different situations.

I have low water crossings and terraces which hold water. I've had the front hubs under water and often splashed with mud and water.

If your seals are good and the hubs are greased properly then no water is getting in, right? I may be the odd man out here but I don't see why a Cub hub needs a grease fitting. To me it's like the overly greased PTO grease fitting, probably more harm than good IMO.

I bought a cub that squeaked, when moving. Bone dry wheel bearings. I believe the owners manual recommends greasing, At set intervals. Easier to pump grease in, than to disassemble.

Here's a couple old threads on the subject.

Debatable.

Might not be the water getting into the bearings causing the problem, but the stuff, sand and mud, carried in the water eating away the seals and then into the bearings.

If you got water, mud, sand etc. getting in then you have a hole or a bad seal and a grease fitting on the exterior is not the solution. Time to tear it apart and fix the problem. If water, sand, mud etc. eats away the seal your gonna have to replace the seal anyway, right? A grease fitting and pumping more grease in it is just gonna come out said bad seal isn't it OR over greased will push the seal out as well, like the PTO seal if over greased?

I figure, once properly cleaned and repacked with grease, that should last you a long time. No reason to reinvent the wheel here. As Chipmaker said, if you have debris getting in, your problem is in the seal, and adding more grease can't cure that.

I had grease fittings on the front wheel caps but they didn't last long. The problem I had was when bush hogging if you rub a tree, rock or even a small sapling they are gone. You have to be very careful and not knock them off....Oh I am thinking that was my 2N....but I would have the same problem on my cub.

My thought was to put the fitting on the hub itself, between the 2 bearings. Protected by the wheel, in that location. Not "reinventing the wheel" here, just making it easier for the old coot, maintaining the tractors.
