too much grease? never heard that one

Hyster trucks have a little lip on the rear axle that if you don't get it over it well chew the bearings and axle up.

hi guys
the steer axle set up in this truck is too light for 3 ton useage. hyster advise more frequent inspection required. but they say that on most of there common failures

I tend to see more bearing failures on cushion tire trucks.
The 'suspension' provided by the pnuematic tires saves the bearings from much of the shock-loading.

There are many installation problems that can cause premature bearing failure;
too loose
too tight
spindle damage
not enough grease
too much grease
wrong grease
etc...

I believe in installing the bearings a little on the tight side. My logic being that the wheels never do more than about 20-30 rpm, so heat is not much of a factor, and it will help prevent brinelling by distributing the load around the entire race.

I have better luck with moly-h lube as opposed to ep2.

When you examine the failed bearings, what do you see? Is the grease burnt? (ie. stinky) Race failure or roller?
