Default Any lift truck mechanics on board?

This is kind of boat related, we use the lift truck to move the boat. Is OK right?

We are just finishing up a brake job on our 9000lb Mitsubishi & I have a question about adjusting the wheel bearings. In my experience (which is limited to regular automotive and trailer stuff) the bearings are tightened (by hand) to seat them, spin the wheel a few times, tighten again and then back off to zero pre-load or slightly further as needed to align cotter pin(or other lock device).

Is this the same with the larger full-float axles or do the bearings actually get some pre-load?

Full floating axles can be set the same way, however there will be a torque figure probably in inch pounds that would be exact. Try call your brake pad supplier.

Witha heavy drum like that it's important to torque to about 50ft/lbs while rotating, then back it off and set as you describe. This centers and seats the bearings. This is true for just about any kind

Marc,

We're a Toyota forklift dealer, but, I do have
a repair manual that covers certain Mitsubishi
forklifts ranging from 2000-8000# capacity.


It says to tighten the nut to 101 ft/lbs, back the
nut off 80* rotate the drum and check the preload....preload
is 4.7-7.6 ft/lbs.

I would think your unit should be close to what this requires.

That is great, kind of what I expected. I'll go with that.

BIG THANKS to both of you!!
