No dust covers.  I think frequent exercise may be my best bet.  Change of job coming should help in that regard.

I thought I was the only one that still runs dust covers!!  Seems like every truck I see anymore has them gone.....

I was put on this earth to do a certain amount of things....right now, I'm so far behind I could never die!

A phosphoic acid would disolve any rust and a zinc phosphate coating would prevent flash rust for several months inside the drum.

I have a phosphoric acid that leaves a zinc phosphate coating in a spray bottle. But I don't see any way to spray it inside the drum without taking the dust covers off.

Easiest way to get the Fullers Earth in the drum is with a catsup bottle. Squirt some in and drag your brakes around the yard a little.

Keven you'll never get the fullers earth applied properly on truck drums and even if you did I don't think it's going to help. Fullers earth is more like very very fine cat litter and adsorbs moisture and oils. It is also a very fine abrasive which smooths the drum so the brake doesn't grab so aggressively. Quicker to cage them and get it over with.



You hit the nail on the head Tony...put the air to the maxi's...slip the T-bolts in set the nuts and it's done, can't get any simpler.

Be careful when you follow the MASSES......sometimes the "M" is silent.

Need to figure out where to get this fullers earth stuff.  Hoping now that it is stored in a dry space it might not be as much of a problem   Can't wait till we get the doors installed.  Been on order since Jine.  Last year it took about 8 months too.

the pins on the clevis can seize also.

it also reduces the stick–slip phenomenon in hoist drum brakes in normal operation. Just a dab will do ya.

Grease or oil in them Kevin! :D   Actually, on my dragline, if I'm not gonna use it for a while, I'll pitch just a tiny bit of Fuller's Earth in the drum and smear it around with the brake before I shut it down. Seems to help. It's also good for scouring the drum when I start back up.
