Clay based grease for slack adjuster/cam shaft??

[AKBrick]

Okay, I know that's it's been a little while since the last post on this thread. Today I was in the Harrisburg, OR. Monaco Service Center store and lo and behold, there were three tubes of clay-based grease sitting there in a bin. I bought one for seventeen bucks which should last me for quite a long time. I had actually forgotten that I've been looking for this grease and I havn't been close to any company lube stores like Shell or Exxon so I didn't buy any. CheetahGirl and I were there to kill some time and see if there were any Safari Logo shirts to spend some money on. I was walking out the door when something made me turn around. There they were all by their lonesome, just waiting for me to see them. In retrospect, maybe I should have bought them all. Anyway there are two left if any of you are hanging out there with a 2006 or earlier Roadmaster chassis.

So finally, this weekend I will grease my slack adjuster/cams on my air brakes with the correct grease without mixing clay-based with lithium soap-based grease.

I did talk to my service rep in Coburg, OR. and he said that they were using the newer lithium soap-based greases on top of the old clay-based greases with no problems. Hmmmm...we'll wait and see how that goes for people in the future.

Happy travels,

Wowee,thanks AKBrick for the post. I'll try to buy a tube on line for my '06 Monaco Knight. Maybe they still have some clay based remaining.
Again, thanks, now if I could just do something about this short engine burp tube. Doc USAF

William,
Some say grease both fittings on the U joint, some say no if new grease comes out of all 4 bearing caps. I don't grease both. Both zerks channels end up at the middle of the U joint. I just make sure new grease comes out of all 4 bearing caps. Sometimes the joint may be in a bind and a particular bearing may not take grease. Moving the coach a couple of feet usually solves the problem.
I don't think there is a universal standard color for various greases. I think you are ok as long as the grease you purchase has the certification Monaco requires or exceeds it. Some mechanics say Lithium soap based grease with Moly holds up better under the pressures in U joints than standard lithium soap based grease.

McMaster-Carr has a pretty good explanation of the various Lithium greases.

under find products type in grease and there are several pages explaining the various types of greases.

Yay, finally, I finished my chassis greasing project this morning. That gives me the satisfaction of saving a hundred bones.

Before you get under ANY machine, support it with adequate jackstands.

You got that right Dan. Even with the jack stands I set the jacks down to just touching the concrete. I get a more than a little nervous with 30k lbs above me. I also have my mobile phone with me. I know it's overkillbut I'd rather be laughed at than cried about.

Yesterday I went back to the Harrisberg Service Center store and there were still two clay-based grease tubes left. Now there is just ONE. I bought another one just to have it. Ya better go and snatch it up if you want it!

I'm ready to lube the chassis for at least four years now. Maybe THEN CheetahGirl will let me buy a Camelot or Dynasty.

Happy trails,

Clay based grease is only required to be used on disc brake calipers as noted in the exert from the Roadmaster grease schedule below
"Quote"
"Drum brake lubrication does not require a special high-temperature,
clay-based lubricant although it can be used. A high temperature
Lithium Soap base lubricant can be used to lubricate drum brake
actuating components. All tag axles are equipped with drum brakes.
All models, unless specified in Air Disc brakes, are equipped with
pneumatic actuated drum brake systems on the front and drive axle.
Lubricate each fitting until new grease purges. Remove any excess
grease" end quote

I was able to purchase the "Clay" based grease from "Fleetpride". This is commonly used on the "Rockwell/Meritor" brake system. $17.00 per tube.
