First Time Greasing
« on: May 04, 2019, 01:01:05 AM »
Any tips for someone who's never greased a bus before?

My big question: How many tubes could I need?

I'm thinking of ordering Valvoline Synthetic Moly fortified grease online for like $6 each. I've had the bus for 4 years and its greasing history is unknown. Paid a mechanic to grease it (even gave them the map from the manual!) and upon later inspection they did a handful of zerks on the steer axle and that's it. :(

How many tubes of grease? I've read that some people shove like 15 tubes into their tag axles?!

$6 each? I buy a dozen to start. You don't want to run out in middle of job. Jack up each side of front axle before greasing kingpins. Wipe off each grease fitting with a rag before applying grease. Some will probably need dried buildup scraped away with a small screwdriver first. Mke sure great is going INTO fitting, instead of all around it. Be sure the connector on end of grease gun goes on securely. Frequently, dirt gets into the outlet ad it won't keep from leaking grease. Most ends are able to be disassembled, cleaned, and little fingers reversed if worn excessively. An outfit makes and end that securely clips on to end of fitting with a release lever to remove. I recently got one, but haven't tried it out yet.

you might want to get a air grease gun . that is what I use and when I first greased my mci the regular pump grease gun would not penetrate the old dried out grease . then I bought a cheap air grease gun and after I used it on the nipples a few times I could go back to the pump gun

All good advise.

HUGE support for proudly buying a powered grease gun, pneumatic or cordless, whatever your budget will withstand.

Nobody greases properly when they get tired...

Ditto on putting a longer hose on it, right there in the store where the grease guns are, there are proper high pressure extension hoses and couplers. It is not uncommon to have to stretch your arm way into there, and there's no room for the gun. Again, the more contortions, the more fatigue, the sooner your greasing standards start slipping...

Check the tag axles, they often have a different larger fitting, you'll need to source one of those from an industrial supplier, civilian sources won't know what it is. Remove the fitting and take it with you to get the match.

Buy LOTS of grease, you'll use it next time, and store it properly, if you didn't know, tubes standing up, with the sealed end down, plastic cap end up. Lying on their side, they start leaking out and make a mess.

And it isn't a bad thing if it takes two days... there is a lot of time and physicality to get the bus into the air, and then all this crawling around and stretching and pushing, then the bus is still in the air and all that stuff has to be gathered up and put away... fatigue makes mistakes... going back fresh tomorrow isn't a bad thing... or the day after that...

happy coaching!

If you use a powered grease gun, be aware that there are certain fittings which still need to be done with a hand-pumped gun (or with extreme caution). On my bus things like the speedo drive on the transmission and a few remote zerk fittings all have to be done by hand. The remote fittings especially - I found a huge mound of grease under the end of one where the remote extension tube had ruptured. I'm guessing there was a restriction in the flow where the extension tube connected to the original zerk location, and the powered gun just kept pushing the grease through.

And don't buy the zerts/zerks/fittings at the cheapy store, they don't go into anything, threads are crap, rust badly very soon...

These aren't a place to save pennies, buy good ones from industrial grade supplier/name brand.

Yes, I love my Lincoln pneumatic too, if it fits the busnut budget, just do it.

Didn't think I'd be that impressed with a cordless battery powered grease gun until I got one as a present. (Milwaulkee brand) But it sure makes a chore much easier. No longer any need for a third hand. Those locking couplers look good too, That's going on the list. I don't know how the cordless gun compares to air powered for sheer pressure, probably not as good. But it's way more portable.

The locking coupler I use is a South African design that was from either Northern Tool or Gemplers with one release lever. I have not seen a 2 handle type. Sounds even better, who makes it? One thing is for sure, a locking coupler is highly desirable.

Very helpful tips!

I'm grabbing one of the Milwaukee M12 Cordless Grease Guns and adding a Lock Lube. The YouTube videos sold me on those.

I guess I'll get 20 tubes to get started.

If you are greasing regularly, it doesn't take that much grease. I do mine every time I come home from a major trip, like South, and it only takes less than 2 tubes. That's only a couple of pump strokes per fitting. Oh and I grease the drive shaft U joints more often than that. If you've seen a drive shaft fly off because of dried out U joints, you'll want to keep it greased.
