Hi Guys, looking for some information regarding how to grease my Mello Yello. I found some info @ GMC Net. just want to make sure that these are all
the points. Some mentioned it's a good idea to keep these greased up, since we going on a road trip from LA - Bend, OR. I would like to get this done
before.

Any help / input / tricks are welcome :)

This is what I found in 2 manuals ..

Wally,

X-7428?

Or is that a typo for X-7425?

Marc,

My coach has a grease fitting where the relay lever pivots on the relay bar. All together there are 14 in the front and the 4 at the bogies.

Note 1 - Get a good grease gun. I own 6 of them and two are just for the coach - pretty much. One is for marine things and so has a special grease
for those. I struggled for a long time until I settled on a Lincoln 1133 or 1134 grease gun. These are a pistol grip gun that leaves one hand free
to hold the coupler on the grease fitting and has a flexible whip so you can get it all the places it needs to get to do the job right. The other
coach grease gun is also a Lincoln, but decades old and has a straight pipe and I find that easier for greasing the bogies. I always carry that one
in the coach wrapped in rags in a plastic bag because it does bleed and that is messy. It does not bleed much anymore, but I have a 23 with no
storage that I can afford to get greasy.

Note 2 - These days the all others are all loaded with Valvoline SynPower. This is a synthetic grease with molybdenum sulfide. It is an extreme
pressure lubricant and I have proven its value in my own machinery. It is not cheap, but it is still cheaper than replacing parts. (No Dutch jokes
here, I'm married to one.)

Note 3 - I grease everything every 3000 miles as was recommended in original owner's manual and was typical of vehicles of the period. One thing I
try to over grease is the bogie pins. Older coaches have smaller pins that are less well lubricated, so I hit them about every 1000 miles - even if
we are on the road. It may end up longer some times, like the 1500 miles to Shawnee, I just hit them before we departed for home.

Note 4 - Do Not buy a power grease gun. (This is a lesson learned from another owner.) A powered grease gun will not let you feel the grease going in
and if it is not (there can be several reasons), you may not know until there is a critical failure.

Last Note: All ways do the complete walk around. Pull the dipstick. (Transmissions don't consume lubricant, just leak, but should be checked
regularly.) Look inside everything and check the latches and locks. Be sure everything that is there is secure and where it belongs. Then, start the
engine an listen for new noises. Coaches may not have a soul, but they will talk to you and it is very much worth your while to listen. It may be a
complaint, a warning or just saying thank you for taking care of me.

There is an old saying in my world... Watermen and their boats, they take good care of each other.

Matt,

Sorry Mate, I'm going to disagree with you on the power grease gun. I would make the following statement; if you buy a power grease
gun don't be fooled into thinking that the noise of the pneumatically powered piston means you are injecting grease; make sure you
see grease flowing out of whatever you are greasing.

I have two power grease guns from Harbor Freight and they both work well.

One of them is for Mobil 1 the other Valvoline Synpower.

Dave Lenzi supplied the hubs and knuckles on Double Trouble serviced with Mobil 1 and I followed his lead. It is easy to tell when
you've got clean fresh grease in the bearings as the color of the Mobil 1 changes from a dark to a bright red.

I have a set of Dave's hubs and knuckles to install on my new Kingsley and I'll service them with Valvoline Synpower and see if
there is a change in the color of the grease when you've got fresh grease coming out.

Something else I've noted; if you store the grease in the guns with spring pressure on it you will cause the grease to separate.
Both Mobil 1 and Valvoline Synpower do it.

I take the cartridges out, put the plastic cover that comes with the cartridge on one end and fold up some aluminum foil, wrap it
around the other end and put a rubber band around it to keep it in place.

Caution with power grease guns. A very experienced mechanic/coach owner/rebuilder injected grease into a finger with a power grease gun. Luckily he
didn't loose his hand. Many trips to a specialist MD over a year finally got all the grease out. He was going to tough it out but a friend recognized
the danger and convinced him to get medical attention. Emergency room told him no problem. Friend persisted and got him to go to a specialist.

Depending on your PO and if they did some replacement of parts you may have up front 2 more fittings than when they left the factory in Pontiac. That
would be the base of the idler arm and where the relay connects to the center link. In the back you could have 8 fittings instead of the factory 4 if
someone added boggie greasers which are supposed get the grease in the pin closer to where it is needed. Be sure your engine is running in Park when
you check the trans level or it will appear too high when it is not and if on Full line will be Under filled. Running and warm it should be at full
mark.

Hi matt, thanks so much for your info.. Went online & ordered the lincoln 1134 @
https://www.amazon.com/gp/product/B0002NYDZ8/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1

Got 3 tubes of grease, Since I have to wait for the gun to get here, I decided to get a grease gun from Harbor Frieght for $16 just to start the job
tomorrow.

Thinking about trying to get on the same plan @ 3000 & 1000 miles... Have to see how well it goes tomorrow and go from there :-/

Great tip on keeping grease gun + grease inside while on trips...

Hi Matt, thanks for all this info. As a newby and non mechanic :( I am a bit confused and worried now.

Not sure what you mean with some terms & info in your post. Could you or some1 please explain ...

Locking the air bag line at the bag, removes that piece of the rear suspension from any input or output from the air system.
Spray your air bag with soapy water and look for bubbles.
Correct rear height is measured by the top of the slot in the frame located behind the rearmost wheel. Measurement is 11 3/4 inches to the ground.
Yes, the properly set ride height has the coach sloping to the rear.

Cut a 1"x1" stick or dowel rod to the 11 3/4 or 11 7/8 (I think that is book spec) and keep it in the compartment under the drivers seat. That way you
can check height each time you do your walk around inspection.
On the transmission fliud level on GM vehicles. Drive the vehicle a couple miles, pull over and leave running in park on level surface. Open hatch and
pull and wipe trans dipstick on left side of engine. Reinsert and pull and read stick. Should be at Full Hot mark. Reinsert stick and shut off and
secure hatch if level ok. If low add Dexron through dipstick tube using long transmission funnel and recheck by above procedure. Don't add more than
1/3 qt at a time without rechecking to prevent overfilling.

SInce the Onan prevents you from reaching the rear ride height slot on the
driver's side, it's better to set the ride heights correctly using the
slots on the passenger side. Then measure the distance from the ground
beneath each slot and cut a measuring stick to that length. Personally, I
prefer a block of wood cut both two distances, like this:

I do as Ken except not near as 'purdy' as his. I just take a 1"x2" and cut it the same as his and it's small enough to fit most anywhere. I have 4"x4"
blocks cut as his for setting ride heights in the rear but leave them at home where they can be easily 'lost' in my junk and have to be replaced.

I just check right side, eyeball from the rear for level, I also compare R / L by fingers count that fit above tire to body and how tight. That
should be good for + or - an 1/8".
