Greetings fellow GMC'ers
I'm concerned I've not been properly lubricating my bogies... None of my myriad of manuals have specific information on how to do this
My question:
What is the proper method to grease the bogies at the back of the coach?
I understand there are kits you can purchase to make this process easier, but how was this maintenance originally taken care of? If possible, I'd like to be able to grease them properly without buying additional tools, etc.
I do have a grease gun, and been using it for the pins facing outward.
Thanks ahead of time for your feedback, and happy trails!

Hi Mango,
When we grease our rear bogies, we use a floor jack to raise the bogie to the point just before the wheels leave the ground. Then feed the grease in and watch at the inboard area (right where the wheel well liner meets the frame) to see the old grease move. Usually it's two or four pumps on the gun. We do this after every trip along with an oil change. Hope that helps!

Same here. Watch for that grease to come out the back. Sometimes I use a flashlight to see the rear, depends on how the sun is shining.

well hells bells, I've put 4k miles on my coach since I took ownership, and never did that as of yet. guess that means I need to get a grease gun and get to pump'n'...

if you jack up under the top hat and then let the air out of the bag you can put a small hyd. jack under the bogie arm where the spindle attaches and lift the wheel off the ground.
now you can push and pull on the wheel to see how much play you have in the pins and bushings. worth doing if you haven't checked this yet.
i suspect that much of the poor handling of the coach is due to pin/bushing wear on the center wheel.

the top hat is the big casting that the bogie arms are attached to. this is where you would place a floor jack or use one of the bottle jack hooks if you have one. if you don't then you need to get one.

That's a new nomenclature for me, Fred. The only part of the rear
suspension I've ever heard referred to as "top hat" is the flanged bushing
on the outer end of each pin. That bushing, which is intended to control
the axial play in the suspension arm, does indeed look like a top hat in
profile.
I think the term "bogie" is more commonly used to refer to the casting to
which the suspension arms are mounted. The GMC name for it is "mounting
bracket". I guess that seems a little too generic a term for it to have
found general acceptance.
The term "bogie" is itself somewhat misleading. As a railroad expert like
you well knows, it generally refers to a complete set of 4-6 wheels and
suspension members under one end of a railroad car. Yet I've never heard
anyone use "bogie" to refer to a complete suspension assembly.
Sorta like the front rear, or rear rear, or front back wheels. :-)

The note was too long already. Since the aircraft nomenclature was adopted
from the railroad application, I thought it could implied.
Now as for the other military flying application, I'll be darned if I know
how unknown aircraft became known as "bogies". I sure "shot" at a lot of
them though, back when I was a Radar Intercept Officer (RO) in F-89J's and
F-101B's.

You could be right, Emery. But us southerners wouldn't know 'bout that
cause we only knew about the boogerman! In fact, we even had a rough
neighborhood known as boogerville.
Bogey (sing.) Unknown aircraft
Bogies (pl.) Multiple unknown aircraft
Bogie (sing.) Wheel assembly
Bogies (pl.) Multiple wheel assemblies
???
They tell me the ambiguity of English is one of its strengths. :-(
