Grease is the word

(1/5) > >>

MrDavo:
I just tried to grease my swinging arm bearings. Despite a lot of back pressure, and much grease oozing out all over around the nipple, I didn't see any grease come out around the swinging arm / frame joint.

I wonder if the little balls in the grease nipples could be seized, if there's a blockage, or indeed if some grease has gone where intended and I shouldn't worry about it? There is no play in the swinging arm, and the bike probably had new bearings, as everything else seems to have been replaced, and zero miles run, before the bike's disastrous post rebuild engine problems (see the 'Oil Pressure' thread in the CB750 forum) came to light. Hopefully they greased the parts when the bike was restored but there's no way of checking other than disassembly, which I don't want to do now she is running.

And yes, I know I should have thought of this while the engine was out.  >:(

Green1:
You should pump grease in until it oozes out and re-grease every thousand miles or so.
If you think a nipple is stuck up just swap it its not like there a lot of money.

Bryanj:
The grease nipples are a knock in type not screw in and an odd size only used by Honda, you can tap a thread in the bolt and fit normal nipples if you are not anal about originality.
If you fit Honda ones DO NOT hit on the end or you will not get any grease through them, only hit on the flange with a hollow drift---T shirt available

MrDavo:
It doesn't sound that simple to replace them after all.

I have been poking my nipple balls  ::) with a stout wire from my carb cleaning kit. One moved freely, the other one does now.

It may be my technique, it may be my grease gun isn't a good fit, but a lot went everywhere rather than in the bearing. Maybe because its tight then not a lot goes in.

Bryanj:
Sounds like the nipples are damaged to me, try a different grease gun and hold it on tight. I have a spare bolt and would modify it to screw in ones for you on an exchange basis then all you have to do is undo the nut and push one bolt out with the other, OK the nut would be on the other side but you have to be nit picky to pick that up.

You need to grease these every 1000 miles MINIMUM as the collar wears more than the bushes and is damned expensive to replace
