grease zerks?

Is there a friggin' zerk on the rear swing arm of the 83 750E? I so cannot find it.
](*,)
I finally got the zerk on the steering stem to accept grease by drilling a tiny hole into the race that was blocking it, then proceeded to pump in 107 shots of grease without anything coming out through the bearing seals on top or the bottom:shock:
Is this not a sealed tube or does it communicate with the other tubes of the frame?
But that top bearing feels nice with new grease in it.

I know it is a sob story, :-({|=
But, back to the original question, is there a zerk on the swingarm? I would love to get rid of the annoying rubber sqeak back there too.

On a really hot day you may end up with grease dripping out of your lower bearing onto your tire, need to keep an eye on that.

I think the only time I've ever seen grease zerks on a bike were on the girder frontend on my old Ironhead Sportster, and that was just to keep the brass bushings happy.
 
My '79 GS550 has a zerk on the left side engine cover feeding grease into the clutch pushrod mechanism. Only zerk I've seen...so far.

Regarding the steering head, I think the area is open between the upper and lower bearings. You might get some grease in at the upper but the lower won't see any unless it drips down.

Yeah there's a large cavity in there. The steering stem diameter is significantly smaller than the head tube diameter (at least on my 750). You could pump grease in there for a long time before you filled that up. And, yeah, it would probably ooze out the bottom and make a mess.
 
if you swing arm is making noise, you may want to pull it and inspect the bearings, these dry out, rust and seize then break loose and chewy themselfs up. basicly these bearing go bad pretty easily.
 
The 83 GS750E & ES had no zerk grease fittings on them when stock. If your steering head or swing arm are not moving properly the a disassembly, cleaning and inspection is the only reasonable fix.
 
The bushings/ bearings in the swing arm are tight, the squeak is entirely the rubber bushings on everything down there. I was in there with lube one day spraying everything I could see, catching all the run off on some newspaper under the bike. I managed to get rid of about half of the noise, but there are a few more bushings I apparently didn't get to. It is :oops: embarrassing to stop at a light and shift my weight and have the bike squeak like a mouse being killed. Not worried about the grease dripping out, high temp moly doesn't turn to water like some others, just wondering if the head tube was a contained vessel or if the down tubes of the frame had an opening in there. I guess I will shoot some more in there until I get some ugly black crap coming out of the seals. Everything feels fine and works well, just more limber now with some lube.
 
the only rubber bushing bach there are the ones the shocks use on the shock eyes and the clevis mount. Every thing elese back there is metal includeing the swing arm bearings and metal bushing that fit inside it. all i am saying is the swing arm bearings going dry is pretty common with these bikes and should be checked every so offten and when you do repack them with grease real good.
 
Clone, I just did the exact same job a few months back on a 1984 GS750 E.
I also had a bit of a squeek coming from somewhere in the rear suspension linkage.

Best way to work this out is take everything apart, clean and repack with some fresh grease. I think I used some wheel bearing or constant velocity joint grease to do the job.
Up front, I pulled the forks and triple clamps off. On the rear I pulled the rear shock and all the linkage assembly out as a unit and dissasembled on the work bench. Then I pulled the swing arm off and greased up the needle bearings.
Both front and rear bearings were pretty much bone dry. Not all that dirty (that was a good thing) but not very well lubed either.
Reassembled all with fresh grease and no more squeek and all the linkages are perfect. I did luck out as I thought there would be some nasty wear and tear in the bearings, but all was in very good shape.
There will be no zerk fittings to be found anywhere on the swingarm. The frame area where the triple clamp shaft fits through is completely hollow.
