Final drive about to fall off.
- Thread starter Steptoe
- Start date
The Motorworks version..
I went through 2 sets of those on my GSA, first pair were grooved and scored after 6k miles and the replacement set maybe just a little more.
Tight tolerances and wouldn't accept any grease.
OEM are definitely the better choice but give them fresh grease now and again...maybe something like Aeroshell 14
Actually, after yet another look..I'm wrong !
Just use Aeroshell on OEM and all will be good.

Yes as Ian J pointed out, these are the Emerald Island ones.
I have them on my bike and they work very well - been on about ten years.
I do grease mine.

Mmmm, well i have just pit a set in an 1100GS and because i inadvertantly ordered the wrong set, also have a set to go in to an 1150GS.
Which brand / from where they come, i dont know.
I have used ThioGrease in mine.
Will see how they go.
Have added greaseing them to the same schedule as oil changes.

Or Nushings. Cheap, and they work.
Just seen this post. Very interesting.
I fitted the 'alternative' bushings from Motorworks on my 1150 and yes, they came with grease nipples.
Whilst I'm still not a fan of the nushings - though I should say, the versions shown in Ian's post above look noting like the items from the US I'm familiar with) they would seem to avoid this business with seizing when neglected...
So they moral of this story is, don't neglected. Maintain and service
ps. Steppers, you've really fucked up that swingarm

The picture I posted was not of the “nushings”, it was a picture of the bushes which were probably fitted which failed on the subject bike.Just seen this post. Very interesting.

Ah! Ok. I think it was the black component that had me thinking they were another version of the nushingsThe picture I posted was not of the “nushings”, it was a picture of the bushes which were probably fitted which failed on the subject bike.

What's wrong with Nushings - had them in my 1100 for years and thousands of miles, plenty on gravel and they've been fine.Just seen this post. Very interesting.

Me too, on my 1150...
Here we go, digging up an old story (but new to you maybe).
Me, personally, from a mechanical perspective, does not think plastic (Nylatron) in this particularly scenario/location is a great idea. I'm am very familiar with Nylatron that the nushings are made with and know it's properties quite well. It's actually a really good material. But this location, with the forces involved, it is my position that this joint should be restrained to one axis of movement only. Nushings cannot offer that, so we are left guessing what the knock on effect that has. I get it that they mostly work, but I'd bet there are scenarios they don't.
Yea, Steptoe's post demonstrates what happens when you do sweet fa in terms of maintenance (though noted it could just be the bike is/has been left standing...and neglected). But that's not unique to the (metal/bronze) bushes, the same happens the they OEM bearings, as it does and it's documented in here.

Is there anyone with real experience of problems with Nushings I wonder, and ones that have been fitted carefully and correctly. I have just fitted a set to my 1100GS and I had a set in my old R1150RT. I understand that there is plenty of theory and discussion on bike forums about technical things; lawd help us on US sites like ADVrider when the engineers start bickering, but I'm big on actual experience which as biking is more and more talk than walk in many instances, is important.
The standard set up has always been a fussy and expensive fiddle with two undersized bearings doing all the work, and thats totally in practice, so lets have the same about the alternatives...

"...two undersized bearings..." And Nylatron is supposed to supercede those? My point precisely. Especially if you're thinking the OEM are too small (which I doubt) the nushings have to fit into the same space...
I must stress that I get that they're out there working. It's just that I think they're 'working' within parameters. They won't cope with 'everything' nor is it clear where the loads are transferred to, as the nushings flex, which they will (compared to metal bearings/bushes).
I've had the discussions and there are other ideas out there. Each to his own

Dunno, riding two up fully loaded on thousands of KMs of gravel in Africa and South America and mine are fine. I would imagine most problems are due to incorrect fitting.
I was thinking more on this last night and I reckon at lower speeds, there's probably less of what I'm describing as an 'issue', but at higher speeds (motorway speeds) especially with luggage and the sack of potatoes behind you, I do imagine it flexing, which can't be entirely a good thing.
But at least it won't seize up if neglected

Yep, I get and have read the theories but there a ton of sets of nushings out there and I am wonder where the stories and evidence of practical failures are, not including making and arse of the fairly simple fitting regime...
Well, this has just happened to me (the pivot pin failing).
I was entering a village yesterday which had a 20 mph speed limit. What a godsend - as I entered the village the rear end suddenly went wobbly.
Thought I had a puncture at first, but after getting the bike on the centre stand I could move the wheel side to side by a number of inches. It became obvious that something had failed at the paralever pivot.
I've just pulled it apart and discovered the failed pivot pin.
The bike (R1150GS) has Nushings fitted which are sill intact and in good condition (~10,000 miles). I can't see a reason that these have contributed to the failure. The bike has 70,000 miles for what it's worth.
I plan to replace both pins with OE but would like to understand why they failed. A Google suggests this failure isn't common place. If the failure had happened at speed I might not be typing this....

Can't be sure without a much closer look, but it looks like a machining failure.
There should be a radius where the diameter changes to relieve any stress

What kind of riding has been done in the last 10k miles? Motorway, with luggage, pillion, green laneing, only road use etc etc?
