Hi,recently been to the Manx on the GT 535.
Had some indifferent weather. When I wheeled it in the garage without the engine running, whilst sitting on it, there is a squeek/squeek coming from the swing arm pivot area. I can't see a grease nipple anywhere. Does anyone know if there is one or any other way of greasing it without stripping the whole rear end off?
Also, does anyone know what kind of bushes the swing arm has please? Dave

I don't know about the CGT, but the B5 and C5 like mine have plastic s/arm bearings that are prone to early failure. Our host does a silent bloc conversion. You can't grease the plastic ones as far as I know.

Thanks for the reply buddy

Having checked this out with our hosts, it seems there are two needle rollers and several spacers and seals but odly only one plastic bush on the left side.....why only one??? Only on an Enfield I guess😮

Not too unusual, I recently removed the swinging arm from one of my other bikes in order to re-grease the bearings. It has two
needle rollers on the drive side and one on the other yet has sufficient room to fit two! It's been reassembled with four
I removed the swinging arm over the weekend and checked the nylon bushes on my B5 but could find no discernible play. probably good for another couple of years yet!

Hi guys------- I was under the impression that in general Engineering terms needle rollers were not a good idea for a bearing that didn't complete 360 degrees of rotation in service......Classic example being a con-rod with a plain journal bearing at the small end and a roller bearing at the big end........For a temporary "fix" with the squeaky nylon bushes try a silicon spray ??

I thought the silent blocks on my old 350 were a bit crude at first but they havent cause a nanosecond of trouble in coming up for ten years now so Im a convert. Id never want to have to get them out mind.

Hi Guys----
the trick when fitting Silentbloc bushes is to make sure that the semi-rotating part ( in this case our rear swing arms ) are final-fitted in such a way that the bush itself is in a "Neutral" state with regards to torson...ie}--- no pre-load...
