CB360 Swing Arm Collar Problem
Johnny4428:
I agree Jerry, we don’t spend thousands of pounds on these machines to splatter them in salt and watch them rust and corrode in front of our eyes.

Before I fly home tomorrow can you measure the oe collar and the Tourmax version and post the lengths please

Hello Ken,
As requested.
The overall length of both assemblies is similar. The Tourmax being about 1mm shorter. I guess the frame will flex to cover that when the through-bolt is tightened. The rebated section passes through the end bearing to contact the frame.
Cheers,
Jerry

Hi Folks,
Just to finish this thread.....
The OE swing arm collar is not available in the UK, so I would bite the bullet and install the Tourmax Upgrade kit.
Given that this kit has no obvious weather seals, (the OE seals are discarded) I decided to drill the S/A in the centre nearest the lower pressing weld line. I tapped the hole to M6-1 and screwed in a 90º grease nipple. With two aluminium washers, I could tighten the nipple to point where it was easy to connect my grease gun (slight to the r/h side of the tyre from underneath)
Whilst the S/A was still on the bench, I pumped CVJ Moly grease through the nipple until it squished out of the two needle bearings. I then added the two end bearings and installed the S/S in the frame torqued down to the FSM value. I then pumped more grease in until it came though the end bearings. I figured that CVJ grease is very sticky and water resistant and very strong under compression and ideal for this job.
The finished job is excellent. The S/A has no slop and swings up/down with no effort at all.
If I ever get caught in the rain, then a pump of grease will expel any moisture, if any at all. CVJ grease is never likely wear out...especially when you consider its intended use.
Things to note. If you assemble the needle bearings on the shaft, you can feel a small bit of slop which was a little worrying, but whilst I was researching needle bearings, I discovered that they will always be slightly sloppy because they must be installed in the correct size tube which forces them down to the operational size. This is so. No measurable side play at all at the wheel end of the S/A.
This Upgrade Kit is suitable for the CB450K, CB350F and CB250G5/6, CB500T as well the CJ variants (according to their website). I ordered from motorcycleproducts.co.uk
