CB360 Swing Arm Collar Problem
cbxman:
--- Quote from: Oddjob on December 08, 2023, 02:38:40 PM ---My CB1300 has 2 ball bearings on the O/S but a long needle roller on the N/S, possibly because it will withstand the pull of the drive chain better.. Oddly enough it's not the bearing that starts to fail but the tophat bush that runs inside the needle roller. Due to lack of assembly grease no doubt, mine got an advisory on it's first MOT for swinging arm play.

Ken,
Thanks for the heads-up. My CB1300 A5 has only done 20k but I'll check the S/A when I have it up on the Abba Stand (no centre stand on mine wtf!)
I guess the CBX was one of the first bikes to exceed 100hp, so I guess they figured it needed to be beefed up. the 1300 is real grunt bucket, where's my grease gun!
Cheers,
Jerry

Trouble is Jerry is that the 1300 has no greasing point for the swinging arm bearings, if they don't get enough on assembly by Honda they wear out quite quickly, mine had done about 25K when it got the advisory, TBH I thought they were taking the piss and looking for work but when I checked they were right, definite click when pulled side to side, I didn't have the parts to fix it then so I thought I'd check the torque pressure on the bolt, should have been around 63ftlbs IIRC and it was still that, in the end I cranked that bolt up to 125ftlbs before the play went. I bought a spare swinging arm and a complete setup including a new bolt, just in case, I did a complete write up on how to change the bearings on the 1300 forum, including how to get around the special tool requirements, I had the special tools and it's easier with them but doable without. I also drilled and tapped the swinging arm to take a central grease nipple the same as you've done yours. It works fine except the pressure tends to push out the bearing seal on the O/S and you need to push it back in afterwards. No trouble with the bearings ever since, the location of the grease nipple though is difficult to place, mines on the top and is just reachable from around the rear master cylinder area.
Main stands are available on Ebay every now and then, you need the earlier version which has a bracket sticking off it for the rebound rubber, the later version (08 onwards) don't have that bracket. I also fitted a grease nipple to mine, using the welded nut method. Works a treat but again position of nipple critical, got mine wrong and it hits the expansion chamber for the radiator, so I fit the nipple when I need to grease the stand and remove it afterwards
This is the later version, no bracket sticking off it.

This is the one you need, note the small bracket with the bump stop fitted.

Ken,
Thank you for the links. I was getting excited until I saw the shipping from Japan...Ha Ha!
If you spot another one please let me know.
Cheers,
Jerry
Bryanj:
I remeber when Honda did the pro link rear end and they needed completely re bushing/bearing for first mot
Oddjob:
The Japanese one seems to be missing some parts, both of the springs, the pivot pin and the locking bolt mainly.
I do have a spare stand, it was fitted to my 09 bike from new, the problem was the dealer ordered the 03-07 version and the bump stop bracket hits the later style exhaust so they cut part of it off with a hacksaw, that left part of the bracket still attached. When I fitted an Akrapovic exhaust system I needed the earlier type so bought another and had it powder coated before swapping them over. All the first stand needs is a small plate welding onto the existing plate and it good to use.
