Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

There's a steel bushing in place? The stocker is a composite material.

Bushings are held in place by interference/compression. If you use a hacksaw blade to cut into the bushing and remove the compression, it should slide out without too much trouble.

Yeah there's a steel "rear fork center collar" and a pair of dust seals. I'm not seeing a "bushing" I was under the impression that the pair f bronze bushings were to replace the center collar.

Page 92 of the Honda shop manual...

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

Weird... I don't remember that part. Take a look at page 90 in the manual, though. That might make it a bit clearer?

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

They must have changed the design at some stage, I have just pulled mine apart and I have the steel bushing as in the pic above, nearly brought the bronze bushings and glad I held off as mine is like new and so I will reuse it

Can anyone confirm if the swing arm has an option, maybe its a difference between a CB360/CB360T/CB360G???

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

360 never had 'steel' bushings, they are a nylon composit pressed into swing arm and not shown in the posted pic.
The steel tube/spacer (collar) is clamped between frame tubes and swing arm pivots on it not the swing arm pivot bolt which just holds everything together
350 could have steel/cast iron combination

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

Interesting, maybe someone has modified mine

I'll take some pics tonight, they have done a good job and I will be leaving it as is 8)

My swing arm has a stamp on it of 730919 which leads me to believe the manufacture date Sepember 19th 1973. Which is consistent with my vin plate.

Here's a pic of what I've got which is consistent with page 92 of the shop manual. The diagram on page 90 is not consistent with what I have. And that sucker is in there too...

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

OK, the matte edge is the flanged end of bearing.
You NEED to get the center tube out, it should be completely free to slide/rotate.
When it's out you shoul be able to see the edge of bearing inside pivot tube (and clean the rust off the pivot tube /collar)

I'll get some pics.

Yeah it is not free to rotate... I got it to slide with some pretty serious hammer blows. (3lb sledge and a 1" drill rod as a helper to keep from flaring the tube.) Maybe an inch or so... I'll put some heat on it and see if I get any further.

'74 CB360 cafe project - (Swing Arm Bushing Question)

Ok, I got that summabitch outta there... persuasion was the key... That sucker was rusted to the bushings no wonder I thought it was a bush...

After cleaning it up...

Good thing I did order the bronze bushings...the chrome on the shaft race is pretty crappy. I polish the race on my buddy's lathe. Is this a part that I can actually buy still?

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

Bugger, you already got it apart
I believe they are still available from Honda?
It isn't chrome plated though, you can probably polish i out with some fine emery

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

Now you know why there is a grease nipple on pivot.
Pity it never got used

Huh? What am I missing here? What grease nipple on what pivot?... Not on my swing arm...

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

I'll have to check, but, if early ones didn't have it, drill and tap for one

 

[pandknz]

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

Mine has a grease nipple (1976) and I was correct, looks like someone has made steel bushings for mine and a good job they have made also

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

You could always look at ebay for another complete swing arm. I got mine for $35. It was in great shape. And disassembled for me. I got new bushings at honda shop.
heres one...shipping is a little high. But there are lots of em on there now.

Re: '74 CB360 cafe project - (Swing Arm Bushing Question)

Thanks for the link, that's the best one on eBay since it's complete and not rusty as all hell. I snagged that... $45 shipped isn't too bad. So Yes there are CB360 Swing arms that do not have a grase fitting... the rod for the ones that have the grease fitting have holes for the grease to go from one race to the other... not on mine. We'll trash this one and not let it back out in the wild. I'm scheduled to take everything to the powder coater next week. Hopefully the new swing arm will get here quick enough to prep and send along with the frame.

Re: '74 CB360 cafe project - (Getting it ready for powder)

360 doesn't have the pivot bolt gun drilled. (XS650 does)
There is a boss welded on to 'top right' with 60 degree (?) grease nipple.
I'll post pic later

'74 CB360 cafe project - (Getting it ready for powder)

Okay, while I'm waiting for my replacement swing arm I am getting the stuff I am going to have powder coated ready. Started on the front end today, got the fork lock cut off and the stump ground down.

What other items should I be sure to have coated.... Frame, swing arm, triple trees, kick stands, shock springs, lower fork tubes maybe, (I am planning to not install the center stand but I'm leaving the mounts...) Any thing I am not thinking of? The chrome on my rims looks good, I was planning to polish the hubs....

Re: '74 CB360 cafe project - (Getting it ready for powder)

sounds like you got it covered. Cant wait to see the fresh powder it will be nice.
AND when it comes time to install the forks back in the triple...DO NOT overtighten!!!
Find proper torque values in your manual, and use your torque wrench. It WILL crack w too much. And its not as tight as you might think.
