CB 500 resurrection

[gary123]

No, Ive got to find or make (bodge) one.

Seat cover isn't original. Need a pic of the seat pan to see if it's on the right base.

500 didn't get the disc guard, the 550 did. You can leave it on though as most people wouldn't know that.

The countershaft is out of a 550 not a 500. Unless you've nicked the needle roller bearing off the 550 as that's a small oil pump on the end.

Check how many teeth the primary drive gear has got. They differ between the 500 and 550 as the clutch basket changed. 500 has 24 and 550 has 26 IIRC.

Change the damper rubbers in the primary drive hub, sure we've already told you that.

500 K2 had a brake guard? Or are we just talking about UK variants?

[Oddjob]

I don't usually refer to non UK variants as I don't know for certain what each country got.

[Sesman]

Thought as much.

Looks like the bike is coming along fine. Although not a conkers finish it looks like the purchaser got a reasonable deal and hopefully the resurrection will be worthy of the previous owners praise, although posthumously.

[gary123]

Does this look correct. It wasnt working when I got it so I dont know how it should be. All the videos of rebuilds I found on utube seem to be for the 550. [ Guests cannot view attachments ] [ Guests cannot view attachments ] [ Guests cannot view attachments ]

Looking at the pics I spotted the locating pin for the needle roller wasn't fitted for the countershaft, have they both been fitted now? Also make sure the needle bearings locate into them, sorry if that sounds patronising but better to do that than let you make a simple mistake.

The crankcase looks to be a 550 pair, yet you're using a 500 gearchange fork setup. Am I wrong?

The gearbox looks to be 550 or it's had a 550 needle roller fitted. The only way to know for sure is to start counting teeth on the gears, there are slight differences between the 500 and 550 gears.

I agree with Ken that the needle bearing on the LH end of the lower shaft in the bottom pic looks odd to me

[gary123]

OK thanks to both of you. No locating pins not fitted yet, and its not patronising, thats the kind of thing I would do.
They are deffo 500 cases but your not the first to think otherwise, not sure why.
The gears all came out of these 500 cases but given the state of them nothing would surprise me.
I have a 550 set so Ill count teeth. Would it matter if the needle rollers had been swapped for 550 ones?

Thought as much.

Just seen yours, beautiful, GLWS.

[Sesman]

Yours will be sound, Gary. You clearly care about the build. Keep it going…

[Laverdaroo]

just what Sesman said...

[gary123]

Cheers guys, I need all the encouragement I can get.

Cheers guys, I need all the encouragement I can get.

You're doing just fine Gary.

It wouldnt be fun if it wasnt hard work, frustrating, time sapping and uncomfortable nights spent in cold garages and not to mention, increasingly, eye wateringly expensive! 
Plus, it makes it all the more satisfying when it fires up. HUGE swell head rights are a given and the whole process aids in polishing your Anglo Saxon vocab.................. Tripple winner, Crack on Gary, its going to be a fantastic result..keep it up mate.

[Bryanj]

The 550 is a different bearing with an integrated oil pump to lube the gear shafts but it wont work on 500, would worry me it might lock up as no oil would be pumped

Copy that.
