CB77 restoration by a newbie in Scotland

[eddiebpool]

Yes. Did the search thing and found that you had just asked the question. I too am hoping someone will be able to tell us which colour aerosol we need.
Like Grey there are many shades of Blue.

Best of luck with the resto and make sure you are sitting down and have the smelling salts to hand when you get prices from David Silver.
Made me go quite light headed they did.

Thanks Billiam, I will do my best to get the old girl looking good. I'll have to keep the costs of parts secret from my other old girl!

I'm going black and silver for this bike. If someone could suggest a tough paint that would work on the frame parts and look original I might be tempted. I'm finding bits of blue as I dismantle and it would be nice to keep the bike as Mr Honda intended.

Taking the crank apart isn't particularly hard. Restoring it and putting it back together is a little more challenging but immense fun.

Hello Eddie

I have some used cranks and stuff if you get stuck. I think its best to strip any used cranks you get these days, even when they "feel" good they can be in a pretty poor state. No point in spending on pistons etc. then have the bottom end give trouble.

Hi Gordon

PM sent, used crank and plenty of stuff would be very useful! Generally speaking, is there a way to check a crank to ensure you are getting something usable? I would focus on smooth bearings and no slop in the con rods. Beyond that you can't (as best I can see) check the condition. I think taking a crank apart is a lost art. I'm not building a racer. This bike will likely never see the red line or a rainy day so usable will do fine.

I have managed to source enough bits to get my rolling chassis off the ground. The project begins next week. I'll post pictures.

Quick question - I can't get the chrome fork seal holders off. I'm thinking hit it with plenty heat. Would this be a problem anywhere? I'm repainting so not bothered about a bit of scorching and the seals will be replaced of course.

I was thinking about fabricating a tool. I've tried an oil filter remover and a bit of inner tube for grip with no luck. Any ideas?

Yes heat will help but a good tool will save any damage to the seal holders.

This is what I made for the job. It will do CB, CL and CB160.

Love it, I'll see what I can do.

I done the best I could with my typically crude and over engineered way. I started off with some 3mm angle steel and cut the long parts 300mm for a bit of leverage and the short parts 55mm to give a little wiggle room on the inside. I have a vintage clamp to create 90degree angles. I created two "L" shapes with the old clamp, g-clamped them together then welded them up. Please don't judge my ratty welding, it isn't my best skill!

I was planning to do a 4 sided tool. I started with 2 but after trying to line up number 3 I made a mess of it. I had a workaround if I wasn't getting ongoing the grip or if the studs broke. 3mm steel doesnt give too many threads or lateral support so i welded on a couple of nuts to be sure, In the end I didn't need more than two studs. After a good roasting and a little bit of force both came off without much complaint. Job done, pics below.
