CB400 Four Super Sport Restoration 1979.

[Sprinter]

Guys, moving on from the newbie section I thought it best to start a separate thread for my restoration. This is the first motorbike I have ever restored so it may take a while. I will post some pictures later on but for now I have a few questions that need your advice.

1 Whats the best way to remove the rivet from the steering lock as the frame is almost ready for blasting.
2 Head stock bearing seats are shot so new head stock bearing set is required. Is it best to use seats with separate balls or taper roller.
3 Fork stanchions are badly pitted. Would it be best to buy new pattern ones or get the originals re-chromed.
4 Whats the preferred method of painting/coating the frame and swing arm

No 3. Send the stanchions to Phillpots for hard chroming. Pattern ones are really not that good, especially if made in Italy.

No 4. Powdercoat in satin black (closest to original finish) but check with the company that's doing the work as there is satin and there is satin !!!

No 1. Claw hammer to pull rivet off, if you have not got the key, you will need to drill the lock out.

No 2. Fit whatever was fitted as standard.

OK, thanks for the good advice.
Well the center stand pivot pin is finally out. It took some moving but eventually it started to move with a modified air chisel bit being used in the air chisel and a home adaption to push the tube through the stand.
Steering lock drilled out and removed so frame is ready for refurbishing now.

Whats the best method of removing the cush drives from the rear hub?

OK, had a good day today stripping the old paint from the frame and swing arm and now the rust is exposed. What is the best way to treat the rust before commencing with powder coating or painting?

[Nurse Julie]

Blasting.

[Sprinter]

Right here is the first lot going for sand blasting and powder coating.
Is the nut that holds the clutch assembly in place a left or right hand thread because it's extremely tight either way?
Also wheel bearings, what's the preference SFK, Koyo, NTN etc?

[Sprocket]

How does it look now? Been blasted and coated?

I usually send the chainguard as well. I wouldn't send that lot for powder coating like that. Unless they are very experienced with bikes you will never get your bearings back in plus all the threads will be filled. Put scrap bolts in all the threads and cover the studs such as shock mounts with lines of nuts, and cover both ends of the headstock with steel plates bolted through with thread bar and do the same with your swingarm pivot. Powder coat is pretty hard and therefore bloody difficult to remove from area's it shouldn't be in. It's no use masking things off as they will sandblast the lot before coating so your tape will disappear. Good luck.
