CB350/400 / Re: 400 Wheel Spindles
« on: September 09, 2023, 11:59:00 AM »
I am currently fitting rebuilt wheels to my '75 400/4 that I restored in 1986 !
I couldn't find NOS DID rims in '86 so I used Suzuki Takasago rims (bought from Queens Park Motors
Oddjobb  :)  ) and non-standard un-butted spokes. Anyway, with eBay and internet, (not around in the mid '80s ! ) I have just rebuilt replacement wheels with the proper period DID non-side-scripted rims and the correct Honda spokes.

I noticed that my Aug 1975 bike had a hex headed rear wheel spindle fitted and it's not correct as it should be the -286- part ..like the CB250K , although I believe  it was BZP finish on the CB400F,  not chromed. Also I noticed that among my collection of front wheel spindles, some have hollowed ends and some are solid. I think the '75 should have the solid end,  BZP finished version. Any ideas? I think my original rear spindle must have been from a late F2 model or perhaps a CJ250T.


Going back to spindles. I have a CB550 F1 / F2 with a hex head and the flanged nut. Everywhere i have looked for the part number it comes up with 42301-300-020 which is from the 750  :o

Is there meant to be a small amount of side to side play in the rocker arms then?  I assume that's what they were trying to alleviate.

Rotor off tomorrow hopefully then I'll be able to see tge extent of the wear a bit more, fingers crossed!  Is there a point at which engine wear isn't salvageable, I might as well prepare myself🤣

All engines are salvageable, it is just down to cost  ;)

What length did he send you Ash ?
Extra length depends on how much extra. As all aftermarket lines will not be spot on  ;)

It's at home and I am at work mate .. approx. about 35mm

One we refurbished Julies 400, we used 390mm total length mate  ;)

Yes, I typoed an extra "0" in my message.  So for those that work on these engines regularly - that clearance (as stated in the manual), .05mm/.002" IS CORRECT?  In handling that thickness feeler gauge, it seems like pretty much "no clearance!"  :)

It is correct in the manual. All the rest: 500, 550, 750 SOHC are 0.08mm on the exhaust  and 0.05mm on the inlet  ;)

Nope, Mike has an extra zero  ;)

A UK guy on F.B. confirms that these are indeed the same as Italian Mold Lab. Wonder if DS is paying the supplier with credit notes  ;D

I stopped taking credit notes from Sliver years ago, hard cash only  ;D ;D ;D

Tappet clearance is 0.05mm on the 400.
I don't know too much about the set up on a 400 but, a expert will be along soon
