400 Wheel Spindles

(1/7) > >>

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.

Hi Ash,
My '75 400 (first reg Nov 75) UK bike has a round head rear spindle (with tommy bar hole) and is (and was) BZP.  Front spindle is solid end BZP.  The 350 front is the same but the rear is round with hole and chromed.

My 1978 400 has the hex head rear spindle.

That's probably what you expect for a later build.

As far as I can remember early 400s had round end with tommy bar hole, my 75 has, later with hex head which my 78 has, according to my parts book the rear spindle changed at frame number 1065686 but no indication as to which spindle.
I have three front spindles, and all have the hole, the parts book doesn’t show that there was a change in front spindle.
All BZP.

The hex head one is a bit of a mystery as it doesn't seem to show in any 400F or CJ250 parts book I have. I discussed this a while back with Chris Rushton,  who knows a thing or two about CB400F's. He found a NOS one but it was too long for the 400F  and I guess a CB250N part. I have found a -312- (SL350) part that I think is the correct style and length but not showing as ever fitted to the 400F. The round rear axle with tommy-bar hole one was, I guess the 286-010 part when chromed and 286-020 when BZP.

I saved the pics of the 'Push-mile only' CB400F2 that Silverstone auctioned a while back and it clearly shows the hex rear spindle and the non-hollow front spindle. I guess the hollowed front  ones I have came from a CJ250T.
