Swing arm pivot bolt
« on: February 27, 2020, 04:59:34 PM »
I'm a bit baffled.
I'm putting together a 350f.
While mounting the swing arm, I found the bolt (axle) to be way too long.. How?

I have a lot of CB400f parts laying around, as I parted 2 of them out in the last decade or so, but to my understanding, a CB400f doesn't even have an axle with grease nipples like this, let alone one so much longer.

Diameter (14mm) is spot on for the frame and swingarm by the way.

Any idea what bolt/axle I have here? CB500 potentially?

Lenght is 32,5 cm not counting both grease nipples.

Do the footpegs mount on the outside?

No, that's on the lower rear engine mount. Couple cm lower.
Also visible on the photo.

Are there CB's where the footpegs attach to the swingarm?

Yes, early 400/4's

Ok, that could explain it. than I must have a swing arm axle of an early cb400f. I never had any larger CB's in the garage...

Are these axles rare, or should I just tap thread and cut it shorter?

I’m still confused,
Yes, early 400s had the foot pegs on the swing arm, but they were actually ON the arm between the pivot and the rear wheel spindle, not on the pivot.  I still think that pivot pin you have with the grease nipple must be from something other than 350 or 400.  I have both 350 and 400 bikes and will check tomorrow.   I also think I have the pivot pin you need for a 400 - might even still have a 350 too.

I was thinking that as well Ian... Yes, they are on the swing arm but not on the pivot bolt as you say.

Ok. Would love to hear if you have the right one.
In this case, i can only conclude that indeed it must be from another CB with a wider frame and swingarm pivot. 500f maybe?

Strange because I am certain I only took apart 2x a CB400f...

Hi Erwin,
Just checked and the 350 and 400 are the same length - give or take a mm, but as you know, only the 350 has the grease nipple. I looked through my box of bits and can’t find a 400 one but I do have a spare 350 one complete with cup washers, nut and grease nipple.
If you are not in a rush, I’ll bring it over in May (it’s March tomorrow!) but otherwise I can post it.

Hi Ian,

Absolutely no rush at all. The longer one I have fitted now will keep the swing arm in place just fine.

There's certainly more than a couple weeks worth of work on this bike, especially since I don't even own the rest of the missing parts at the moment  8):

Sorry Julie and Trig (and Steve!)
Didn’t mean to put cats amongst pigeons - could always say that we don’t have leap years in Orkney but the truth of the matter is that I knew that there will be 29 days this month but I thought it was Saturday already!

Anyway, glad I found the spindle for Erwin and as there is no rush we’ll look forward to handing it over in the Netherlands in May on our MX-5 trip.  PM me Erwin so we can meet up somewhere.
