Title: RD400 hose clamps
Post by: RattlecanResto on May 27, 2020, 12:39:26 AM
I am looking for the original style clamps for the rear brake cylinder to reservoir hose. So far I am unable to find a picture. Does anyone have a pic or know what type of clamps were used?
I am fixing the brakes and am trying to do resto style in case I decide to restore this bike.
Thanks!

No clamps other than some rubber wrap bushings on the hose along the stock swingarm tabs.

This is the current part but no photo
Yamaha 90601-11525-00 CLAMP, HOSE

I have pics of the ones on my 400 but not sure if they're OEM.

Yea, I ordered the Yamaha part number but they just sent screw type clamps which I suspect are substitutions for the original. That's why I'm trying to see what the original ones looked like.

The ones on mine are slotted hex-head worm screw type like Mark mentioned. I have a take-off rear master setup from a CAN RD400F/G in the garage I can look at to compare.

Checked my spare rear setup, it's got similar clamps but they don't appear to be OEM because they're a little too long for the application. I'm sure Yamaha wouldn't use oversized clamps.

My brother has a '77 that is nearly 100% original. I can check what his has on it.

Here's a closeup of a marking I found on one of the clamps on my '79

Based on info in old parts books I believe the original part number is 90460-16068-00  HOSE, CLAMP
which was superseded by 90601-11525-00

I have 2 RD400s, one I bought new and both look like this. Quite a bit of extra length hangs out.
