Title: Silicone rectifier rubber holder
Post by: BigAl (Alan) on May 11, 2026, 11:52:28 AM

Re - Silicone rectifier rubber holder, normally supplied with the main wire harness (example CB750F1)
Would any one know the part number for the rubber holder or a supplier
Picture attached...thanks in advance - Alan

Looks more like the clutch safety switch to me Al. See if the 550f lists them separately

Its part of the safety circuit which also involves the clutch switch
DS quotes the 'Rectifier silicone' part No. 31700-124-008 but there is no rubber holder listed on the DS site (CB750F1)
Fitted to a number bikes, but I have only seen them fitted on the main wire harness

Thanks for the reply

Have a look at 38301-KJ6-743 looks like it might be suitable

No forget that.

Maybe 38306-107-670

Just googled both numbers...they come up as a Honda indicator/winker relay

Do you think the small indicator mount might work 38306 092 670?
The diode one is not shown so must come with loom

The lower number shows as the rubber mount for me Al.

Try CMS

Thanks for the replies, but none of the above numbers came up on the CMS site

After a bit of a search part No. 32135-124-300 'holder, coupler' did come up on the CMS site...not in stock, but its a start.

Thanks again - Alan

I have found with CMS that you frequently have to look at a different model to get the part number as although its on the parts illustration the item number does not show in the parts list

The 38306 092 670? Number comes up

Al, is it just the part number you need or the actual part? I have a used one.

Hi Bryan,  the number does come up 38306-092-670 description (suspension/winker) part. Supports a square type indicator relay.

Hi Julie, that's ideal. PM me and I will Paypal asap

I'm looking for 10 No. parts, will wait and see if CMS re-stock

Many thanks again - Alan

Al, i knew it was an indicator unit mount but from memory it is a similar size to the diode so i wondered if it might work for you, it is for the relay fitted to US bikes as against the UK ones

Hi Bryan,  the indicator (suspension. winker) is larger than the (holder, coupler)
I have attached a picture, the 2-way connector is 18mm across. once fitted in the rubber mount it's quite a snug fit to support the connector/diode

Ok Al, was just an idea, there are quite a few of those diodes on some Goldwings so used possibly there
