Volvo Penta KAD 300 Supercharger clutch

[jdwcs]

Started by KAD300 yesterday and lots of smoke from the supercharger clutch. It got very hot and it's clearly seized.

I understand that these clutches are manufactured by Ogura - does anyone know the part number or supplier as I suspect they'll be a lot cheaper that Volvo!

Also, any experiences of removing and refitting?


cheers in advance.

I replaced one a few years back and I remember it being quite straightforward as long as you have some circlip pliers. I used the genuine Volvo replacement but certainly for the KAD42 and 43 the clutch is a Ogura so almost certainly will be the same for you.
I believe these clutches are also used with automotive air-con pumps so may be worth taking the bits to a local air-con specialist and see what he's got.

I guess you've already looked at http://oguraclutch.co.jp/e/index.html

Just replace one of mine on KAD 42
They are made by OGURA part number on the new Volvo clutch was OGURA clutch company Ltd Japan
Part no - OSC-MGO1-309 DC 12v
I tried to locate a cost just out of curiosity for a comparission once fitted but could not locate one

Straight forward to replace, need a 3 slotted pulley extractor as the out clutch is on a splined shaft £20 of EBay and a set of 8in long reach external circling pliers

I would be checking the supercharger isn't seized before fitting the new clutch.....

Good point. My clutch plates burn out therefore screamed when switched in. If the clutch was seized wouldn't the supercharger be on all the time?
