What Crank Is This ??

I came across this crank a while ago. It was given to me by a kind person who know's I'm into 390 Auto's.
Out of curiosity I measured the stroke and came up with 74mm. The 390 and 420 are 71mm. The 430 has a 74mm stroke, but as far as I'm aware is a full circle crank. This one has what appears to be a water pump drive on the left side.
Or am I barking up the wrong tree ??

430 wc auto

But the 430LC Auto has a full circle crank does it not ? Or did they use this style of crank web on those ?

I think the bottom end is all based on the 390 auto, so it probably has a porkchop crank.

430 LC Auto has the bob weight crank

Thanks Steve. At least I now know it's not for me

The spare parts book shows a bob weight crank and I have had a quick peak in a spare motor, I guess with all that rotating mass of clutch full circle fly wheels would be overkill!

Stub ends seem to interchange from what I have seen in my collection

water cooled 430 auto.

The auto cranks I have actually held, the 420, 430, and 500 all have a shorter (than the standard shift models) rod pin because of narrower cheeks. They are all pork chop shaped as I call it. My guess is the intent is to have it rev up quick and have a minimum of weight. The 430 has a shorter drive stub as it has only one needle bearing where the 500 has two and the 420 has bronze bushings and the one way starting device. There is a picture in the 430 manual that really is from the 500 that can confuse things if you do not actually hold the parts. I am not sure off hand is the ignition key on the other stub is in a different location on the various models, the 420 I think is different than a standard shift 430/500.

Never mind about that! what about BRExit driving the UK into recession!!! what will Andy at HVA do???

Personally, I don't think it would make any difference...

Too old to come and live in Australia now!

LOL...all the sunshine here will ease those shoulder aches .....im about to drive 2000Kms to attend Classic Dirt on the sunshine coast with the 510 in the back. Heike Mikkola is attending and im thinking his moniker on my sidecover would be pretty cool. sorry..thread hijack alert!!!

If anyone has a set of 430 auto cheek weights or a 430 auto core crank or a used 430 auto crank send me a pm I've got a project that need some for. Thanks for any help
