Ms462 crank question.

[redlight066]

Waitin’ on you cornflake.

Nice to have you back posting again Dave. You ever make it south?

They weigh too much

Interweb says 500i weighs .2 lbs less than the 462

My scale says 462 is 13, 500i is 13.7

Nah, Rich.
Been a wild ride and we decided it’s best (at least for the short term) to shelter in place.
As Tom Petty said, the future is wide open.
South Carolina is on the list.

Come on with it. If you hurry you can skip the snow.....


And there’s 462’s here too. Not to get too far off topic. Lol

Just no strokers.......yet

We gotta have (hopefully) one more GTG in NY first, and I'll bring 2 ported 462s!

You can't "steal" Upstate Dave from us just yet!

The only pic I have for 462 crank..

Isn’t the 461 crank very similar to a 460 crank?

If it is, I don’t see it happening. The 462 case is super tight to make up for that front tunnel which adds volume.

Adding a 12mm 044 crank to a 10mm case takes clearancing An 046 crank would never fit, the counterweights are much larger and they weigh over 100 grams more than the 044 12mm crank if my memory serves me right.

I like the thinking though.

If anyone has a spare bad 462 case, I am looking for a builder case.

Sounds to me like an 044 crank may be the ticket.

That may be dependent on the weight of the pistons. Vibrations seem to increase fast when 460/big bore slugs are used on 440 cranks.

I know the 462 has a larger diameter piston, but I do not know the weight.

This was my line of thinking as well. I really don't think the cranks are going to be anything similar. That's why I was mainly wondering what size the rod bearing and wrist pin were. Rob the longer rod and put it on the 462 crank. Surely a decent machine shop could handle it.

I used to be a kawasaki tech and I remember in a few of the service manuals they had procedures in them to change the rod bearings pressing the cranks apart. There were some special tools involved for reassembly but nothing that couldn't be fabricated.

You may sacrifice a little throttle response with the longer stroke but I doubt it would be that bad. Of course the whole assembly would have to be balanced. You can always go lighter on a crank but heavier will get you in a bind every time. It's only a matter of time.

If somebody gets a crank out of a 462 I'd be interested in the dimensions. Main bearings, crank shaft, rod bearing size, wrist pin etc... should have measured my wrist pin when I had it apart.

Put me on the list for a 462 carcass as well if anybody runs across one.

Changing the connecting rod will not change the stroke.

Its almost like Ive heard that before.

Oem 462/pin 96g. Meteor 461/pin 82g.

I never noticed a difference

 

[Fruecrue]

Since the 572 was mentioned in first post...

48mm bore
39mm stroke

I’d be more interested in a bored 572 than a stroked 462.

272 piston 440 hybrids vibe noticeably less than the 460 piston hybrid saws. This is because the 272 piston is close to the same weight as the oem 440 piston the crank was designed for. It’s a subjective question... with different opinions of course though. Vibes don’t matter as much to some.
