Crankshaft?

[Dutter]

I'm wondering if I need to find a different crank as I just bought this machine blown up. Anyway the right/clutch side crank bearing slides on or off with my hand with no effort, shouldn't this be a press fit? Does this mean I need a new right side of the crank? Maybe I should just buy a new Hotrods crank??
Anyone know?

you have the crank out of the cases and the main bearing is sliding on/off ?

I've seen some that slid off, and some that you had to press.
Biggest thing is no up/down play on big end of rod, side clearance and small end side/side is within spec.
With little oil, bearings should roll smoothly.

Correct!

 

[Awk08]

if there's no scarring of the crank under the bearing, you should be good to get and use new main bearings, if....the specs about the rod bearing posted above check out ?

Rod and bearing are toast so I need to rebuild it

 

[Blaner]

Sounds about right! Chances are that the crank is worn where the bottom rod bearing runs, check it out

New crank (rebuilt) = new bearings. That was easy.

And if you're at that point, replace the counter balancer bearings. Peace of mind = priceless.
Don't forget new seals.

I'm not sure why my pistol us misread, but it says the right bearing, not the rod bearing. I guess I'll chance on shipping. Thanks
