Yep

Meh...what's a little lack of parallelness amongst friends and an assembly that will one day turn 14000 rims ?

It looks like the crank isn't true to the crankcase, the clearance on the right side varies a lot to my eyes when you turn it.
Crooked crank or a bad bearing pocket on the crankcase?

I think your crank is assembled poorly by our friends overseas.

Run It!

Second viewing, that right side lobe looks like it took a couple good hits.

 

[Canadian farm boy]

Definitely looks like a crank problem. Looks like the RH side crank lobe isn't true or the crank is bent. It looks to be angled towards the rod when the rod is at BDC

 

[tickbitintn]

It's WAY out....
Flywheel side is true.
I haven't put a dial indicator on it yet but PTO end wobbles also...
Would be a vibrating SOB... IF it held together....

I put one together before this one and was surprised at the overall fit and finish. It was going to be my "baseline" saw and I WAS going to build this one for class 2....

Heat and press

 

[Glock37]

remove screws and knock pins out heat bar plate with heat gun about 7 to 10 min the hold bar side case with glove and tap crank out of case with block off wood or it may fall out repeat for other side
get a bearing sep and pull bearings off crank and they can be reused

no need to ruin bearings just may need gasket and seals

install oil pump to install bearing in pto side

Get another 10.00 crank and start over. lol

Wtf? I thought they were only $7. They keep raising their prices and nobody will be buying them.

Heat and press

nylon cage on one side....

 

[GoBigBlue1984]

I honestly never heat them before pressing them in or out. All this time........should I have been?

A little assembly lube and bushings and the Dake does the rest.

 

[GoBigBlue1984]

Could just be a wonky lobe. How does concentricity look at the crank ends?

 

[drf256]

That's really annoying.

Would that be under warranty?

 

[mdavlee]

nylon cage on one side....

You talking about the crank itself or just the main bearings in the case?

 

[drf256]

A Husky Type C Forked case splitter would work great here.

When I've used it, it pulls the bearings off the crank.
