D2 pony motor balancer

Doesn't seem like much but to compensate, just grind about the same amount of material from the opposite side and you'll be golden. To remove the flywheel, get one of those cheap 10t hydraulic pullers from Harbor Freight and a couple of bolts and heavy washers from Fastenal. Apply the pressure on the puller and then tap on the circumference of the flywheel and it'll pop off. Leave the nut on about 1- 1 1/2 turns from tight so the flywheel doesn't take off

Thanks for the advice Neil ! Glad to hear it’s not ruined!

The hub has tapped holes to pull it

there has been a lot of posts on here advising us to never pull on the flanges---I think OM even posted a puller he designed to pull the hub off

You just need a regular two-bolt puller. Hydraulic enables you to ramp up the pressure before you tap

I made such a puller.... Two long bolts ( about 12" or so) that thread into the balancer. At the "head" end of the bolt a pieces of 1" thick steel about 8" x 2". 2 holes in that plate match the distance between the holes in the balancer. Place a hydraulic Jack ( that will work on its side - some won't ) between the plate and the pony shaft.

On a D6 I did this and had to use a cheater bar on the hydraulic Jack. I covered the entire assembly with a heavy tarp, expecting shrapnel to fly or the Jack to blow. There was a loud bang, but the balancer popped off.

What is a “Balancer? I’ve always called it a “Flywheel” and so does Cat. :confused2

I guess balancer comes from a harmonic balancer that drives fan belts on an engine?? :confused2:
