I need to get the flywheels off the 16-2 to reposition and replace the seals. Also there is a pulley for a fan that I will not need so that has to come off. A month of soaking in oil and running the engine with the gib keys out would not break things loose. I even gently heated with no luck. It was time to get serious.
I hunted around for a puller. I hit up the local heavy equipment dealer and several large farm tractor shops but they had nothing big enough. We have an industrial equipment rental place and I stopped in there. They had Enerpac units but they were way too small.
I had a piece of 3/4 plate so I plasma cut 2 discs. I machined a fillet in one to clear the radius on the hub of the flywheel. I drilled and tapped holes then cut a section of the back plate to slip it behind the flywheel. I picked up a length of 3/4-10 grade 8 threaded rod and nuts from Fastenall and put it all together.
I have a small enerpac cylinder but that would not break it loose. Tightening up on the nuts, finally there was that pop and it broke loose. After some movement the little cylinder helped move the wheel about 1/2 inch then I reset the nuts and moved it again.
Finally both wheels were off, nothing was broken, or hammered on, and no torches were needed. Everything was done safely.
Pardon my mess in the shop.
