Petteroids / Petter PH Flywheel (not a gib key problem!)
« on: February 20, 2012, 09:08:12 PM »
As I wrote the title of the thread, I had to add the comment about the gib key as I imagined most people would groan "not another stuck key". This time it isn't a stuck key!
The engine is a PH1, pretty unmolested, down on compression and needing an overhaul. I got it for not much more than scrap value on the 'bay, and I'm going to ovehaul the bits that need doing before it goes in my dump truck. The dump truck engine is also down on compression, and is pretty unwilling to start on a cold morning.
Anyway, I got a gib key puller, and with loads of WD40 and about a week of tension, it popped out. Perfect.
Except it isn't. The flywheel is completely stuck solid. I've tried walloping it with a leather mallet, I've tried jacking it off with a one of the big bolts on that side of the engine. I've even warmed it with an oxy blow torch (warm is an appropriate word, that thing can absorb a lot of heat), and it isn't budging.
So, what is the trick to getting a keyless flywheel off the crank?!?!
