I need some help here !!!! I have a thunder tiger .46 pro that I have tore down in order to change the bearings.
My problem is that I can't get the drive washer off the front bearing area in order to pull out the crank shaft. By looking at the engine diagram parts list it appears that it pulls straight off the front. I have been trying to use a gear puller with no success. When I start applying pressure it gets so tight that I can barely turn the gear puller and I am afraid to force it any more because something mite break !!! Any other suggestions on how to get the drive washer off this engine without damage to any of the parts. Any help would be apprieciated !!!

I also heated the engine up in the oven to around 250 degrees but still nothing would budge!!!
