motor mounting area has cracks from vibration

I just bought my first snowblower. It is a JD TRS27. But I got it home and noticed that there are a bunch of stress cracks around where the motor mounts to the machine. I assume this is from years of vibration. I was thinking of placing a 1/8" plate of steel over the existing problem area, welding it on and mounting the motor back onto that. That would raise my motor up 1/8". Just wondering if that 1/8" would cause any problems with my belts/tension? My drive shaft would be raised slightly, but that surely wouldnt be enough to affect it, should it? I mean, the belts are adjustable, right? Should the motor be mounted with a rubber spacer on the bottom side, would that prevent this from happening again, or do you think adding the extra steel will be sufficient. Thanks

Adding 1/8" thick steal shouldn't cause any problems. Like you mentioned, the belt tension is probably adjustable. I think your rubber spacer idea is great;that would absorb the vibrations a little and therefore keep it from happening again. Let us know how you make out on the fixing!

Take the cover off the pulleys and see if you can raise the belt up out of the pulley the 1/8-inch you are proposing for the plate. This may help you decide if your solution is viable.

May also consider just welding the cracks.

As abumpa said... check the belts. Im sure you can adjust it out though.. Worst case... mount the plate under the frame. That will support it, and not raise the engine any.
