Just wondering if anyone uses the Merc. heat lamp when removing bearing races when rebuilding an out drive?Does it really make it much easier and how about using a heat gun.I was thinking the steel race would expand faster then the aluminum and make it harder to remove?Any thoughts

Thanks Nordic95

I have used M.A.P. gas to warm up drive cases with success. Most times, you dont need to. However, you need all the help you can get, when getting a broken lower vertical shaft bearing out of a case.
