Hello all, I am rebuilding a Husqvarna 51 chainsaw, changing bearings on the crankshaft and needed to split the lower case apart. Did not have the tool to split the case and did not want to spend $80.00 on one either so I made one. It's been done before so no big deal, and not as beefy as some you might see, just used what I had. Cut it out of 1/8" plate steel with my plasma cutter and used a 1" square tube as the base to weld to. Used 1/2" althread and two nuts. Once I had all the welding completed, I cleaned it all up and gave it a try, it worked great. My thought is that even with the lighter gauge materials used it will still do the job. Here are photos.
