grinding surprises, nerdy details and oil pump fixes
A lot of people try to take the oil pump off without taking the key out of the shaft and mark up the hole that the shaft goes through. This was the case on the 55 that my dad is putting together. This is a fairly easy fix, you just put a dab of material in the hole and re machine it out.
I got my 976 stamp that I have been waiting for. This is a cool detail that we are now doing. Our 46 and 47 each had a white stamp with 976 on it. Our 41 and 37 horns are too rusty to tell if there ever was a stamp on them. I have only seen this on hummer horns and 42 to 57 horns. Have any of you guys seen the stamp on an original paint nine bolt horn, or a six bolt vl horn.
Here is an original horn off of a 45 big twin with the stamp. Pretty cool detail.
I prepped a bunch of stuff for aluminum welding tonight. This is the corner of Doug's 36 case. It had some pretty nasty repairs done to it in the past. You can see where I cut it with the cut off wheel in order to break the chunk out. Well I pryed on it with a screw driver and this chunk came out about a 100 thousandths above where I cut the case. Check out how dark it is, this has been cracked and ready to let loose for a LONG time. I don't know how to put into words how difficult it is to take a cut off wheel and grinder to a super early 36 knucklehead transmission case. After seeing this, I am glad that i did do it.
Here are some of the parts I ground on. Should be welded up and fixed pretty soon!
