I posted a little while ago about a motor from a power unit being used in our 1941 LA. I am not sure what year the power unit is or how to find out. All I know is the serial is G-017596. I haven't found other useful info on it. From the outside the motor appeared to be identical to the LA motor. I used the radiator from the power unit because the LA's original radiator is beat up a lot.
I had to use the flywheel from the LA's original motor because the flywheel from the power unit didn't have the teeth for the starter.
I got the clutch all put in and discovered that the tail housing would not go in. I figured the clutch wasn't centered but it was. Turns out the block casting is slightly different from the LA motor to this power unit block. Is it the same motor from an L?
I removed one of the studs and the tail housing went right on. So for now it has 4 bolts instead of 5. The fifth bolt hole doesn't line up. I modified a stud because the stud hole on the tail housing and the stud hole in the block are off by about .020". I figured some kind of stud in there is better than none.
That's where I'm at now. It seems to work good for now. I planned on eventually rebuilding the original motor but for now this will hopefully work. Its just going to be driven around, no heavy work,
