Went to take the pump off and spent a good number of hours trying to get the pin in the flywheel and the lines on the rotor to line up to no avail.
Finally just lined up the rotor lines and pulled the pump leaving the flywheel where ever it landed. My thought was that as long as the pump shaft stays in the same place and the lines on the pump are lined up on reassemble worst case is it comes out 180 deg out of time.
Am I correct, or is this going to be a bigger problem?

TDC on flywheel
Not sure why you could not get the pin into the flywheel hole.
I do it with a big screwdriver and only takes a few minutes to find TDC.
You could get some extra experience if the pump drive gear moves.
Look at this picture in the link below.
When I bought this 450B, previous owner had been screwing around with pump and didn't read the manual.
Was a lot of extra work to get the timing correct again.

Got the pump rebuilt. Nothing to it... Anyone with half a clue and a micrometer can easily rebuild these pumps to spec. Bolted it on, aligned it to the timing marks, primed and good to go. Engine cranked about four times and runs smoother than it ever has.
fifty bucks in parts vs $1500 at the pump shop.
