Top end is off and ready for the machine shop but I'm stuck with the oil pump. I've got the brass nuts that hold the oil line in place loosened but can't figure out how to get the pump off. Manual says, "Remove oil pump retaining sleeve lock screw and remove oil pump and pump to block oil line."
Their exploded diagram doesn't show a retaining screw and I sure can't find one. So how do I get the pump off/out?
Thanks.

Should I also remove the cast piece that bolt is in (which is bolted to the block)? Or just leave it there and the machine shop will work around it?

Do they charge a flat rate for an engine teardown, or do they charge by the hour for their work? Some shops do not charge for the teardown if the repair/replacement parts are sourced through them, but I would make sure and know this sort of thing.
I'm commenting here because I have had all these conversations with several machine shops the past two months-- each one was different.
Give 'em a call.
