Quick and simple; will the relief valves from a 147 work in an 1811? I know they aren't auto relief, but would they otherwise be a direct swap? I have a friend who has an 1811 with bad valves (some idiot PO drilled them out so it leaks like a sieve


) and I have a 147 parts machine. If they'd be a swap, it'd save us both a lot of time and money.
I don't see why they won't but want to make sure before we go to the work.
