I bought 2 Amphicars one of which the engine is in pieces. As I was
putting it together and I noticed that the engine has no rear seal
(flywheel end) It relies on grooves to stop the oil from coming out. I
also noticed a seal the owner had bought the fit over the end diameter
of the crankshaft but not into the end cap (with out machining it). Is
this a good idea to add this seal? Do these engines leak? I rebuilt a
Bob Cat engine (Kohler) with the same type of oil grooves but it did
not matter if it leaked because the connection between the engine and
the hydraulic pump are sealed.
I can machine the cap myself so that's not an issue, if I should

Keep it original - the way Triumph designed it - and all will be fine. All the parts are available without problem and at reasonable prices.
With basic care and feeding these engines don't leak andlast well over 100,000 miles. The three areas that then need attention are cylinder bores and valve gear (as expected) and a slightly more unusual one - crankshaft end float. The end float is adjusted with shims - measure the end float and add shims as necessary to bring it back to tolerance although there aren't many Amphicars that have done enough miles to need it - I added a shim to mine a few years ago when mileage was around 50,000 as the engine was out anyway but it probably wasn't really necessary until about 70,000 miles.
I'd like a copy of that when you get it wrapped up, if at all
possible. I posted a list some time back, but id like to refine it and
maybe create an authoritative list that we can post on the club
website if possible.
