Bill,
I assume that the 555 has a JD 382 , I know the
55 does . You are right the parts supply is quite
limited . Those are one of my favorite engines to
work on , I have several ,but mine are the hopped
up model having a lanchester balancer in the
crankcase and a roosa master fuel system driving
from where the distributor would mount on a gas
model .
I build or modify other parts to keep them
running . I use case rod bearings for rod brgs,
have to hone .025 out of the rod and narrow the
brg about .100 , works well. Also make mains
from other brgs ( large MM rod brgs), piston
pin and pin bushing are from 4.5 inch cat engine.
I put GI's in the ring grooves and bore and
install dry sleeves in the wet sleeves . Oil
pump is mounted on the balancer and are prone
to wear as the balancer bushings wear and none
to be had. I use 6.2 chevy oil pumps and mount
them on the end of the balancer , make more
oil pressure than it had when new.

In your situation , I would pull the pan to
check the brgs , the rest of the engine will
probably run a long time .

holler if you need help.

george
