If you do manage to find bolts for it and bolt it back together, be sure to use" "loctite" on the bolts so they don't vibrate loose again.
Even though that engine
has a big flywheel to smooth rotation, it jumps around quite bit as I recall
. Could be the reason that red " coupler" was installed.
I seem to remember my Volvo
MD7 as not being very smooth, especially at low rpm
The " raw water" cooling
is another unusual feature of that engine
. On my boat
, I had to periodically remove the cylinder head
so I could ream out the salt
residue in the cooling
passages around the cylinders. About every 2 years I had to do this. I just lifted the cylinder head
, removed the cylinder head gasket
and went to work
and then just replaced everything, using the same cylinder gasket
. It never skipped a beat..
Despite all that, it proved to be a remarkably tough and dependable engine. I had it in my boat
for around 10 years, but finally traded it in for the newer 2003 series...even more remarkable, I found out later, that someone had bought my old engine.
