Maybe he should replace this one as well, eh? A Kubota will have something in there similar, won't it?...
Volvo Penta GUMMIKUPPLUNG - Ersatzteilnummer 827615 - Schmidt & Seifert
After all, it might fail one day unexpectedly.
And it's only $360 bucks.
Then there is the gearbox final drive seal, and the crankshaft forward seal, and the crankshaft aft seal, and the valve guide oil seals.
They have all got to be changed too, don't they?
After all, they are 10 years old and might fail, mightn't they?
And when he is digging in there trying to get them out there is no telling what else he might find or break on the way in. I mean the engine is Japanese, and nearly all those fasteners will have been impact-driven at the factory, and man they are hard to shift sometimes, eh?
Imagination knows no bounds (nor expense).
The mind boggles !
