Re: Is it normal for the drive shaft to move in an out by half an inch??
Wow. Lots of responses. Sorry for the lack of clarification.
Sorry for the misinformation. The play is in the crankshaft on the forward side of the engine. Not the drive shaft.
I have a 32 year old Petter, AC1W diesel engine with 750 hours on it. (its in a sailboat that has been used mostly as a liveaboard all these years.
ITs a 6 1/2 HP one cylinder, that starts right even after several months of not being started. It is fresh water cooled with a heat exchanger which is the only reason it has survived all these years. I change the oil, pump out the old diesel and clean the filters once a year, although I only run about 5 -8 gallons through it per year.
I have never had a problem with this engine.
Thanks for your help.
