Petteroids / Petter piston shaft movement?, model type? & Hi
« on: November 23, 2012, 12:37:34 PM »
Hi, I'm a new member, so thought I'd introduce myself and say thanks for having this forum at all, and thanks to those who contribute.

A bit of background. A friend and I have just taken on a Petter AC1 6HP diesel.  It has been modified for propelling a boat, with water cooled exhaust and a forward/reverse gearbox.

So I hope it's ok to start the ball rolling with the following:

1/ the data plate only says Type: AC1.,  BS: 6.00,"  the engine number and then "AC1" again
The manual says there's should be a year of manufacture, rotation direction and a build number. But none of these are there.
HOW CAN WE FIND OUT THESE DETAILS...?   So we can get parts and understand the workings.
I think it is an indirect injection model, ie: the injection nozzle goes into the side of the cylinder head. Is this right..?
It also has an onboard electric starter motor.

2/ the cylinder head is off and the piston head removed. The piston connecting rod when wiggled has quite a bit of sideways movement (about 4mm or more)... does this mean the big end bearing needs replacing...?

3/ Mechanics have told us that "no one wants these any more". They recommended that "much better/modern alternatives" are available for the use ours has been put to. But the alternatives they recommend look too heavy for our 70 year old 1/2 ton wooden boat. In principle, we would much rather stay with the petter, not least because we like old tech, as opposed to new tech. But the mechanics made us doubt : will the petter be reliable? and will it power the boat at least adequately in up to moderate seas? Any input/experience you guys have, or have heard of, would be greatly appreciated.

Any thoughts..?
