Never seen a hole in a piston like that. What is causing something like that ? Too much starter fluid, overheating or lack of oil pressure ?
Do you use original Deutz pistons and sleeves or the aftermarket ones ?
Nice work btw

Hmm, no holes in any of the pistons just lots of rust and corrosion from water entering the cylinders. But I do see in the one picture what you mean it does look like a hole. The kit I use depends on the customer, I myself prefer to use Memo rebuild kits they have a really nice kit and its about $4000 cheaper then the Deutz kit. I've found no differences really between the two kits

Just wondering , what rebuild kits other guys are using. We have used one so far in a F4L912 . 900 hrs on since rebuilt and so far so good.

Ruffcorn - if you don't mind saying what is the cost of a rebuild kit? Been hearing horror stories about deutz parts cost. One bloke I know who needed a new crank for his F2L912 said he was quoted $12000 and no there's no typo there...

I can pick up a top to bottom rebuild for a 6 cylinder, sleeves, pistons, bearings, valves, guides, seats, oil pump, rocker arm bearings and pads, cam tappers, injector tips, head and rod bolts, full gasket kit, and filters for about 3300 bucks versus 8000 for a factory deutz kit. I really wouldn't doubt that a 2 cylinder crank would be that expensive. But if you figure the cost of a new f6l the aftermarket kit makes it not so bad

Had it in the dyno this week pretty impressed by its performance pulled 103 horsepower and 252 foot pounds at about 2200 rpm

RC, very cool job n that motor! I love the absolutely clean minimalistic look of an air cooled Deutz. Don't know why, but I thought the 6s put out around 120 and Tq in the low 300s in N/A builds like yours. How much do they weigh? Are automotive trans adapters available or do you have to do it in two stages with an SAE adapter?

A F5L912 is rated 88hp at 2300rpm. The first series of the F6L912 put out 100hp and the the later series 102 hp at 2300rpm. You can always push a little more with adjusting rpm's and fuel injection. 103 hp on a rebuild is like a brand new one.
