Hi Paolo,

it is wonderful to see, that you progress with your MAH916. Hope dies last !

For me - and also I include all friends in this forum - is the highest happiness
when technical equipment (maybe engines, farm-Tractors etc.)
whichever appeared dead, by technical tricks, connections, experiance ect. from helpful friends
someone can beheathe life in it and it is "reanimated" and we can hear the pulse rate of our "little sweetys".
"pop.pop.pop.pop......"

For further problems follow this thread.

There are a lot of friends who are very interested, extraordinary helpful and enthusiastic.
Let us partcipate on your success. We all are enjoy if it runs anytime.

Keep up the good work !


Best regards
Karl

Hi guys, here some updates.

Today it's a no-rainy day, so I've decided to go at the farm workshop to wash the MAH with high pressured hot water. I've removed a lot of dirty from outside and inside motor.

Here some photos after shower: motor got clean, and me got dirty and wet a lot

this is the powerful machine (70hp) that help me bring motor on the road..




After made photos, I restart to assemble motor.

Once I arrive to fit the piston, I was stop from one dubt... please look the photo below.



Piston and crankrod are not symmetric, but piston has a hump, and crankrod a hole. Now the question is: the piston hump and crankrod hole mut to be mounted faced above or below?

Sorry but I've not checked it when I've disassembled my 916.

Since it can not be mounted, I've checked the oil pump with new oil, and have looked that's work so well.
After this, I've opened and cleaned the injector.

See you to the next update.

Paolo

Hello Guys,

15 days ago i've received the new exhaust valve from Graf Motoren and I've try to restart engine but, at the moment, I've only seen a lot of smoke, but it won't start...
Today I will re-try to start it..

I will inform you if there are new updates.

Hello guys,

I've started the MAH916 !
With hands, i was unable to start it, than i've made an adapter to start it with tractor PTO.
After a lot of turns, motor start to smoke a lot, and it start after more than 30 years.
But, unfortunately, it start to go up with RPM, probably regulator don't work or diesel pump has some defect, and, at the end, motor go to over-RPM and broke exhaust valve guide and exhaust cam rod was bended.
As soon as possilbe, on autumn or winter, I will check about what's append.
