    Deutz 912 piston bowl volume?

    Got me a new gauge and all 6 jugs are looking good 1 240psi 2 200psi 3 210psi 4 250psi 5 240psi 6 220psi Since my adapter is an old injector, I stuck a copper washer to its tip with glazier tape. Even this was not good enough on second tries with the same gum by then bathed in fuel. So I...

    Deutz 912 injection drip timing degrees

    Thanks. There are a couple of discrepencies between diesels that are over my pay-grade. 1 Using an almost identical pump, the timing on a Cummins 12-valve instead of 31 degrees is 11 degrees (5 only if it's a firepump engine). 2 The same Cummins has a compression psi over 400 instead of 240...

    Deutz 912 front gear oil supply circuits

    This engine will, in its winter role, execute what is known as a critical mission which must not fail once it has begun. So if the belt breaks and cooling stops then I run the engine until it seizes in hopes of getting to the end of my 3000 ft driveway/runway one way or another. BTW both...

    Deutz 912 front gear oil supply circuits

    This video show sporadic squirts but I can't identify any systemic spray in it.

    Deutz 912 front gear oil supply circuits

    The F4L912 that I built in 2008 came from a shovel and it had a fixed belt-driven fan with the exhaust downnstream form the cylinders louvered by a thermostat. Except for that thermostat not being entirely mechanical I thought of that as a safer design. Complexity ALWAYS increases the potential...

    Deutz 912 front gear oil supply circuits

    My engine HAD an oil clutched cooling fan return oil from which flowed into the front cover in addition to any other oil supply routing there if any. It is this any that I want to know more about because I have replaced the fan with a continuously engaged one without the clutch and its oil...

    Deutz 912 piston bowl volume?

    Thanks for the reassurance, I don't do an engine a day so it feels good that what I thought I had read before is substantiated. I've had a few issues with these sleeve-kits but nothing so major as to have a significant impact. I tried to borrow a gauge with a check-valve today but couldn't find...

    Deutz 912 piston bowl volume?

    Hasn't run yet, was liberally oiled with assembly oil, rollout & first start is is planned for May. I vaguely remember having read somewhere that spec-compression should never be 'expected' and certainly not at this stage but have no idea where I read that. Off-hand I'd like to see around...

    Deutz 912 piston bowl volume?

    The reason I thought of the piston-bowl was to calculate the effect of shims in terms of compression psi BECAUSE my 1st compression tests fall too low. The rings haven't seated but I'm not sure if that's so much of a factor. When I did the shims & fire ring (gasket) ritual I aimed to end up...

    Deutz 912 piston bowl volume?

    I should have kept at least one old 912 piston and measured the volume of the bowl in its top, I need this to begin calculating how much compression difference 0.1mm of shimming wil cause (in theory).

    Deutz 912 injection drip timing degrees

    Deutz #1 is flywheel end. For once it ain't Deutz who have it all ack bassward. We call left/right as seen from the back, so it follows that numbereing should also be from the back :-)

    Deutz 912 injection drip timing degrees

    Got the pump, the timing is DONE, Just going over all the mistakes I made in this single thread thinking about how to edit them out (my first time). I'm working on putting a video together to up it on U-tube when finished. It ended up being a much more difficult and attention/patience demanding...

    1987 cat-426 no 1st gear

    When people put dualies on, the main wheel valves go on the inside, might be a good idea all the time unless you have leaky tires that need frequent reinflation.
