    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?

    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).

    1987 cat-426 no 1st gear

    I've had 4 tranny problems in the 20 years with this machine but this last one is a new twist. Shifter has had more of a tendency to spring OUT of detent in 1st gear than any other gear for quite a while now. Today the rig stopped engaging at all in 1st, the lever goes into detent but it doesn't...

    Deutz 912 injection drip timing degrees

    Reading the manual it says to 'commencement of delivery' at the degrees given on th engine plate, but the plate has no degrees on it. Nor do I see degrees in the manual. I know there are other methods but I wanna learn doing it it this way.

    Autonomous (thermocouple) cyl-head temp system for air-cooled engine?

    I'm looking for one or more thermocouple (washer or probe type) cyl-head temp sensor/indicator gizmos for a Deutz 912. The probe removed has a bayonet connector-catching contact so it's pbably a thermal resitor. What I'm after is one that requires no electricity, with 3-5 feet of wire plus a...

    Deutz F6L912: unknown fuel/intake-manifold sensing/connection

    On the left of the picture is a plug in the intake manifold which looks like it has an electrical connection stud on it but is also posdsibly thermal or baropmetric in nature. I simply don't know. That line is connected to what looks like a solenoid on the bulkhead, the other port is...

    deutz hydralic clutch cooling fan

    My Dx-6.05 has an also Deutz F6L912 with a hydraulically clutched fan. It used engine oil pressure to engage the fan when hot. I'm removing it all and replacing with a full-time direct-driven fan but have cleaned up the pieces and and am trying to figure out how it all works. Anyone familiar...

    mystery pieces II

    always some leftovers looking for a home (Deutz-F6L912 in 1991 DF-dx-6.05 tractor)... The gasket-kit leftover is probably for some auxiliary equipment my engine doesn't have, but the other one looks like maybe a flywheel shim and if it is then that would mean a no-ifs-or-buts clutch and...

    exhaust manifold coupling stuffing

    Years ago as I rebuilt the Perkins in my 1987 Cat-426 the exhaust manifold joint at the turbo was so worn out that even a new clip in there was going to be loose. The same problem surfaced with the Deutz 912 I'm building now. The new clip is around $100cad but because of the amount of wear it...

    calling out the Deutz vatican

    There's an awful lot of talent and experience in these parts so I come for wisdom. The first and only previous Deutz engine I ever built (in 2008) didn't have a hydraulics cooler. The (yellow) engine oil cooler sits in the air duct and it's exhaust is deflected away from the engine by the...

    Deutz tractor/engine kit 2 mysery parts

    The 912 engine kit I bought came with absolutely no documentation and there are some mystery pieces in it. 12 grommet type thingies with about 1/4" holes and a fine spring around the sealing redish rubber. Anyone know what these are? I don't remember seeing them during stripping. It's a 6...

    Deutz 912 injection pump-gear installation

    The guidance is a bit ambiguous so I'll shamelessly seek confirmation that what I'm doing is the right way ...IF it is the right way of course. Either way anyone googling for the info in the future should find it. I got stuck when I got to mounting the pump gear. This diagram is very poor...

    Yeah, the first ever broken easy-out in a broken bolt

    I think I could say my name is Napoleon and more people would believe me :-) THAT is the crank hub on which I did my number to a 10mm-1mmx40mm (flywheel) bolt. The easy-out is broken flush, what remains of both the bolt and the easy-out are stuck real hard. Is this a candidate for an oversize...

    dually wheel mechanism type identification

    I have a pair of duallies that I got with my Dx-6.05 tractor, the plan is to clean them up and sell them. Is anyone familiar with this type of attachment mechanism? Is it popular? It looks well done, does it have a name'? Link of my ad: https://www.kijiji.ca/v-view-details.html?adId=1647913815 TIA

    Should big tractor wheels turn with levers in neutral?

    My Dx-6.05 parts have started migrating back together, got the wheels back on today but they're BIG and I had a hard time partly because I couldn't turn them to align the hub bolts. I had expected to be able to turn them with the tranny levers in neutral, I'm looking for wisdom here as I have...

    brake caliper cylinder/piston polish

    This is my frist caliper job (Deutz-Fahr tractor). I cleaned the parts and need to decide if polishing the cylinder is required at all, and also if the piston is still acceptable, as I think it is. The plated piston hasn't been polished yet, something I intend to do with 400 or 600 grit tape...

    To gap or not to gap new rings pre-installed on new pistons?

    My best experience with rings ever was with a MaxiForce set bought for my Cat-426's Perkins 4-holer a few years back. Them rings were not just neatly packaged nor just pre-gapped, the gaps were all with about one thou of specs, not a one needed any filing! I'm building a Deutz these days and...

    '62 Chev 6-wheeler air-cooled brake compressor

    Once when I was anticipating a visit by a guy flying an antique airplane and had to secure 3 drums of ethanol-free mogas for him, a local garage partner lent me his diesel pickup just like that, no charge. A nice guy as we call such people, one good turn deserves another . Well, he's now...

    Deutz big-end bearing and locating dowel headache

    It's not a great picture but it shows the F6L912 connecting journal and the bearings. The dowel (red arrow) is not easy to locate properly and since during disassembly I had found a crushed dowel due to a misplaced and a bulging bearing subsequently worn down by the journal ....I wanna do this...

    Deutz-1991-Dx-6.05_assembly_parkbrakes

    The long road home has begun. The 'europid' models of these tractors use separate brake axles (forward of the main axles) including main brake discs, a front axle disc, and park-brk drums wirth shoes. Both shoes were new-size but one was damaged, glued the damaged part back on with HD epoxy...
