    another bosch p7100 problem: 12-valve won't keep running

    The last otherwise good run ended with a bit of overheat to about 230-240F, engine ran good and shut down normally. On the next start it fired but would not keep going past a few seconds. This same behavior repeated on each of maybe half a dozen subsequent attempts. Doubt very much if OH has...

    Deutz-Dx-605 cylinder head temperature gauge calibration

    As expected the rear cylinders are a bit warmer at low loads. I want to use an IR pointer to read cyl temperatures for and idea of calibration. Any one have any practical experience about how IR readings on the exterior of air-cooled jugs relate to actual temps on the inside? What's the best...

    Rear axle build (big ford in Cat-426 1st series) 03 outer-bearing & seal

    The LEFT axle (having lost some oil) was removed by a shop and that was when I took over! This left axle had a chewed up outer bearing, damaged race, and no seal found (probably discarded by the shop). I pulled the RIGHT axle and on it I found - the cone bearing in good shape - cast in-place...

    Rear axle build (big ford in Cat-426 1st series) 02 axle preload measurement

    The good book says to use a shim under the preaload bearing equal to the feeler-gauge fit. It looks like telescoping part 2 of the tool might be the thickness of the bearing and that the 3 legs of part one rest on the edge 3 so as to measure the shim that might be needed to raise the bearing...

    Rear axle build (big ford in Cat-426 1st series) 01 ring-gear remove

    My cat-426 ate the planetary and the ring-gear and a load of other parts, thinking of rebuilding it. The 2 halves are NOT identical, the left one 7E21 hosts the ring-gear in it, the right one is7E20. I prefer to strip non-destructively when possible; so how do I remove this ring gear in the...

    Good used parts sources?

    My Cat-426 rear (big ford) axle has eaten its planetary gear and ring-gear among other bits and pieces. I've never built an axle in my life but 82 ain't too soon to start :-)

    KISS dual battery system

    Both my 2018 Subaru and 2008 Totoyahaha Tundra have electrical systems completely gone awol so that leaving the battery connected results in depletion within 4-5 days. Thinking of two batteries in parallel with the ground wire connecting them routed to a switch somewhete in the dash. One battery...

    DIY control cables

    I had a ripped off front PTO control cable, a local dealer had another one made for me but he screwed it up (too long and the input end is just like the output with that extension sleeve or whatever). So now I'm scouting for DIY cable parts sources to maybe make my own. The two ends of the old...

    Ancient type dutch front PTO

    I don't think I have ever posted about this beast here, it's from my 1991 Deutz-Fahr Dx-6.05 in a time when front PTO's were just begining to make the scene (as far as I know). Does anyone remember these drum typesz and could still coach me about them? The pads seem to be worn to limits...

    mini-zerk or ***?

    I've never seen these lubrication fittings before, they were certainly overdue. A 5/16" eyeball joint, the fittings is barely 1/8" in diameter. In this application what is being lubricated, the threaded bore, the eyeball, or both? They're called flush-mount grease fittings but I see no...

    Pin fixing clips

    I'm fielding this under SAFETY because equipment controls, not to mention VEHICLE controls, ofter use them and when safety is an issue there can be no doubt left when the job is done. My FWD lever has this kind of pin lock what is this type called? It's a very good type but too thin...

    oil MIL specs

    My Deutz-Fahr Dx-6.05 is allegedly a 4.70 with a 6 cylinder engine, 6.05 doesn't figure in the operating manual (they call it Instruction-Book). The only documentation I have specifies one oil for engine, transmission, and hydraulics: API-CD(MIL-L-46152) OR API-CD*(MIL-L-2104C) *= "bindingly...

    surprise oil shower {Deutz Dx-6.05 rebuild}

    This isn't my first tractor but I've never built one before. Engine just installed, main wheels jacked up, front axle disconnected, transmission and range in neutral. I just wanted to start the engine for a few seconds to test clutch and things, a peace-of-mind exercise before pressing on with...

    Deutz-Fahr dx-6.05 clutch throwout bearings installation

    I don't have the manual but I've seen some other clutch release bearing removal and installation videos without presses or wheel pullers (just simply hand-fit). Rightly or wrongly, on this tractor, removal was definitely a wheel-puller maneuver! So I wonder how not to waste my new $300 bearings...

    how2 remove carbon from turbine blades?

    While I happen to have the (Cummins 12-valve) turbo removed and separated for other repairs, I notice carbon on the turbine blades. Is thee any point in cleaning it off with some spray (blades are not to be touched), and if so then what solution would you use? The deposit is thin, it's just that...

    Viton, Nitrtile or WHAT for diesel fuel sealing?

    The last metal fuel tank I made see @ 1:10: was aluminum with a polycarb inspection window sealed with either Viton or Nitrile (I forget which). This page quotes both of those products as 'EXCELLENT' for the job. https://www.marcorubber.com/chemical-compatibility/DIESEL%20OIL ..but as...

    grammer seat leakdown

    The MSG95A/731 seat's in 3 or 4 pieces on my bench, just had the seat cushion re-upholstered. The compressor pumps it up alright but it I then leaks down when I lean on it. Thinking of pumping it up and then dumping in the bath-tub to see where little bubbles come out. Is this a stupid idea?

    is a pilot bearing an engine, transmission or clutch part?

    I ran into a worn-out pto clutch release bearing problem and have decided to take a much closer look at the pilot-bearing as well, seeing that the tractor, still split, presents a much better opportunity. I tried to identify the part # and availabilty but see no trace of one anywhere in the...

    clutch friction disk directional pads

    Having no manual I did my clutch assembly with reference to an exploded view in the parts book to see which side of the friction disk went which way. NOT a great method, admittedly, it showed that the hub riveted onto the disk went on the transmission side. In this image that is toward the...
