    Deutz engine help, BFL914C

    Cool idea! I just got the plugs and caps finally all in hand, plus some 90 durometer orings for the split flange, if I have to remove it. I also put some colored zip ties on the lines that go to a similar place, too. Taking lots of photos, too.

    Deutz engine help, BFL914C

    Thanks, I will look at those to supplement my mixed collection so far. I'll be able to valve off the tank fluid, so there shouldn't be much pressure on the lines.

    Thanks for the suggestion.

    Deutz engine help, BFL914C

    Yes, I did, but the mounts, the side mounted pump, and the bell housing/flywheel connect to the triple pump all convinced me to just get a replacement. The Jarraff company sold me an engine that they were going to get rid of. So now I'm interested in rounding up lots of huge JIC plugs and caps...

    Deutz engine help, BFL914C

    Thanks for verifying my dim memory. Just talked to the equipment manufacturer and the variant that's on the machine (with the new gigantic hole in the side of the crankcase) is not the original. Very close, since it has a charge cooler, but not the original. So, that helps since I can buy one...

    Deutz engine help, BFL914C

    Thanks, Oz, Plebe and Tones. Those references sure helped. I could really use that reversing fan! Especially in my Toro 580D which I blast clean while the turbo is cooling down....the fan sucks back a % of what my air gun blasts away, but I don't like to cut it off while hot. The cylinder...

    Deutz engine help, BFL914C

    It's on a Jarraff line clearing boom saw. Bought it at auction, idled it 15 minutes to reposition it after they delivered it, then BOOM, big hole in the crankcase. It had oil. It was still running when I shut it off and the dipstick is now at the 'add' line. How did they know it was going to...

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    Today's question: I have good power and ground at pins 1 and 2 of the multipin connector going to the monitor. There are a cluster of gauges on the left side of the dash panel, and they also show no signs of life when cycling the key switch 'on'; such as the gauges swinging full range then...

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    ohhh. Well, I already ordered an adapter, which is made for converting to J1939, but, like you said, it remains to be seen whether my reader can decipher it. Thanks again for helping me and all these folks with your experience.

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    While looking online for pinout of Cat diagnostic plug, I see that it EXACTLY the same physical layout of the pins, but missing a key on the center (ground) and very slightly different sizes of bore for the pins. Oh yeah,......it's wired DIFFERENTLY than the J1939 which is looks so much like...

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    Green wire off, no alternator output, so ordered a replacement. Tried to get codes, but the round data plug is slightly deformed, so going to make some pin extension wires to check the codes. Spent a good while looking for obvious wire damage since I was pushing trees around, and branches can...

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    Thanks for that little tidbit! I tested today with that wire in place, and that could be the common thread linking the instrument monitor and the alternator failure. Since I tested, I saw on the schematic that it is a data wire of some sort going to the monitor. Will revisit this!

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    OK, will do that, and I'll get the current meter set up, also. Thanks again for your help.

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    The black box is the sealed ECM or EHC (on the schematic, I think), which has 2 gigantic multipin connectors held in place by a 4mm hex socket screw each. The connectors stick out of the box at a 90deg angle. The connectors and the general layout looks like this, but without those 2 round vents...

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    Yes, the fuse is good. When I saw it on the fuse box, I was really hoping it was the fuse. If the alternator is 'self exciting', does that mean it has an internal regulator? If so, what's the 3rd wire for? I've checked during the engine running and there's no voltage output. I didn't bother...

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    Thanks so much!!! Just to clarify, A6 would be referring to the grid (A vertical, 6 horizontal) of the schematic? If so, that 80a breaker is the only one I've seen, and it passes current and voltage. Is it possible that the dreaded black box controlled all the gauges and alternator? Is it...

    Cat 953c 2ZN2090 suddenly lost all gauges and alternator

    It starts and moves, but no gauges or display when key is turned, or started. I deoxed the big connectors going to the black box (no corrosion noted), checked for ground continuity at ground strap of black box, checked all fuses, checked the two relays inside that fuse box (starter and master...

    JLG 40H problems and fixes

    I have a JLG 40HA, Deutz Diesel, bang bang controls. When I step on the foot pedal, mine does the same. I think that the idea is that when you need a function, you have to step on the pedal anyway, so why rev up when you're not moving? The electric actuator moving a cable to the throttle is...

    JLG 40HA wear pad question

    Wow, that's neat that you put in the illustration and the red arrow. I didn't even think of the possibility that it could be turning a sheared pin since there is some strain on the system, but the restrictors would cause that, I see now. Knowing what and where to look is a great help. Thanks again.
