    Cat 735 a/c problems

    If the gauges equalize quickly to the static pressure after shutdown, there could be a broken valve in the back of the compressor. If the valves are good, it takes a few minutes for the pressures to become the same. Do you have any way of checking your scales, because it could be low charge...

    2019 CAT 259D Lose Power after warm up

    The first time I repaired a 289D with the low power after running for a while, it was due to no.4 injector fault. After replacing it, we put it on a test bench & it would stop injecting after a couple of test cycles. The next time it played up, it was due to the E459-2 fault code that was...

    2019 CAT 259D Lose Power after warm up

    I'm sorry I can't help further, it was late last year & I didn't keep a picture of the injector. I know I had to try a couple of times because I wasn't reading the number properly with my failing eyesight. I think D, O & 0 look pretty similar.

    2019 CAT 259D Lose Power after warm up

    ET accepted the Denso numbers from the injector when I changed one on a 289D. It was only asking for the numbers, not a trim file like other Cat engines I have changed injectors on.

    299D2DC2 SKID STEER E459-2 DOES START AT ALL

    Hi, I just had to locate the cause of the E459-2 code on my friend's 289D. Thanks to the several threads on this site, I was able to look for and find broken C903 Blue wire near the connector on LHS of firewall under cab. Goes to pin 27 on that connector. It is the earth for the coil on the...

    Cat 289D Engine miss

    I had to replace the No.4 injector. (Used a genuine Denso 295050-1980 unit because it was much cheaper than what Cat dealer was supplying.) The local fuel pump shop put the old injector on the test bench & found that it would start playing up & stop injecting once it got hot. It would work ok...

    Cat 289D Engine miss

    Thank you. I'll check these things next time I'm at the machine. (100 miles away). It already has the updated fuel transfer pump.

    Cat 289D Engine miss

    I've just had a look at a friends 289D that develops a miss after running for about 15 minutes. On the second time it did it, I was able to isolate it to No.4 cylinder by doing cylinder cutouts with the laptop. After shutting down briefly, it is good again for a short while & then starts to...
