Hey everyone,
New here to the forum, but I have been browsing as a guest and have found several resources.
I have a new to me D5 96J that I purchased for a farm dozer. So far, it has operated great for what I have in it, but I have a few fuel problems and am hoping that some folks with more experience can help with some of my issues. The dozer has the scroll fuel system, and I'm going to guess that it is a late 60's or early 70s model as the serial number is 96J00697. All fluids and filters have been changed.
When I bought the dozer, it had a pretty bad fuel knock when under load. The dozer would run and push, and when bogged down, it would spin the tracks. The previous owner installed an inline fuel pump as he "thought" the fuel transfer pump was bad. I purchased new injector nozzles and installed them. The fuel knock disappeared but now the dozer bogs down when turning and has really low power, almost as if it is starving for fuel. I'm going to change the fuel filters again today but I feel like the problem is deeper than that. When I push something it will just stall, the engine will keep running but it will not spin the tracks. I read in the service manual that the transfer pump supplies around 30 psi to the injection pump. I know that this inline pump isn't supplying anywhere near that amount.
Does anyone have any insight into removing the transfer pump? The service manual I have is very vague on this.
If it is my injection pump, does anyone have any kind of estimate on cost to rebuild? Also, any tips on removal and timing of the pump would be super helpful.
I know my way around a diesel engine but this is the first caterpillar I have ever owned. I'm more familiar with Cummins and Deere engines.
Thanks in advance for all of the help!
