    John Deere 435 Diesel Oil Pressure Issues

    I had a 185 thermostat in it, however on hot days in Texas (over 100 OAT), the temp would creep up, so I elected to go with the 165 to give me more creep room. I know my radiator is in good shape, I had it overhauled a couple of years back. With the 185 the temp would reach about 200. Given...

    John Deere 435 Diesel Oil Pressure Issues

    Got the oil pressure problem fixed! Thanks for the help and suggestions. I had two problems. First the oil pickup tube had been pushed up towards the crankshaft. The top of pickup tube screen housing was concave instead of being flat. This resulted in the pickup being elevated above the...

    John Deere 435 Diesel Oil Pressure Issues

    Unless anyone else has a better idea, my next step will be to remove the oil pickup assembly and check it carefully for cracks or leaks. Another thought I had was possibly the oil level is going too low and the pump is picking up air. The dip stick is not original and could be incorrect...

    Both plugs are installed! I was hoping this was my problem. Thanks for your suggestion. This picture shows the clearance between a 3-53 oil pump housing installed in a 2-53 block.

    John Deere 435 Diesel Oil Pressure Issues

    Mine looks fine, I did initially try and past a picture, that could have caused the funny symbols. I will try it again and see if that could be the issue. David[/img]

    Yes, I see the 1/8 pipe plug p/n 444687. It appears only one is required. Not sure, might be the problem. I will check. Thanks!

    John Deere 435 Diesel Oil Pressure Issues

    I started working and overhauling Detroit Diesel's (plus I have lots of miles in GMC and Peterbuilt trucks powered by them) when I was 17. I also worked on them in my college years (1970's), helped pay my way through college. I have always liked them except when pulling heavy loads through the...

    John Deere 435 Diesel Oil Pressure Issues

    I would be fine with 5 - 10 at idle. It is the max RPM that concerns me. I know from past experience that 20 lbs at max RPM is adequate, however I wanted more on a fresh rebuild knowing it would decrease with time and wear. What kind of oil pressure do you see at max RPM?

    John Deere 435 Diesel Oil Pressure Issues

    I have a John Deere 435 Diesel with a Detroit 2-53 engine. I have owned it for several years. This is my second overhaul. I overhauled the engine about 8 years ago. We use it all summer long with a 8 ft finish mower. We mow lots of acreage. I also do some tractor pulling and have upgraded...

    You governor weight retainer ring has failed. The pump will need to be rebuilt. Fairly easy fix, however if you keep running it you will end up having to replace "hard parts" related to the governor assembly.

    John Deere 435 GM Diesel 3pt Hitch

    Does anyone know if John Deere ever made a stabilizer kit for the 3pt hitch? I use my 435 to pull a Woods RD8400 (7ft) finish mower and would like to limit the mower from swinging back and forth on slopes.
