    Of course your right but the urge to do just another few minutes on it before more bad weather set in was strong. Also I'm thinking that I need to get at least the head cover off and pan dropped so I can see where the leak is or is not coming from during the pressure test. Doing the test...

    Was spreading large dirt pile from tree/brush burn with D31s16 and stopped for 15 minutes. Then stated again and it cranked easily. After 10 minutes I sensed a slight laboring onset and shut it down. When I shut it down it did not "diesel" a little like it normally does. Instead the engine...

    D31 sat for past couple years. When I started it a few weeks ago oil squirted from oil cooler which turned out to be cracked (winter freeze?) since I did not drain it or the radiator when I parked it last. Got the oil cooler fixed and now I see this pink stuff coming off the head when I took...

    THanks for the parts reference. I've never been into a trany before so I guess I should get a shop manual. Any suggestions where I could get one? I'm thinking one of those bits got sucked into the pump clogging thing up.

    I drained the trans and pulled out the screen/filter casing thinking the filter might be clogged but there was not a filter/screen in it. The casing had some sludge and bits of what looks like a clutch plate as can be seen in the attached pics. I have not had a 2nd gear since I owned it for...

    1978 Komatsu D31s16 was working fine then when I went from reverse to forward nothing happened for about 3 sec but I could hear something like a pump or clutch trying to engage. Then it slowly started moving but no forward progress when I tried to turn . Went to reverse and same thing happened...

    How to bleed fuel Pump

    Cool idea Hutch. I often have a tank of air with me for various reasons and so this is yet another reason to add on board air to my truck.

    How to bleed fuel Pump

    Thanks folks. Great info. I look forward to trying to bleed and start it today with freshly charged batteries (again) Stray Cat- What did you mean by "and keep pumping with the fuel injection pump in the shut off position" ? The only fuel shut off I know of is the one coming out of the...

    How to bleed fuel Pump

    Ran my Komatsu D31s16 loader out of fuel and now can't get it started. Wore out freshly charged batteries today trying to start it. Hope I just need to bleed the fuel pump but not sure what's what on the fuel pump. Below are links to a couple pics of the fuel pump. The fuel line comes into...

    Komatsu D31 Track Loader Air Flow backwards after engine rebuild?

    Yes. I checked and it appears to be installed correctly and is fan belt driven. I guess that is to keep the radiator fins from clogging up with dirt. Thanks for the feedback

    Komatsu D31 Track Loader Air Flow backwards after engine rebuild?

    I got my D31 back from an engine rebuild a few months ago and just noticed the fan is blowing the air out the front of the machine. It doesn't make sense to me that you would want to blow hot engine air across the radiator and I'm pretty sure it wasn't doing that before. I haven't looked yet...

    Looking for a new track loader

    I'm looking for a new track loader (not used and not compact) in the 70hp/14000lb range. Is Cat the only one that still make any under 100hp? Any recommendations?

    Sorry Darin, but I thought I was waiting to hear from you. After you told me the crank you had was to short of a throw you said you were checking to see if you could find a rebuild kit with just the other parts I needed. I have a couple more leads but I'm still looking for a crank. Do I still...
