Jailguard

Well, the backhoe is still sitting where it was rolled to (via skidsteer and tractor). Obviously the transmission is sufficiently disconnected from the engine. About 3 weeks ago, I noticed the fluid level had dropped in the injection chambers. I thought the engine was completely filled with Marvel Mystery Oil. I then managed to pour another 96 oz. of MMO down the injector ports. I then took the valve cover off, saw a small amount of rust and sprayed PB blaster in there. There was no gasket on the valve cover, just a shoddy tore up bead of silicone. I'll be heading up to it tomorrow and will update you all on any progress. I plan on turning that engine over tomorrow!

Unfortunately, I do not. So I might only have 8" of clearance under the best of circumstances.

Good morning all. Well it appears everyone else was correct. I was wrong. The property owner was able to move the backhoe to a another location on his property using a Bobcat and another tractor. He said it rolled rather freely. Several of you have suggested I drop the pan to see what I can see. The biggest problem is where this is located is very wet ground and 3 of the tires continuously hold air the 4th tire needs to be refilled every day. It is slowly sinking. I have minimal area to work underneath this backhoe. I'm not a mechanic, but I can fix most things. Whatever I end up doing is probably gonna have to be done in this field. Any infinite wisdom is most surely appreciated understanding my limitations due to location mainly.

Ok, Thanks. However I disagree. One of us is right, I'll let you know eventually what was the problem.

Thanks Binderdan. I'm pretty sure this has the Hydrostatic transmission. In the service manual, (I have 2) it states and shows the safety switch (electric signal allows starter to get power) must be engaged. I have made it this far, my new starter engages. The problem I'm having is disengaging the hydrostatic transmission from the engine. Where dose the hydraulic pump get its power? Electric? PTO mechanical from a running engine? In the diagram, notice the hydraulic high pressure box up and to the right.

Ok guys this engine has yet to turn over for me. I think the "dump switch" i.e. the safety switch is not disengaging the engine from the transmission. The electric part of the switch is doing its job, the starter will crank...but I only get the "thud". Flywheel will not move. I hooked up the battery again today to play around a bit. Behind/under the key switch, this disentigrated (see photos) first two, looking at my manual I can't determine what it is. It looks like a starter solenoid? There are 2 other "blocks" that were disentigrated too, they look like some type of voltage regulator. You can one of them to the left of the "? Starter solenoid?" The third picture is some type of switch, not sure what switch and the other end of the red wire (heading to the front of the tractor it is not attached to anything. Don't see where is would go either. Don't see it in my electric schematic in my manual either.

Well at this point, it's been given to me. I'm only in it about $650 and about 30 hours, so I'll keep going until I get it.

Hey Guys. Need more guidance, 3500A will still not move. I have soaked this engine with Marvel Mystery Oil, PB blaster diesel mix. I have tore up my "bar starter" 2 times. I have the "dump pedal " pushed down with "third hand" while trying to turn the engine over. I'm spent! I have an actual hard copy and a digital copy of service manual and owner's manual. Am I missing something?

Ok one last question (currently)! How can I tell if these are tubed (I assume they are) tires or not. I'm seeing alot of the front replacements advertised as tubeless. I know in my old trucks, you have to get a different wheel/rim to switch to tubeless. TIA!

Ok everyone. The engine seems to be locked up on this 3500A. I was surprised to find that it doesn't have glow plugs, just injectors. I pulled the injectors and filled them up with Marvel Mystery Oil, also pulled the exhaust header and did the same. Can't seem to find a way to manually turn it over. There is nothing to grab? 1/2" SOCKET....no hole no bolt. Any ideas? I tried to tooth it from the flywheel, only opening is the starter mount hole, no leverage. So the guy told me I had put enough work into it ( new starter, new fuel filter housing, new fuel filters and hours of time) I CAN JUST HAVE IT. So to ad to it being the first engine I have not easily freed and turned over, the tubes are shot in the tires. Give me some help and direction please!

Thanks Binderdan! Any idea where the stinking oil filter is located. This thing is only about 6" off the ground (front tires way low and its sunk into the ground currently), I have looked all around it, obviously in the most most common areas more, but no luck as of yet.

Ok guys, I pulled the fuel filter assemblies off. The glass bowls were chipped, cracked in different spots on both. I think you can still get replacements from yesterday's tractor and a few other places. Is there a more modern easier upgrade? What do you guys make of the photos? Something looks askew on the 2nd one (silver).

Thank you sir!

Yeah? I think I can pretty safely assume it's a D239.
