I have acquired an 8010 fwa in a sad state of disrepair. The story as we received it is, “that it leaked water in the pistons from the spark plug holes”. That should set the tone for what I am working with….its clearly stuck! The rain cap is missing and coolant hoses are off the radiator and it is completely unbolted and loose in the chassis. Injector lines are just sitting in place and all injector hold down hardware is missing. We started disassemble and shows very little water intrusion from intake or exhaust through the turbo. We drained 7 gallons of water out of the oil pan and the pan itself is bulged out like a football. We noticed a soft plug is missing from rh side of the block just ahead of the block heater, interesting! Removed valve cover and found rust on the front rockers but not as bad as expected. Removed head and found cylinders were completely rusted. All 6. It didn’t appear the injector were removed and set back in but can’t know for sure as the previous owner passed away 2 weeks after we got the tractor so no more history can be obtained but I doubt he would have been much! When we unhooked heater hoses it appeared to be only water in the system and the way everything in the coolant system is rusted up. Attempted to drain the oil cooler and the soft plug cover on the bottom fell off. Most likely from being frozen. Im pretty sure we will have to remove the block for cleaning and inspection. Took the block off plate for the cam driven fuel pump and the cam is pretty rusted so that will need replacement. Will be sending the injection pump off to ed for repair as it had sat open too.

So a couple questions I have is….is the missing soft plug caused by frozen coolant? Where do I inspect for cracks in the block if it was frozen solid? We have a couple different engine options to swap but the blocks aren’t the same casting number. One is a 77 M2 and the others are 79 L2. I know front plate needs change and various coolers and accessories to make work but are they viable candidates for the swap?

Ugh….what have I gotten myself into?

Not described, but I'm assuming this engine is new enough to have the M-100 Bosch inj pump and the eng oil cooler is in the left/ oil filter side ?? Only was ever around one of those oil coolers and yes I'd say it is junk but don't know that for sure. The 79 L-2 engine would have a block new enough to have been in the 7020 time period, so it would be fine. 77 M2 would work but not be structurally as heavy. I don't think I'd waste my time cleaning the block and having it magnafluxed for cracks. I've never had a 2000 series block ever frozen so I don't know where to look. I don't think it can be trusted if it has straight H2O in it.

The tractor has an American Bosch pump on it and the cooler is between the filters on the left side of the engine. The spare engines all have the same casting numbers but it's different than the tractor. The m is a 2900 and the L are 649t but other than the turbo arrangement they are pretty much the same.

I was never around a 301 engine with the M100 Bosch, so I don't know if the reliability of the pump was any better than the ones on the 426 engines. If it was mine,I would seriously consider putting the Rossa system on it. I don't know if there was any big advantage of the newer style oil cooler either. Maybe you want to keep it as original as possible? It's usually, finding a decent, usable head that can be the hardest part of retrofitting the engines. The copper tube injector sleeves can be troublesome. And, I sure hope that the rest of the tractor is in better shape than the engine.

I agree with Lynn, if have Roosa powered 301 from a combine, I'd keep that fuel system and have that properly rebuilt and set up for use in a tractor. That would make a nice 8010, or if you didn't have any 301 parts to fix it, that would be a nice tractor to 5.9 swap, as much as I hate to say it lmao!

I hope you didn't pay much for it. FWA itself could be a money pit.

Is it a Power Shift ?? because 8010 PST's are weaker than an 8030-50-70. They cheapened one planetary inside the tranny. Now if you use 6th gear all the time to do your heavy work, the Cummins would be OK fine.

Hey Doc, can you tell us witch planetary is weaker in the 8010 PST than the three bigger 8000, and would that planetary out of a 7045 PST fit in a 8010 PST ? Thanks Dave

Parts from any 7000 series PST should fit when it comes to the planetary's. The one they changed went from 4 planet gears to 3 planet gears, as they figured 110 HP could live but 130 HP and up could not.

We paid way too much for what it was and now it’s looking really bad! Unfortunately with where we are at it needs to be fixed.

It is a power shift and will primarily be used for a loader tractor to move bales but not feed lot work.

If using the Roosa pump the front plate needs to be the combine plate? Then have to build angle brackets for the frame rails? Or will it attach to the ambac pump plate? How far off will the 130?hp combine pump be off from the tractor? The quantity of pump work in my future may not financially allow a resetting at this time, for loader work only!

We have kinda strayed off of the original post subject, but I have a couple of questions on the 8010. Were the lighter power shift parts really a cost saver if the parts weren't readily available off the shelf? Did they have to redesign and make new parts just for the 8010? That doesn't sound real efficient to me. Was the Bosch system a cost saver or was that more for emissions? Also, was a new oil cooler design needed? Maybe that oil cooler had been in use on some other products that I'm unaware of.

Good question on the special planetary carrier. In the end, it was probably a wash. I can't imagine the 8010 sales were even half of what an 8030 was. The M-100 Bosch may have been the Harvey plants attempt to buy one brand instead of two, saving money. But I think that M-100 Bosch was bulky enough, the old style 7010-7020 oil cooler couldn't be used, so they designed a new one for the left side.

Stanadyne pump front plate will require a couple of lengths of angle iron to be be bolted inside the frame rails. 130 HP flywheel will yield 107 to 110 PTO HP....the same.

I've only seen one 301 engine with the M100 and that was in an M3 combine. I would think that the number of engines produced with those pieces are very few.
