7G, hoping for the best

Decided was time, brought Allis up from the barn and I believe the old gal is ready for surgery.
Multiple concerns to be address. First swap transmissions to the one I have resealed, finish out some small hydraulic lines changes, inspect the torque converter drive for the Trans pump and get as much right as possible. Validate that works well, next move to dropping hardnose, pull radiator, after inspect mounting points decide whether to install my spare or have this one cleaned, have new pivot bolts and sleeves for the hard nose as well going to install the one off the spare parts tractor(Sweeps cage will follow). To follow with rails off, get the tractor elevated, cribbed up satisfactorily and POSSIBLY drop right truck to access the sprocket and drive shaft that is wobbled to death. Will be dragging as many spares off the donor as get to the process including rails. Donor also has rail guides which will come off one way or another and be transplanted to my machine, all sprocket and idler guards are going BACK on. Additionally with hard nose off will be installing the Alternator I purchased some time back, already machined the mount from the donor to swing it in place of the generator, 24V but Neg. Grd. this time, will also get all new cabling for that install.
Have a decent straight hood off the donor with the hood mounted stack, will be rebuilding the exhaust elbow after the turbo and aligning to feed the exhaust up thru that style stack. Thinking 3" Pipe weld Short Radius 90 and see what I will need for pipe with flange to get the angles correct.   Should all these work out, may actually have a pretty sweet old loader.

Will be slow and methodical on these fixes, was busy trying to excavate and build a house for last set of repairs, now have some time and a decent shop to work in on it.

It looks like you have removed the brush cab/Roll cage. I always liked to raise the loader arms and chain them up to the brush cab. It gives you a whole lot more room to work on the motor/ radiator. The last hd6g I had, I could not get the hinge bolts out of the hard nose. When you put the radiator back in, make double sure there are no loose parts left laying on top of or around the motor. Radiator cores are experience. Speaking from experience. Have fun with it. Bee careful.

Short work day today, all the retirees from my old Plant Crew had breakfast and Bull session, almost noon before home. Disassembly has begun. Loads of structural in the way now removed, next will be decel and brakes, hydraulics off converter.

not many will take on something like this, even fewer know how all this stuff works

Really a simple transmission, bronze friction discs hardly ever wear, separators are steel and show little wear, seals internally are oddball, if my magic concoction functions this trans should outlive the 344.

Lots of IFS MAYBES, but pretty well dotted the Is and Crossed the Ts to get this far, if anything can help the next jamoke that finds one of these still running yet weak.

Other than that is a Old Mechanic that is frustrated with new Sh!t that cannot be repaired, sees a little glimmer in a forty five year old machine that still works as hard as he does, just trying to extend that life so ever little bit.

Moment of truth day, busted my hump and a few knuckles getting the machine functional enough to test operate and leak check. Filled trans oil and lit it up, sat a long time looking things over then cycled the range shifter seemed fine. Out of the shop Lo Forward was solid, shifted to Hi with a hesitation of some kind, then down the drive just looking it over. Stopped and slipped into lo reverse then stepped into hi reverse, all of a sudden stopped moving.

Sat and worked quadrant control, had Lo Reverse, locks up in Hi rev or any forward gear, something hard failed in box, backed all the way back up hill and into shop, still no leakage noted. At this point will replace seals in second trans, see what it feels like then swap back to it, will tear into this box once that one is confirmed functional.

Not too important but also part of requirements in a change out. Was within spec when pulled this trans and installed the donor back a few years ago. Did not have Lo Rev when pulled this one where suspected was just the seals but am scratching head on this currently as to the jam up.

Steering on these is rough if keep the boost up on the brakes, my own is backed nearly full off on suggestion form Down Under and helped. Are you getting clutch disengage? Are the brakes up on adjust? Tighten snug then back off two full turns otherwise will drag and heat up and yes pedal will be close to floor on apply. Seems pedal stroke was for prior style machines and the boosted power steering just got added on.   Brakes and hand clutches work from the same pump, under the injection pump as I am certain you are aware.

Trans number Two

Got it arranged for tear down and managed to get Upper Shaft apart to reseal it. Will reassemble that one in AM and them reseal Lower, the two done then will clean up case and end plate begin reassemble.

Well is back together, time to sweep up and start pulling the failed box. Already have the system drained.

Is now the MFA Brand. Been very satisfied with their products at least in this AC

At least the 180 is back up and Kicking(KNOCKING hard on my wooden head). Replacement starter arrived last night, wife had Doc and store run this morning so I went along(Lumper), got home and installed starter. Also started charging batteries, first one was low at 12.6 but charged right nice to 13.2 when done, second one NOT so good and likely the cause of starter winding over amp cook off. Started out 12.0, was on charge about half an hour and bumping 13.2 when the charger went to safe shut down, voltage dropped to 9.7, bad cell. BACK to auto parts store, replaced that one and all is good.

Got back blade on for "Pretty" duty(Darn Shameless and that Machine) are predicted for anywhere from 3-6" of the White Stuff Sunday into Monday.
