7G, hoping for the best

I am Sluffing off today, 20# sledge liked to work me to hell and gone!! Still have to deal with the right Master pin as Stopped moving with close to an inch to go yet. Just Wore me OUT!!

MAYBE Back on it Monday after liberally apply alcohol for Covid-19 Protection internally!!!

Have a late eruption seal on torque output to work on then work to get it outside, then can start the Cage conversion and straightening actions for Rear Sprocket Guards. Closing in on that Brass Ring completion as far as I want to go.

Keep on oiling it, and then go do something with the machine!  Then try whacking some more, till it moves in...

You keep it up and you will have to move some dirt

Glad to see that this machine is going back into action again. I have heard from more than one owner/operator that these machines were top shelf in their time. Before We bought our first AC crawler, I was told by a gentleman that owned a large fleet of yellow crawlers quote "In a lot of ways, the HD-6 is a better tractor than its yellow competition". My only wish is that we had a source for spare parts.This loader is an improved HD6G.

Shop is a WEE Bit tight with cage and tractor both indoors, better than working wet. or soon to be COLD!!

What I inherited off the donor is staying for now. Do not have time nor patience to gas axe all the grousers and know full well the issues on loader, NO turns with loaded bucket, softer on controls to make turns, can be a fine balance act but doable. Old rails and slick shoes in the barn, quite possibly if get gumption will add two 5/8 rerod bars to those and swap shoes as many of these are pretty sad on the toe or heels.

Gonna start in rain again tomorrow, got the cage set today, rear mounts will have to be different. Will set Stop blocks on front tubes first then start on backs, also have to drop trans pan yet ONE MORE TIME, snail trailed backing it back in.

Fronts are set, 1/2" Steel pipe sleeve thru the holes, down stops welded on insert pipes, 1/2" gr 8 bolts with custom conformal spacers over pipe inserts.




And found that Cussed trans leak FINALLY, was one of the Reverse shift oil tubes, last two threads are SNUG but turned until stopped and oil stopped. Trans belly pan BACK on and done for day as rain started again, no outside getting bucket back on.

Well six months off and on of farting around with Old Machinery!!. Spent two days hammering and bending the rear shields back into some form of Round and inside the dimensions of the rails. NOT perfect but better, Had to cut away the ears for the truck frame mounts as just TOO severely mangled but did save One, used angle iron for replacements. Old gal is not especially Purdy, she is homely as a cardboard box but is mechanically as complete as I am going to go. Was considering a Dupont Overhaul but this is still a work tractor so not in the cards.

My home spun shield reformer and the net results..





As soon as dries down some, time to put old Fat Allis back to work.

Track Tensioner difference is Phenomenal. Only roughly 1/4" of pistons exposed now, were at least 1 1/2" exposed on old rails.

Relatively short, part timing, hobby work. Old gal still has some seeps and minor leaks, not going to go completely thru those as some are lack of parts others are required time to repair for a seepage leak is excessive. Converter output seal does not hold as shaft is worn, I am thinking too much play(Noticeable) and requires engine/converter removal to get at adequately or to swap converter. Oil is pretty cheap for the little it leaks off. Mostly a mess concern not function.

Meant to add, looks like the typical Demorat convention, everything at a standstill and Sh!t everywhere!!!

I should have some very good used  plates and discs 

Good afternoon- new member here. I have a fair amount of crawler experience with my JD crawlers but I am getting ready to join the "orange crawler" club with a 7G-B (is it still considered an orange machine if a Fiat-Allis?). 

I assembled the Reverse Clutch pack today, and found what I had missed. A .250 x.200 dowel, was NOT in the pack when disassembled, know that as fact, is in it now, short piece of drill rod.






That would allow the Shaft end opposite application piston to roll with the clutches, NOT hold as clutches applied.
