7G Never stops amazing me

I managed to get the steering oil pump to prime, yesterday took the tube off at the pump and filled the inlet with ATF, was working fine then this morning after almost two hours of pretty stiff use the left brake pedal went to the floor.  All external linkages showed good, went to the adjuster and all it does is spin.  Time to tear that down and see what's up.

You were correct Mac, left lower band shoe had the adjuster ear section broken off.  Bands looked like almost new too!  I am well on the tear down road, have the fuel tank off, the batteries out and the box coming off, already have the butchered cab guard off, I am going to pull the right side as well as I think I found part of the cause and my steering issues, as I had the left clutch cover off and the lines all removed I hit the clutch application port with air, the seal at the piston is completely blown, won't hold a least little bit of anything, unhooked the right side, will hold air for a moment then gone and whistling in the case, so it too is leaking.  Got on Minnpars site, had the seals and some other odds and ends I needed here, Chartrand tractor has several later model 7G's and Willie said he has one with good bands(recent replacement prior to ending up in yard) so will retrieve them for me.  All should be here by Friday next week giving me time for tear down if I should need anything else.  Jacking and blocking starts tomorrow, the removal of the clutches by tuesday, will have to rig a temporary lift eye to the left side clutch as the brake band ear is gone and nothing to lift from.  Photos to come.

Not enough space in the case for the pivot points to pass the drum, you also use the bands to lift the clutch drum out.  I have the clutches and the bands out now, I will also have to replace the left bevel gear drive flange/hub as it is cracked between all the release hub holes.

Site won't allow more than two photos

might be wise to do the final with the turning clutch out to make it easier to turn the gear when you need to. looks like you are into it pretty heavy. i did not realize that they were wet clutches. did the track master pins come out ok or did you struggle. just got one side of my hd5 apart a week ago and it was about a 2 hour job to drive out the pin. keep up the good work and the picks. i am glad to see misery loves company when working on these old girls.

Don,t worry your far from alone it these 1 step forward, 3steps backward dances with old crawlers. Not just allis either, caterpillars have them, cyrus Hs creations we, re told have 4 steps backwards   At least you have a nice dry shed !

Willie at Chartrand got me taken care of for brakes, look almost new, I am changing both sides while down.  The seals arrived from Minnpar with the gaskets they had, they are in, the rest awaits time, probably Monday at the earliest to get back on it.  I am considering weld beef-up of the stationary link pivot on the brakes, my old bands showed wear from the shoes rocking backward against them.  Willie sent a better one of these(all he had left) and I may weld up and dress back one of the old ones to match.
