Had a little time yesterday morning, as my car was getting transmission lines changed(Special Tool I will NOT buy) and seeing as the stack is Not 4" but 4.250 ID decided to see if could salvage the OE Unit. Knocked the dents and dings out then set it and got to constructing a New Clamp. Simple structure just galvanized 1" strap 1/8" material. PI R Squared (Round if you like Pie) added a Inch for each end then added .250 for a Ear on one end and drilled the 3/8" hole then folded and proceeded to hand roll until fit. Minor tweaks and VOILA!

And another days worth. Local Carwash at Sunrise, cleaned Valve Cover, Belly Pan, then pulled radiator. It lost at LEAST 40# yet still not clean enough just easier to handle. MORE Diesel and then MORE Soap and Water!! Later.

Valve cover swap out completed, Belly pan surgery well under way. Yesterday got wash HERE completed then installed Grill and Chin.




Still have to add bolting straps and straighten the access cover but gets closer

Final result on Belly pan looks decent. Then got busy set old monster on stands, Rear is on a 19" tall section of 8" Square Pipe, 1/4" wall, may as yet raise nose a little more. For now rails are off, ground out the welds where I had secured the old Master pins, eyes just so beaten out would not hold further, Measure 28.600+/- a little across four links, essentially 90% done and done in, bushings to sprocket not worn bad just pin to bushing and REALLY Snaky. One choice bit to try is removal of right truck to replace the right final shaft and sprocket, last roller is a interference mount to sprocket so cannot just cut away the tail of truck to weld back on. All rollers look and feel good, Idlers roll smooth and no noises.

SNAKE!!!


Darn near to the point of dropping the truck assembly, Nut is off, all but one and previously loosened cross bar bolt are out and only lack pulling loader frame bolt and four bolts retaining rear truck arm bushing to lower it to the ground. Buddy and I spoke, he is going to lend me a 60T hollow piston hydraulic cylinder, will make a stud for pulling, 1.250 12 tpi unknown length until get Cylinder and build a stand off pipe section.




With that need to get track adjuster seals and set these up

Chalk another win up to the 7G, 30T on a hand made pulling stud, stud hanging right in there and ZERO movement even heated then Massaged with a 10#, NADA.

Reverting to the cut and weld method, Hate to even think of it but then gotta do what gotta do and this final HAS to come out.



Got One rail out of the way, palletized for later movement, and got the rear roller out of the way for hacking the truck tail off. Chalk mark is centerline of Truck roller bolting just reference.

Actually have access to three shaft/sprocket assemblies. One I bought from Chartrand in IL years ago, been sitting awaiting this time, then ended up purchasing the Donor both rear shafts are still in it. Sprockets are all three slim and pointy where even as notched the ring off my tractor is in better shape.

Got outer support apart, not socked to see issues. Housing itself was bent(Salvage yard Heavy Handed Goon by sledge marks. Went to donor derelict recovered those two, seals still good in both, one had been loose awhile and bearing junk, the other seemed passable so disassembled to repack and pits on inner rollers. Salvaged bearing off original, smooth and no marks, salvaged housing and seal face off donor tractor, all packed and awaiting the seal steel glue to set so can install. Also had to salvage a few shims from the donor as several crumbled to dust on removal on running tractor.

Some days though Merv Some Days!! Have been those times when considered best place the machine could have gone was Scrapper. Been a project and process, may give some a clue as to what they too can walk into.

You know the adage "Tits Tyres Tracks", all cost money!!

Moved to other end today as struck out at Donor until can get this one moving to lift the nose of the chassis at the barn. Roller mounting bolts are NOT going to come easy. Have two MAYBE IF POSSIBLY Salvageable bottom rollers. Right sprocket shaft is junk, left is not much better at the outer support bearing seal surfaces, been Dry WAY too long.

Did get track tensioner seals placed and got as far as could with Left Idler. Right side going to be MORE Challenging.

Managed to get four more bolting blocks cleaned up to attach the right side rock guards. Ended up taking them to my mill and cutting the bolts out to the thread line from the bottom, then they just collapsed and unscrewed as twisted them. Working on side brackets tomorrow and maybe the spoil shields. Did figure out these were these not for looks or even to protect the Idler but to keep the materials from damaging the shaft seals, is no protection for the seals without the shields. 7G-b same shields and as many or more of them in the yards.

Was thinking on the two I have last night.

My first buy the idlers and rollers all inspect to 70-80% value, sprockets even the damaged one had a full 1/4" at tooth tips. Rails were so slop junked as to walk off anytime got the least slack. Second tractor, all the lower rollers junk, both idlers absolutely worthless either for bearings or wear, sprockets were worn to sharp point but rails were nearly New, engine block been allowed to freeze and bust. Makes NO Sense.

Photo of the replacement rails under the tractor show a little curvature, is all the wear they have internally.

yes is often the case Dave; a man ends up making one good machine out of 2 of them. But is a hell of alot of work; and a man needs alot of time patience and knowlege, and deep pockets to do it all !
Trouble is often we are too busy working trying to make some $$ to get ahead in life; that the time and effort to ressurect machinery becomes abit daunting !
Is mighty good once you,ve got there; but the journey there is only for the brave; or foolish  lol.
Have got a HD11ep and HD6ep that fall into these catagorys; were both machnes i saved from the crematorium.  Thing is if i hadn,t saved them, a man would kick himself for not saving them !
