1980’s FA 11b junk?

MINNPAR is about the best access to what is available, CNH dealers that will go thru the effort CAN access some residuals still in system but these tractors are now forty plus years old with parts sourcing depleting as we speak.  Rails and UC is Unobtanium USA now, can Mod it for Cat Rollers and 6.91 Pitch Cat rails but is a Job.  Engine parts trans parts, finals, just not much that has not been picked over.  If would have one and have to got to that level of modification would be better off buying a old Cat.

Been there done that and spent as much keeping it moving than had I bought a parts common machine in better shape to start.

i agree! Look at the left side how the blade is attached to the UC frame... looks like the IH blade is smaller on that pin.

Buy a Cat if you have work to do! and parts are available! 

[QUOTE=farmtoybuilder]Buy a Cat if you have work to do! and parts are available! Best advice on this thread!!! 

You will be tearing down the Cat to do major servicing just as you would with any brand of crawler, so make sure you get all the specialized hydraulic pullers necessary to that with Cat tractors unless you want to pay the Cat agent techs to do it for you. You don't need all that tooling to service the Allis tractor. You will learn from expense and experience that the tractor you photographed is not 'JUNK' at all. There are a number of us on here that run them, and we did not arrive with the last shower of rain. We have many thousands of hours both running and wrenching on crawlers. I think you picked the wrong forum to use the word junk with them. Go back to the forum that told you they were junk, and get 'expert' advise there on what you should buy.

I was asking if they were junk. Maybe you failed to notice the “?” on this thread. Notice most the discussion is about parts and how hard they are to find. I think we have addressed only that. Pretty sure no one has come out and said they were/are junk. 

Not so much 'Junk' as Job Security maybe?

As to the carrier roller- these machines had a weakness there- shafts on the carrier rollers were too small and subject to bending in tough conditions, especially if there was mud or debris packing in the tracks to the point where the track release would be needed.  There have been various mods to deal with this problem, most commonly re-working the tower to take a Cat D5 roller (heavier shaft).  Sadly parts are getting scarce, but only makes it easier for the buyer to make a deal.

Is that your cab heater the black hose on the bonnet ?

DMiller wrote: Sorry Mac as to being negative on here, but dealt with close to eight years of fussing, floundering, modifying pieces and parts salvaging used stuff where the stockpiles are dwindling here.  Rails Rollers, pins bushings and other hard parts are just becoming non existent in the states.  Can have pieces freighted in from Asia or EU or even AU but cost prohibitive as rates are near as much as components and the machines that use them failing across the country to be scrapped rather than salvaged as rode out slick. No Fuel injection pieces for AMBAC PSB, tender old systems that are becoming ever more age frail do fail and no place to acquire adequate pieces to fix here.  I have been educated to pick my battles, with FA in the US is a problem Orphan anymore.

My uncle had an early B that had the  International Harvester 100 series pump used on the 300 and 400 series diesel engines.

The black hose is my "redneck heater"- made out of misc. plumbing parts

All may become a moot point as our elected officials change here.  EPA is set to gain a decisive if not controlling aspect to what machines are allowed to stay serviceable due to emissions levels.  The 'New' camp is more entuned to CARB guidelines as to rule making for Older machinery.

looks like your using it for what id want to use it for!!
