HD11 tracks

The Allis/buda engine in the 11's is a low rpm engine but not that low, a 6V92 is not that much higher unless had the governor adjusted so, my buda 4 cylinder runs at 1750rpm the 6V should be governed at 1950-2000

The HD11 track pitch is 7 inchs and D6C is 8 inchs pitch and sprocket HD11  sprocket high

I've never done it, but have seen 11-B tractors converted to D5 chain, and keeping the Allis sprocket- did not appear to have any abnormal wear on sprocket.  D5 bottom and top rollers can be adapted.  Caterpillar also supplied an adapter for the sprocket to adapt to the D5 segments, part number 5S0834, not sure if they would be available.  HD11E sprocket rings can still be found, or you could go with 11-B segments, as there is an adapter ring for that as well.  D6B sprocket rim could also be used on older HD11E. (Cat # 5S4822).  I've been thinking of doing these modifications to an 11-B someday, but it's alot of money to spend on an old tractor.

Thanks Heaps, for all the input, guys.
 Yeah, HD6 Merv,     'You can take the boy out of the country  but you can't take the country out of the boy".

I had come up with the cat 6.91" arrangement as the closest.  Ive been a Kiwi now for bout 20 yrs, an the dozer I'm buying is in TN. Just dreaming of wearing out the undercarriage and the seller has a new never run rail and grouser assy taken off a D6C he'll trow in  for a couple thousand.

I may never use up the bottom of the old AC Hd11 but 'it's a thought' about those cat chains laying there. 

The re-power job with a GM 6V93 TA not at start up yet and deal hinges on that but for $5000, the old machine looks pretty sweet. I figure it'll be a supped up dozer  with the GM rated at 385HP. A bit concerned that the extra power may break the power train. Just knowin you got the power to shell it out will help to protect it but Ive picked up that the AC line was as good as any at the time it was built.

Anyone got a sprocket for HD11EP laying around?

I've got 2 new sprocket rims off an HD-11AG  s/n 10,000+...  San Diego

Henderson manufacturing will sell you new rims for about $400 each

Does anyone know where I can get sprocket bolts from. The guy I bought my machine from he welded the sprockets in place. I bought new sprockets segments with intent of using the old bolts. What he did he never did any maintenance to the machine. The segments got loose he never tightened the bolts and ran them loose. He either welded the bolts in place or replaced with the wrong size bolt and it’s wore the segment out.

Cat bolt are better than most others. Depending on dealer they are even cheaper than most others.

Ok thanks this helps was just curious as to what cat machine used the same bolt. Seen on here people talking about converting full Undercarriage to cat

My Cat dealer will find bolts by size,such as 5/8 by x long . I had a catalog from them years ago titled  ONE SAFE SOURCE  ,and have seen links to a on line variation.

sERIAL NO. IS 12202 HAS TORQUE CONVERTER ETC.

I have an HD11 ep looking for a new home This machine has been parked for about 8 or 9 years not in too bad shape . I have some photos that i could share with anyone who is interested . Machine is located on the east coast .

I have an HD 11E located in California I am going to sell.  Photos and video if you are interested.  The unit is field ready with a mounted dozer and is very tight.  I know we are a distance apart but just want to let you know it is available.  There is not ROPS and I am asking $7000.
