HD16 Sprockets

Sprocket liners call pigeon machine or manufacturing in garrison,
north Dakota

When working on old dozers, quoting how long you think it will take for a repair, then doubling it, is reasonable.

My neighbour commented that the segment discs for the 16DP are dished, those for the 16B are straight.  So that 16B might well be original.   And says the 16B axle is larger. 

There's a brand new set of chains for a 16A just down the road from me as well...

Here is a good thread from Redpower on this subject with a post of a Cat bulletin on welding sprockets, rollers and chain.

Is there a measurement or something I can use to check if the used sprockets are worth using? When looking at the new ones in the manual vs the ones on it I would estimate they at 60% left.

I apoligize for the pics I couldn't make them smaller....

The first one is one of the used pair I have and the 2nd one is the current ones on it. Would anyone use the used pair vs buying new?

Sorry for the late reply. I was on my machine for 6 hours yesterday, it was fun but the left sprocket is slipping under extreme turning (wont do that again in fear of wrecking something).

FWIW

I've heard this same story twice, both from Allis owners, not Cat men, bemoaning the fact that A-C didn't have the 3 gears (except the 21, which had 3 speeds).  It's all second hand information for me- I've never pushed a scraper- I just like to hear the stories.  I know lots of old Allis storytellers...

Yes Mac, the 16s had a similar upgrade to the 11s on the track with the introduction of the power shift, the hydraulic steer predated this a couple of years on the 11.  The HD11 upgrade went hydraulic steer (about 1961), then direct injection 10000 (1962) then power shift and track upgrade, (1963 or 64).  Then, to confuse matters, Allis continued to manufacture a cheaper HD11B model with the old track and dry steering clutches right up until the series B came out.  Way too many choices- they had the HD11AG as well, which some guys put dozers on because they were cheaper.  I had an older HD11ES, which was supposed to be a farm crawler (lighter guarding, no front tow hook, etc), but it had a factory dozer set up on it.
The HD16 was a very popular tractor in Saskatchewan.  I heard a story where one dealer in SK sold 40 new 16DCs in the mid sixties, then only sold 3 DPs the next year, when the DC was discontinued.  These tractors were used for small scale road building, and the DC worked great for pushing scrapers.  The DP, on the other hand, was too slow in 1st gear, and when they tried to push in high they overheated.  A-C put themselves right out of the mid sized tractor business with the 2 speed transmission.  The 11 was the same- many county machines were Allis in the old days.  That being said, the 16 was  still a very popular machine for land clearing here on the Canadian prairies, and many are still being used for that purpose on farms.  Some guys would run 11s as well, and use them on the soft ground, as they ride over much better than the 16, which tends to sink like a stone.

Anyway- for the SK gentleman-
I can get you new rings for either style of 16, PM me if interested...

There is another sprocket repair. Individual pieces of metal are welded to the wear area on the sprocket. One supplier offered a "U" shaped insert that was thin in the middle and thicker at the tip of the teeth. The repair I will be doing on my HD6G involves welding a piece of 1/8 x 3/4 x sprocket width on each side of each tooth at the wear point. I plan on doing this next spring when I change the chain.

I have never seen one in a salvage yard, but have never seen a construction equipment yard either....
