What dozer would you buy

Having a HD5G I can say for it's time it was fine, at same time i had a HD4 loader - lighter - faster - more problems ,  HD5B not enough power for jobs I did with 9' blade - underpowered. 

y HD5 always did what I wanted it to do, have never owned any others to compare.

HD11 with blade is great for around the farm. Piles the manure from the cowyard fast.

AC Fleet

Nitpick.  The correct Allis grader designation is "Forty Five" if it has the supercharged Buda, "45" if it has the 10000 direct injection.  (e.g Parts Lists, Form TPL-272 B and Form TPL-411 Australian edition)

The supercharger might look like a GM but it was made by Sweitzer - or at least that is what the tag on ours says.  It is cast iron and heavy.

Both dozer and grader engines were 516 CID but the supercharger grader engine (ADS 516) has a longer front bearing on the camshaft and various differences around the timing cover area to do with the supercharger drive.  I don't know if the longer bearing was continued when Allis started driving the cooling fan off that pulley.

We've put a "Forty Five" back into action - hence the parts books!  There are some posts earlier here around that project.  And I agree that they are pretty effective and adequate for our ranch needs.

Just passing on things I learned on the front line of keeping them going.

Some days the retreat line might be preferable but then it would be scrap.

No way if you can make Scotchenomics work.  Ours has already payed for what we did.

And for irreverent comment

I invited the bloke who was driving it when it blew up to come and have a listen.  He did, then turned to me and said "It will see you out".

Kindof wish Allis had never made the merge with Fiat and survived the bad times.  If they had I would go for a improved version WITH Allis or Cummins engine of the FL10 or FL14 series loaders, would have been hard to beat.  HD11 and 11b or 10b would be good choices on straight blade machines.

Yes Ian the FL10 series used the same but slightly metric dimension rails as the old HD11 and my 7G, cannot find any of that size now. 7" pitch 177.8mm

To add to the confusion ,Cat D5 track is 6.91 inches. Cat has weld on sprocket ring to retro fit the older D6 to us this same chain with bolt on segments. So maybe sprocket diameter of the AC/Fiat machines is close enough you could convert to bolt on segments and chain that still being made. 


Back to topic
I have run a bunch of HD5s and always liked them. Have not been on the other small machines,but bigger is generally better with dozers.

That Case chain does sound close.  I found the Case specs on a Case site.  Similar basic layout to FA 10 with more lower rollers.

Some more specs for the thought mill from my service manual.

FA 10 with 40 link chains (loaders and FA 10B) had 6 lower rollers and 2 carrier rollers standard.  Original FA 10 was 38, 5 and 1, with the option of a "Lungo" that was the same as the loader - ours has this option.

They have 2-piece sprocket segments.  Pitch circle 790 mm, 28 teeth, 69 - 70 mm face width.   The bolting flange of the sprocket is offset to match to frame alignment

Front Idler diameter is 660 mm (over wear diameter),  70 mm across centre locating rim, (carrier roller 75 - 76 mm across locating rims).

Track roller is 195 mm over wear surface diameter and 163 - 165 mm wide between outer rims.

Link pitch 176 mm, height 103 mm.  Bush OD 58 mm.

Rails (measured on dozer) about 160 mm wide across outers and about 81.5 mm between inners

Hope this helps

John,

For a while what I presume was the Fiat Allis crawlers were sold in other parts of the world as New Holland after the FA brand disappeared.  Up to about the 30 models as I recall. Weren't sold in Oz that I heard of.

With a "coldie" in hand i went out to look at our FA 10.

Seems to me that that Case 1659 won't have lower rollers that are smaller by much,  So with 8 it ought to have about 44 track links?

And got an idea for another post here, which is in the "You to guess and me to know" category for the moment.  More when it has gelled.

you need that dozer Les...you could shave off the ground where yer gonna drill a well!
