Allis Chalmers HD21 - Starting and working

[@jerryhammack1318]

I remember my great uncle Clifford Sloan hauling these to a mine in the early to mid 70s . He was the only heavy equipment hauler in the area at the time. He ran a cab over Peterbuilt . When he got his rig repainted the paintshop screwed him he was colorblind. It was supposed to have been blue. They painted it bright purple. He got so many good comments on that rig he kept the purple! He was well-known over the road ! You couldn't miss seeing that big bright purple Peterbuilt! Hauling huge loads allover the south west! Miss those hd 21s and that purple Pete! Bless you uncle Frank ! R.i.p.

I love old iron. Even though new machines are more user friendly and comfortable, they will never have the style and longevity of old equipment.. That Allis Chalmers could sit for 15 years untouched.. New batts, and a whiff of either. Shes working again.. Beautiful..

Love the sound of an AC engine. Great vid.

A great dozer doing a great job! Allis Chalmers 👍

[@sequoyah59]

Ran one of these as a ripper tractor in the summer of '76 until the torque converter went out. Hauled it to OKC and it wiped out the right rear wheel bearing on my truck.

Smooth and fast for it’s age. Not sure what year but it has direct electric start so 1970 or so?

[@french_machinery_channel]

1958, but electric start has been added.

[@MegaBulldog74]

All Allis-Chalmers crawler tractors were direct electric start.

[@marcostelzer8737]

Saugeil !!!

[@stovepipe9er]

Do you have a clutch lever for gear changes? Is there a foot throttle?

[@krb5292]

To answer your questions, yes, there is a clutch lever. The throttle is a hand one. There are many videos on KZbin about dozer operation.

[@gary24752]

Why did they go out of business?

[@juanasanelli6831]

SE vendio la parte de maquinaria agricola y vial a FIAT y pasaron a producir Fiat allis ...Luego al integrar el grupo CASE New Holland ( Fiat) el bulldozer que era Allis Chalmers , Fiat Allis , se vende con el nombre NEW Holland ( Y no se le parece EN NADA

[@chun3720]

Is that the supercharged or turbo model engine?

[@RJ1999x]

Turbo

[@Bushguyrocks]

Starts it up and drives away immediately. No warm up!

[@french_machinery_channel]

Motor is hot !

[@jimmotormedic]

Yes it was warm. Cold diesels don't blow black smoke. It would have been blue or grey. First thing I noticed. AC made some good machines back in the day.

[@jaypunch7462]

What year is that is that beautiful old iron -- '60-65?

[@brycejcox]

Jay Punch 1958

[@rnico4339]

Il pousse le vieux Bill !il a était restaurer ou c est sont état de origine??

[@reallyslowcustom2514]

Ok do the hd21 have good finals drives in them

[@RJ1999x]

Yes

[@rogert7817]

😮 The drives themselves were good but the inspection port was a poor design. It was located in a stem that stuck out off the back of the finals. On my machine a rock got picked up by the track and came around and broke the stem off, allowing dirt and stones to get into the final gears which did about $8000 worth of damage. Not a good day.
