[AT] D10/D12

[charlie hill]

If you happen to go to a carnival that has older rides, pay attention to the 
power units pulling the ride.
They are quite often Allis Chalmers units.  I forget the number designations 
of them now but the hoods,
radiator covers and gas tanks look very much like they came right off of  a 
B, C, CA or WD 45.  I love
to hear them run.  That crisp Allis Chalmers governor is just what those 
rides need for changing load
conditions.   I haven't been to a carnival in many years so I have no idea 
how many of them are still around.

If you look at the engine parts manual for the D-14 engine it is also used
for the industrial version engine.  The only difference is a different
external spring that allows it to rev several hundred RPM faster.  Who
wouldn't want that?

I wound guess the larger D-17 and its industrial equivalent would be the
same.

My mistake, they must have stamped the D10/12 engine numbers like the CA
tractors - on the left rear flange of the engine.
Could it be you've only seen replacement blocks or those with numbers hidden
under paint?
I've heard of transplanting into a D17 from Gleaners (model E maybe), that
would be the bigger 226 engine (same family as the WC/WD/WD45/D17/170). You
do need to put the tractor governor on it as part of the switch.
