My Case Experimental Tractors part 2

Case A-124 Experimental Air Cooled Engine
A friend found this engine for me and brought it to me in October 2015. I spent a year trying to figure out just what model it was. I finally found an Operators manual for it and determined it is an A-124, very similar to the popular A-125 engine. Although they look alike there are actually few parts that interchange. The biggest difference is the crankshaft mounted cooling fan of the A-124 versus the overdriven belt drive fan of the A-125. It appears the crankshaft driven fan did not provide adequate cooling or possibly did not create enough air flow to keep the chaf and debris clear of the cooling fins. The new and improved A-125 engine also has 5 more horsepower.
It appears production of the A-124 engine was short lived and it is a low production engine. With the serial number of EXA-124 I believe this is an Experimental engine.
I welcome any information on the A-124 engine as I have not been able to find out much about them. I have found 2 parts books along with the owners manual.
The parts book pics in this album show the Case A 124 air cooled engine uses the same piston rings and rods as the VA series tractors. I believe the A 124 was based on the VA series engine

1944 VAC Experimental Tractor with live hydraulics.In talking with Mr Harry Klein he said that he felt that Engineering used this tractor to develop a live hydraulic kit for use on pre-eagle hitch VA series tractors.This kit was introduced in 1950. I have the factory literature for this kit.This tractor has a Prince Hydraulics Cylinder mounted underneath the torque tube and a Gresen Hydraulic Control Valve. Case likely did not have their own proprietary parts at the time this kit was developed.
This tractor also has an experimental foot throttle that never made it into production. The torque tube is also experimental.

neat info, so whats the exp foot throttle look like compared to the normal foot throttle

Nick enjoyed the information and pictures, thanks for posting, always interesting what Case was experimenting with.

Somewhere in my picture files I have a picture of an experimental VAC-300. The tin on the hood and fenders had square corners instead of the rounded tin work on the early 300s. I think it was part of J.R. Geigers collection in Lebanon, IN.

Thanks for the replies,
2 9600 the EXP VAC foot throttle is a casting and has a hinge pin like the earlier VAC foot throttle that was made from sheetmetal.
