160AX with threaded freeze plugs

[WayOffTrack]

I've seen a couple of 160AX motors with threaded freeze plugs. In addition to this the casting has some areas that are thicker, in particular the top left front side of the block. This is the spot that would mount an air compressor in post war applications, I think. Any chance these are really WW2 era motors?

If the block is stamped 160AX then it is a halftrack motor. White made similar motors for other civilian vehicles such as the 150, 250 and similar variants. Most all internal parts are the same as in the 160AX.

I’m 90% sure my engine was rebuilt in the 50’s my freeze plugs were threaded.

I haven't checked to see if the engines I have with the screw in freezes plugs also have a ww2 rebuild tag. that would prove they where manufactured during the war.
im don't know of another way to determine the year

Both of the ones I have here don't have rebuild tags on them and one of them is in an Izzy halftrack. I'll will get some pics of the casting difference and post those.

This pad behind the hose has 4 plugs. Isn't this where the air compressor mount is on the civvy motor? Still looking for a 160AX on it. There are other areas where the casting is different.

I did find a 160AX marking but it is tiny and hand stamped into the boss below the oil cooler inlet. The normal spot for the motor number is blank.

Anyone have a motor with threaded freeze plugs that DOES NOT have this boss behind the water hose?

I did determine these are post war motors provided by White for either a rebuild program or depot replacement motors. They were civilian 150A motors converted to 160AX configuration.

Do you know what was involved in the conversion?

If I understood correctly it was something to do with the crankshaft and front pulley.
