Now that oil pump is worn out!!! -pics

Re-assembling my 1928 D-serial-71371 --the oil pump gear teeth on the '28 are worn to almost half size!! - I have a pump assembly from a 1935 D that we got from Manitoba as a project tractor (story -no pictures when buying with a load of others-"just need a radiator and head and it's a running tractor" I was told -so I knew those parts were missing -when it arrived(should have taken a picture) -all four tires rotten and flat, no head, no rad, no hood, no carb, no mag -seized pistons-right piston top was cracked -all four rims are excellent - WOW -should have left it there-but there are very few parts D tractors in Ontario so I am glad we brought it here -have torn it down for parts, internal engine parts, camshaft and oil pump are excellent condition - using both parts in the '28 - set the cylinder block and pistons vertical in shop with KROWN rust control penetrating fluid sitting on top for 6 months -both pistons needed one blow with a wood block and sledge and they fell out!!!pics are of the two oil pumps sitting on my workbench. 1928 D does not have an engine oil filter.

I bought the 1928 D in 2000 -it was seized - came from Saskatchewan originally -I bought it from another guy in Ontario that had lost interest -have had it apart for 10 years - lack of time to work on it, lack of funds and waiting for the machine shop - bored and sleeved the block to standard -was at .090 over and badly pitted- there was a cam follower broken in the crankcase-must have had a stuck valve from sitting somewhere for a while and someone attempted to start the tractor -the push rod could not move so the cam follower broke -then the tractor was left to sieze since it would not start
 
the poor farmers had a bad habit of using used oil from vehicles in their tractors. just like the fuel dump it in the D, it'll burn anything. looks like this is a perfect candidate. how's the gears and stuff in rest of engine?
