I am putting my Oliver 88 Diesel back together and noticed in my IT book it says something about timing the Oil Pump when reinstalling into the "NON Diesel" tractors. I"m assuming that since mine is a Diesel then there isn"t any of such that I need to do? It"s just a pump so I"m not sure why you would even need to?

Also,
Does anyone know why there were different diameter push rods for these tractors? The one"s mine had were bigger diameter than the one"s I found on an Identical tractor for parts. They were both 88 Diesels.

Thanks for any input.

The reason that you have to time the oil pump on spark-ignition tractors is that the oil pump gear also drives the distributor. Since there is no distributor on the Diesel, you do not have to time it.
Sorry, can't help on the pushrods...but it is not uncommon for pushrod design to get upgraded as time goes along.

That makes sense. I'm thinking on the pushrods that maybe someone just install a heavier duty one on mine. It used to be used as a pulling tractor before everyone started getting crazy with their motors and when they used to use half way stock tractors. Thanks for your input.

Original push rods were solid rods, later replacement push rods were tubelar and larger in diameter. J.
