    Swapping engines: rebuilt fx140 HO for a blown FX140

    Hello, I've got a 2004 FX140 I bought with a blown/non-buildable engine.

    I purchased a SBT rebuilt FX140 HO engine and was in the process of installing because many of the parts are interchangeable. I now know the PTO Gear reduction cover and oil pump are not the same, so I'm going to buy one from eBay. My question is if I can use the same oil cooler? Parts catalogs have a different part number, but the only difference shown in the schematics is a different plate on the bottom of the upper filler tank. I've shaded the only difference in yellow. Can I reuse my FX140 Oil Cooler, or do I need to buy a HO oil cooler too to match the change in oil pump? I'd assume the HO is pumping a larger oil flow, but then the hoses carrying the oil are the same size, flow can only be increased if the pressure is increased also.

    I'm not sure what that different plate would have to do with anything really.

    Kinda what I thought but I didn’t want to jeopardize oil flow and my new engine.
