I have a b7300 with a hydraulic oil cooler (it's mounted in front of the radiator) with a corroded bit at the bottom that is suddenly spraying oil. The problem is there's no replacement part available. There is an oil cooler available for the B7400 which has the same (D722) engine. Anyone know if it will fit?

Is THAT cooler the same "size" and use the same diameter hose connections? If so- and it will mount up in the same configuration - I cannot see why is could not work.

I would look at the mounting flanges to see if those need to be modified.

Comparing the two parts diagrams and looking at the 7300 cooler the mounting bolts look the same and I can probably fabricate something to fit if they're not. The problem is that the hydraulic metal tubing seems to connect to the oil lines in a different manner. The 7400 looks to have mechanical pressure fittings. The 7300 has some tubing connectors that are rubber and hooked on with clamps. Thought maybe someone had some experience with this model.

B7100's use a small piece of hose and two clamps as mentioned....

I'm sure you could adapt that style to fit as long as the mounting hold firm
