So it turns out my 1550 was born with a gas engine, and one of the previous owners swapped in a 770 diesel. “Pretty close to the same” but it looks like it was done in a hurry.

Hoping you guys will give me some advice regarding the radiator. It looks like it will be easier to fabri-cobble the 770 rad into the 1550 mounting, or better to try making a 1550 rad fit the 770 engine?

At the very least, I’ll need to lower the rad about 7/8” because right now the fan hits the shroud.

I'd drill the radiator mounting holes lower..

I wonder if there is a water pump with the shaft higher up. Talk to Korves Oliver and ask Mark.

There are several water pumps for 770's and they do not all have the same center line for the shaft. Does the tractor have a Hydra-power?

Cut out 7/8 inch at almost to the bottom of the radiator bracket, and weld it back together.

I'd re-drill the radiator mounting holes in the sides of the brackets 7/8" lower.

Do some measuring for hood clearance. I put an 880 in a 1550. Ended up using a rad from a 1600 to get it sticking up out of the hood enough.

I think if you put a water pump for 1550 on it your problem will be fixed correctly. I think the pump for a 550 is the same, I measured mine and the shaft is about 1" higher than the one on my 77. The 77-1555 blocks are the same size.
