B7100 HST. D950 engine swap

[BrianD]

Has anyone done an engine conversion from a D750 to a D950 on their B7100? I was wondering how you routed your coolant hose from the water pump down to the lower radiator opening. Does any have any pictures they could share? It would be greatly appreciated.

There is a fitting for that, but it's hard to find.
You can use a piece of thin wall pipe up against the gear case behind the belt.
You will also need to neck down both inlet and outlet of the radiator.
I use 1" copper adapters to do it, and sweat them in.

Thank you for the info I will give that a try. What coolant hoses from model of engine work the best in this application.

Oh here is that water pipe, and hoses I made my own from off the shelf pieces.
But you could use the hoses from a B7200:

Water pipe: https://www.messicks.com/part/15531-72860/PIPE-WATER-2
Or: https://www.colemanequip.com/parts/details/KubotaParts/PIPE--WATER-2/15531-72860/
Or: https://kubotageneratorsdirect.com/product/15531-72860/

Water pump to water pipe: 15531-72870
Water pipe to radiator: 15759-72850
Thermostat to radiator: 15752-72940
