Nanni 3100HE to Kubota?

I have two Nanni 3100HE engines and think one of my fresh water pumps is about to fail. I know these are marinized Kubota engines but have not been able to confidently identify which one was used for the 3100HE. I think it is the D1005-ES. Does anyone know for sure?

Might be a Johnson F5B9-10-24334-01 / ANCOR PUMP Model ST 143 - AN 2351

OOPS - that's a water pump">raw water pump.

Yes - thanks, the Johnson is the raw water pump but I am looking for the fresh water pump. Hence my need to nail done the Kubota model number. Any ideas for the fresh water pump?

Re: Nanni 3100HE to Kubota?

Look at the area of the injection pump for a models/SN stamped into the block. You might have to remove some paint

For similar models, there are two water pumps, one with 15 bolt holes, ther other with 16. My block takes the 15 hole pump.

Mine is in the attached picture, it's an '82 v-1902 kubota block marinized by Universal.

Attached is a cross-reference between block models and tractor models. You'll need the tractor model if you go to kubota dealer, they won't lookup parts based on block model.

I also attached a list of parts I used during my rebuild

Good luck

Re: Nanni 3100HE to Kubota?

Unfortunately my motor is not listed on the cross reference it seems though there several versions of the D1005. And fresh water pump has 7 holes so my engine is much smaller. Great info though. Thanks.

Re: Nanni 3100HE to Kubota?

See if you can find the exploded view parts diagrams. Usually that results in a "AHH! That's my engine." But, recognize that the manufacturers did not design new parts for the peripherals - water pumps, fuel pumps, starters, governors (for gensets) etc. usually are stock items they purchased off the internet, and so can you. The Universal M25 that powers my genset is a Kubota - starter for $1,164.95 from Westerbeke, $68.80 from various Kubota sources. Your engine may actually use one of several raw water pumps (mine uses two) by different manufacturers. My fuel solenoid is a stock item in supply houses for big diesel trucks. You're talking about a coolant pump (not a fresh water pump, that's a raw water pump) so it's probably standard as soon as you recognize your engine in the exploded views.
