I just finished swapping a V2203 out of a reefer into a New Holland LX665. I'm working on getting the governor to respond as a variable speed, not a constant. Do I need to change the springs? Currently, it has one large spring. I have looked up a tractor and a skid loader that have a 2203 in and it looks like there are 3 springs. If anyone has come across the same issue, please let me know what helps.

The governor is the problem - the reefer engine ran at one speed and one speed only.

Problem is I think you have to change more than springs (but I am no expert).

@North Idaho Wolfman or @whitetiger should be along to give you proper guidance.

No reefer engines are a variable RPM engine and governor, they just use a actuator to go to full RPM on cooling activation.

Generator engines are the only ones that I know of that are a fixed RPM governor.

Will need to know if it's an IDI or DI engine as the governor and throttle springs are set up differently on each.
