I have a UTV with caterpillar/ Perkins 403c diesel engine loses power while driving and smokes, exhaust also has a hissing sound. Was wondering if it’s injectors or a more serious problem

Welcome to the Forums! Glad to have you.
How do you like the diesel powered UTV?
As soon as the right project comes along that I can "cough-cough" justify a UTV I want to buy one. Hard to justify one for a 1-2 acre site.

Thanks. I absolutely love it we got it new in 2006 it’s not built for speed like some of the newer UTV but is a workhorse i use it everyday on the farm . I sure do miss it since it’s been down

There’s a copper gasket that seals the bottom of the inj. to the head.. be sure to torque it down..usually 50-55ftlbs..
Squirt a little oil or some kind of liquid around the inj. while it’s running to check for compression leaks..

Did the spark arrestor screen fix the problem?

The diesel in a UTV is a torquey
SOB..
The only problem I’ve run across with them is, sitting for an extended period of time and the fuel going bad, sticking the plungers in the injection pump or freezing up the injectors..
THAT AND not changing the fuel filter a couple times a year.. allowing dirt/sand to enter the injection pump and wearing out the pumping plungers..

It’s running great now . I also noticed two of the injectors were loose when I took them off not sure if that was part of it

I had that same problem on a John Deere gator one time. It just wouldn't stay running. Start and die start and die. I checked fuel, air and all kinds of things. Had about decided that something was wrong inside the engine. Then one time after it died I heard a little hissing coming out of the exhaust system. That is when I found the spark arrestor screen was completely plugged!
