Hello Mark,

Has your UTV Dr resolved your problem yet?  If you can't get good factory injectors, then where can you get them.  I haven't started on mine yet, as we are finishing up a cattle watering project.  Also I need to get a new spark plug wire, which arrived yesterday.  One problem I have is that I have no UTV repairman within about 60 miles, so I and a hand am going to have to troubleshoot and solve the probleem.  Keep me posted - I have a feeling my problem is also going to be the injector.

I you'd like to try the injector, the part # is 28160355.  On ebay they are about $10-$20.  Easy swap out.  But, with 300 on it, I'd bet on the timing chain.  Easy check; two small bolts to pull out the tensioner.....

Hi Rich shop decided that it's the injector so they ordered a new one from coleman not sure it'll be any better  but if they put it in its their problem when it fails machanic said said there's always junk in the fuel tank from  the factory and it plugs up the injector I hate taking it to a shop I could change it myself but I worry about voiding the warranty and what if somthing serious would happen  but anyway that's all I have for now good luck 

An injector is about $12, and yes, that is a possibility. As this UTV had only 200 hrs, that's what I did first, and quickly found how wrong that knee-jerk solution was.  If that new injector does not help, you might suggest that they pull out the chain tensioner to see if there is any tension on the chain.  If not, that's the problem....  If so, hope there's a warranty in effect, as the engine has to come out for replacement.

I have a 2022 Coleman UT 550X Outfitter purchased April 2022 that has about 200 hrs on it.  About 4 weeks ago we noticed a little difficulty in starting.  Instead of the usual starting without giving any pedal, we had to depress the accelerator pedal slightly in order for it to start and keep on running.  Otherwise it ran fine, but last week, it would not start at all.  We have checked the fuel pump, fuel filter and spark, and all seem fine.  We actually replaced the spark plug.  Don't know where to go from here - anybody have any suggestions?

Thinking of the one here that I just took apart w/200 hrs on it, I expect the timing chain is shot.  As the chain wears, it retards cam timing, and starts to slap -tighten/loosen-as the engine spins, so the valves open/close at the wrong times. Finally, cam timing is so far off that there's little or no compression, and/or the chain jumps a tooth or two.....so the engine fires someplace other that just before TDC..   Fairly easy to get to the timing chain tensioner, pull it out to see if it is at full extension (no tension on chain).  If so, the chain is toast.....

107 hours. 

Make sure you change the oil chain while you are in there.

It was a horrible process. Lots of home made tools because I did it with the engine still in the cart. 

Unreal that the chains are such garbage to crap out at 100 hours. The cart still looks brand new.

Be careful re-fitting the case cover that its flush before you start tightening the bolts. There are so many possible catch points (water pump) that you might think its on and start tightening and then CRACK as you crack the case. As me how I know!

Thanks for responding.  The one here shows 200 hrs.  The chain is sloppy loose with the tensioner at full extension.  I've told the owner that it makes no sense to do all the work necessary to replace both chains, as there's no reason to think the new chains will be an improvement over the current ones....  The chain appears to be too small for the application, as it is much smaller than motorcycle timing chains, but about the size of 50cc scooter chains.  In any case, I won't consider trying to do that work with the engine still in place......

 

 

I know this is a old thread; but how many hours were on this UTV?  I have one here with only 200 hours, and

the timing chain is shot!  Thanks....
