How to test the injections in the tractor

Injectors??? Suppose you take a minute and tell us what you are trying to do and why. Brand and model of tractor would help as well. welcome to TBN.

If your trying to narrow down a skip/miss..
Start the machine and get it skipping.. Loosen the nut AT THE INJECTOR.. it’s will start to leak as the pump rotated so it’s handy to have a rag..
Loosen and tighten the lines as u go down the line..
Your looking for the cyl that doesn’t make the engine lope..

Once u find the cyl/injector that’s suspect, u can move it to another cyl or hook it up OUTSIDE the engine..to watch the spray pattern..
BE VERY CAREFUL WHEN YOU DO THIS.!!! The SPRAY FROM THE TIP CAN AND WILL PENETRATE YOUR SKIN AND GIVE U BLOOD POISONING.!!!
No need to worry about it just loosening the lines..
UNLESS your working on a tier 4-5 engine..
