CAT C7 Injector Cup removal and installation. Step by Step. Part numbers included.

See how easy a injector cup job can be on a Diesel engine when you have the right tools. Watch from the best start to finish a C7 CAT injector cup job. This video was on a rebuilt cylinder head going on one of our Long Block assembly for stock. Normally you’ll find yourself doin this job with the engine in a truck application. Typically the customer complaint will be either fuel mixing in the coolant or coolant mixing in the fuel. The best way to verify which cup is leaking is too pressurize the cooling system with the injectors out. Definitely wanna go ahead and do all six. With the injectors out, you can also fill the cooling system back up and pressurize system to double check your work. I recommend replacing all injectors if coolant mixed with fuel and drain tanks. Definitely want to flush cooling system as well. Please like and subscribe. Thanks.

DT466 GM 6.6 L Duramax and Ford power stroke Plus the IDI 6.9 and 7.3

Can you use this tooling for the bigger cat engines? C10 c15?

[@hottboyjavon]

could oil coming out the top of the injectors slot be a case of bad injector cup or bad injector?? becausde i change the seals already and oil is still coming out

[@austinhmmm9087]

Out of curiosity, what did the problem end up being?

[@user-iw4cm5pt1g]

Where can I get a tool like that ?

[@spudlover96]

How did you buy the tool on the left? I’ve been to CAT for the past two weeks and they only sell the tool in the middle and tell me that’s all that’s available. My truck has been down for 3 weeks.

You should be able to order it from your local Caterpillar dealer with part number. Or tell a good Cat parts person you want a C7 injector cup tool group. Hope this helps.
