Cummins ISX15/QSX15 SOHC Injector Sleeve “Replacement Tips”

OurCummins ISX15/QSX15 SOHC Injector Sleeve Kitallows a machinist to remove & install injector sleeves.

Changing these injector sleeves is very basic, however, a common question we receive frequently is: “What do we do with the “Ring” at the top of the inside diameter of the old sleeve”.

This “Ring” is actually a warranty field fix for a premature leaky injector sleeve, which leaked fuel or coolant at the top of the injector sleeve. It is a one-time warranty field fix used by the OEM or Fleet Operator. These upper Retaining Rings are not to be used again after fresh injector sleeves are installed.

To remove these upper retaining rings, using a drift or punch, coming into the injector sleeve from the deck surface, take the drift or punch and knock out the ring towards the spring side and remove the ring from the injector sleeve once it’s loose.

现在我们可以把注射器套筒install it per our normal instructions.

With proper Injector Sleeve installation, the cylinder head is brought back into service at OEM specs, the cylinder head is then: “Irontite”.

These are the “Best Diesel Tools” on the market and a Great Opportunity for everyone to make some additional $$$ along with keeping our industry alive!!
