Cummins ISX Single Cam Inframe Engine Rebuild Kit, New (ISX119161)

Restore Your Cummins ISX Single Cam with the ISX119161 Inframe Rebuild Kit

Is your Cummins ISX Single Cam burning oil, knocking, or losing compression? The ISX119161 inframe rebuild kit from 4BTdiesel gives you the cylinder liners, pistons, bearings, and gaskets needed to renew the engine’s wear components without pulling it from the chassis, saving the time and cost of swapping in a full replacement engine. Every ISX Single Cam eventually reaches the point where a rebuild is the right call, and the parts going back in determine how many miles you get before the next one. Some OE rebuild kits get filled out with reconditioned or take off pieces to keep the price down, which is the last thing you want sitting inside a freshly rebuilt engine. 4BTdiesel’s ISX119161 kit is built entirely from new components, manufactured to OEM specifications and tolerances in an ISO 9001 certified facility, so your rebuild starts with parts you can trust rather than parts that have already done their job once.

What’s Included in the ISX119161 Inframe Rebuild Kit

This inframe kit covers the major cylinder, piston, bearing, and gasket components needed for a thorough ISX Single Cam rebuild.

Cylinder Liner Kits and Piston Kits

Six cylinder liner kits, part numbers 4376391 and 4373362, replace the liners for every cylinder in the bank. Six piston kits, part number 2882023, bring fresh pistons to match, restoring proper compression and oil control across all six cylinders.

Main Bearing Set, Rod Bearings, and Upper Engine Gasket Set

The kit rounds out the bottom end with a main bearing set, connecting rod bearings, an oil pan gasket, a bypass valve plunger, a thermostat, and an O-ring seal. A complete upper engine gasket set, part number 4376104, handles the seals on top of the engine, so the rebuild covers both the lower and upper portions of the assembly.

Because rod and main bearings come machined to specific clearances, you will select a rod bearing size and a main bearing size, Standard, .010, .020, .025, .030, or .050, at checkout to match your crankshaft’s current dimensions. Diesel inframe kits are engine specific, so 4BTdiesel also asks for your engine serial number, VIN, or CPL prefix so the parts team can confirm fit before the kit ships. If your engine carries CPL prefix 3719 instead of 3606 or 3939, you will want 4BTdiesel’s other ISX Single Cam kit, 5579461, built for that specific prefix, rather than this one.
