Using JDG738 Connecting Rod Bushing Service Set,
proceed as follows.
1. Slide driver JDG738-1 (A) into one side of rod
bushing (C). Turn driver until taper on driver flange
matches up with taper on bushing.
2. Install receiver cup JDG738-3 onto opposite side of
rod bushing.
NOTE: Stud in cup keeps rod properly located on the
cup. Use JDG738-2 pilot ring (B) as a hollow
spacer when pressing bushing out of rod.
3. Using hydraulic press, push bushing out of rod until
driver and bushing fall into receiver cup

4. Slide bushing (A) onto JDG738-1 driver (B) and
install JDG738-2 pilot ring (C) onto O-ring end of
driver.
5. Apply TY6333 grease* to:

 Outside diameter of bushing

Outside diameter of pilot ring

Inside diameter of rod pin bore

6. Insert driver into rod pin bore so pilot ring pilots in rod
bore and bushing taper aligns with taper on driver
flange. Align oil hole in bushing (D) with oil hole in end
of rod (E).
7. Install JDG738-3 receiver cup (F) onto opposite side
of rod so taper on rod aligns with taper on receiver cup.
8. Press bushing into rod until edge of bushing is flush
machined surface on connecting rod face.
IMPORTANT: Oil holes MUST be aligned. If holes are
not aligned, remove and discard
bushing then re-install a NEW bushing.
DO NOT attempt to reuse a bushing.
9. Have the new bushing reamed by a specialized
workshop to obtain an oil clearance of 0.020 to 0.056
mm (0.0008 to 0.002 in.) with piston pin.

4 Remove drain plug C and let the coolant drain out.
   Make sure the drain hole is not blocked.
5 Disconnect the radiator hose at D and allow the coolant
   to drain. Flush the system using clean water.
6 Clean and refit plug C. Make sure it is secure.
   Reconnect the radiator hose
7 Use the necessary mix of clean, soft water and
   antifreeze, see Coolant Mixtures. Fill to the COLD/MIN
   level on coolant reservoir B.
8 Start the engine and run at idle to circulate the coolant,
   top up with coolant as necessary.
9 Refit the filler cap. Make sure it is tight.
10 Run the engine for a while, to raise the coolant to
   working temperature and pressure. Stop the engine.
   Check for leaks.
   Note: Make sure the cab heater control is in the hot
   position. This will ensure the coolant mixture circulates

Cummins CFP11E series Fire Pump Drive Engine change the fuel filters Replace Steps

 This Article Mainly Introduces Cummins CFP11E series  Fire Pump Drive Engine change the fuel filters Replace Steps       

     Cummins INSITE 8.7 Pro 2021 Electronic Service Diagnostic Software

As shown in Figure 5-4, inspect the fuel injection pump mounting nuts (including the support bracket) for loose
or damaged hardware. Inspect the fuel line hoses and fuel filters for wear, damage, loose fittings, and leaks.
Repair or replace damaged hoses and filters as required.

Cummins INLINE 6 Data Link Adapter Truck Diagnostic Tool

Engine fuel is highly flammable and represents an extreme hazard for fire or explosion when exposed
to electrical sparks or open flame. Clean up spilled fuel immediately. Keep sources of electrical spark
or open flame away from a fuel source.
Do not open the fuel filter/water separator drain valve or dismantle the fuel lines on the high-pressure
fuel system with the engine running. High pressure fuel spray from an operating engine can cause
serious personal injury or fire hazard.
To change the fuel filters:
1. Shut off the engine.
2. Close any fuel valves (if equipped) to prevent fuel from draining or siphoning.
3. Clean the area around the fuel filter or fuel/water separator heads.
    NOTE: Refer to the engine data sheet for filter replacement recommendations.
4. Remove the spent filter canisters using a filter wrench.
5. Clean the filter mounting head surfaces of sludge buildup and foreign particles.         Ensure mating gasket surfaces are clean.
6. Lubricate the gasket seals with clean SAE 15W-40 lubricating oil.
7. Center the filter ring on the threaded mounting nipple. Screw the filter canister  onto   the mounting flange
    until the gasket is snug against the mounting flange, then tighten an additional 1/4 turn.
8. Open the fuel supply valves (if equipped).
    Mechanical over-tightening can distort the threads or damage the filter element seal.

9. Press either the CRANK BATT A or CRANK BATT B button to start the engine to allow the fuel to flow
    through the system.
10. Depress the contactor switch for up to fifteen seconds or until the engine starts. Repeat up to three times,
   if necessary
