Parts Information:
NOTE: Use the Service Process Results Worksheet in the following page as a guide to determine
the appropriate Part Number(s).
1. Order the required parts based on the vehicle inspection results outlined in the Service Procedure
Flowchart. (Use the Service Process Results Worksheet in the following page as a guide to
determine the appropriate part numbers.)
2. Refer to TSB # 20-01-024H-2 (or latest revision) for parts information
3. Refer to HMA Warranty Policy prior to ordering a reman engine. A standard service engine or QQH
engine is required in certain cases.
Warranty Information:
NOTE: Use the Service Process Results Worksheet in the following page as a guide to determine
the appropriate Op Code.

choose one of the following methods:
 Select a Campaign T3G Op Code with the ECM update included if available, OR
 Submit a separate campaign claim for the ECM update using Campaign 953 op codes (in
addition to submitting applicable T3G op code)
2. Refer to TSB # 20-01-024H-2 (or latest revision) for OP Codes
3. Campaign T3G OP codes for engine replacement should only be used if engine replacement is
deemed necessary by the service procedure in this TSB.
 Refer to Prior Approval Submission Documentation at last page for checklist of PA items.
 General engine replacement for conditions outside of those contained in this TSB are not
covered by Campaign T3G.
Engine Oil Maintenance Information

Poor oil maintenance reduces the engine oil
lubrication and cooling capacities. As a result,
internal engine parts can be damaged resulting
in abnormal wear to internal engine parts,
excessive carbon deposits, sludge, and other
various conditions. An inspection for these
conditions and others may be required prior to
engine approval.

Piston Ring Deposits

NOTICE
Engine oil is used to lubricate, cool, and
operate various engine parts. Engine oil
changes and engine oil level checks are
required on a regular basis for all engines.

Oil Sludge

Engine oil level checks and top-ups are
recommended if they are needed prior to
the end of an oil change interval.

Excessive Wear

Service Procedure:
Initial Inspection:
1. Scan for DTC P1326 using the GDS.
 If DTC P1326 (or any other code) is present, take screenshot of Freeze Frame data for PA
using GDS screen capture if any DTCs are present and proceed to Step 2.
2. Check for any sludge under the engine oil filler cap.
 Using STUI on the GDS, take and submit a picture of the oil cap underside with the VIN in
the background of the photo (RO or last 6 digits written on paper). VIN must be legible.
 Sludge under oil cap: Submit Warranty Prior Approval (PA).
 No sludge under oil cap: Continue to next step.
3. Check for any engine oil on the engine oil dipstick.
 Using STUI on the GDS, take and submit a picture of the dipstick with the VIN in the
background of the photo (RO or last 6 digits written on paper). VIN must be legible.
 No engine oil on dipstick: Submit Warranty Prior Approval (PA)
 Engine oil on the dipstick: Continue to Engine Rotation Check.

Engine Rotation Check:
1. Rotate the crankshaft with the crank rotator SST.

and wheel liner or underbody tray as needed to
rotate the crankshaft.
 If the crankshaft rotates normally:
o Proceed to Bearing Inspection and follow the procedure sequence in Flow Chart A.
 If the force required for rotating the crankshaft is greater than 94 lb-ft., documentation
through STUI video is required.
o Follow the procedure sequence in Flow Chart B and note the following differences.
 If there is NO lower end damage:
o Follow the Oil Drain Procedure in the following page.
 If there is external lower end damage:
o Using STUI in the GDS, submit a picture of the damage with the VIN in the
background of the photo (RO or last 6 digits written on paper). VIN must be
legible.
o Follow the Oil Drain Procedure in the following page.

Practices guide for the latest requirements for engine approval.
1) If engine does not rotate normally, a STUI video including the following is required:
 VIN Plate (at windshield or on door jamb)
 Attempt to rotate the crankshaft
2) Save the crankshaft rotation torque value
3) A picture of the lower end damage is required if present
Additional documentation may be required:
 Refer to Prior Approval Submission Documentation at last page for PA required items.
 Use STUI feature on the GDS to take and submit pictures and videos.
Oil Drain Procedure:

Bearing Inspection:
1. Connect the main hose (shop air supply) and
test hose to the bearing tool (with other end of
the test hose disconnected). (The power to the
bearing tool main unit is not necessary at this
time.)
Confirm the shop air pressure and AP/VC
pressures on the bearing tool meet
requirements. The correct ranges for AP/VC air
pressures are also indicated with red/blue
decals on the gauges. Using STUI in the GDS,
take and submit a picture of the gauges with
the pressure levels clearly visible and the VIN
in the background of the photo (RO or last 6
digits written on paper) for records.
Shop air supply: 50 psi minimum
AP/VC air pressure calibration check:
a) Connect the main air compressor hose.
b) Connect the test hose. (The other end of the
test hose should be left disconnected from
the spark plug rod.)
c) Confirm that the AP/VC toggle switch at top
is in the middle position.
d) Inspect the AP/C gauge indicators and
compare to the specification range:
 AP: 0.1 ~ 0.11MPa
 VC: -73 ~ -83Kpa

NOTICE
Do not continue if any of the above readings are out of specification range.
 Adjust shop air to consistently provide at least 50 PSI of air pressure or greater.
 Do not use a portable air compressor to perform the bearing clearance testing.
 Be sure to check that the shop air water separator is functioning correctly.
 If any of the AP/VC air pressure indications are out of the specified range,
recalibration of the Bearing Clearance Tester is required.
o Refer to latest instructions outlined in the Engine Bearing Clearance Tester
Calibration Procedure TSB 20-GI-009H or later for calibration procedure.
