Too! Instruction: 4328553 Digital Torque Tester Kit

Torque Wrench Set-Up

¢ Torque wrench data is required for all big bore engine repairs WPL2800136.

e Prior to torquing a connecting rod bolt validate torque wrench operation and calibration with
the Snap-On Digital Torque Wrench Tester.

e Average battery life is approximately 80 hours. If the batteries have been removed or replaced
exceeding 20 minutes the wrench will default back to the original factory settings.

e Which ever occurs first the Snap-On torque wrench will require a calibration check at 5,000
cycles or (1) year by a certified Snap-On repair center.

Tool Instruction: 4328552 CTECH3FR250A Digital Torque Wrench Set-Up

For proper torque wrench operation ensure the following:

1. Clear previous torque wrench data.

2. Check and set the correct date and time.

3. Check and set the correct present values.

4. (PSET 1) Target Torque: 22.0 ft/lb (30 Nm), Minimum Torque: 22.0 ft/lb (30 Nm), Maximum Torque: 23.0 ft/lb (31.1 Nm), batch (2).

5. (PSET 2) Target Torque: 77.0 ft/lb (105 Nm), Minimum Torque: 77.0 ft/lb (104.3 Nm), Maximum Torque: 78 ft/lb (105.7 Nm), batch (2).
6. (PSET 3) Target Angle: 90 degrees, Minimum Angle: 90 degrees, Maximum Angle: 91 degrees, batch (2).

Installation & Repair Step(s)

¢ Connecting rod bolts are torque to yield one time use.

¢ Engine damage will occur if one or multiple connecting rod cap(s) are mismatched or installed backwards.

¢ Do not use an impact to tighten connecting rod bolts.

¢ Do not use any universal adapters and swivels during torque procedure.

¢« Remove the oil pick up tube assembly for access.

« Complete connecting rod torque sequence prior to rotating the crankshaft.

If a connecting rod bolt is over torqued, both bolts have to be replaced and the cap has to be recentered. Premature failure will occur due to
uneven clamp load across the connecting rod cap if one bolt was replaced.

1. Review the appropiate engine service manual prior to disassembly and assembly.

2. Review general inspection procedure listed within the engine service manual prior to installation of engine components.

3. Clean all foreign material from the crankshaft journals and connecting rod assemblies.
4. Install one upper and lower connecting rod bearing, lubricate each with clean engine oil or Lubriplate #105.

5. A total of 2 new connecting rod bolts are required to complete connecting rod installation. Lubricate each bolt with clean engine oil first (3-4 threads) and flange, do not submerge
the whole bolt in oil, excessive engine oil can cause a connecting rod bolt to hydro-lock during installation.

6. Ensure fractured surface is clean. Install the connecting rod cap making sure the cap is centered and installed correctly aligning marks with upper portion of the connecting rod.

7. Install both bolts into the connecting rod by hand. Complete torque sequence in cylinder pairs (1/6), (2/5) and (3/4).

Do not alternate between connecting rods during this process. (PSET1) 22 ft-lbs (30 Nm), arrow up, (PSET2) 77 ft-lbs (105 Nm), arrow up, (PSET3) 90 degrees.
Note: Recommend starting with cylinder #1 complete all (6) steps prior to moving to another connecting rod.

8. Repeat Steps 4-7 for the remaining cylinders

9. Its required to review torque wrench data (36 steps) prior to installation of the oil pan assembly to ensure proper torque values.

10. Continue to downloading torque wrench data.

Viewing Torque Wrench Data

Torque wrench data can be viewed by downloading the .CSV file to a computer with an Excel based program or by viewing recorded data on the wrench.
