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

• Whichever occurs first (1) year, 5,000 cycles or CAL NEEDED message the torque wrench will
require a calibration check by an authorized Snap­On repair facility refer to TL2900164

• 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

Installation & Repair Step(s)
Review the following IK articles:

Connecting rod bolts are torque to yield one time use discard after removal
Engine damage will occur if one or multiple connecting rod cap(s) are installed backwards
Do not use an impact to tighten the connecting rod bolts
Do not use any universal adapters and swivels during torque procedure
Remove the oil pick up tube assembly for access

1. Review the N13 Engine Service Manual prior to disassembly and assembly.
2. Review General Inspection Procedure listed within the N13 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 (12) 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. Install the connecting rod cap making sure the cap is centered and installed correctly aligning marks with upper portion of the connecting rod.

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

7. Complete installation and torque sequence by hand threading both bolts into the connecting rod alternating back and forth while seating the cap. Start with
cylinder #1 and complete in pairs (1/6), (2/5) and (3/4). Torque connecting rod bolts in three steps starting with preset: (PSET1) 22 ft-lbs (30 Nm), arrow up,
(PSET2) 77 ft-lbs (105 Nm), arrow up, (PSET3) 90 degrees.
8.Continue to downloading torque wrench data.

• 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.
