MAHLE Clevite has expanded the coverage for the 3406E Caterpillar engine which includes four new forged steel crowns and two skirts to accompany these crowns.

The patented MAHLE FERROTHERM piston design, which uses forged steel crowns and a separate aluminum skirt, is employed in these new pistons. This innovative design serves to increase the piston crown durability resulting in a longer engine life. Clevite pistons from MAHLE are the ONLY forged steel crown available in the Aftermarket for this application.

Clevite heavy duty engine parts have been packaged to specifically meet the needs of the engine rebuilder; they can be sourced in complete cylinder kits, separate piston crowns, pistons with skirt and pin or individual skirts.

Parts Included in Inframe Rebuild Kit
(6) Liner Kits (Sleeve/Liner, Piston, Rings, Wrist Pin, Liner Seals)
(6) Rod Bearings
(1) Main Bearing Set
(1) Upper Gasket Set
(1) Oil Pan Gasket

This Caterpillar Engine Kit is Clevite Heavy Duty Brand. All cylinder blocks must be precisely checked for concentricity and deck surface condition prior to liner installation. Anything less than perfect condition at these points can lead to cracked flanges on the cylinder liner. Failure to thoroughly inspect these two areas is the leading cause of liner flange cracking and should be the foremost consideration if liner flange failure occurs. Mahle Clevite warranty claims will not be considered without sufficent evidence on the cylinder blocks condition.

Please refer to Caterpillar repair procedure (SEHS9564-1) for inspecting your liner protrusion and cylinder block deck.

Head bolts marked with arrows are 216mm (8.5") long. The other bolts are 194mm (7.6") long. It is recommended to use a moly paste (Caterpillar # 6V4876) on all bolt threads. Without it you will not reach the proper torque value.

1. Torque bolts 1 through 26 (in sequence) to 200 ft/lbs (plus or minus 11 ftlbs)
2. Torque bolts 1 through 26 (in sequence) to 333 ft/lbs (plus or minus 15 ftlbs)
3. Torque bolts 1 through 26 (in sequence again) to 333 ft/lbs (plus or minus 15 ftlbs)

*Cylinder Head deck straightness should be within .13mm (.005") overall. The maximum warp spec is .03mm (.001") over any 76.2mm (3.00") span.
