Engineered specifically for 2011 through 2022 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.7L Powerstroke V8 turbo diesel engine, the MAHLE Original (Clevite) Crankshaft Thrust Washer Set (Part # TW-711S) provides essential control over crankshaft axial end play. During engine operation, clutch engagement, torque converter loads, and thermal expansion push and pull the crankshaft forward and backward along its centerline. Without proper thrust surface support, excessive axial play allows the crankshaft to "walk," wearing down main bearing journal faces and destroying the engine block and rotating assembly.

As an original equipment supplier to major diesel manufacturers, MAHLE builds the TW-711S set to meet strict factory metallurgical standards. Constructed with durable wear-resistant bearing material on a steel backing, these thrust washers maintain proper oil film retention and uniform load distribution against the crankshaft thrust journal. Sold as a matched set for standard journal sizes with zero core charge, replacing these washers during a bottom-end rebuild guarantees correct crankshaft positioning.

Key Features & Benefits

• OE-Quality Manufacturer Standard: Engineered by MAHLE to match or exceed original equipment dimensional and material specifications.
• Controls Crankshaft End Play: Restricts excessive axial shaft movement ("crank walk") caused by transmission loads and torque converter pressure.
• Durable Bimetal Construction: Features wear-resistant bearing alloy bonded to a high-strength steel backing for long-term durability under heavy diesel service.
• Precise Journal Alignment: Promotes wide, uniform contact against the crankshaft thrust face to prevent localized scoring and friction.
• Zero Core Charge: Brand-new outright engine component requiring no core deposit or core return shipping.

• Important Sizing Note: Designed for standard, un-machined crankshaft thrust faces. If the crankshaft has been ground on the thrust surface, oversized washers must be utilized.
• Installation Tip: Install thrust washers into their designated main bearing cap or block saddle with the oil-groove side facing outward toward the crankshaft thrust face. Measure final crankshaft end play with a dial indicator during assembly to verify it falls within factory Ford specifications before closing up the crankcase.
