Application
Originally used on early Willys MB production, particularly slat grille version (November 1941 - March 1942). TR-marked bolts were characteristic of early chassis production and engine components. Later in the war, AA, EC and other markings were also used.
Installation notes
Cylinder head bolts must be tightened in correct sequence (see TM 9-803). Use thread sealant or loctite on threads to prevent corrosion and leakage. Recommended torque for bolts: 65-70 lb/ft. Re-torque after first 500-600 km. Older blocks may require helicoil repair for optimal thread quality.
Compatibility
This bolt fits L-134 'Go Devil' engines as used in Willys MB, Ford GPW and early M201. Specification: 7/16-14NC x 2¾ inch. Early engines used a mix of bolts and studs for cylinder head; later wartime production often had full stud configuration. Check original configuration for historical accuracy.
Historical context
The TR marking identifies the manufacturer of these bolts during WWII production. Early Willys MB slat grille jeeps (25,808 units produced between November 1941 and March 1942) primarily used TR20 and TR-marked bolts for body and engine components.
