For standard capscrews: 1. Always use the torque values listed the capscrew table. 2. Reduce torque by 10% when engine oil is used as a lubricant. 3. Reduce torque by 20% if new plated capscrews are used. – 248 – Y53-6008A Medium Duty (R05/09)
Preventive Maintenance Introduction FRAME AND FIFTH WHEEL WARNING! Do not cut or splice frame rails or drill through the top or bottom flanges. These operations could affect frame rail strength leading to a failure resulting in serious personal injury and/or an accident. Always leave frame repairs to your Peterbilt Dealer. Engine Painting • Do not electrostatically paint electronically controlled engines or vehicles with these engines. Welding • Observe these recommended procedures to protect electronic systems during welding operations. Engines Before welding on vehicles equipped with electronic engines, the following precautions should be observed: Frame and Fifth Wheel NOTE: Welding to frame rail may void frame rail warranty. • Disconnect all electronic connections to the vehicle batteries. • Remove battery power cable and insulate it from the vehicle. • Disconnect all Electronic Control Module (ECM) connectors (on electronic engines). • Do not use the ECM or engine ground stud for the ground of the welding probe. • Ensure that the ground connection for the welder is as close to the weld point as possible. This ensures maximum weld current and minimum risk to damage of electrical components on the vehicle. • Turn engine OFF. All Anti–Lock Braking Systems (ABS) • Before welding anywhere on the vehicle, detach the ABS Electronic Control Unit (ECU) connector and all other electronic control units.
