Camshaft sprocket bolt, single-bolt design

Torque-to-yield. This fastener is tightened past its elastic limit and permanently stretches. Always install a new one — a reused TTY bolt will not clamp to spec.

Tightening procedure

  1. Torque 55 lb-ft · 75 N·m
  2. Angle 50°

Complete the passes in the order shown. Angle passes are turn-of-the-nut steps measured with an angle gauge after the preceding torque pass.

Tools

  • socket
  • angle gauge
