Idler Chain Adjustment - Manual Adjust (Frontier)
A loose or improperly adjusted idler chain can result in damage to the chain or
sprockets. During the new vehicle break-in period, check the idler chain adjustment
before operating the vehicle and after the first 2 hours of operation. After the initial
break-in period, check the idler chain adjustment every 50 hours. An indication of loose
idler chains is a loud banging noise when the vehicle is turned.
To check the idler chain adjustment, push
the slack side of the chain and measure
the amount of chain deflection. Adjust the
idler chain tension if deflection is more
than 3mm (1/8").
1. Remove the firewall from the vehicle.
2. Loosen the 2 left side clamping nuts
with a 15/16" socket wrench.
3. Turn the vertical adjustment bolts
counter-clockwise to raise the power
pack and tighten the idler chains. The
idler chains are properly adjusted when
the deflection measures 3 mm (1/8").
4. Tighten the 2 left side clamping nuts
securely.
