8.2 ADJUSTMENTS
8.2.1 Adjust Apron Chain Tension (Daily Every 8-10 Hours)
Visually inspect the tension on the apron chains.
Initial break-in of the chain will require visual inspection
every hour for the first 100 hours of service.
The second apron chain slat (approximately three feet
back from the front of the box) should be 1/8” to 1/4” off
the return slides (both sides).
Alternatively, torque each tightener bolt to 30 ft/lbs.
Tighten the adjuster bolts (Item 1) at each end of the
front sprocket shaft equally.
NOTE: If adjuster bolt(s) reaches maximum travel,
remove equal links from each strand.
Removable links are provided in the chain.

Chock all four wheels or hitch to tractor with engine
off, key removed and parking brake set. Jack empty
trailer off ground and support with adequate jack
stands.

3.
If adjusting bearings, it is suggested the bearings be repacked as described previously.
