Known issues on the 1986 L1317. The 1986 L1317 has a single recall, and it deals with load rating rather than a failing part. Certain heavy-duty trucks equipped with type 14 brake chambers on the rear axle fell short of federal air brake standard 121 at their original rear axle rating of 21,200 lbs, so the rating was reduced to 20,000 lbs as the axle's maximum carrying capacity. Rear axle specifications, brake chamber procedures and torque values are covered in the manual.
