SAFETY NOTICE	SN687

 

DATE: 11/16/2020
REVISED:

 

TO: Owners, Users, Dealers, and Installers

MODELS AFFECTED: TL80 & TL100

 

SUBJECT: Rotation Bearing Bolts

 

Issue:

Terex Transmission TL models TL80 & TL100 aerial devices, produced from April 2019 through August 2020, may have rotation bearing bolts that will loosen.  The loosening of the bearing bolts may cause the bearing bolts to fail.  Failure of the rotation bearing bolts could cause the boom to fall which could result in injury or death.

 

Action:

What the Owner Must Do:

The owner must inspect their equipment and correct if required:

1. Immediately inform all users, operators, and supervisors that the rotation bearing bolts must be inspected daily before use.
2. Inspect to determine if it has loose rotation bearing bolts using the following figures as reference. All rotation bearing bolts must be inspected; both the rotation bearing bolts connecting the rotation bearing to the pedestal and the rotation bearing bolts connecting the rotation bearing to the turntable need to be inspected.  The rotation bearing bolt inspection only applies to units without a hydraulic lift.
   1. The inspection involves a torque check on all rotation bearing bolts using a calibrated torque wrench. The torque required for the rotation bearing bolts on the TL80 & TL100 is 350 ft-lbs.
   2. Any loose bearing bolts are to be retorqued to 350 ft-lbs using a calibrated torque wrench. For this issue, any loose bolts can be retorqued without replacement.  Any missing bearing bolts and/or washers are to be replaced with new hardware using the parts section of the manual to determine the correct bolt and/or washer part numbers.

1. After the rotation bearing bolts are retorqued, apply torque striping across the bolt head and washer to the bolting plate to aid in daily visual inspections.
2. After retorqueing all rotation bearing bolts, the unit can be used following the instructions in the continued use section below as well as all operator, maintenance, and inspection requirements as specified in the manuals.

 

Continued Use:

Inform the users of the content of this bulletin and remind them of the daily pre-shift inspection requirements.

1. Inspect the rotation bearing bolt torque stripe daily before use until Field Service Kit Z1604 is installed, using the above picture as reference.
   1. If the torque stripe is intact and/or the washers do not move on all rotation bearing bolts machine use can continue until Field Service Kit Z1604 is installed, following all operator, maintenance, and inspection requirements as specified in the manuals and this bulletin.
   2. If the torque stripe is broken or the washer is loose on any of the rotation bearing bolts, retorque the bolt to 350 ft-lbs with a calibrated torque wrench. After retorqueing any required bolts, machine use can continue following the daily visual inspection and retorquing as needed until Field Service Kit Z1604 is installed.
2. Every 30 days after the initial torque check (Step 2 of the Action), perform a torque check on all rotation bearing bolts following the same procedure as in Step 2 of the Action.
3. Continue with the daily visual inspection of the rotation bearing bolts and 30-day torque checks until Field Service Kit Z1604 is installed.
