In Order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 40% of dealership population. This is an inital order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.

ACTION REQUIRED

Show/hide table

1) Place the machine on stable, level ground and raise the front wheels off the ground. Secure the machine in this position.

2) M315C, M316C, M318C, and M318D: check the serial number on the axle. The axle serial number is located on the identification plate on the rear of the left axle housing. If the axle serial number is below SN 808237, then this service letter MUST be performed, otherwise your machine has an improved axle housing with M18 bolts and the service letter is not necessary.

3) Remove the wheel(s) from one side of the axle to expose the trunnion bolts that need to be replaced.

4) One by one, remove each of the (8) 8T-4779 bolts and replace it with a 314-5416 Bolt Special. Tighten the 314-5416 bolts to a torque of 207 lb ft (280 Nm).

***NOTE: on M315C, M316C, M318C, and M318D: if the bolt removed is M18 and not M16, then this service letter MUST NOT be performed***.

5) When all 8 bolts have been replaced, check to ensure that all bolts have been tightened to a torque of 207 lb ft (280 Nm), remount the wheel, and perform the same procedure on the other side of the axle.

***Service Note: if a 314-5416 Bolt Special should need to be removed in the future, then it must be replaced and never reused.***
