Specialty #09-12

Idler Spring Can Be Over-Extended

Product: ProCore Processor November 4, 2009

Affected Units:

ProCore Processor

Models:

09749

Serial Numbers:

280000101-290099999

Situation:

The Arm-Idler, ASM (110-2717) has a feature to allow the use of ½” drive socket wrench or breaker

bar to aid installation and adjustment of the primary drive belt. The geometry of this adjustment in

the listed units can allow the Spring- Extension (54-2730) to be pulled past its design yield point.

This can cause damage to the spring that will result in insufficient tension applied to the idler

assembly and eventual belt failure.

Instructions:

Refer to the attached revised Operators Manual pages for instruction to avoid spring damage.

Please contact your local Toro Commercial Products Distributor for additional information on this

issue; reference Commercial Service Bulletin Specialty 09-12 when making your inquiry.
