BOLT TORQUE

Mounting procedures for mowers will require a significant amount of bolt nut and washer installation.

Frame and structure mounting bolts should be installed using Red Loctite, and torqued to the dry values listed in the torque chart based on the bolt size and hardness.

Other structures such as pump mounting bolts should be installed with Blue Loctite and torqued to the dry values indicated in the chart.

Bolt tightness should be completed with and checked with a suitable torque wrench.

Torque checks should be completed throughout the life of the mower in accordance with the maintenance chart provided in this manual.

Loose bolts on a frame or in a casting may be a result of:

●● Vibration from the mower due to imbalance of the mower blades ●● Pulled threads due to over tightening

●● Distortion of the hole due to under tightening during installation

Bolts broken or sheared in the mounting structure or tractor may be the result of:

●● Improper alignment of the Mounting Plate or Structure such that it is not sitting flat on the mating surface

●● Distortion of the bolt due to over-tightening ●● Under tightening of the bolts

Check the bolt torque during installation and prior to delivery with a suitable torque wrench.
