SUBJECT: WEARING OF THE HOSES FOR THE HYDRAULIC OIL FILTER

PROBLEM:

The hoses for the hydraulic oil filter are subject to wear during machine operation due to contact with frame bolts, hoses, clamps, sharp edges of the frame, etc. This situation can ultimately result in failure of the hoses.

SOLUTION:

Inspect the hoses for the hydraulic oil filter for wear and replace the hoses as necessary. Reposition the hoses to minimize contact with frame bolts, hoses, clamps, sharp edges of the frame, etc.

Note: Lengths of the 160-2243 Abrasion Sleeve can be installed on the hoses for added protection.
