Note: If desired, an additional grease fitting may be
installed in other end of steering cylinder. Tire must be
removed, fitting installed, greased, fitting removed and
plug installed (Fig. 49).
Sealed Bearings
Bearings rarely fail from defects in materials or
workmanship. The most common reason for failure is
moisture and contamination working its way past the
protective seals. Bearings that are greased will rely upon
regular maintenance to purge harmful debris from the
bearing area. Sealed bearings rely on an initial fill of
special grease and a robust integral seal to keep
contaminants and moisture out of the rolling elements.
The sealed bearings require no lubrication or short term
maintenance. This minimizes routine service required and
reduces the potential of turf damage due to grease
contamination. These sealed bearing packages will provide
good performance and life under normal use, but periodic
inspections of bearing condition and seal integrity should
be conducted to avoid downtime. These bearings should be
inspected seasonally and replaced if damaged or worn.
Bearings should operate smoothly with no detrimental
characteristics such as high heat, noise, looseness or
indications of corrosion (rust).
Due to the operating conditions these bearing/seal packages
are subject to (i.e. sand, turf chemicals, water, impacts, etc.)
they are considered normal wear items. Bearings that fail
due to causes other than defects in materials or
workmanship are typically not covered under warranty.
Note: Bearing life can be negatively affected by improper
wash down procedures. Do not wash down the unit when it
is still hot and avoid directing high–pressure or high
volume spray at the bearings.
