Checking The Gearbox Lubrication - Toro ProCore 864 Operator's Manual

Important:
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 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. Use of sealed bearings minimizes
routine service and reduces the potential turf damage
from grease contamination. Inspect of bearing
condition and seal integrity periodically to avoid
downtime. Inspect the sealed bearings seasonally
and replaced them if they are damaged or worn.
Check that the bearings do not produce high heat,
emit noise, vibrate excessively, or weep rust; the
bearings should operate smoothly.
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 other than defects in
materials or workmanship are typically not covered
under warranty.
Note:
Bearing life can be negatively affected by
improper washing procedures. Do not wash the unit
when it is still hot and avoid directing high-pressure or
high-volume spray at the bearings.
New bearings commonly purge some grease out of
the seals on a new machine. This purged grease turns
black in color due to collection of debris and not due
to excessive heat. Wipe this excess grease from the
seals after the initial 8 hours. The area around the seal
lip may always appear wet. This is not detrimental to
bearing life, but keeps the seal lip lubricated.
Replace the coring head bearing every of 500 hours.
A bearing service kit that covers the complete coring
head is available from your distributor.
Checking the Gearbox
Lubrication
Service Interval: Every 100 hours
The gearbox is filled with 80W-90 gear oil or
equivalent. Allow the gearbox to cool before checking
the lubrication.
1. Clean debris from the fill plug and check the plug
to avoid contamination.
2. Remove the check plug from the gearbox
(Figure 30).
1. Fill plug
2. Check plug (rear of
gearbox)
3. Make sure that the oil level is up to the bottom of
the check plug hole in gearbox
4. If the oil level is low, remove the fill plug from the
gearbox and add oil as required.
5. Install the plugs.
