Maintenance - New Holland 499 Operator's Manual

Complete all checks and services in this section at
the hour interval shown. Use the hour meter in the
tractor as a guide for determining when maintenance
is required.
IMPORTANT: Failure to complete the required
maintenance at the interval shown can cause
unnecessary downtime.
The recommended maintenance intervals are for
average conditions. Perform maintenance more
often when operating the unit under adverse
conditions.
The maintenance items in this section are listed by
hour intervals. All items within a particular hour
interval are listed in a logical sequence.
Careful inspection and service of the unit prior to
operation each day will prevent needless break-
downs and delays in the field. Make the following
checks and adjustments.
1. Check all belt drives and chains carefully for
proper alignment and tension. Belts can be
ruined very quickly if allowed to slip in the
grooves of a sheave for any length of time.
Excessive heating of a sheave is an indication of
belt slippage. New belts will stretch during the
first several hours. Check tension frequently.
