1 GENERAL REPAIR
Perform lockout/tagout procedures before adjusting, lubricating,
cleaning or otherwise servicing. Failure to do so could result in unexpected startup
and could cause serious injury or death.
To minimize risk of brake system failure and possible accident,
when servicing brakes or brake system:
• Do not over tighten brake tube fittings. Over tightening may crack the fitting or
damage the seat in the cylinder fitting.
• Compressed air used to service brake components must be oil-free or rubber
parts may be damaged.
• Always replace brake lines that are questionable.
• Never allow brake system rubber parts to come in contact with gasoline, diesel
fuel, or any type of cleaner other than an approved brake cleaner. Wash hands
before handling brake components.
• Brake linings that contact oil or grease can become contaminated, lose braking
friction and then must be discarded.
1.1 GUIDELINES FOR REPAIRING THE TRACTOR
The following are general instructions for the removal, disassembly, cleaning,
inspection, reassembly, and installation of tractor components within the capabilities
of the using organization. Common shop practices are not described. Use the
exploded views in parts manual, chapter 4 for reference.
1.1.1 Special Tools
There are no special tools required for this tractor. Common automotive shop tools
are all that is required to service the tractor.
1.1.2 Removal and Disassembly
Special instructions are noted in the appropriate text. Disassemble components only
to the extent necessary to do repairs.
1.1.3 Cleaning.
When cleaning, keep related parts together so reassembly is easier. Valves, pistons,
sleeves and other internal parts that have close tolerance fits in mating bores should
be cleaned individually to prevent surface scoring and marking. Special cleaning
instructions are given where required.
