HARDWARE/HOSE SPECIFICATIONS
Unless otherwise stated:
• Hardware - Hex, Plated GR5 UNC
(imperial) or P8.8 (metric)
• Hoses - 3/8, ends come with 3/4
JIC female swivel.
Important:
Check torque on all hardware
periodically. Check after first 2,
10, 40, then every 200 hours.
• Torque values listed are for
general use only. If a different
torque value or tightening
procedure is specified for a
specific application, do not use these values.
• Refer to the “Parts” section for proper grade and
length of bolts for replacement parts.
• Do not replace locknuts with nuts and lock washers.
Replace all parts with original, specified parts only.
• Dry values shown mean the bolt/nut is plain or zinc
plated without any lubrication.

HYDRAULIC SAFETY
1. Always place all tractor hydraulic controls in
neutral before dismounting.
2. Make sure that all components in the hydraulic
system are kept in good condition and are clean.
3. Replace any worn, cut, abraded, flattened or
crimped hoses and metal lines.
4. Do not attempt any makeshift repairs to the
hydraulic lines, fittings or hoses by using
tape, clamps or cement. The hydraulic system
operates under extremely high pressure.
Such repairs will fail suddenly and create a
hazardous and unsafe condition.
5. Wear proper hand and eye protection when
searching for a high pressure hydraulic
leak. Use a piece of wood or cardboard as
a backstop instead of hands to isolate and
identify a leak.
6. If injured by a concentrated high-pressure
stream of hydraulic fluid, seek medical attention
immediately. Serious infection or toxic reaction
can develop from hydraulic fluid piercing the
skin surface.
7. Before applying pressure to the system, make
sure all components are tight and that lines,
hoses and couplings are not damaged.
Think SAFETY! Work SAFELY!
