HARDWARE TORQUE SETTINGS
The tables below give correct torque values for various
bolts and capscrews. Tighten all bolts to values in
charts unless otherwise noted. Check tightness of bolts
periodically, using torque charts as a guide. Replace
hardware with the same strength (Grade/Class) bolt.

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.
CHECK HARDWARE TORQUE

all hardware
Unless otherwise stated:
Hardware - Hex, GR5 UNC (imperial) or P8.8 (metric)
Hoses - 3/8, ends come with 3/4 JIC female swivel.
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!
