INSTALLING A GRS HYDRAULIC CYLINDER KIT
While the digger is attached to the tractor,
place under safe lifting device, such as a
chain hoist, or electric hoist if available.
Securely attach the chain to the hook eye and
use enough pressure to take the weight of the
mainframe off the turnbuckle and upper brace.
Bolt the hydraulic manifold block to the top of
the hitch as shown in the picture using 1/4” x
4” cap screws, lock washers, and hex nuts. Use
caution not to allow the hydraulic hoses to
drag in the dirt while assembling to help pre-
vent contamination from entering the tractor
hydraulic system. Attach the rod end of the
cylinders to the mainframe with 3/4” X 4-1/2”
bolts and locknuts. Attach the barrel end to
the hitch using 3/4” X 4” bolts and locknuts.
Refer to the parts book for attaching the proper hose to its appropriate location.
Swivel fittings do not need thread tape or other sealant. Stand away from the
drilling machine while removing the lifting device being used. The air in the hy-
draulic cylinders and hoses may allow for retraction or extension of cylinders
.
Fully cycle the GRS hydraulic cylinders 2 or 3 times to remove the air from the
lines.
REFER TO THE SECTION ON CHECKING THE LENGTH OF THE DRIVELINE ON THE
NEXT PAGE BEFORE CYCLING THE GRS HYDRAULIC CYLINDERS.
ATTACHING THE DRIVELINE TO THE
GEARBOX AND THE TRACTOR
Remove the tapered bolt in the end of the
torque limiter. Slide the clutch onto the
input shaft of the gearbox until the bolt
hole aligns with the groove in the shaft.
DO NOT FORCE THE SHAFT INTO THE YOKE. Turn
until a smooth fit is allowed. Insert the
tapered bolt and tighten with a wrench.
NOTE: To remove nut from tapered bolt, use
punch to drive head into yoke till taper
will keep bolt from turning with nut.
Next attach the Q.D. front yoke to the tractor PTO
shaft. DO NOT FORCE THE SHAFT INTO THE YOKE. Turn
until a smooth fit is allowed and then push the yoke
onto the tractor output shaft. Line up the pin in the
yoke with the groove in the shaft. After releasing the
Q.D. pin, pull on the yoke to insure a proper fit. If
yoke slides back, it is not properly attached. DO NOT
TAKE A CHANCE. BE SURE THE PTO IS PROPERLY ATTACHED.
LENGTH OF DRIVELINE
If it is necessary to shorten the
driveline, cut both sliding and guard
tubes equally. There should be ap-
proximately 1/2" of sliding tube ex-
posed.
