SLIP CLUTCH DRIVELINE INSTALLATION (cont.)

10. Check the swinging drawbar of the tractor and make

sure the PTO driveline assembly will not contact. The
swinging drawbar can be moved forward on some
tractors or it can be removed.

If the PTO driveline assembly contacts the swinging

drawbar, damage will occur to the driveshaft shield and
possibly the driveshaft itself. (NOT covered under
warranty.)

When attaching PTO yoke to tractor PTO shaft, it is

important that spring-activated locking pin or balls
operate freely and are seated in groove on PTO shaft.
A loose shaft could slip off and result in personal
injury or damage to equipment.

Route the hoses to your tractor remote hydraulic

couplers. Be sure to allow a loop of hose just behind the
attachment to allow for the angles that will be
encountered. Make sure that the hoses are routed so
they will not be pinched or snagged by implement or 

tractor parts. Fasten the hoses securely so they will
remain in the correct position and not drop down where
they could be pinched or sheared.

After making the hose connection between the tractor

remote outlets and the hydraulic cylinders, operate the
cylinders several times to work the air out of the system.

Check hydraulic fluid level in your tractor after filling the

cylinders and hoses.

NOTE:

If your tractor has a 

closed center

hydraulic

system, turn the flow control on the remote hydraulic
outlet block to minimum flow.

If your tractor does not have a flow control, contact

Worksaver, Inc. for a restrictor orifice fitting to reduce the
flow. This will minimize the heat build up in the tractor
closed center hydraulic system.

Order optional throttle valve #2505642 for closed

center systems (see page 32 for location).

Escaping hydraulic fluid under pressure can pene-

trate the skin, causing serious injury.

DO NOT use your hand to check for leaks. Use a

piece of cardboard or paper to search for leaks.

Stop engine and relieve pressure before connecting

or disconnecting lines.

Tighten all connections before starting engine or

pressurizing lines.

If any fluid is injected into the skin, obtain medical

attention immediately, or gangrene may result.

ASSEMBLY 

(continued)

——————————————————

Check the hydraulic hose routing and connections as

shown in Figure 6. The hydraulic cylinder circuit that
swings the stump grinder left to right has a pressure relief
valve to control the side pressure. Connect this relief
valve as shown.

Use a good thread sealant. (

DO NOT USE TEFLON

TAPE 

as this could cause hydraulic system problems in

your tractor.)

The hydraulic circuits for both cylinders contain an

orifice to provide a controllable rate of movement (#8).

GEARBOX OIL FILL

——————————————————

NOTE:

The gearbox is shipped WITHOUT lubricant, so it

will be necessary to fill it before use. With the gearbox in
a level position, fill to the side inspection hole with a good
90 wt. gear lubricant. Check often and add lubricant if
necessary.

GEARBOX OIL CAPACITY

Model SG-26     2 pints
