Driveline Maintenance
Before each use, check that the driveline is securely
fastened and that all driveline shields are in place,
undamaged and in working order. Replace driveline and
shields as needed. Order only genuine Land Pride parts
from your local Land Pride dealer.
DANGER
!
To prevent serious injury or death:
•
Tractor power take-off shaft shield, driveline shields, and
gearbox shaft shields must be installed and in good working
condition to avoid driveline entanglement and projectiles
flying off of the driveline.
•
Always disconnect driveline from the tractor before
servicing the drivetrain and components powered by the
drivetrain. A person can become entangled in the drivetrain
if the tractor is started and the power take-off is engaged.
WARNING
!
To prevent serious injury or death:
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
•
Do not operate a broken or bent driveline. Such a driveline
will break apart while rotating at high speeds. Always
remove the implement from use until the damaged driveline
can be repaired or replaced.
Slip Clutch Protected Driveline
The purpose of the slip clutch is to protect the drivetrain
from shock loads.”To do this, the clutch must be capable
of slippage during operation. To verify the clutch will slip,
a “Clutch Run-in” operation must be completed.
WARNING
!
To avoid serious injury or death:
A slip clutch that has been in use or has slipped for as little as
only two or three seconds during run-in may be too hot to
touch. Allow a hot clutch to cool before working on it.
IMPORTANT:
Prior to initial operation and after 30
days of inactivity, slip friction disks to remove
oxidation and moisture. Moisture allows disks to slip
easily. Oxidation can prevent disk from slipping
causing driveline damage. This damage is NOT
covered under the warranty.
Clutch Run-In
Figure 4-2
Clutch Run-In
Refer to Figure 4-2:
Friction clutches should be “run-in” prior to initial
operation and after long periods of inactivity to remove
any oxidation that may have accumulated on friction
surfaces. To prevent driveline and gearbox damage,
repeat “run-in” instructions at beginning of each season
and when moisture and/or condensation seizes inner
friction disks.
1. Using a pencil or other marker scribe a line across the
exposed edges of the clutch plates and friction disks.
2. Carefully loosen each of the 8 spring retainer nuts by
exactly 2 revolutions. It will be necessary to hold the
hex end of the retainer bolt in order to count the exact
number of revolutions.
3. Start the tractor and engage the driveline drive for
2-3 seconds to permit slippage of the clutch
surfaces. Disengage the driveline, then re-engage a
second time for 2-3 seconds. Disengage driveline,
shut off tractor, and remove key. Wait for all
components to stop before dismounting from tractor.
4. Inspect the clutch and ensure that the scribed
markings made on the clutch plates have changed
position. Slippage has not occurred if any two marks
on the friction disk and plate are still aligned. A clutch
that has not slipped must be disassembled to
separate the friction disk plates. See “Clutch
Disassembly”
to disassemble clutch.
5. Tighten each of the 8 spring retainer nuts on the
clutch housing exactly 2 revolutions to restore the
clutch to the original setting pressure.
6. The clutch should be checked during the first hour of
operation and periodically each week. An additional
set of scribe marks can be added to check for
slippage. See “Clutch Assembly” to adjust for
proper spring length.
