Remove loader end attachment (such as a shovel) if
fitted. If the attachment is hydraulically operated,
disconnect attachment hoses and plug/cap
immediately. Vent residual hydraulic pressure prior to
removing hoses by operating the control levers with the
engine switched off.
! WARNING
DO NOT work under raised loader arms unless they are
adequately supported by stands and/or slings.
BF 3-1
3
Remove the engine panels, refer to Section 3 Routine
Maintenance – Engine Panels.

5
Sling the loader arms as shown at X. Make sure that
the slings are taut and therefore holding the weight of
the loader arms.
6
Switch off the engine and vent residual hydraulic
pressure from the loader end by operating the loader
controls back and forth several times.
7
Remove the lift ram pivot pins A.
Note: Care must be taken when removing the lift ram pivot
pin, once the pin is removed the ram will drop. Either hold
the ram using a sling or have a second person hold the ram
before removing the pin.
8
Lower the loader arms to the ground using the slings, it
may be necessary to retract the lift rams to enable the
loader arms to rest fully on the ground. Make sure the
lift rams do not foul when retracted.
9
Make sure residual hydraulic pressure has been vented.
Disconnect the shovel ram and auxiliary (if fitted) hoses,
shown at B. Plug and cap the hoses immediately.
10
Disconnect the electrical connections (not shown) to
the loader shovel reset switch (if fitted).
11
Remove pivot pin retaining bolts D, E, F and G.
12
Sling the loader arms as shown at Y. Make sure that
the sling is wrapped around the loader arms only and
not the level links.
13
Remove klipring H and shim K.
! WARNING
The loader arm interlevers are potentially dangerous,
when pivoting about their centre they form a ‘scissor’
point with the loader arm. Make sure the interlevers are
securely blocked when working in the loader arm area.
BF 2-1
14
Secure the interlever lever linkage as shown at Z,
otherwise with level link pivot pin L removed, the
interlever linkage could pivot about its centre and
cause injury and/or damage.
15
Remove pivot pin L (use slide hammer kit, service tool
993/68100).
16
Repeat steps 13 to 15 for the opposite level link pivot
pin.
17
Remove bolt T and retaining ring R.
18
Remove pivot pin U (use slide hammer kit, service tool
993/68100)
19
Repeat steps 17 and 18 for the opposite loader arm
pivot pin.
20
When all four pivot pins have been removed, carefully
reverse the machine clear of the loader arms
Replacement
Replacement is a reversal of the removal sequence.
Fit pivot pins with the extraction hole on the outside of the
machine.
Check operation of loader shovel reset switch (if fitted).
Apply grease to all mainframe bores.
Apply rust inhibiting oil to all pivot pins.
If fitting new liner bearings, assemble with a close fitting
shouldered mandrel to ensure minimum ovality.
