Hydraulic Filter Change; Accessory Belts - Terex PT-110 F Operation And Maintenance Manual

7.8 Hydraulic Filter Change

The hydraulic filter should be changed every 250 hours. Hydrostatic components
require extremely clean oil in order to have a long service life. Use caution when
changing the hydraulic filter. Before beginning the procedure, make sure the
machine is in a clean working environment. Take any necessary measures to pre-
vent dirt or debris from entering the hydraulic system.
To change the hydraulic filter:
1. Shut the machine down according to the procedure in section 5.13.
2. Allow the machine to cool, then release any residual pressure in the
hydraulic system by following the procedure in section 4.7 of this manual.
3. Lower the forward middle belly pan to access the hydraulic filters (items 2),
as shown in fig. 7.7-2.
4. Clean around the filters, then thread the filters off and replace them.
Dispose of the used filter according to local mandates.
5. Reverse step 3 to complete the procedure.
Note: The machine is also equipped with a filter in the auxiliary circuit case drain
line. It protects the main hydraulic system in the event of catastrophic failure in
an attachment. This filter is designed to last the life of the machine unless an
attachment equipped with a case drain has a drive motor failure during use. (item
3 fig. 7.7-2)
Note: Should a hydraulic hose or fitting need to be removed for maintenance or
service, always inspect it for damage prior to re-installation. If none is found it
may be reused; if damaged, replace.

7.9 Accessory Belts

The engine uses belts to drive accessories.
The accessory belts should be visually
inspected daily for tension, condition and
presence, prior to operation.
To check the belts:
1. Shut the machine down according to
the procedure in section 5.13, allow
the machine to cool thoroughly.
2. Raise the hood and open the side panels at the rear of the machine.
3. Visually inspect the belts to make sure they are present, tight around the
pulleys and in good condition.
To set tension on the main accessory belt (A/C belt tension is not adjustable):
1. Loosen the clamp bolt (7) and the jam nut (6) on the tension bolt, then
tighten the tension bolt until the slot in bracket (8) is bottomed on clamp
bolt (7) as shown (fig. 7.9-1). Tighten items 6 & 7 to secure.
Once tension is set (main belt only), if either belt appears loose, or is cracked or
damaged, replace it.
