Hydraulic Filter Change; Accessory Belt - Terex TSV-70 Operation And Maintenance Manual

7.8 Hydraulic Filter Change

The hydraulic filters 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 filters. 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. Open the hood and rear door to access the hydraulic filters (items 2, 3), as
shown in fig. 7.7-2.
4. Clean around the filters, then thread the filters off and replace them.
Dispose of the used filters according to 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 4 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 Belt(s)
The engine uses a belt(s) to drive accessories like the alternator, water pump, and
cooling fan. Belts stretch and wear during their service life. The accessory belt(s)
on the TSV-70/80 should be visually inspected daily for tension, condition, and
presence prior to operation
To check belt(s):
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 door at the rear of the machine to access the
belt(s).
3. Visually inspect the belt(s) to make sure it is present, tight around the
pulleys and in good condition.
