Hydraulic Filter Change; Accessory Belt - Terex DTM 00101 (standard) 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 4.6 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 Belt

The engine uses a serpentine style belt (with auto-tension device) to drive acces-
sories like the alternator, water pump, and cooling fan. Belts stretch and wear
during their service life. The accessory belt on the PT-100G should be visually
inspected daily for tension, condition, and presence prior to operation
To check drive belt:
1. Shut the machine down according to the procedure in section 5.13, allow
the machine to cool thoroughly.
2. Raise the hood at the rear of the machine to access the belt.
3. Visually inspect the belt to make sure it is present, tight around the pulleys
and in good condition.
