6.5.4 After Transmission Service or
Replacement
Refer to the Dana Spicer Transmission Repair Manual
which can be obtained by calling your local JLG
Distributor.
In General:
1. Check the transmission oil level and add oil as
required.
2. Install a new transmission filter.
3. Check the torque on the drive shaft yoke capscrews.
4. Wear suitable eye protection. When an overhauled
or repaired transmission is installed, thoroughly
clean the oil cooler lines to and from the
transmission.
5. Drain and flush the entire system.
6. Disconnect and clean all transmission cooler hoses.
When possible, remove transmission lines from the
machine for cleaning.
7. Thoroughly clean transmission filter screens and
cases, and replace transmission filter elements.
CAUTION:
11,4 bar (165 psi) when back flushing the oil
cooler. Applying too much pressure may
damage the oil cooler/radiator.
8. Back flush the transmission oil cooler portion of the
radiator or the oil cooler (located behind the radiator)
with oil and compressed air until all foreign material
is removed. Flushing in the direction of normal oil
flow does not adequately clean the cooler. If needed,
remove the radiator or oil cooler from the machine.
IMPORTANT: DO NOT use flushing compounds for
cleaning purposes.

the level by taking intermittent dipstick readings as
outlined in the appropriate Operation & Safety
Manual. DO NOT overfill. Reinstall the dipstick when
finished.

the engine running at idle.

12. Add Mobilfluid 424 ISO Grade 46 as necessary to
bring the fluid level up until it reaches the FULL mark
on the dipstick. Recheck the oil level when it reaches
operating temperature 83-94°C (180-200°F).
13. Recheck all drain plugs, lines, connections, etc. for
leaks, and tighten where necessary.
