9. Remove Grease zert & adapter to gain access to the
(47) ball bearings, holding the joint together.
10. Rotate the movable ½ of joint and collect the ball
bearings that fall out (you may have to creatively
compress the joint together to disassemble).
11. Separate joint to gain access to O-ring inside (inspect
joint and ball bearing grooves to make sure that it is
not worn too much to rebuild).
12. Lubricate and install new O-ring / rotate and reinstall
(47) ball bearings / install adapter and grease zert
/ rotate and grease fully (400deg High temp) before
installation on unit.
13. Clean all gasket surfaces, check internal plumbing,
and replace O-rings if needed / Return to step (7) to
complete the install.

component Illustrated breakdown section)
Adjusting Pump Neutral on 42 & 90 Series Pumps
1. Pump neutral may need to be adjusted, if the
Hydraulic Motor turning the Asphalt Pump turns
when Etnyre Control system is turned (Off} or is
operated in manual with Rear Pump Control
turned all the way CCW to (Off}. Adjusting is
better with 2 people:1 adjusting and 1 watching
Asphalt Pump Shaft rotation at the rear of
Distributor Truck.
2. Locate adjustment and gather tools to make
adjustment (be careful @ all times Due to live
PTO operation on the pump system).
3. Direction of adjusting neutral screw varies
depending on style and location of Hydrostatic
pump, (normal and correct direction of shaft
rotation is CCW standing @ the rear bumper
looking forward). Loosen jam nut while holding
the allen head adjustment screw, turn screw
slowly in CCW direction, if the pump shaft
speeds up, you are turning it the wrong direction,
turn it only till the pump shaft quits turning.
4. Rev up the engine and verify that pump shaft
does not try to turn, a slight adjustment may be
necessary if it does.
5. Once you are satisfied with the neutral adjustment,
it is recommended to test the (EDC} current to
the Hydrostatic Pump Controller, or (EDC} once
the value is determined, set the DC/Ma value in
the Computer set-up of the Etnyre Control
system under EDC Threshold.
42 Series
Testing EDC Threshold
90 Series
Testing EDC Threshold on 42 & 90 Series Pumps
*Note: EDC pump current in (DC/Milliamp’s) is
measured to accurately set the current needed to
initially rotate and turn the Asphalt Pump shaft, this
is installed and entered into the computer setup screen
Threshold MA =) once it is measured, current range
should be: (10.0 -19.0 Dc/ma
)
1. Install Service adapter # 3371084 @ pump connector
(easiest and fastest) or install your meter in series
across any connection that you will have to dismantle
to connect to the power wire between rear control
box pump activation relay and the pump EDC
connector.
2. Once connected, operate pump system in (LOAD)
on manual mode with Pump Control pot turned full
ccw or (Off) meter should read (6.0 -9.0Dc/ma)
3. Rotate Pot (cw) to increase current and stop when
the Asphalt Pump shaft just starts to turn (ccw).
4. The current measured on your meter at this point is
your EDC Threshold reading, should be between
(10.0 & 19.0 Dc/ma)
5. If the EDC Threshold is not within those #s, or is
turning (CW) for any reason, the pump neutral may
have to be adjusted to properly set the EDC
Threshold. Refer to Adjusting Pump Neutral
procedure section of this manual .
