3.11 Towing (Hydrostatic Pump Adjustment)
When towing the Articulator, it is necessary to make minor adjustments to both of the
hydrostatic pumps. This will allow the hydraulic fluid to bypass the hydrostatic pump.
Please follow the instructions below for the proper procedure:
1. Locate the bypass valve. This will be located on the side of each pump. NOTE: The
bypass valve is zinc plated with the hole drilled through the sides.
2. Use a 5/8” wrench to turn the valves no more than (2) two turns in a counterclockwise
motion. The drive tires should rotate freely.
3. Tow the unit to the desired destination at a slow speed.
4. When towing in completed, return the valves to there original position by turning them in a
clockwise motion until they are tight (84-120 in-lbs).
3.12 Hydrostatic Pump Belts
Warning
WARNING!

NEVER inspect, adjust, or change the hydrostatic pump belts while the engine is
running!
The hydrostatic pump drive belts are located under the operator seat pan, between the
engine main drive pulley and the hydrostatic pumps both to the left and right of the
engine. Each pump mount pivots away from the engine at the frame above the pump. The
tension springs located under each pump tensions the belts to the proper level.
Check the belts for visible wear or damage. If either belt appears excessively worn, dam-
aged, cracked, weathered, or otherwise appears to pose an unsuitable or unsafe operat-
ing condition, replace the belt.
When the belt is properly tensioned by the tension springs, the pump should orient
square to the frame. If this is not the case, such as the pump pivots excessively past
square, or comes into contact with any peripheral apparatus, you must replace the belt. If
the belt you are checking is new, and the pump pivots excessively past square, or comes
into contact with any peripheral apparatus, it is likely you have installed the wrong size
belt. Contact your Lastec dealer for the proper belt lengths for your Articulator.
If you are unable to install a new belt with the pump pivoted to its closest proximity to the
engine drive pulley, it is likely you are installing the wrong size belt. Again, contact your
Lastec dealer for proper belt lengths for your Articulator.
