Maintanance - How to purge Hydraulic drive system Published 01/13/2010 11:56 AM ' Updated 06/02/2015 02:52 PM
How do I purge the hydraulic system?
Hydrostatic transmissions use oil, under pressure, to provide movement for the tractor. The fluid is pressurized with a pump inside the transmission. If any air is in the fluid, the pump will try to pressurize air. This condition is known as cavitation, and is detrimental to the pump since it allows the pump top operate dry. When the pump cavitates it is not pressurizing any fluid, so the transmission is not able to provide the movement needed.
If your mower is new, or has been stored for a long period (longer than 2 months) the transmission needs to be purged before use. Also, if you experience loss of drive, or slower response, then the transmission should be purged first.
The following procedure will remove trapped air inside the transmission(s).

IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.
Step 1- Place the rear of the mower safely onto jackstands on a level surface with engine off and parking brake set.

Step 2- Disengage transmission by placing freewheel control, located at the back of the frame, in the freewheeling position.

2a- Mowers with seperate pumps and wheel motors the freewheel is activated by turnign the bypass valves, one on each pump, two full turns.
The oil resevoir needs to be filled to the specifications listed in the owners manual before starting the purge procedure.
Step 3- Sitting in the operators seat(riders), start engine. After the engine is running, move throttle control to slow position. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.
Step 4-Move motion control levers to full forward position and hold for five (5) seconds. Move levers to full reverse position and hold for five (5) seconds. Repeat this procedure three (3) times.

NOTE: During this procedure there may be some movement of the drive wheels, but they are not under load. The air is being removed from hydraulic drive system.

Step 5-Move motion control levers to neutral (N) position. Shutoff engine and set parking brake. Check and add oil as needed for units with an oil resevoir.

Step 6-Engage transmission by placing freewheel control into driving position, or by closing the bypass valves on the pumps.
Step 7-Sitting in the operators seat, start engine. After the engine is running, move throttle control to full speed. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.

Step 8-Slowly move motion control levers forward, after the tractor moves approximately five (5) feet, slowly move motion control levers to reverse position.
After the mower moves approximately five (5) feet return the motion control levers to the neutral (N) position. Repeat this procedure with the motion control levers three (3) times.

Step 9-Your mower is now purged and now ready for normal operation.For further information or assistance, we recommend contacting your lo

You don't adjust it yourself, contact Authorized Service Station and they'll adjust it for you.

Jack up and support the bike with the front wheels off the ground. Yours might possibly be a different size but my 07' has a nut on the left side of the wheel that takes a 15/16" wrench. I would use a boxed end wrench or socket to avoid rounding off the nut.
On the bottom of the right side fork tube you will find two bolts holding a cap on. After loosening the nut on the left side of the wheel, loosen the bolts in the cap.
On the end of the axle you should find some holes that go through the axle. Use a long punch or rod that will fit inside the holes, using a twisting motion, pull the axle out. Make sure you remove the brake caliper before pulling the wheel.

I have noticed this problem on various different vehicles...after you turn the car off and pull the key out, physically force the wheel to the right or left really hard...the wheel will lock. It just happens to not be in the correct position for the locking mechanism to engage where you last left the steering wheel...to experiment with this, try turning it back on, and turning the wheel just slightly to one side or the next and repeat until you find the "spot" that it engages easily...hope that helped

You probably answered your own question, the belt is the first thing i would check

The fuel pump is usually located in/on the fuel tank, but with your jag, it is mounted externally from the tank. Frame mounted design with an inlet and outlet fitting...

Jack up the rear left hand side. Put the car on axle stands. Remove the left hand rear wheel.

You should be able to follow fuel line back to the fuel filter (just forward of the wheel arch) and then to the fuel pump which is behind wheel arch, (before the rear silencer/muffler).

One thing though, you might just have a faulty fuel pump relay, which on your 1990 can be found in the engine bay, left side, attached to the brake pedal hanger.

If you do decide to remove the fuel pump after all, then depressurize the fuel system first.

Remove fuel filler cap, disconnect the fuel pump relay, start engine and wait for it to stall. Turn off ignition, then disconnect battery.

Take all the usual precautions before disconnecting fuel lines, rags, container to catch spilt fuel etc.

Hope that helps, please rate me too thanks!

The below are improvements over the years. One thing to remember that a HUGE % of the energy the rider puts into moving forward is used to overcome wind resistance.

In terms of motion....

Lighter overall. Lighter bikes overall, lighter wheels - easier to spin up and keep rolling.

More efficent bearings all around/ wheels cranks, etc.

Better design of frames/bars, etc. Positions the rider better on the bike to convert his energy into forward motion Also - better positions the rider on the bike to cut the wind better - lower rider resistance.

better tires, skinner tires - Less rolling restiance -
