We have an L20D that won't move.the steering and bucket work but it just tries to turn the wheels about two inches. It worked fine a month ago but now it seems like it is locked up. Any ideas?
Did it drive then you parked it up and now won't, or drove it along and something is now preventing it moving? anything on the display any odd noises? Below is suggestions from Volvo Possible cause of malfunction Malfunction repair Oil level in hydraulic oil reservoir too low Check hydraulic oil level, top up if necessary Suction line broken, bent or leaking Check suction line and connections on hydraulic oil reservoir, tighten connections or replace if necessary Suction return filter dirty Change filter Connection on hydraulic adjustment pump defective Check pressure for forward and reverse travel, working and steering hydraulics, replace connection if necessary Feed pump defective or provides insufficient pressure Check feed pressure, change pump if necessary High pressure valve, forward and reverse motion faulty or dirty Check pressures at high pressure valves forward and reverse motion, adjust or replace high pressure valves if necessary Selector magnets for adjustment, forward and reverse motion do not select Check current or voltage, test selector pistons mechanically Controller cartridge faulty Test start up speed Disconnection valve faulty Check or adjust and if necessary change disconnection valve Intake panel Ø 1.8 mm (0.07 in) or outlet panel Ø 0.8 mm (0.03 in) dirty Check control pressure X1 and X2, where applicable remove and clean inlet and outlet panels. Inch device fully used Check return spring and stop, adjust and replace if necessary Drive hydraulics adjustment motor faulty Check for oil leaks Connection of drive hydraulics adjustment motor to transmission faulty Check connection, change if necessary
It drove when we parked it. Now it tried to move about two inches and stops.
Pull the brake pedal up by hand. Clean any dirt from around it as well. Lube up the pivot pin as well. Make it so it moves really easy up n down
The first thing I did last week when it wouldn't move was to eliminate my brake linkage as a cause. Yesterday I found that somehow the brake shoes were seized to the drum. I should be up and running today. hanks guys.
The first inch or so of pedal travel works the declutch or inching valve. It essentially throws the travel pump in neutral. Usually people push a little snow, then the rust holds the pedal. I've never experienced seized shoes on a 20 or 25 before. Glad to see it was an easy fix
