Quicke Q 20–85 Series Common Problems This Manual Covers
Quicke Q20 front loader arms drift down after parking tractor and will not hold position under load p. 43
Inspect the lift cylinders for internal leakage. Refer to page 43 for internal leakage rates. Replace worn piston seals if leakage exceeds allowable limits. Verify the system does not exceed the maximum hydraulic pressure of 2100 Mpa to prevent premature seal failure.
Manual Section: Trouble shootingFront loader does not raise or raises very slowly when operating the main control valve p. 24
Check the control cable connections at the hydraulic valve. Tighten the small control cable screws to exactly 5-6 Nm as detailed on page 24. Verify the tractor hydraulic supply is delivering adequate flow and bleed any trapped air from the lift circuit.
Manual Section: InstallationImplement quick coupler mechanisms sticking and difficulty fully connecting or removing bucket attachments p. 76
Clean dirt and contamination from the attachment interface and coupling system. Inspect the locking mechanism parts for wear. Torque the Lock & Go screws (Item 5) to 22 Nm as shown on page 76 to ensure proper linkage alignment during implement connection.
Manual Section: AccessoriesLoader suspension feels overly stiff or fails to cushion bumps during heavy transport operations p. 62
Test the loader suspension accumulators for proper gas charge. If operating a single accumulator system, verify the accumulator pressure is at exactly 15 bar as specified on page 62. Inspect the Softdrive electrical kit and tighten mounting hardware to ensure secure connections.
