What to do if Holland Other legs are locked and will not turn?
If the Holland landing gear legs are locked and won't turn, inspect the landing gear for any signs of impact damage. Disconnect the cross shaft and try cranking each leg separately to find out which one is damaged. You may need to replace the entire retract assembly or the damaged leg.
Why is Holland Other hard to crank under load?
If the Holland landing gear is hard to crank, especially under load, it might be due to a damaged collar or thrust bearing. Try replacing the collar or the thrust bearing.
What to do if non-gearbox leg operates, but gearbox leg of Holland Other does not?
If the gearbox leg of your Holland landing gear isn't operating while the opposite leg is, the bevel gear pin or pinion gear pin might be sheared, or the bevel gear or pinion gear could be damaged within the gearbox leg. Remove the upper leg cover and inspect for damaged or missing pins under the bevel gear or in the pinion gear. Also, check the gears themselves for damage and replace any affected components.
What to do if gearbox leg operates but opposite leg of Holland Other does not?
If the gearbox leg of your Holland landing gear is operating while the opposite leg isn't, it could be due to a broken or damaged cross driveshaft bolt or the cross driveshaft itself. It could also be that the bevel gear pin or pinion gear pin is sheared in the non-gearbox leg, or the bevel gear or pinion gear is damaged. Replace the cross driveshaft bolt or the cross driveshaft if needed. Otherwise, remove the upper leg cover and inspect for damaged or missing pins under the bevel gear, or in the pinion gear and replace as necessary. Also, check the gears themselves for damage and replace any affected components.
What to do if both legs of Holland Other will NOT operate, but shift shaft and output shaft turn?
If both legs of the Holland landing gear will not operate, and the shift shaft and output shaft turn, it could be that the bevel gear pin or pinion gear pin is sheared in both legs, or the bevel gear or pinion gear are damaged in both legs. Remove the upper leg covers and check for damaged or missing pins under the bevel gear, or in the pinion gear and replace if needed. Inspect gears for damage and replace if needed.
What to do if both legs of Holland Other will NOT operate, shift shaft will turn but output shaft DOES NOT turn?
If both legs of your Holland landing gear will not operate, but the shift shaft will turn but the output shaft does not turn, the input, idler, and/or output gear may be damaged, or gear pins may be sheared in the gearbox. Remove the gearbox cover to inspect and replace any broken gears or pins.
Why does Holland Other crankshaft jam or skip while turning?
If the crankshaft of your Holland landing gear jams or skips while turning, the inner leg screw might be damaged, or the gears could be worn, broken, or damaged. Examine the lift nut and screw of the inner leg assembly for any signs of impact damage. Also, inspect the pinion, bevel pinion, and all gearbox gears for missing teeth or other signs of damage or wear. Replace components as necessary.
