In the article, we will consider possible malfunctions of the steering of a Gazelle car and troubleshooting methods
Possible steering problems without power steering
- Cause of malfunction
Remedy
Increased steering wheel freeplay:
- Increased clearance in the engagement of the nut-sector pair
Adjust the engagement of the nut-sector pair
- The appearance of a gap in the propeller bearings
Adjust screw bearing
- Excessive wear of the part of the hinges of the rods and their fastening
Replace worn parts
- Increased wheel hub play
Adjust wheel bearing clearance
- Loosening the wedges of the forks and the nuts of the bipod
Tighten loose nuts
Steering, squeaking or clicking:
- Excessive wear of the screw or shaft-sector, chipping or dents on their surface
Replace screw nut or sector shaft
Weak steering column lock:
- Loosening the column locking mechanism
Adjust column locking mechanism
Increased steering force "heavy steering":
- Kingpin bushing scuff
Replace bushings and king pin
- Turning the king pin bushings in the knuckle bosses
Replace bushings and kingpin
- Pollution of the pivot bearing (when turning the wheels, a creak is heard in the thrust bearing)
Rinse the thrust bearing through a grease gun with a mixture of 50% kerosene and 50% gear oil.
Lubricate the support bearing through the grease fitting until grease comes out from under the seal
Leaking grease from the steering gear:
- Wear or loss of elasticity of the stuffing box and steering gear seals
Replace worn oil seal and O-rings
Steering column play:
- Axial movement of the steering wheel shaft relative to the casings
Replace worn steering column bearing bushings
Diagnosis of malfunctions of the power steering
- Cause of malfunction
Remedy
Constant noise from the pump:
- Worn bearings
Replace bearings
The booster does not work or its efficiency is low (increased effort on the steering wheel):
- The filter in the tank is clogged
Replace the filter (on parts of engines, the filter is replaced with the tank assembly) and, preferably, the fluid
- Flow and safety valves clogged
Flush valves and pump
- The belt slips over the pump pulley
Tighten or change belt
- Liquid of inappropriate viscosity is filled (as a rule, its viscosity is low)
Change Fluid
The steering wheel turns much easier in one direction than in the other:
- Clogging of the hydraulic system
Flush the hydraulic system and booster
- Amplifier defect: destruction of its parts, valve leaks
Replace amplifier assembly
Liquid leak from the system:
- Worn oil seals
Replace oil seals
- Hose cracks, their clamps are loose
Tighten clamps, replace rods
- Leak from under the covers of the amplifier or pump
Replace gaskets, rubber rings
- Leakage through technological holes in the pump casing (squeezed out the plugs)
Press in new plugs or replace pump
- Increased pressure in the system due to the flow valve jamming in the closed position
Repair or replace pump
- Excessive liquid level in the reservoir
Take off excess liquid with a syringe or rubber bulb
Low directional stability at high speed:
- Violation of the adjustment of the bearings of the screw and in a pair of nut-rail - shaft-sector of the steering mechanism
Adjust gaps between parts
