Suspensions & Brakes
LUBRICATING THE WHEEL BEARINGS
Every 2 Years
In normal operating conditions, lubricate the bearings every 2 years or every 50,000 km and when
the brake shoes are replaced.
In harsh conditions the bearings should be lubricated more frequently.
Use a general purpose EP grease formulated for lubricating plain, ball and roller bearings, subject
to heavy loads and impacts typical of HGV, agricultural vehicle hubs, etc.
All parts (hub, spindle, bearings, seals, castle nuts, hubcap, cotter pin) should be degreased and
Perfectly clean before reassembly.
The work should be carried out in a clean environment with appropriate tools as the slightest bit
of dirt can
Damage the bearings or even the spindle.
When carrying out maintenance on the bearings, check the brake linings, drum and return
springs, clean the brakes, clean and lubricate the brake cam shaft.
BRAKE MAINTENANCE & ADJUSTMENT
Initial checks
The brakes should be tested before using for the first time and after the first laden journey:
Check the actuator and return spring mountings, check the actuator stroke and return travel
and check that the road and parking brakes operate and release correctly.
Tighten the screws and nuts (covers, fulcrum, etc), check the cotter pins, pins, circlips, etc.
Check for hydraulic fluid and air leaks.
