2024 FORD F650/750 maintenance schedule

any air tanks equipped with automaticmoisture ejector valves, as required, tomaintain a dry air system. Contact anauthorized dealer if you are unsure of theair reservoir locations or the drainingprocedure.
Hydraulic Brakes
Establish a regular schedule for periodiccleaning, lubrication and adjustmentinspection based on vehicle use. Exactmaintenance intervals are difficult topredetermine due to vehicle applicationsand operating conditions. If you areuncertain of the proper schedule for yourvehicle, contact an authorized dealer.
Regular inspections should include:
•Checking the brake lining (every serviceinterval). Establish inspection intervalsthat provide for lining replacementbefore damage to the disc occurs.Excessive lining wear may expose thebacking plate to the disc causingscoring of the disc faces. A qualifiedtechnician should perform this
inspection and keep to instructionsprovided by the service manual.Hydraulic brake systems arepower-assisted. There is a greatreduction in braking capabilitieswithout engine assist.
•Proper fluid level. The level should beat the bottom edge of the ring on eachreservoir fill port. Do not fill the mastercylinder to the top of the reservoir. Iffluid level requires attention tomaintain a proper master cylinder level,this is an indication of either severeoperation (pad wear) or fluid leakage.A more frequent and thorough brakeinspection is required.
•Brake lines, hoses and fittings. Repairor replace brake line tubes, hoses orfittings as required. Inspect thesecomponents every 4,000 mi(6,000 km) for the following.
•Lines for kinks, dents, corrosion orrupture.
•Hoses for abrasions, kinks, softspots or rupture, collapse, cracks,twists or loose frame supports.When replacing a hose, be surethere is adequate clearance to thehose to avoid an abrasion to thenew hose.
•All connections for leaks.
Driveline Parking Brake
WARNING: Use wheel chocks andexercise caution when inspecting underthe vehicle. A vehicle roll-away couldresult in property damage, personal injuryor death.
A qualified technician should adjust theparking brake and keep to the instructionsin the service manual.

AXLE INSPECTION
Front Axle
Maintaining the front axle alignment tospecifications is very important. A qualifiedtechnician should check and maintain thealignment.
Regular inspections should include:
•Toe-in inspection and adjustment (ifnecessary), particularly with radialtires.
•Checking for proper tightness of axlemounting U-bolt nuts, attaching ormounting bolts and nuts.
•Checking the axle for damage, binding,worn parts and adequate lubrication.
•Checking the kingpins for excessivewear. Also, perform this check duringother scheduled maintenance, forexample as tire rotation or service,wheel bearing service and alignment.See the workshop manual for properprocedures.
Toe-in
It is essential to maintain correct toe-inand tire pressure for optimum tire wear.
Inspecting steer axle tires in the first3,000–10,000 mi (5,000–16,000 km)generally shows if tires are wearingnormally.
Rapid outside shoulder wear on both tiresindicates too much toe-in.
Rapid inside shoulder wear on both tiresindicates too much toe-out.
In P&D-type service, there can be aleft-to-right steer tire tread life differentialup to 40% depending on routes and othervariables.
Follow the tire manufacturer'srecommended cold inflation pressure forthe tire size, load range (ply rating) andsteer axle loading typical for their operation(each steer axle tire equals ½ steer axleloading).
Special applications may warrant a settingbased on experience with the type of tireoperating loads and conditions. Radial tiresare more sensitive to toe-in setting thanbias ply tires. Fine tuning school busalignment to line-haul truck standardsdoes not drastically improve tire tread life.
STEERING SYSTEM
INSPECTION
WARNING: Failure to maintain thesteering system in proper condition cancause reduced steering ability resultingin property damage, personal injury ordeath.
Note:Have any steering problemsimmediately corrected by a qualified servicetechnician.
Ask your service technician to examine thesteering mechanism. Only minoradjustments may be necessary.
Regular inspections should include:
•Checking the tie rod, drag link endclamp bolts and ball joints for propertightness.
•Checking for installation and spread ofcotter pins and tightness of nuts atboth ends of the tie rod and drag link.
•Checking that the pitman arm (steeringarm at steering gear) mounting is tightand locked. Check system for leaks orhose chafing. Repair immediately, ifnecessary.

Your vehicle can be driven in such a waythat dilutes and increases the level of oilby short trips that do not allow the engineto get to operating temperature, extendedidling, and low speed driving for longperiods of time.
A message appears in the instrumentcluster display when it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi(800 km) of the message appearing. Makesure you reset the Intelligent Oil-LifeMonitor after each oil change. SeeInstrument Cluster (page 64).
If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5,000 mi (8,000 km) fromyour last oil change. Never exceed one yearor 10,000 mi (16,000 km) between oilchange intervals for gas engines.
Never exceed one year or 15,000 mi(24,000 km) between oil change intervalsfor diesel engines.
Your vehicle is very sophisticated and builtwith multiple, complex, performancesystems. Every manufacturer developsthese systems using differentspecifications and performance features.That is why it is important to rely upon yourdealership to properly diagnose and repairyour vehicle.
Ford Motor Company has recommendedmaintenance intervals for various partsand component systems based uponengineering testing. Ford Motor Companyrelies upon this testing to determine themost appropriate mileage for replacementof oils and fluids to protect your vehicle atthe lowest overall cost to you andrecommends against maintenanceschedules that deviate from the scheduledmaintenance information.
