Daft Trukcs CF85 Maintenance Manual

This maintenance manual describes all relevant maintenance activities. It also contains safety instructions, which must be strictly adhered to. Activities not described in this manual, e.g. replacing components, overhaul, fault-finding, etc., are described in the DAF workshop instructions.

This maintenance manual assumes that the mechanic is sufficiently experienced and has had the required instruction or training to carry out these maintenance activities in a safe and responsible manner. The technical data and notes on the maintenance activities have been compiled with the utmost care.

TIGHTENING TORQUES
The tightening torques specified in this paragraph are different from the standard tightening torques cited in the overview of the standard tightening torques. The other threaded connections not specified must therefore be tightened to the torque cited in the overview of standard tightening torques.

When attachment bolts and nuts are replaced, it is important - unless stated otherwise - that these bolts and nuts are of exactly the same length and property class as those removed.

THREADED CONNECTIONS
The components may have threaded connections that have been treated with lubricant (dipped threaded connection). Galvanised bolts and nuts are wax dipped in the factory. Black annealed and phosphatised bolts and nuts are oil dipped. The advantage of using dipped nuts and bolts is that friction during tightening is reduced, so that the specified pre-tension force can be accurately obtained. The tightening torque can be reduced while the pre-tension force remains the same.

To achieve a small spread in the pre-tension force, the dipped threaded connection must be tightened accurately. Therefore, always use a reliable torque wrench that provides a high degree of accuracy.

Re-use of fasteners (bolt/nut/threaded end)

  1. Clean the thread (take particular care to remove locking compound residues) and the clamping faces
  2. Check the thread for damage. To do so, manually screw a new nut/bolt onto the thread to be checked. If the new nut/bolt cannot be fully hand screwed onto the entire thread of the fastener to be checked, the fastener is not allowed to be re-used.
  3. Apply one drop of engine oil to the upper turn of the bolt (threaded end)/lower turn of the nut and one drop to the clamping faces (other lubricants are not allowed).
  4. If a locking compound has been specified, oil should not be applied to the thread.

Lubricant, engine coolant and fuel additives - of whatever type - must not be used except in those circumstances specified by DAF. Always follow the safety instructions below and the instructions that are supplied with the product. Ask your lubricant and fuel supplier(s) whether the products supplied comply with DAF specifications.

Maintenance group classification
Depending on the use to which the vehicle is put, the vehicle is placed in maintenance group I, II or III.

Maintenance group I
Operation on building sites, in quarries, etc.

  1. Operation on unmetalled roads
  2. Traffic in dusty conditions
  3. Sanitation department vehicles
  4. Distribution transport with an annual mileage up to 30,000 km.

Maintenance group II
Urban and regional transport

  1. Distribution traffic in urban areas
  2. Traffic between adjacent villages/cities

Maintenance group III
(Inter)national traffic

  • Long-distance/very long-distance traffic

Extended changing interval
This is the extended changing interval symbol. If the prescribed oil specification and any additional conditions (see specification manual "Fluids and lubricants") are complied with, an extended changing interval may be applied.

Intermediate inspection
This is the intermediate inspection symbol. Intermediate inspections are based on several visual inspections. When an extended changing interval is applicable to the engine oil (X-service), an intermediate inspection should be carried out.

X-service
This is the symbol for an X-service. An X-service is a mileage-dependent maintenance check which consists of changing the engine oil plus a number of visual inspections.

Y-service
This is the symbol for a Y-service. A Y-service is an annual maintenance check consisting of several maintenance activities plus changing of the gearbox and rear axle oil.

MAINTENANCE IN SPECIAL OPERATING CONDITIONS
Contact a DAF dealer/main branch or importer for vehicles used in very specific or heavy conditions. The service intervals can be modified, if necessary, in consultation with the dealer/main branch or importer to fit the appropriate operating conditions.

FIRST SERVICE INSPECTION
The first service inspection should be carried out between the first 7,500 and 10,000 km or at most 8 weeks after delivery of the vehicle, whichever comes first.

OVERVIEW OF MAINTENANCE ACTIVITIES FOR THE FIRST SERVICE INSPECTION

  1. Change the engine oil
  2. Replace oil filter
  3. Change the differential oil
  4. Changing the hub oil
  5. Check components and hose connections for leaks
  6. Check/set the load-dependent control valve, leaf suspension
  7. Adjust the clutch wear indicator circlip
  8. Replace oil filter in fluid flow control valve block of EMAS system
  9. Replace steering gear filter element, if vehicle is equipped with an EMAS system
  10. Retighten hub nut of leading rear axle 09N044 (FTP-type vehicles)
