DAF 95XF Maintenance Manual

The vehicle components are provided with threaded connections, which have been treated with lubricant (dipped threaded connection). Factory-galvanised bolts and nuts are wax-dipped. 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 and accurate torque wrench.

To achieve the correct pre-tension when re-using threaded connections, it is important to clean the threaded parts thoroughly. After cleaning, apply one drop of lubricant to the first turn of the screw thread and one drop to the abutting surface of the nut or bolt. If bolts and nuts to be re-used, do not lubricate them with anything other than engine oil. Lubricants other than engine oil or factory-applied lubricant must not be used under any circumstances because of the difference in frictional coefficient.

The following applies to all threaded connections (for both new and used vehicles):

  1. in the case of standard connections, apply the lubricant before fitting, and retighten in accordance with the standard for dipped bolts.
  2. in the case of special connections, apply the lubricant before fitting, and retighten in accordance with the values specified in the instructions.

The instructions for using a lubricant also apply to new bolts supplied from the warehouse. Dry threaded connections are not permitted because of their highly variable friction coefficients.

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

The technical information in this maintenance manual, such as notes on maintenance activities and technical data required to carry out the maintenance activities in a responsible manner, was up-to-date at the time this manual went to press. DAF reserves the right to make changes without prior notice.

Note:Important changes relating to technical information which are not contained or could not be contained in this maintenance manual will be published in a TI (Technical Information Sheet).

Removing the hub oil seal

  1. Remove the hub from the axle journal.
  2. Drill two holes into the oil seal and screw the special tool (DAF no. 0484899) into the oil seal. Pull the oil seal from the wheel hub using the special tool (DAF no. 0694928).

Installing the hub oil seal

  1. Check the seal chamber for damage.
  2. For installation of the hub oil seal (4) use special tool (DAF no. 1329497).
  3. Apply a little grease to the sealing lips of the oil seal.
  4. Install the hub on the axle journal.

Before cleaning the vehicle, check the engine, axles, gearbox, etc. for evidence of leakage. Having cleaned the vehicle, it will no longer be possible to check for leaks during the maintenance activities.

Make sure that doors, windows and roof hatch are securely closed during cleaning. When cleaning the universal joint on the steering box, the spider seals may be forced open by the high-pressure jet of water, so that the grease behind them is flushed away. As a result, the spider may get stuck, so that the steering will “jam”. A bleed screw is fitted to the power steering fluid reservoir of the steering gear. Water may enter the power steering reservoir via the vent, which will cause damage to the steering gear.
