New Semi Truck – Classic Semi Truck

Over the past two years we have seen a considerable increase in warranty claims with regard to the Air Processing Units or Air Dryer Units fitted to DAF trucks in the UK. Most of these claims appear to be in respect of the larger DAFs, namely the CF85 and the XF95, however any DAF truck fitted with these Air Processing Units seem to be susceptible to a claim. Most of the warranty claims that have been submitted to us have been rejected due to severe contamination, namely oil deposits from the Air Compressor which is the major cause of failure with these units. In an attempt to combat this problem the vehicle manufacturer has recommended that the Air Dryer unit be relocated along with other modifications, depending on the vehicle model to accommodate a larger Air Dryer Filter. The old filter part number is 1391510 and it is to be replaced by 1681575. This filter, not only reduces moisture going in to the air system but also filters any oil vapour thus reducing contamination. In my opinion this is unpractical, costly to the vehicle owner and does not address the real problem which ultimately lies with the Air Compressor.

Let’s say you bought a nice old truck and a few months later you noticed that little rust bubbles have formed under the paint, around one of the corners of your windshield.

Then you do an inspection of the whole truck and find more bubbles in the fenders, in the body and under the cab. What do you do?
