About the earlier two yrs we have observed a significant raise in guarantee statements with regard to the Air Processing Models or Air Dryer Models equipped to DAF trucks in the Uk. Most of these statements surface to be in regard of the larger DAFs, particularly the CF85 and the XF95, on the other hand any DAF truck fitted with these Air Processing Models appear to be prone to a claim. Most of the warranty claims that have been submitted to us have been turned down due to intense contamination, particularly oil deposits from the Air Compressor which is the big induce of failure with these units. In an endeavor to fight this challenge the auto company has advised that the Air Dryer unit be relocated together with other modifications, depending on the motor vehicle design to accommodate a more substantial Air Dryer Filter. The outdated filter component range is 1391510 and it is to be replaced by 1681575. This filter, not only decreases humidity going in to the air process but also filters any oil vapour hence cutting down contamination. In my impression this is unpractical, costly to the car or truck operator and does not tackle the authentic difficulty which in the long run lies with the Air Compressor.
There will often be some oil vapour on the other hand too much oil will however get via specially when operators fall short to improve the filters often more than enough. When a DAF Truck demands a replacement Air Processing Unit the Main Seller or areas supplier ought to request that the aged unit be returned and inspected for excessive contamination, nevertheless this could be deemed to be satisfactory if the unit experienced been in company for a amount of years and that any construct up of carbon experienced been bit by bit progressive. The Air Dryer’s silencer, typically is a superior indicator as to no matter if there is surplus oil passing into the air method, a light-weight dusting that is matt in visual appearance is viewed as ordinary while thick shiny deposits would be regarded as irregular. It is also well worth pointing out that any time we have supplied both of those the Air Dryer and Air Compressor with each other no issues were being skilled thereafter. Other operators have acknowledged that their DAFs have quirks, this currently being one, and that if the Air Dryer filters are improved often, challenges rarely occur.
All Pieces suppliers have an obligation to tell Prospects of the possible issues of not making sure that the Air Compressor is of satisfactory problem and that all shipping pipes into the Air Dryer are cleanse and no cost of any obstruction. This also handles the Supplier really should a foreseeable future guarantee claim be manufactured. Unfortunately the price of changing the Air Compressor and Air Dryer is these kinds of that several operators will pick to dismiss the induce (Air Compressor) and replace the challenge (Air Dryer) and although a temporary take care of is realized it is only a matter of time prior to the changed unit is creating difficulties and so the warranty course of action starts.
Therefore the queries are:
Is it a poorly built unit in the to start with location?
Is the Operator carrying out the necessary checks and typical servicing?
Are the Air Tanks being drained on a regular basis?
Are the Auto companies and the Air Brake companies singing from the exact same hymn sheet or is there a change of feeling?
