many of the issues raised at the conference were illustrated by the wares on show. Bendibt, Clayton Dewandre and Intercare all had stands displaying remanufactured brake actuators, but anyone attending the conference would have heard the reasons why one or other provides the best service.
While retreading or regrooving was being discussed, a demonstration of re • grooving could also be seen at the exhibition. Across the way an example of the new Beans Dieselmaster range of remanufactured engines was also on display. Diesel anti-waxing additives were not popular with the panel of experts, but the stand selling Add-Itt anti-waxing additive had a list customers sufficiently satisfied to repeat orders.
Parts under discussion Raychem, which makes the Thermoline fuel heater had a stand, where it found it was the right time of year to interest operators in the product. Lucas CAV showed a neat fuel heater that fits between the fuel filter and the fuel filter mounting, like a heated collar. The kit includes all the wiring, and the longer stud necessary to allow for the space taken by the heater, and is easy to install.
A further device to improve the winter performance of the diesel engine is the Dieselstart gjowplug, also found on the Lucas CAV stand. For engines that refuse to start for more fundamental reasons, the Perkins Powertune, which is described in greater detail elsewhere in this issue, could give a clue as to the reason why.
For the operator or workshop that reconditions engfmes, Dave Hadley Engineering showed a range of equipment, made by Mira of Switzerland, that will bring the top end of any engine back to health. A valve seat cutting, tool, which uses the valve guide as a centring register in the usual fashion, but recuts the three angles of the seat. This avoids the overwide seat that can occur after recutting, and the accuracy of the machine was demonstrated by a vacuum gauge, that demonstrated that the valve sealed without being ground in.
Engines that lose compression through leaking liners can have the counterbores in the cylinder block refaced in situ with the Mira BB. It clamps to the surface of the block with a powerful eletromagnet, and has a simple centring device, but is hand powered. It can also be used to reface the sealing rings on aluminium and iron cylinder heads.
Every one who spoke about rernanufacturing stressed how the parts are cleaned, and there were various cleaning machines on show at the exhibition. Metalas and Ardrox both demonstrated washing machines, which work on the rotary principle.
For more stubborn dirt, and harder components, Pangbom showed a selection of parts that had been cleaned by one of its Centriblast machines. A wide range of machines, the Centriblast can clean components held on a table, hung from a hook, tumbled on a belt, or carried through on a roller conveyor.
Equipment for the repair of the most vital part of the commercial vehicle, the load space was seen on the Jaggards stand. Replacement parts, as well as the equipment needed to repair curtains was shown, with demonstrations being done on the stand.
The exhibition showed the wealth of equipment, parts and services available to the workshop manager in his quest to keep his vehicles running reliably and economically. An essential event for both exhibitor and visitor, the Workshop exhibition is seen by all as a worthwhile contribution to the road haulage calendar.
