Modern Lubricating GREASE has been described Methods Mean as a Most awful material Cleaner Floors . . to have around a garage, although, obviously, not when it is in suitable containers, but where it exudes from vehicles and spreads over the floors. Synthetic rubber is now playing a large part in preventing such exudation, rubber shackles, for instance, removing altogether the need for grease or oil, it is essential, however, to use rubber in compreSsion where it has to bear severe loads, such as in spring shackles, otherwise severe pressure at one point may displace the material and, eventually, result in metallic contact. However, development in this direction is proceeding apace, and the number of points to be lubricated is becoming steadily smaller in modern chassis. Cleanli-.ness is also being assisted by better methods of lubrication, such as those in which a special pump . with multiple feeds is employed, and in which the supply of lubricant to every point car,,be accurately adjusted. No doubt the older system, by which as much lubricant as possible is forced into a bearing A26 and most of it eventually wasted, will gradually be displaced. It had, however, one good feature, that was that the ejection of the oil or grease resulted in any dirt also being forced out—but it should never have entered!
Are Torque Wrenches Good for General Work?
WE were rather interested " the other day, while visiting an engineering works where power units are overhauled, to learn that for some time the company had supplied to its fitters special wrenches which worked on the controlled-torque principle, but had given them up This type of spanner, which can be equipped for hand or power operation, will screw up a nut to a desired degree of tightness. Apparently, however, It was found preferable to allow skilled mechanics to " feel " the degree required, particularly in connection with main bearings and big-ends. Yet we know of large works where this type of device is used with most satisfactory results, but, in these cases, for mass-production work. What are the Main WE recently asked a young Effects of the Short "mechanic in a works what Week? he thought of the five-day week. Somewhat to our surprise he replied "It suits me fine, but I do not think that the country can stand it." On the other hand, we have found employers who are quite satisfied with the results obtained. In these cases, workers have set to with a will and fully compensated for their free Saturdays. This shows an appreciation which is sadly lacking in some employees elsewhere.
Keeping of Drivers' ECENTLY we referred to
Records Now More 1 1a reminder from the
Important . . . . M.O.T. as to the need for drivers of vehicles operated under A and B licences and defence permits to keep and carry on their vehicles' records of their hours of work, loads, etc. Since the Road and Rail Traffic Act of 1933, this has been a statutory obligation, but was not insisted upon during and immediately after the war; now, however, the police are becoming more active in this respect. The requirement is partly in the drivers' own interest so that they shall have their correct periods of rest and work, and to act as a check on the loading of the vehicles. We would emphasize the importance, particularly at this stage, of including accurate information.
Varnished-card Pages THERE seems to be a cornin Fine New Parts
List petition amongst commer
cial vehicle manufacturers to produce the most elaborate spare-parts lists and service handbooks. Some of those recently received have achieved a remarkable standard of art in printing. Among the latest to be issued is the parts identification chart of MorrisCommercial Cars, Ltd. It is bound with spiral wire and the pages consist of stiff, varnished card. The Morris-Commercial company points out that parts manuals frequently become smudged by grimy fingers, and it is hoped that varnishing will preserve the excellent exploded drawings contained in the book.
