Valuable Advice on Every Phase of Ford Transport, which will Appeal to the Owner, Driver, and Repairer.

IN THIS series of hints concerning the Ford light _ chassis and ton truck wherever they are employed for commercial purposes, which commenced recently, we propose to deal with the subject from every viewpoint, so that the advice given will appeal to the owner, driver, maintenance engineer, or mechanic. Valuable sources of information viill be tapped for this purpose, and it should be understood that the information given will all be derived from those with a practical and intimate knowledge of the subject.

' We shall welcome for inclusion amongst the hints those which have proved of value to individual users, and will make suitable remuneration for any published. What we desire are the results of practice, and not so-called improvements, which arc but theoretical.

34.--Piston Rings which Prevent Oiling-up.

One of our readers sends us a useful hint concerning some piston rings which he ' has found very efficient in stopping the troubles, so common to the Ford, of oiling-up of the plugs and a smoky exhaust. : He states that. during the past four months he has fitted about 20 Ford engines with what are known as "pressure-proof piston rings," which can be obtained from the American Import Ca., 413, Corn Exchange, Manchester, and that in every case the troubles have entirely disappeared. The construction of these rings can be seen from the illustration. One of the advantages is that there is no need to fil,new pistons ; in fact, in some of the engines in which the rings have been tested the pistons were very slack. We understand the cost is about 3s. per ring.

35.—Examine Your Headlamps.

Always make certain that the front glasses of the headlamps are.right home. TO fasten them they are pushed hard in and turned to the right to lock them in position. If this is not performed in a satisfactory manner they often drop intothe road and May be broken or lost. If the front is rusted into position, tap the four rivets gently all the way round, press the front in and turn to the left to unlock in the usual manner.

In those Fords not fitted with self-starters, always carry a spare, electric lamp bulb, as in these vehicles, current is derived direct from the magneto, and if the engine is raced the excess of current produced may cause the bulbs to burn out.

36.—The Care of Tyres.

Few people realize the importance of maintaining the correct air pressure in pneumatic tyres. The normal pressure for the Ford lies between 45 lb. and GO lb.. per sq. in. A rough-and-ready idea may be gained by kieking the tyres, when the foot should make no impression ; but this, of course, only proves that the tyre has enough air, and not that it has tci. much. It is advisable, in any case, to use a pressure gauge, such as the Schrader.

37.—Preventing Electrical Troubles.

• Under the bonnet, and fixed to the dash, is a connection block for the lighting, and a similar block the wires from which go to the commutator and coilbox. Make certain that all the screws on these blocks are properly tight; otherwise the circuits may be broken and bad lighting or bad running result, according to which circuits are affected.

Care should also be taken to tighten the. nuts at the back of the switch, the front of which can be removed by loosening the four screws.

38.—Why the Starter Pinion may Jam:

No series of hints on the Ford is complete without a reference to its starting. If the starter pinion jams, this may be due to one of several causes, or possibly a combination of two of them. (a) The starter motor spindle may be bent, but finding this may not point to the seat .of the trouble, for the bend may possibly be due to the jam ; (b) a freenent cause is advancing the ignition too far; (c) bad alignment of the transmission cover, which may be either packed too high or not high 'enough. The result of jamming is usually a burr (this has nothing to do with the French word pronounced in the same manner) on the ring gear. This burr must be carefully filed off, or, if too bad, a (new ring gear must be fitted. The rings are riveted into, position, and if a new ring be fitted the old rivets must be knocked out and the new ones inserted.

39.—Special Points to Lubricate.

Oilers are provided on the spindle bolts and shackles of the steering, and these should be attended to every week. .Also, every fortnight take off the hub caps of the front wheels and fill them with grease, and, while doing this adjust any side play by taking off the outer nut and setting the cones BO that each wheel will just balance. It must be remembered that the right-hand stub axle has a lefthand thread on the adjusting cone.

There are one or two more oilers on the ton truck than on the smaller type, particularly one on each of the brake-operating camshafts. These are important, as if neglected, the cam spindles may seize up and the brake be rendered ineffective.
