AN interesting appliance for expediting engine reconditioning i being shown to the trade for the first
time at this year's Motor Show at Olympia. Marketed by Harvey Frost and Co., Ltd., 148-150, Great Portland Street, London, W.1, the Rh` crankshaft assembly jig enables the operator to true crank pins and journals, test crankshafts for whip and balance, fit big-end and connectingrod bearings, piston rings and pistons, and test the alignment of connecting rods. All these tasks can be carried out with the new appliance, which is bolted to the workshop bench.
The jig takes crankshafts of from one to eight-cylinder • size and from in. to 3 ins, in diameter, and with or without the flywheel. The crankshaft is set between centres when testing for whip and balance, thus eliminating the need for a lathe. It is interesting to note that the alignment of connecting rods is carried out on the actual crankshaft and not on a separate jig. The tool is certainly a time and labour saver.
In addition to this new appliance Harvey Frost and Co,, Ltd., informs us that in co-operation with WorthingtonSimpson, Ltd., it has entirely re-designed its 'ELF Hydroforee vehicle washer, which, in its new form, also makes its appearance at the Show.
The improvements which have been incorporated enable the plant, by means of a 2 h.p. electric motor, .to deliver six imperial gallons per minute at a pressure of 325 lb. per square inch. It is claimed that this performance gives a volumetric efficiency of 98 per cent.
Texrope is used for transmission and the gland packings tire of an entirely new design and are foolproof.
The plant is fitted with nickel-treated steel plungers, impregnated with chromium, thereby obtaining the maximum durability and the minimum friction. The valves are of a simple type and are made from specially treated steel so as to avoid corrosion. An oil bath and dippers'are used to ensure an automatic supply of oil to all essential parts.
The assembly of the parts has been so arranged as to
make every working component easily accessible. The plant is compact and is supplied complete with a east-iron base.
