63 – Condensation of Water in Oil Tanks
With cold weather approaching it is advisable for all owners of 1933, 1934 and early 1935 Dry Sump machines to take precautions against collection of excess condensation of water in the oil tank. The oil feed line nipples in the oil tanks of the above models were so made that one half inch of water could collect in the bottom of the oil tank. This collection of water has been found to be injurious. Oil to the feed line should be drawn from the bottom of the oil tank, or as near as the bottom as possible.
To correct this condition on the 1933 and 1934 45 cubic inch models, cut off the top of the oil tank outlet body or feed nipple to the top of the thread. Remove and discard screen, if necessary. On the 1934 74 cubic inch models, cut off the top of the oil tank outlet body or feed nipple to the top of the thread. The supports for the breather tube in this assembly may be resoldered in the lower position. On early 1935 45 and 74 cubic inch models, cut off the short tube extension in the feed line nipple which screws into the oil tank.
If you will change these nipples in the tanks on any machines that you have, this trouble will be eliminated. Any condensation of water will be burnt out as fast as it gathers, rather than collecting in the bottom of the tank, as it has in the past.
At the same time be sure you are be sure you are using the specified grades of oil. For operation above freezing – SAE50; for operation below freezing – SAE20W.
These grades are now carried in all warehouses.
