This car was with us in July last for engine repairs after 40,412 miles. The condition of the engine was reported at that time on Owner's Complaint Report No. W.26, a copy of which we attach. It may be remembered that the engine was dismantled primarily to drill extra lubrication holes in the crankshaft, but the main bearings were not renewed as it was possible to obtain some further life out of them by stepping the liners to take up slack. This was the third time this had been done and it was mentioned that the bearings would not stand taking up again, and that new ones would be necessary next time. The car is with us again after having run a further 4,200 miles in six weeks, making a total of 44,629. The roughness in the engine has re-appeared due to further hammering of the main bearings. As it was not considered practicable to take up the main bearings again, the engine has been removed from the frame in order to fit new bearings. We give on the following page, particulars of the amount of wear of the crankshaft and of the total hammering of the main bearings since new. Naturally, the total hammering of the bearings does not represent the actual amount of slack at the present time, as this has been taken up on three previous occasions. -continued- | ||
