Joints seemingly as tight as a mechanic can get them allow dirt to pass through. : The reason for the i dirt being so undesirable near work- , tng parts of the chassis Is not so much because it doesn't look well but be- t cause It eventually gets to a moving surface and starts rapid wear. : Around the engine and other parts ef the car there are supposedly tight j Joints In addition to actual openings. , Take the front end cover, cbmmonly called the timing gear case cover. Vibration Vi-bration may loosen a few of the hold-... hold-... lag outs, allowing the cover to move away from the crank case a small fraction of an Inch. With an accumu- : latlon of dirt over the cover some of the dirt is bound to get to the gear teeth. Dirt and lack of lubrication of front end gears are responsible for rapid wear and noisy operation. Every owner ought to keep the engine en-gine clean by an occasional kerosene bath. Spray kerosene all over the en- f glne and wipe off every bit of dirt yon can. This goes for the crank cose as . well as the parts that you can see wben you lift the hood. Dirty oil, oil '1 with sediment, old oil not changid for some time are all causes of rapid engine en-gine wear. How many owners ever see to It that the combination breather and oil filler is clean on the Inside? - In some designs there Is every chance for a quantity of dirt to settle on the Inside, In-side, and that Is washed down into the crank case when the next oil filling Is made. A dirty engine means a loss In efficiency ef-ficiency and a premature trip to the , repair shop, where the cost of parts replacements will be higher than expected. ex-pected. The timers are usually covered cov-ered with mud and dirt, and this gets Inside, cuts the segments. Interferes with proper Ignition, and brings about the need for a new timer In a few months. Look Inside of a timer that Is generally dirty on the outside and one will find dirt also. Generators and starting motors on the average car do not get very much attention of any kind by the owner, but they deserve a good cleaning. Some starting motors are not fully Inclosed, while others, even when covered, seem to accumulate accumu-late dirt. I would suggest to the owner that, when he haa a few hours to spare during dur-ing any month, he give the engine a thorough cleaning, removing dirt from all Joints, from oil holes, and the like. The underneath parts of the car are admittedly hard to get at, but that should not be aft excuse for total neglect. neg-lect. Underneath the car there may be many places that require oil through small cups, oil holes, etc. While some manufacturers are so far behind as to continue to use oil holes In exposed places, the owner of a car using them shoi-ld not let them became filled with dirt If I owned a car w ith exposed oil holes on cross shafts and other parts I would have a mechanic Install automatic auto-matic feed oil cups. Universal joints at best are hard to lubricate, and even If covered with a leather boot are not proof against the ravages of dirt and mud The more dirt that you allow to accumulate around these parts the more dirt will get to the working surfaces. |
