Pada torak-torak selalu terjadi kebocoran gas selama langkah kompresi dan usaha. Gas bekas itu masuk karter dan harus dibuang. Pada motor lama, gas tersebut. dibuang keudara luar melali sebuah pipa, akibatnya timbul polusi. Pada motor modern, gas yang masuk karter dialirkan kembali kesaluran masuk melalui sistem ventilasi karter
Removal Instructions :
- Disconnect the negative (ground) cable from the battery.
- Compress and turn the horn button 1/4 turn counterclockwise to release the button from the retainer.
- Disconnect the horn wire at the horn blowing switch.
- Remove the three (3) screws and insulators attaching the horn ring and horn blowing switch to the
steering column. Remove the horn ring and switch.
- Loosen the steering wheel nut several turns and install the steering wheel puller tool and remove the steering wheel nut and steering wheel.
a. Dirt in the Lubricating System
The presence of dirt particles entrained in the lubrication system is one of the most frequent causes of bearing damage. The root of the problem is usually that the engine is not sufficiently clean. In line with the nature and size of the foreign
particles, the bearing will exhibit a correspondingly lesser or greater degree of circumferential scratching and, usually, any debris that may have become embedded in the lining.
Recommendation : when repairing the engine, ensure that the entire lubrication system is carefully cleaned
b. Dirt on bearing back
The presence of a foreign particle trapped between the bearing back and its housing will lead to a raised area, with the ensuing risk of contact between this protruding high-spot and the journal. Signs of this will be seen in the area opposite
the particle, along the inner surface of the bearing, where there will be evidence of marked localized wear. Recommendation : ensure that all housings in which bearings are to be seated, are carefully cleaned prior to assembly.

In addition to keeping the water and coolant level where it needs to be, you can prevent trouble by keeping an eye out for leaks and replacing old or damaged hoses. Figure bellow shows the common trouble spots in the cooling system the places where you should check for coolant leaks.
Wear gloves when connecting or disconnecting service gauge hoses.
Always wear eye protection when working around refrigerant and air conditioning systems. Since the system’s high side is under high pressure, severe injury to the eyes could result if a hose were to burst. Refrigerant also evaporates rapidly when exposed to the atmosphere, causing it to freeze anything it contact. That’s why it’s a good idea to protect skin and clothing with a shop coat. And a bad idea to wear loose clothing or things like ties or jewelry that could get caught in the drive belts.
Never strike a section of copper or aluminum tubing or a heat exchanger in a charged refrigeration system. A blow from a heavy tool could easily cause the relatively soft material to rupture.
If you have to apply force to a pressurized refrigerant threaded fitting, always use a back-up wrench to avoid the direct transfer of excessive torque to a section of refrigerant tubing. Whenever possible, use wrenches specially designed for "1/4 inch flare nut" fittings (R-12 systems) or for 112-inch "Acme" fittings (R-134a systems).
Some overheating problems aren’t related to the cooling system at all. Other circumstances that can cause a vehicle to overheat include lack of oil, a blown head gasket, and transmission problems. If the cooling system seems to be in good order after you check it and do the maintenance work in this chapter, investigate these possibilities :
- Late timing : If you haven’t tuned and timed your engine recently, late timing may be causing it to overheat by making the spark plugs fire the fuel/air mixture after the piston moves back down from the top of its stroke. When the spark plugs fire too late to allow all the gases to burn properly, more heat burdens your cooling system. Late timing alone doesn’t cause a car to overheat by more than a few degrees, but coupled with other problems, it can bring the engine temperature to a critical point. The remedy is simple: Just check your timing and adjust it.
