COMPRESSOR DRIVE BELT MAINTENANCE... There are several factors that have major effects on compressor drive belt life expectancy and reliability. Belt alignment and proper tension are the two most critical and controllable by the installer and end user. When improperly installed or maintained drive belts can cause significant damage to the compressor and clutch and other components as well as pose a safety issue.
Ounce of Prevention...
Never use compressed "shop" air to leak or pressure test an A/C System. Under certain conditions, pressurized mixtures of R134a and air are combustible. In addition shop air will inject excess moisture into the system.
I think R134a when compressed with Air has some sort of reaction which is what drives high side pressures up when system is not vacuumed out.
Seems to only happen with pressure though, e.g Air+R134a can Co-exist without a problem but when pressurized from what I heard causes some sort of reaction.
Is there any more information to this?
