Installation

PERFORMANCE ORDER
1. Installation is made in the sequence, the return to removal taking into account the next moments:

– install a new sealing ring on the step engine and apply on it a thin film of lubricant for simplification of installation of the step engine;
– for an exception of damage of the case of a throttle or a tip of a plunger of the step engine which acts more than on 28 mm from the interfaced surface of the step engine, being careful, press a plunger inside against the stop. After start of the engine the step engine needs to be installed in a starting position, using signals from the ECU block;
– before a vvinchivaniye of screws of fastening of the step engine apply the means interfering their unscrewing on a carving of screws.
