UPGRADE KIT FOR ALPHA LUBRICATOR
Basically Alpha system has lubricating algorithm with load proportional control above 25% engine load and switch to rpm proportional control below 25% engine load, however there issued the over-lubricating at low load operation on MAN service letter, SL2011-544 as alpha system has a limit of revolution per injection and this reached to max. value prior to 25% engine load as illustrated Fig.1.
In this case, rpm proportional control is adopted at 35~40% engine load and causes the excessive lubricating at very low load, e.g. 10% engine load.

ADVANCED MEASUTAL

Introduction
Measutal® is a powerful and precise digital crankshaft deflection gauge.
It is fitted between the crank webs, the engineer takes all readings from outside the engine through wireless communication, without the drawbacks of heat, oil drop, etc.
The instrument consists of a measuring unit and a display unit. The display unit displays the deflection data and transfers data to Computer.

GEISLINGER T/V DAMPER 5 YEARS MAINTENANCE
& GMS RETROFIT
However “small service” should be carried out 20 ~ 24,000hr, it is very difficult to do so for ship’s crew even open-up for shield cover.
Therefore every 5Y(Dry-dock), we recommend to carry out bellow works by HSD Engine or authorized engineer
*Also can be done as combination with ME maintenance during dry-dock.

DAY 1. Preparation
