1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully counterclockwise (viewed from the drive side).
Temporary tightening torque: 1 - 1.5 N.m (0.1 - 0.15 kgf.m)
2. Move the actuator in the clockwise direction when viewed from the drive side, and adjust so that it becomes the adjustment point of the adjustment value. Then tighten it.
Tightening torque: 7^9 N.m (0.7^0.9 kgf.m)
3. After prestroke actuator installation adjustment, simultaneously stamp both the actuator side and housing side.

INFORMATION RELEASE MEMO
Reman
PELJ1163 ?2010 Caterpillar CAT REMAN ANNOUNCES AN APPEARANCE CHANGE TO MECHANICAL UNIT INJECTORS FOR 3600 ENGINES
Announcement
In the past, Reman 3600 mechanical unit injectors consistently had only one drill hole in the body. Effective immediately, dealers will now see some bodies with one drill hole and some bodies with two drill holes. Validation tests confirm the number of drill holes will not impact quality, reliability, durability, fit, or performance. Affected part numbers are listed in the table below.
* For serial number specific information please see SISWEB.
Effective immediately, Figure 1 and Figure 2 will both represent acceptable 3600 mechanical unit injector appearances.
Features and Benefits
Cat? Reman Fuel Injectors offer excellent value to customers. Customers who want fast repair turn-around, superior quality and reliability, and lower repair costs will benefit from the use of these remanufactured fuel transfer pumps. Cat Reman Fuel Injectors provide immediate, off-the-shelf availability at a fraction of the new price.
Features Benefits
All critical engineering changes and updates included Improved reliability and performance
Worldwide availability through Cat parts distribution system Customer access regardless of location
Backed by Caterpillar parts warranty Consistent support
Core Acceptance
Core Acceptance Criteria for Caterpillar Remanufactured Mechanical Unit Injectors is simple, visual, and requires no special tools. Consult the Unit Injectors ? Mechanical Core Acceptance Criteria SELD0030 for complete details.
Warranty
Please consult the appropriate Cat parts warranty statement for your area.
Core Management
Please refer to the Cat Core Management Information System (CMIS 2) Parts Information application describing all Cat Reman part/CAF and related information.
