Engine News SEBD9547, 7 July 2008, "New Starter Lines Group and Prelube Pump Group are Used". Disregard the original article. The effectivity is changed. Refer to the information below.Description of Change: The new lines groups are acceptable for use on the above engines that are in petroleum applications. These lines groups meet the petroleum industry standards. The new pump is more rugged and the duration of prelubrication is reduced.Adaptable To: For the new lines groups, the connection point is a three inch American National Standards Institute (ANSI) flange. This flange is located 48 inches in front of the flywheel on the in-line engines. This flange is located 60 inches in front of the flywheel on the vee engines.

Typical lines group for vee enginesThe 326-2623 Prelubrication Oil Pump Group incorporates the 322-2734 Prelubrication Motor. The new pump group uses the existing 324-9181 Gear Pump Group and the 9Y-3297 Bracket As . The 322-2734 Prelubrication Motor operates in the same pressure range as the currently used starting motors.The 7W-0522 Air Motor Lubricator Gp, the 4W-2100 Pressure Reducing Valve, the 165-7805 Air Relief Valve, and the 302-2199 Relay Valve are no longer required in the prelube system.The 322-2734 Prelubrication Motor can be adapted to the 1W-4776 Prelubrication Oil Pump Group. This change will replace 3N-1287 Prelubrication Motor that is currently used. The new 322-2734 Prelubrication Motor is approximately 140 mm (5.50 inches) longer than the 3N-1287 Prelubrication Motor .324-9535 Prelubrication Oil Pump Group Specifications Free air consumption with 1034 kPa (150 psi) supply pressure ... 6 cubic feet per second Oil flow rate at 170 kPa (24.7 psi) oil pressure ... 20 gallons per minute The lines groups for each engine arrangement are listed in Table 1 and Table 2.
