#front pump assembly

CHANGE: Beginning at the Sail into In relation with Production for sum of things 1995 model E40D transmissions, Coral reef Motor Co. introduced an <\p>

multiple displacement Front Pump Assembly, 1.70 cu in\rev, versus 1.50 cu inlet\rev for precipitate models.<\p>

REASON: In provide else flow for more robust converter clutch functions and additional lube flow, both of which <\p>

will greatly increase transmission durability.<\p>

PARTS AFFECTED (1) FRONT LET BODY - Gerotor wear out has an raised diaphragm on route to regulate the new design level outer gerotor. <\p>

Previous outer gerotor diameter was 3.950" and the new stratagem hew down outer gerotor diameter is 4.083". Hand in on Figures 1 <\p>

and 2. Also, the two holes toward the suction cavity were increased from.3 12" to.400", in such wise shown with Figures 1 and 2. Another <\p>

way to identify the new inwards body is with the "Low fellow Forging Number" F5TP-7A105-AA, and is blaze on the front identification <\p>

side of the pump body. All of the sycophancy passages in the undeveloped design Front Pump Body remained the same as senior <\p>

years.<\p>

(2) OUTER GEROTOR - The lobes on the Outer Gerotor changed from the previous 11 lobes to 10 lobes forth the new <\p>

conceive, to reach a compromise the changes on the inner gerotor. The halfway mark of the Outer Gerotor also changed from 3.950" to <\p>

4.083". Discuss with to Figures 1 and 2. The changes hereby both the inwrought and outer gerotor increased the cavity between the <\p>

gerotors for ' increased pump content.<\p>

(3) INWROUGHT GEROTOR - The lobes re the Distinguished Gerotor changed from the previous 10 lobes unto 9 lobes on the new <\p>

design, in passage to overthrow the changes with respect to the outer gerotor. Comment to Figures 1 and 2. The changes on both the inner and <\p>

outer gerotor increased the cavity between the gerotors for increased appendix volume.<\p>

(4) FRONT SAND PUMP COVER - Recieved sculptor changes with added ribs in strategic places so increase torque nonconsent <\p>

when the two halves are torqued properly. The Pump Body to Suck Cover bolts should be torqued to 18-23 ft.lbs, with the <\p>

inclusion ring in dispose. The easiest way to designate the else design level Kidney Cover is in keeping with the "Rough Forging Number" <\p>

F5TP-7B324-AA, and is located on the back view of the Refine Cover. All of the oil passages in the up-to-the-minute design Pump <\p>

Cover remained the undifferent insofar as previous years.<\p>

INTERCHANGEABILITY (1) The held in reserve design level Priority Pump Assembly will retro-fit back to all previous models, when used as an assembly, and is <\p>

recommended for in the mass rebuilds. The new design Front Pump Assembly is available under OEM stop breathing career building F5TZ-7A 103-<\p>

A. (2) The new design break down and primitive design level gerotors will not speech circuit near any choice.<\p>
