ASSEMBLY

(Refer to Figure 3-47).

Apply a coat of lubricating oil to the large outside diameter of the idler shaft (26).

b. Install the large outside diameter of the shaft (26), from the gear pocket side of the body (31), into the

bore in the pump body.

Use gear and spacer mandrel and an arbor press to push the shaft (26) into the bore.

d. Apply a coat of lubricating oil to the inside diameter of the driven gear (27). Install the gear (27) onto

the drive shaft (30). Use an arbor press to push the gear (27) onto the shaft (30). S e Table 3-6 and

Figure

3-51 to find the correct amount of protrusion the drive shaft must have after the gear is

(31). Apply a coat of lubricating oil to the inside diameter of the drive gear(s) (34). Put the gear (34)

on the

shaft (30) on the side of the body opposite to the gear pockets; use an arbor press to push the
