Installing timing gears and keys
1.
Insert the timing keys into the timing key slots in each of the drive shafts, Figure 1.
2.
Mesh the timing gears together such that either the factory timing marks or your scribe marks are aligned
before installation onto the shafts, Figure 2.
3.
Slide the timing gears onto the shafts as a pair, Figure 3. If needed, slightly rotate the shafts to assist in gear
installation. DO NOT force the gears down the shaft or hammer them into place - they should slide smoothly
onto the shafts until they contact the bearing plate, Figure 4.
CAUTION
PROPER TIMING AND ALIGNMENT OF THE GEARS AND LOBES IS
CRITICAL. Failure to properly time the pump assembly will cause immediate
failure of the pumping mechanism.
