FOR MODELS: JGW, JGR AND JGJ SECTION 4 - LUBRICATION AND VENTING

PAGE 4 - 16 1/01

Lubricant flow shifts piston 1 from right to left dispensing piston lube through connecting

passages to outlet 1. Piston 1 shift directs flow against right side of piston 2. (See Figure 4-

5: illustration 2)

Lubricant flow shifts piston 2 from right to left dispensing lube through valve ports of piston 1

and through outlet 2. Piston 2 shift directs lubricant flow against right side of piston 3. (See

Figure 4-5: illustration 3)

Lubricant flow shifts piston 3 from right to left dispensing lube through valve ports of piston 2

and through outlet 3. Piston 3 shift directs lubricant through connecting passage to the left

side of piston 1. (See Figure 4-5: illustration 4)

Lubricant flow against left side of piston 1 begins the second half-cycle which shifts pistons

from left to right dispensing lubricant through outlets 4, 5 and 6 of the divider valve.

If pistons refuse to move, check for air lock in one or more valve ports by manually shifting a

piston from right to left.
