Operation Manual
Note:
New part clearances are as follows:
• Series 3000: 0.0030 in. (0.08 mm) - 0.0037
in. (0.09 mm)
• Series 3600/4200: 0.0040 in. (0.1 mm) -
0.0047 in. (0.12 mm)
6. Repeat for the remaining assemblies.
Crosshead and Connecting Rod
Assembly
Removal
1. Remove the crankshaft from the pump as
.
2. Use two people to lift the crosshead/con-
necting rod assemblies from the crank-
case. The weight and location of the as-
semblies make it difficult for one person
to remove on their own.
Disassembly
1. Remove the two set screws from the
crosshead (Figure 167). The set screws
are installed on top of one another in the
same hole.
2. Slide the pin out from the assembly (Fig-
ure 168).
3. Remove the connecting rod from the cross-
head.
4. Keep the components for each assembly
together.
5. Disassemble the remaining assemblies.
Bushing Inspection
1. Use a micrometer to measure the outer
diameter of the pin in three places and
record the measurements.
2. Add the three measurements and divide
by 3 to get the average diameter.
3. Use an inside micrometer to measure the
bushing in the connecting rod in three
places and record the measurements.
4. Add the three measurements and divide
by 3 to get the average diameter.
5. Subtract the diameter of the pin from
the inside diameter of the bushing. If the
remainder is greater than 0.008 in. (0.2
mm), the bushing must be replaced. Note
the new bushing will require honing after
installation into the connecting rod to
achieve the clearance listed below.
