Tsurumi’s Operation, Service, and Repair Manual

NOTE:

•

Refer to View D for an illustration depicting the mating ring. Lubricate mating ring and cushion
with water. Make the measurements that need to be taken for calculating the thickness of shaft-
mounted shims. 

I.

Measure and record dimensions A and B. Subtract dimension B from dimension A. The

resultant dimension is the shim thickness required to provide the required clearance
between the rotating and fixed seal elements.

J. 

Select the combination of shims (41) that will provide clearance of 0.020 inch to 0.040 inch
(0.508 mm to 1.016 mm).

K. 

If the liner (5) was damaged, remove two screws (25) and separate casing cover (2) from
inner casing (4). 

L. 

Remove three screws from liner (5) and inner casing (4). Separate liner (5) from inner
casing (4) 

M. 

Secure liner (5) to inner casing (4) using three screws (25).

View E: 

Install seal in

pump casing (refer to
Figure 4-5) with seal
driving tool driver.
Replace O-Rings if
damaged.

View D: 

Use water as a

lubricant on mating ring
and cushion. Put side of
mating ring with white
mark facing downward.
