NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop
Products Guide" for tools and supplies suitable to collect and contain
fluids on Caterpillar products.

1. Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned
in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry
parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts and
clean all parts. If any parts are worn or damaged, use new Caterpillar parts for replacement.
2. Lubricate seals with clean transmission oil.

Measure the clearance with a dial indicator.
3. Temporarily install the stator in the turbine. Check the clearance between the turbine and
the stator. Install Tooling (D) on the turbine wheel, as shown. Move the stator toward the
dial indicator until the outside diameter of the stator is against the inside diameter of the
turbine wheel. Move the dial indicator against the stator. Put the dial indicator on zero. Push
the stator away from the dial indicator until the stator outside diameter is in contact with the
opposite inside diameter of the turbine wheel. Measure the clearance. Make this
measurement at four points around the turbine wheel. The average of this measurement is
the difference between dimension (N) and dimension (M). When new parts are used, the
difference between dimension (N) and dimension (M) must be from 0.71 mm (0.028 inch)
to 0.91 mm (0.036 inch). The maximum permissible clearance with worn parts is 1.37 mm
(0.054 inch).

4. Temporarily install the stator in the impeller. Use the same procedure that was outlined in
Step 42 in order to check the clearance between the impeller and the stator. When new parts
are used, the difference between dimension (P) and dimension (Q) must be 0.71 mm (0.028
inch) to 0.91 mm (0.036 inch). The maximum permissible clearance with worn parts is 1.37
mm (0.054 inch).
5. Use a suitable measuring device to measure the outer diameter of the stator at location (S).
Use a suitable measuring device to measure the inner diameter of the ring at location (R).
When new parts are used the difference between dimension (R) and dimension (S) must be
3/22

0.56 mm (0.022 inch) to 0.71 mm (0.028 inch). The maximum permissible clearance with
worn parts is 1.07 mm (0.042 inch).
6. If bearing race (67) has been removed, install the race now. Lower the temperature of the
bearing race. Install the race in housing (13) until the race contacts the shoulder that is in the
bearing bore.
7. Install seal (67) to piston (65) .
