8N8872 Coupling Group
(1) Remove cover (1) and rubber blocks (2) from coupling assembly (3). Install coupling assembly (3) on the flywheel. Use an 8S2328 Dial Indicator Group to measure the TIR (total indicator runout) at four places 90° apart around machined surfaces (Z) and (Y) on coupling (3). Use a pry bar to move the crankshaft to the front of its travel before each reading is taken. Make a record of these readings. If the TIR is not over 0.13 mm (.005") the engine can be put in approximate alignment to the marine gear without connecting the shaft to the coupling at this time. If the TIR is more than this, use the steps that follow to get the engine in approximate alignment with the transmission. The final alignment reading must be made while the engine and marine transmission are rotated together without rubber blocks (2) installed. Use the indicator on surface (Y) to measure the total end play on the crankshaft. This reading will be needed later in the instruction. (2) Remove all dirt, rust and foreign material from the surfaces on transmission input flange (4), shaft assembly (5) and spacer group (6). Use a file to remove all burrs or damaged areas on the surfaces. Install spacer group (6) and shaft assembly (5) on flange (4) with bolts (7) and the nuts. arrows (8) on spacer (6) must be turned in the same direction, as shown. Loosely install bolts (7). Install bolt (9) through spacer (6) at (X) and tighten it. Tighten bolts (7). (3) Measure the length of inside part (10) and outside part (11) of coupling (3). Fasten part (10) to shaft (5) with two bolts. Put the crankshaft in the center of its end play. Put a straightedge across points (W) and measure from the straightedge to point (V). This dimension must be one-half the difference in the lengths of parts (10) and (11). This will put part (10) so dimension (U) is the same on each side. If needed, move the engine to the front or rear to get the same dimension at (U). (4) Install 6V2042 Alignment Yoke (12) and 6V2043 Alignment Bar (13) on shaft (5) with two 13.0 mmØ (.5") threaded rods and nuts. Install two dial indicators (14) and (15) as shown, one on surface (Y) and one on surface (Z). Use a pry bar to push the crankshaft to the front of its travel. Set the indicators to "0" in this position. Indicator (14) will show face alignment. Slowly turn shaft (5) by hand; do not use yoke (12) to turn the shaft. Make a record of the indicator readings 90° apart at (A), (B), (C) and (D). Face alignment as shown by the indicator must be as follows: a) A maximum TIR between (A) and (C) of 0.25 mm (.010") is permitted. The reading at (C) must be plus (+). This dimension is needed because, with application of engine torque to the propeller
