If gasket is not notched, apply gasket sealer around end of rod (outside block) to seal when
bearing plate and gaskets are installed.
5. Crankshaft Installation
a. Place block on base of arbor press and carefully insert tapered end of crankshaft through inner
race of antifriction bearing.
b. Turn crankshaft and camshaft until timing mark on shoulder of crankshaft lines up with mark
(dot) on cam gear as shown in Figure 37.
c.
When marks are aligned, press crankshaft into bearing -- make sure gears mesh as shaft is
pressed into bearing. After shoulder bottoms against inner race, recheck timing mark to make
sure they are still aligned.
d. Crankshaft end play is controlled by the thickness of gaskets used between the bearing plate and
block. End play must be checked after bearing plate is installed -- directions stated in Step 6.

6. Bearing Plate
a.
Press front main bearing (shielded side up) into bearing plate. Make sure bearing is straight and
true in bore and bottomed properly. If cocked, crankshaft end play will be adversely affected.
b. Crankshaft end play is determined by thickness of gaskets used between block and bearing plate.
Initial use of one .020" and one .010" gasket should bring end play within limits -- this must be
checked after bearing plate is installed.
c. Install gaskets with thicker gasket next to block, place bearing plate on crankshaft and carefully
press plate onto shaft and into position on block. Install cap screws with copper washers and
secure bearing, plate to block. Draw screws up evenly to avoid distortion of bearing plate.
d. Crankshaft end play is measured (with feeler gauge) between inner race of rear bearing (P.T.O.
end) and. shoulder on crankshaft. If end play is not within tolerance as stated in Clearance
Section, remove bearing plate and add or subtract gaskets to achieve proper clearance.
