As a second check, the marked tooth (58) on camshaft beveled gear (59) should point down toward the crank- shaft. CAUTION Do not force shouldered shaft. The shaft is machined with a 24--tooth spline on inner end, and a 28--tooth spline on outer end. The difference in number of teeth provides a vernier effect which makes it possible to index the shouldered shaft so it will engage the splines of the inner bevel gear shaft and the outer bevel gear shaft at some point within 360 degrees. An accurate setting is then provided without changing the relationship of the camshaft and the crankshaft. 21. Maintain the position of camshaft assembly (30) and insert shouldered shaft (9), using mechanical puller (7), and mate splines on lower and upper bevel gear shaft (6). When splines of shouldered shaft (9) do not mate with low- er and upper bevel gear shaft (6), withdraw shouldered shaft (9) and turn slightly before again attempting inser- tion. NOTE It may be necessary to repeat this operation a number of times before splines will mate and allow shouldered shaft to be inserted into position. Figure 10 6 7 9 30 58 59
