[QUOTE="divemaster5734, post: 138581, member: 1320"] Thank you for the diagram. I don't have a ball bearing (#22) between the 2 push rods(assy #18-21 and #23) . I have the placement sequence, but there looks to be around 3/16" between the driven gear(#4) and the kick gear when assembled. I didn't take a picture when I started, dumb move. After setting the kick assy the #4 didn't want to seat. I had to slide the kicker on and turn the crank to move the oil pump drive gear and kick idle gear to mesh with #4 to get the last 1/2". The thrust washer(#5) sits on the crank between #4 and #6. The crank has a spline for about 3/4", then a short no spline, then a spline section. 1st spline section is where the the friction plates ride, 2nd section is where the clutch housing with the driven gear rides. The thrust washer has internal spline groves. When the #4 is seated there is no room for the washer to sit on any spline section. I'm just not sure if that's normal. [/QUOTE]
