assembly, slip the side plate over the ends of

the pins then snap the clip into place in the

grooves on the ends of the pins using needle

nose pliers.

STEP 3: Move the chain above the spring

loaded motor chain tensioner . Photo 15B.

ALIGN THE MOTOR CHAIN

Correct motor chain alignment insures quiet

running and long chain life. The red adjust

plate surrounding the gearbox has 4 set screws

that allow it to be moved left or right and tilted

in any direction. The tilt is not normally need-

ed but is there to allow precision alignment.

STEP 1: Sight along the top of the chain to see

if it goes straight from the gearbox to the crank

set. Turn the cranks by hand to check that the

chain is straight. If it is, no adjustment is nec-

essary. If not, go to step 2.

STEP 2: Loosen the four bolts and nuts at the

corners of the adjust plate. The nuts for the

two bolts closest to the crank set can be ac-

cessed from the rear through holes in the

frame plates using a 10mm socket driver.

STEP 3: Turn the set screws next to each of

the four attach bolts to move the adjust plate

left or right. Turn each screw the same amount

to keep the adjust plate parallel to the EMD frame. If necessary the screws can be turned slight-

ly different amounts to adjust the tilt of the plate. Since the attach bolts are loose you will need

to press the motor/gearbox/adjust plate assembly against the frame by hand to check align-

ment.

STEP 4: Once you are satisfied with the alignment, tighten the four attach bolts and associated

nuts. Tighten each one a turn or two at a time so that the adjust plate settles evenly onto the

set screws.
