E2)
Install the motor plate support bracket (1130)
using two 4-40 X 1/4” flat head screws
(6021). The screws come up from
underneath the chassis and thread into the
support. Make these two bolts just finger
tight for now. Notice the support is off-set to
the left.
BULKHEAD
E3)
NOTE: Tolerances are tight where the chassis mates with the bulkhead. Much
stress is transmitted through these parts and a tight fit adds strength. Most
bulkheads are OK, but some come out of the mold slightly oversized in one small
spot. Test fit your bulkhead to ensure it fits snugly and properly into the chassis,
pressing it down and forward so the transmission bolt holes like up with the holes
in the chassis. (left photo) If you have a bulkhead that does not fit all the way
forward, or that pops back when you let go, lightly file the rear inside corners of
the chassis “box” to ensure proper fit. In the right photo, the long arrow shows
where the chassis was filed, the short arrow shows the file contacting the
chassis.
