Planetary gears in the 4+3 overdrive are not like automatic transmission
planetary assemblies. Because of this difference, we recommend that you
understand this concept. Normal planetary gear systems have a sun or center
gear, 4 planet gears, and an outer ring gear. Since the 4+3 has no ring
gear but rather 2 stage planets each planet must be timed with one another
so the stages remain in phase. There are timing marks on the second stage
( punch marks actually ). Line the marks up as shown in the picture. Then
place the sun gear in the planetary.
sun gear drops in... your in time. If it doesn't drop in, notice which
of the 4 gears moves or gives you the most resistance and reposition it.
After the gears are in time or thought to be in time, place the carrier
section on. It should drop right on. Do not force the carrier
on! If the carrier doesn't drop on you are still out of time
and must reposition the gears. This can be a time consuming task.
