Used
Transmission Information
A
used transmission is just that, a used transmission. They
are just guaranteed to be a used Datsun Roadster
transmission, with no broken gear teeth, nothing more. We
consider them cores to rebuild, repair or use as is. If you
want a completely good transmission, rebuild one.
WHAT
WE DO: 1500/1600
Oil
pan is pulled off and a visual check is made for broken gear
teeth, broken forks or something else obviously wrong. It is
NORMAL for the reverse idler gear to look a bit beat up.
Transmission is shifted into each gear and hand turned to
check response. This only a simple inspection and check,
MANY things can not be apparent (bad bearing etc).
Countergear is wiggled to check for gross internal bearing
wear. Synchro's may or may not function properly, there's no
way to check them accurately without the transmission being
checked in an operable car. Sometimes we can tell if a one
or more synchros are COMPLETELY gone, but NOT ALWAYS.
Transmissions with obvious problems are set aside or sold
with a specific part number with their own specific
description, but if you want a trans with nice synchros, put
new synchros in! Oil pan is put back on, with the OLD
gasket, or remains thereof. You should ALWAYS order a gasket
and seal kit if you don't already have one.
WHAT
YOU SHOULD DO: 1500/1600
The
biggest problem with these is the bearings and shaft inside
the countergear gets worn then the counter gear can move
away from the mainshaft. At certain times only the tips of
the gear teeth are engaging, which leads to them shearing
away. ($$$$). ALWAYS yank the front cover and rear tailshaft
housing before intalling a transmission (like when you do a
clutch job) and check the shaft and bearings. Unless the
shaft is MINT (no visual change to surface) replace it and
the bearings. ALWAYS replace the countershaft bearings.
Servo boxes use caged needle bearings, Warner boxes use
individual needles. On the Servo boxes there are bearing
spacers inside each end of the counter gear. Don't lose them
as they are getting impossible to find. Normally your old
ones will be useable. Be sure to order the appropriate
gasket and seal kit.

Always
replace the rearmost countershaft bearing with the latest
production version of the bearing (#323-02, on 2000 TRANS
page hit link for BEARINGS AND BUSHINGS). Be sure to order
the appropriate gasket and seal kit as well.
