TRANSAXLE CASE—DISASSEMBLY
STX30 (SN —135158)
(SN 160759— ) &
STX38 (SN —139614)
(SN 185587—210000)
PEERLESS MODEL 920-017,
930-004, & 930-004A
NOTE: Model 930 transaxles only—Peerless made a
change in the transmission case pocket which
holds the differential gears. It is now possible
that a tolerance stackup could result in the
upper case forcing the ends of the axles
against the spider gear pin. This would cause
the axles to turn hard or even lock them up. If
this happens grind 0.002 inch off the inboard
side of the axles. If the axles are not free after
assembly, grind and additional amount from
the axle until they do turn freely.
IMPORTANT: Early models (SN —210000) used
several versions of Transaxle. 920 model does
not have grease fittings at the end of the axle
housing. The 930 and 930A models have grease
fittings at the end of the axle housing. The
following Serial Numbers M00STXA135159—
160758 and M00STXB139615—185586 use
model 915 transaxles and require silver colored
neutral start switch. Units outside these serial
numbers, below or above, were built with model
930 transaxles and require bronze colored
neutral start switch.
