Chev V8 168T late to Landcruiser 4.2L 4-speed auto
Toyota Landcruiser engine conversion using Chev V8 late (post 1986) - 168T
- 4.2L 1HDT 4-speed auto
Bell Housing Adaptor Kit
The flywheel housing is supplied which measures 61 mm/2.4" long. This housing has the GM bolt pattern on the front and the Toyota 1HDT, bolt pattern on the rear.
The transmission torque converter is coupled to the flywheel via a crankshaft adaptor. The adaptor has a special bolt pattern and spigot diameter on the transmission end with the GM crankshaft bolt pattern and spigot diameter on the engine end. This allows the new flex plate (supplied in the kit) and the Toyota torque converter to be bolted to the rear as with the old 1HDT engine.
On the front of the crankshaft adaptor a manual flywheel is used instead of a flex plate, as there is no provision to support a flex plate when the starter motor is engaged.
When ordering a Chev kit you must make sure that the GM starter motor you intend using is the correct type. Chev V8 engines were released with two flywheel and flex plate sizes; they where fitted with a 153-tooth ring gear or 168-tooth ring gear, as a result two starter motor offsets are available.
The kit will only suit the 168-tooth ring gear.
It will also be necessary to identify the year of the engine, after 1986 the engine crankshaft bolt pattern changed. The bolt pattern is smaller as is the spigot, which locates the flywheel on the crankshaft (52.4-mm). The post 1986 Chevy small block engines are also externally balanced. One way to identify a late model Chevy engine is by the one-piece external, rear main oil seal.
NOTE 1: This kit will only suit the late (post 1986) Chev V8 with a 168-tooth ring gear.
NOTE 2: The factory automatic transmission will require a stand-alone computer to control shifting of the transmission once the original engine and ECU is removed.
NOTE 3: You will need to reuse the original 168T GM manual flywheel from your engine.
