Bell Housing Adaptor Kit to Suit Chev V8 (early) 168T to LandCruiser 4.2L 5-speed manual
The flywheel housing is supplied which measures 61mm/2.4″ long. This housing has the GM bolt pattern on the front and the Toyota 1HZ, bolt pattern on the rear.
The new flywheel supplied in the kit accepts the original Toyota 11″ clutch. The flywheel is offset to the rear to place the clutch in its original position. The flywheel has no ring gear and must be used with the original GM flex plate and ring gear. Spacers and bolts are supplied to fix the flexplate to the flex-plate stiffener.
When ordering a Chevy kit you must make sure that the GM starter motor you intend to use is the correct type. Chevy V8 engines were released with two flywheel and flexplate sizes; they were 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.
