Land Cruiser manual - Advance Adapters

August 1980 to 1989: In August of 1980, major drivetrain changes occurred in both the FJ40 and FJ60 models. The
transfer case design was changed to a split-case configuration with a 19 tooth internal spline on the input gear. The low gear ratio
was 2.27:1 in these transfer cases. There are three different models of this transfer case; however, the differences are very minor.
The transfer case adapters we offer will work with all three models. See Page 27 for low gear options for this transfer case.
When using one of our transfer case adapters, our output/spud shaft is exactly the same length as your original output shaft. The
gears and spacer will all be reused, but the old rear nut and washer will need to be replaced (items provided in kits). The photos
below show the proper assembly.
REPLACING THE STOCK 4 or 5 SPEED MANUAL TRANSMISSION: The crossmember is located under the transmission.
When installing a different transmission, this mount may need to be relocated or replaced. This depends on the transfer case
adapter. Some of our adapters have provisions to retain the stock mount while others require a custom one to be fabricated.
REPLACING THE STOCK AUTOMATIC TRANSMISSION: The stock crossmember was bolted under the stock adapter
housing. None of our adapters have the provisions to use this crossmember without modifications. We have not seen a great
deal of these transmissions being replaced and, therefore, cannot offer much assistance in this area.
NOTE: Our rear transfer case support, P/N 716022, will not work on a 19 spline split transfer case.
1990 to 2002: In 1990, a new transfer case model was introduced, the HF2A. This transfer case is a full time 4WD unit. We
import a few transmission adapter housings from Mark’s 4WD Adaptors that retain this transfer case. Most applications do not
require driveshaft modifications, nor do they require crossmember modifications. The adapters we carry for this transfer case are
designed around replacing the A442F automatic transmission only.
TRANSFER CASE CONSIDERATIONS:
Optional transfer case equipment such as overdrives (Fairy Overdrive) and/or P.T.O. winches WILL NOT be compatible with any of
our transfer case kits. The one exception to this would be the P.T.O. winch that bolts on the driver's side of the transfer case.
SEALED BEARING (Early 10 spline & 16 spline transfer cases only): Most of the adapters on the Transfer Case Selection
Chart come with a new 307 sealed bearing. On some of the manual transmission adapters, this bearing is not provided because
the two gear boxes use the same type of lubrication. If you would rather isolate your gear box fluids, a sealed bearing can be purchased
under P/N 716301.
BOLTS FOR TRANSFER CASES: The stock Land Cruiser transfer case bolts are metric. Most of the transfer case adapter housings
we manufacture are drilled and tapped for 7/16”-14 fasteners. These bolts are a little smaller in diameter than the stock metric bolts;
however this will not cause any problems when fastening the units together. We also produce a few adapter housings that retain
the stock metric fasteners.
