Notes:
This kit is designed to adapt the Atlas transfer case to a Toyota FJ Cruiser transmission. This adapter plate works
with the 6 speed manual transmission only. The exhaust that runs under the stock transfer case can remain installed when
doing the new transfer case install; however, we found it was much easier to remove it while installing the transfer case.
Installation:
Remove the stock transfer case from the stock tailhousing adapter. Make notes on the bolt location on the
stock tailhousing as these bolts are various lengths and are to be reused when installing the Atlas. The stock tailhousing
is retained along with the stock rubber crossmember support. Once the transfer case is removed, you'll see a seal located
in the stock tailhousing. This seal must be removed and discarded. Install the new oil seal in its place.
The kit comes with a new spud shaft which fits into the stock Toyota transmission 22 spline output shaft. This spud shaft
has a Jeep 23 male spline on the opposite side which fits into a standard 23 spline Atlas case. The spud shaft should be
installed onto the Atlas first, the collar portion on the shaft is a precision fit onto the Atlas input. You may find yourself tapping
on the end of the shaft to install it on the Atlas. Air can get trapped between the two shafts making this a slightly long process.
The adapter plate should now be installed onto the Atlas transfer case. The adapter plate indexes off of the Atlas front retainer
and is bolted on with the (6) 3/8"-16 flat head bolts. The stock transfer case had a 40 degree rotation, the new adapter plate
can offer you eight clocking options. All of these options may not be feasible due to transmission clearances and body
clearances. On the prototype vehicle we did, the 40 degree rotation was retained. The Atlas should be test fitted before the
adapter plate is secured to check for Atlas shift rail clearance on the transmission tailhousing; and the Atlas cable linkage
should also be test fitted on the unit to check for the same clearance issues. Once these areas of concern are checked,
check for any necessary clearances. The stock tailhousing and adapter plate may require clearance on some rotations. The
adapter plate should be installed. The bolts and bolt holes should be cleaned, red Loctited and torqued to 30 ft./lbs.
Once the adapter plate is secured and orientated correctly, you'll now need to couple it onto the back of the stock transmission
tailhousing. The stock tailhousing used two dowel pins to align the stock transfer case to the transmission. These dowel
pins must be retained into the stock tailhousing for proper alignment of the Atlas onto the transmission.
