Advance Adapters 50-0430 - Manual (Page 2)

Pulse Generator Installation:
Slide the reluctor ring over the 4L60E shaft installed in the transmission. Push the ring
completely onto the shaft until it bottoms out. Lightly snug the set screws for a "dry run". Trial
fit the 51-0405 adapter plate onto the back of the 4L60E transmission using two of the supplied
bolts. With the adapter bolted on the back of the transmission, install the 300619 reluctor sensor
into the adapter casting. The 300619 sensor should line up over the teeth of the reluctor clamp.
(If the clamp-on ring is not completely bottomed out, this may cause a miss-alignment with the
sensor). When you have confirmed the correct location of the shaft, remove the adapter housing.
Make sure you do not disturb the position of the clamp on the shaft. With the clamp now exposed,
tighten the set screw on the clamp. ( One piece reluctor, bolt torque 10 ft-lbs. ) Loctite is highly
recommended on these set screws.
You should now be ready for final installation of the 51-0405 casting. RTV Blue Silicone should be used to seal adapter
51-0405 to your 4L60E transmission. Use all of the supplied bolts for the casting and torque according to factory specs.
Next, screw the 300619 sensor completely into the 51-0405 casting. Be careful not to force
this sensor once it has contacted the shaft. Slowly back the sensor out of the hole and
with a feeler gauge. Check the gap between the sensor and the reluctor ring. This
gap should be around 0.010" to 0.012". Once 0.010" to 0.012" clearance is
obtained, Loctite the sensor into position.
You are now ready to bolt your conversion adapter to the 51-0405 kit.
NOTE: On a few applications, customers have not positioned the
clamp in the correct position which has caused interference
with the input shaft in the transfer case. If you try bolting the
conversion adapter up to the 51-0405 and find interference,
the spud shaft may be hitting the clamp on the reluctor.
ASSEMBLY PROCEDURES:
1.
Trial fit the 51-6800 adapter on the already installed 51-0405 casting. Check to see that the castings seat flush against
each other. Use two of the supplied bolts to temporarily hold these together.
2. Trial fit the transfer case to the adapter and transmission. Check for spline engagement and shaft depth into the input
coupler of the transfer case. If the transfer case does not mate flush against the casting,
DO NOT DRAW IT
TOGETHER WITH THE FASTENERS. SEVERE DAMAGE WILL OCCUR. This is not normally found when
replacing an AX15 manual transmission. If interference is detected, the output shaft must be shortened to a flush stickout
with reference to the casting.
On Automatic Torqueflite 999 applications where the factory output shaft does not
protrude beyond the stock adapter, the will need shaft modifications. Cutting the shaft will require a cut off disc
to cut the outer edges, and a hacksaw to cut through the center. If you are unsure about cutting, please call us toll free
at 1-800 350-2223. If you do not have the ability to cut your shaft, a 1" spacer is available (Part No. 51-0404).
4. Remove the 51-6800 adapter, then press the seal into the casting with the open side toward the transmission.
SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific types of conversions. Modifications to any of the
components will void any possible warranty or return privileges. If you do not fully understand the modifications or changes that will be required to complete
your conversion, we strongly recommend that you contact our sales department for more information. This Instruction Sheet is only to be used for the assembly
of Advance Adapter components. We recommend that a service manual pertaining to your vehicle be obtained for specific torque vales, wiring diagrams and
other related equipment. These manuals are normally available at automotive dealerships and parts stores.
