STEP 1
STEP 1
Prepare your transmission on a stable surface and gather the following:
Renn27 supplied:
Transmission spacer
Transmission drilling jig
Transmission hardware kit
Transmission spacer kit
User supplied:
G96 transmission
Power drill
1/4" drill
15mm wrenches (2x)
Center punch
Straight metal pick (scribe)
STEP 2
STEP 2
Take note of the multi wall construction of your transmission, you will be drilling through either one or both of these walls in the following steps.
Insert one of the transmission dowel pins into the left side of the transmission.
Mount the transmission spacer to the transmission and bolt it securely using the vacant hole below the dowel pin on the left side.
Mount the transmission drilling jig using the two M10 holes on the right side of the transmission as shown, and bolt it securely to the transmission
Insert the supplied 18mm drill into your power drill chuck.
STEP 3
STEP 3
Time to drill! Triple check your setup and review step 2 again. Sure this is simple, but you are about to drill into your 911's transmission!
Insert the drill into the bushing on the drilling jig and steadily drill through both walls of the transmission. Remember the construction of the transmission. You're drilling through thin walls of aluminum, a lighter pressure here will help to prevent stalling your drill or gouging.
Once you have successfully drilled through both walls, remove the transmission drilling jig, transmission spacer, hardware and dowel pin.
STEP 4
STEP 4
Insert the engine speed sensor into your newly drilled hole. Angle it so the wire is heading forward, away from the engine mating surface as shown.
Scribe into the transmission the mounting hole for the sensor. You will use this scribe in the next step to locate the center of the mounting hole.
STEP 5
STEP 5
Using a center punch, punch a dimple in the center of the scribed hole.
Insert a 1/4" drill into your power drill
STEP 6
STEP 6
Using your dimple as a locator, drill through the first wall of the transmission with the 1/4" drill.
STEP 7
STEP 7
Insert the M6 set screw through the newly drilled 1/4" hole. Ensure the set screw's hex head is accessible from the outside of the transmission.
Insert the M6 nut between the walls of the transmission and screw it into the set screw until it bottoms out.
STEP 8
STEP 8
Thread the M6 Nylock nut onto the set screw and tighten it sandwiching the transmission and M6 nuts; creating a stable stud out of the set screw.
You can now insert the engine speed sensor into the transmission and secure it to the stud using the final m6 nut.
