DRILLING AND TAPPING PROCEDURE

WARNING

Wear safety glasses or goggles while drilling. Flying debris could result in serious eye injury. (00565b)

NOTE

Perform the following procedure on both front and rear oxygen sensor bungs.

Drill the Hole

NOTE

Drilling material may cause damage to catalyst system if proper precaution IS NOT taken to prevent debris from entering exhaust system.
The use of mechanical fingers, coat hanger or welding rod tied to shop rag will ease insertion and removal of rag.

1.	Insert clean shop rag into each end of exhaust pipe past oxygen sensor bung. This will help stop and catch all drilling debris.
2.	Set drill press spindle speed to SLOWEST setting.
3.	Refer to Table 2. Install piloted drill bit (1) into drill press chuck.
4.	See Figure 2. With drill press NOT running: a. Position exhaust pipe (3) into drill press vise (2). NOTE Pilot tip of drill bit must be completely square and fully-inserted into bung. b. Lower drill press chuck and position piloted drill bit (1) into exhaust pipe bung. c. Clamp down drill press vise to exhaust pipe. d. Raise and lower drill press chuck to check for drill pattern.
5.	With drill press running: a. Apply cutting fluid to drill bit and hole as necessary. b. Drill through oxygen sensor bung.
6.	Repeat procedure for other oxygen sensor bung.
7.	Wipe off excessive drilling debris. Leave shop rags in exhaust pipe.

Tap the Hole

1.	See Figure 3. Assemble tap to tap handle: a. Insert tap (3) into tap handle (1). b. Secure tap with set screw (4) of tap handle. Ensure tap is oriented so that set screw engages the flat of the tap. c. Apply grease (2) to end of tap.
2.	See Figure 4. Position and clamp exhaust pipe (4) into bench vise (3). NOTE Pilot tip of tap (2) must be completely square and fully-inserted into bung.
3.	Insert pilot tip of tap (2) into oxygen sensor bung (1). NOTE Apply cutting fluid to tap and hole as necessary while tapping.
4.	Start tap by applying slight downward pressure while turning in a clockwise direction.
5.	Continue to turn tap clockwise until tap has bottomed out, as indicated by increased resistance. Do NOT force tap.
6.	Back tap out by turning tap counterclockwise, 1 - 2 turns, then blow out debris using low-pressure compressed air.
7.	Repeat Steps 5 and 6 until threads have been completely cut into oxygen sensor bung.
8.	Turn tap counterclockwise and remove tap. NOTE Tip end of exhaust pipe toward the ground when removing shop rags. This will assure cutting material debris will not fall into exhaust system.
9.	Blow off debris using low-pressure compressed air and remove exhaust pipe from bench vise.
10.	Remove shop rags from exhaust pipe.
11.	Clean off cutting fluid and grease: a. Position exhaust so fluid runs out of pipe. b. Use PJ1® cleaner or equivalent to remove all traces of contaminants from thread area.
