When a thickness gauge is inserted between the speed lever and the full speed adjusting bolt and the speed lever is moved from the idle side to the full side.
Confirm no continuity using a thickness gauge t = 0.3.
Confirm no continuity using a thickness gauge t = 0.1.
(2)Idle side switch ON.
When a thickness gauge is inserted between the speed lever and the idle adjusting bolt and the speed lever is moved from the full side to the idle side.
Confirm no continuity using a thickness gauge t = 1.1.
Confirm no continuity using a thickness gauge t = 0.5.
2. Procedures for adjustment
(1)Standard position for Cam (159226-8100), stamping mark M, is explained in above illustration.
(2)Fix the microswitch body in the position shown in the figure above. (The microswitch is free.)
(3)Full side adjustment
Adjust using screw B to satisfy the adjustment specifications (1) above.
(4)Idle side confirmation
Move the speed lever from the full side to the idle side and confirm the above adjustment specification (2).
(5)When the idle side is not as specified, replace the cam (stamping S or L) and repeat adjustment from procedure 2.(2) above.

Introduction
The 6V7020 Nozzle Puller Group can be used as a replacement for the five nozzle puller groups (6V4054, 6V4061, 6V6976, 6V6980 and 6V6981) that are used to remove fuel injection nozzles from the above engines. Some of the parts in the separate tool groups are the same, but in the 6V7020 Nozzle Puller Group only one of each item is included. The 6V7020 Nozzle Puller Group also has several parts and tools that are not in the other five puller groups. See the specific Service Manual nozzle removal procedure. See the information that follows for tool operation.1100, 3100, and 3200 Engine Fuel Injection Nozzles (9L6969, 9L7883, 9L8965, 9L9263, 9N3299, 9N3700, 9N3979, 1W5829)
1. To remove the fuel nozzles from the above engines, disassemble 6V6976 Nozzle Puller Group (1). 2. The tool parts shown above will be needed for nozzle removal.3. Disconnect and remove the rocker shaft, see the Service Manual for procedure. 4. Disconnect fuel line (2) and nozzle fuel line (3), and remove adapter (4) from the cylinder head. Remove bolt (5) and the clamp. 5. Install 6V4151 Leg (6) in the hole with threads where the rocker shaft was fastened. Install 6V4149 Jaw (7) and 6V4152 Screw (8) on fuel nozzle (9). [Jaw (7) will slide into notches in nozzle (9).] 6. Install 6V4150 Leg (10) in 6V4153 Plate (11) and install the plate over leg (6) and screw (8). 7. Install the nut and the washer on screw (8), and using a wrench as shown, remove the nozzle.3300 Engine Fuel Injection Nozzles (7N0449)
1. The tool parts shown above are needed to remove the fuel injection nozzles from this model engine.2. Disconnect the fuel lines and remove the nozzle hold down clamp from both the nozzle to be removed and the nozzle next to it. 3. Install 6V4151 Leg (1) next to the nozzle to be removed. Install 6V4150 Leg (2) in the hole with threads in it by the next nozzle. Put 6V4149 Jaw (3) and 6V4152 Screw (4) on the injector that is to be removed. 4. Put 6V4054 Puller (5) on legs (1) and (2) and install 0S1618 Bolt (6) as shown. Install 1B4206 Nut (7) and 2S5658 Washer on screw (4). Remove the injector.3204 Engine Fuel Injection Nozzles (1W3996)
1. Loosen fuel line (1) and move adapter (2) to get clearance for nozzle removal. Remove bolt (3) and the clamp. 2. Install 6V4152 Screw (4) and 6V6978 Head (5) on the nozzle. Install the remainder of the parts of the nozzle puller group as shown. 3. Be sure 6V6979 Leg (6) is on top of the rocker shaft mount bolt (7). Use a wrench to hold screw (4) so it will not turn while the injector is being removed.3300 Engine Fuel Injection Nozzles (8N7001, 8N7002, 8N7003, 8N7005)
The 6V6980 Nozzle Puller Group is used to remove the fuel injection nozzles for these engines. 1. Disconnect the fuel line and remove the hold down clamp and bolt from the nozzle, but do not remove the nozzle
