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).]
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 bleed screw. Turn screw (1) out until the button on the screw almost makes contact with the inside of the nozzle puller. Tilt the tool approximately 45° and put it over the nozzle.
2. Tilt the puller up so the inside lip of the puller is under the stepped diameter of the nozzle, and bleed screw (2) is in hole (A).
3. Turn screw (1) down until the button goes into the bolt hole for the nozzle hold down clamp.
4. Turn screw (1) to lift the nozzle out of its bore. If necessary, after the nozzle is loose in its bore, move it up and down to help loosen any carbon and make removal easier.
NOTE: If fuel injection nozzle removal is still difficult, it is permissible to use an FT1533 Nozzle Assembly Adapter with a 1P0074 Slide Hammer to remove the nozzle. A nozzle that is removed with the slide hammer can not normally be used again, and a new nozzle will need to be installed as a replacement. Refer to the Service Manual for nozzle removal procedure with the 1P0074 Slide Hammer, and for any nozzle inspection procedures.
3406 Engine Fuel Injection Nozzle (8N7006)
1. The tools shown above are needed to remove the fuel injection nozzles from these engines.
2. Disconnect the fuel line and remove bolt (1) from the fuel nozzle. Clamp (2) cannot be removed until the nozzle is lifted approximately 25.0 mm (1.00").
4. Put 6V6982 Tube (5) in position on the injector with the groove over the injector support bracket. Install washer (6) and nut (7). Remove the injector and the support bracket.
3406B Fuel Injection Nozzle and Adapter Removal
The tools shown above are needed to remove the fuel injection nozzles from these engines.
1. Disconnect and remove fuel line (1) for the fuel injection nozzle that is to be removed.
2. Remove retainer (2) from adapter (3).
6V4089 Reamer Assembly
The 6V4089 Reamer Assembly (1) is used to remove carbon from the nozzle bores on 1100, 3100, 3200 and 3300 Direct Injection Engines. Use a wrench or a tap driver T-handle to turn the reamer by hand to remove carbon from the bore. The reamer will remove only the carbon and will not remove any metal from the cylinder head.
