Remove the automatic timer by screwing in the puller When disassembling the fuel injection pump, separate the bolt. If it takes longer, replace the priming pump as a set. Scratches on the sliding surface against 1 Thoroughly wash the plungers, and replace the plung- the roller pin are not a problem. Especially check the inlet side because air is likely to 2 Remove the piston. Then remove The fixing wire and seal are attached to the governor to limit the governor shaft assembly and washer.
If fuel comes out of the delivery side of the feed pump after about 25 strokes, the priming pump is normal. The use of a large capacity pump, however, gives over-torque and adverse exhaust color due to excessive fuel injection dur- ing medium speed high load operation. Inspect the air-tightness of each pipe and packing etc. M9961-H13021 Revision history list Page No. It optimizes fuel injection and combustion according to the air volume inside the cylinder for complete combustion and higher output.
The governor weight assembly, driven by the pump shaft end, controls the control rack of the fuel pump to adjust the fuel injection quan- tity. . Inspect all parts after disassembly and replace any parts as Note: 1. Make sure that the correct governor link necessary. Insert two drivers under the barrel flange. Revision date Reason for revision Revision outline Revised by page Rev.
Align the hole in the barrel with the hole in align the plunger flange with the slots in the pinion the collar, then set the straight pin in the holes of the and push the plunger until it is locked by the clip ring barrel and collar to fix them. Inspect and adjust output is timing, and 2 Engine overheats or emits large amount of smoke due to improper Inspect and adjust insufficient other failures too late injection timing. In each case, disassemble and repair. When using the high pressure pump, however, the injection volume at the equalized rack condition tends to decrease according to the rise of engine speed. Sure to use the standard thickness shim. The automatic timer adjusts the advancing angle auto- matically as follows: - When the speed is increased, the fly weight expands outward from the fly weight holder under centrifugal force. Note: Be careful not to damage the O-rings.
Check and adjust to bring it 1 Set the initial rack position of the boost compensator to the specified value. Engine's Defective injection 1 Knocking sounds caused by improper too early injection timing. Note: Mark each part to recall the original assembly. The T-shaped flange at the bottom of the plunger is fixed The plunger reciprocates in the plunger barrel with a in the grooves of the pinion sleeve, and the pinion is fixed stroke and is lapped for a precise fit. Screw the governor weight nut back in two or three times. Accordingly, a larger capacity pump is used.
Before starting reassembly, clean both the new mounting holes are used, and that it is parts and parts to be reused, and put them in order. . . . .
