This article mainly introduces caterpillar 3208 Diesel Truck Engine Checking Crossover Lever
Caterpillar Flash Files 2021.07 (Full Set)
NOTE: The crossover levers normally do not need checking unless one or more of the following conditions exist(after the timing is checked and theother corrections shown in Troubleshooting have been madej: A. The engine produces too much black smoke.
B. The engine runs rough because fuel delivery is not even.
C. Some cylinders continue to fire at fuel shutoff position.
D. The complete injection group is being reconditioned.
NOTICE Before any service work is done on this fuel system, the outside of the injection pump housing and all parts connected to it must be clean.
1. Remove the fuel shutoff solenoid (1), top cover(2)
of the fuel pump housing and the cover over the torque control group.
2. Remove the fuel that is in the injection pump housing and the governor housing.
3. Put the 3P1546 Calibration Pin(3) in calibration hole as shown.
4. Install the 5P6602 Adapter (7) as shown. Fasten it in position with a 1D4533 Bolt (5) and a 1D4538 Bolt
(6).
5. Put the 8S7271 Screw(4)(setscrew) in the hole over the calibration pin (3). Tighten the setscrew(4)
to 2.3 to 2.8 N·m(20 to 25 lb in) with the 2P8264
Socket.

6.Adjust low idle screw（8）to position lever（9）to 8.9
士1.0mm（35±.04in）from governor housing
boss.
7. Loosen the bolts that hold sleeve levers(A) and slide levers (A) out of the way.
8. Put gauge(13) on shatts(14) and(15). Slide gauge
(13) toward crossover levers(10) and(11) until dowel pin(12) goes into hole in gauge(13).
9. If dowel pin(12) must be lifted to go into the hole in gauge(13), the levers must be adjusted. See Adjustment Of Crossover Levers.
10. If gauge(13) must be lifted more than 0.20 mm(008 in) to let dowel pin(12) go into the hole in gauge(13), see Adjustment Of Crossover Levers.
11. To check the maximum clearance of 0.20 mm(008 in) that is acceptable under one side of gauge(13), hold the center and one side of gauge(13) against sleeve lever shatt(15). Use a feeler gauge to check clearance.
NOTE: After the checking of the crossover levers is complete, the two fuel injection pumps must be calibrated where sleeve levers have been moved to install 5P4209 Gauge. See Fuel Pump Calibration.
