MAINTENANCE OF YOUR ENGINE
Unless major repair work is done on the engine, timing should not be required.
FUEL
INJECTION TIMING:
Basic tools required: (A) - 10 MM Socket wrench
(B) - 13 MM Socket wrench
(C) - 17 MM Open end wrench
(D) - 12 MM Box end wrench
(E) - 27 MM Socket (1-1/16")
Engine firing order - Two cylinder - 1 - 2
(Front
V belt end)
Three
cylinder - 1 - 2 - 3
Four cylinder - 1 - 3 - 4 - 2
1. Remove fuel lines from injector pump fittings on injector pump (Tool C).
2. Pull decompression lever so that it will remain in the decompression position. No decompres-
sion
lever on Model-12.
3. Open throttle fully.
4. Energize electric fuel pump and turn engine over with starter to ensure that fuel is coming
out of each injector pump opening. Have
clean rags around opening to soak up fuel.
5. Wipe off any fuel on injector pump body and the top of each injector opening.
6. Turn crankshaft over by hand, being careful not to damage spline on end of crankshaft.
Engine rotation will be clockwise.
STOP IMMEDIATELY at the first sign of fuel movement in
the injector pump
fuel fitting, for whichever injector pump is being checked. (No. 1 injector
pump is the closest to the
V-belt end of the engine).
7. Remove cover from
flywheel timing mark inspection hold located inside of left engine mount
(Tool B).
8. Check alignment of mark on flywheel with the timing pointer on the wall of the inspection
hole. The 1-FI mark on the flywheel represents fuel injection of No.1 cylinder.2-FI
represents No.2 cylinder, etc.
9. If timing pointer and the flywheel marking 1-FI is aligned then No.1 cylinder is properly tim-
ed for fuel injection and should require no adjustment. The same will be true for No.2, No. 3
and No. 4 cylinders
if the above steps are followed.
10.
In order to determine if timing is off, or if the injection pump is faulty, it is necessary to
recheck the timing for each
cylinder two or three times.
11 If there are variations in repeatability in the alignment of pOinter and timing mark, a faulty
fuel
injector pump may be suspected.
12.
If timing marks repeat to same location but are off 3/16" or more above or below the pointer,
this indicates that the engine must be retimed.
If alignment of the timing mark is not within 3/16" above or below the pointer, the above steps must be
taken to time the engine.
If the timing is found to be satisfactory, then reconnect all fuel lines and fit-
tings and tighten. The fuel system must be bled beforeh)the engine will operate properly. (See fuel
bleeding instructions on page 28).
