b. Generator Capacitor. Remove screw which

s e c u r e s lead to capacitor terminal and remove

screw and lock washer which secure capacitor to

generator frame. To install capacitor, reverse the

removal procedure.

c. Regulator Capacitor. Remove screw which

secures lead to capacitor terminal, and remove

screw and self-locking nut used to mount capacitor.

Withdraw capacitor. To install capacitor, reverse

the removal procedure.

d. Ignition Coil Capacitor. Remove screw which

secures lead to terminal, and remove cap screw, nut

and lock washer which secure capacitor to coil

mounting strap. To replace capacitor, reverse the

removal procedure.

e. Ignition Switch Capacitor. R e m o v e s c r e w

which secures lead to capacitor terminal. Remove

self-locking n u t s e c u r i n g c a p a c i t o r t o t r a c t o r

chassis. Withdraw capacitor. To replace capacitor,

reverse the removal procedure.

f. Coil to Distributor Lead. Grasp coil to

distributor lead firmly near coil, and pull lead free

from coil. Grasp lead firmly near distributor cap,

and pull lead free from cap. To install new lead,

reverse the removal procedure. Assure that nipples

(boots) on ends of lead form a good dust-tight seal

with coil and distributor cap.

g. Spark Plug Wires. Replace wires one at a time

to avoid wrong connections between distributor cap

and spark plugs. Grasp each wire firmly at

d i s t r i b u t o r cap, and pull wire free from cap.

Remove nipple (boot) from free end of wire. Pull

wire free from slot in ignition coil bracket. Grasp

wire firmly at spark plug terminal end, and pull

free from spark plug. To install wires, reverse the

removal procedure. Check that nipples (boots) on

wires at distributor cap form tight seals.

Capacitors

4-18.

Testing Suppression

Each of the suppression capacitors has a

capacitance rating of 0.10 uf. Use a capacitor tester

to check each capacitor after removal from tractor.
