Ignition current is .6-2.5 amperes at 6 volts with en- DISTRIBUTOR ———a gine running and 4.5 amperes at 6 volts with engine stopped. Coil is mounted on the back of the instrument board with the switch extending through to the driving | Z ul U compartment. Distributor Model 658-B. Breaker contacts separate .022 inch with breaker arm on lobe of cam. Set contact gap by loosening lock screw on stationary contact plate and turning eccentric adjusting screw until proper setting is secured. Resur- face contacts with a fine flat contact file or on a medium hard oilstone. Breaker arm spring tension is 17-21 ounces. Breaker uses two sets of contacts on a single four sided cam. Contacts open alternately at intervals of 45 degrees correspond- ing to 90 degrees of crankshaft rotation. This is the correct firing interval for the Gardner engine and breaker must be accurately set. See Timing. Distributor is semi-automatic. Maximum manual advance is 15. degrees (engine). Automatic advance begins at 500 R.P.M. and reaches a maximum of 17.5 degrees (engine) at 2000 RPM. Mounting: —Distributor is mounted in well on top of cylinder head. To remove dis- tributor, disconnect manual advance rod and breaker lead. Remove distributor head with cables in place. Remove manual advance stop screw and lift distrib- utor out. Oiling: —Fill the grease cup under the distributor head with medium cup grease and turn down one turn every two weeks or each 500 miles. Every 5000 miles re- move the rotor and saturate the wick oiler in the center of the shaft with light en- gine oil. Place a small bit of vaseline on the face of the breaker cam under the ber bumper of the contact arm. Timing :—Synchronization of Contacts:—Use Delco-Remy Tool, Part No. 820738, and follow directions on Page S-25. of the National Manual. Contacts can be syn- chronized without tool after distributor has been timed to engine by cranking en- gine over 90 degrees from firing position of piston No. 1 when piston No. 6 will reach firing position. The second set of contacts should separate at this point. If they do not, loosen lock screws and turn eccentric adjusting screw on bcabe plate until contacts begin to open. Tighten the lock screws and check the contact gap with the breaker arm on the lobe of the cam. If it is not within the limits of .018-.024 inch reset at .022 inch and repeat synchronization operation. Timing Distributor to Engine: —Breaker contacts begin to separate when the pis- ton entering power stroke reaches a position 6 degrees (on the flywheel) before top dead center with the spark lever ully attvannat i 2 =laia@: (|Ax> =J Ca © HORN BUTTON CONDENSER ‘ F/ / ti ‘ 1 i} ~ QO ®OQOOO©O®© © i Sen ~, oN SN ..
