- 14(3) Apply force (not enough to compress plunger spring) to plunger's bottom in axial direction, and measure dimension "KF" with dial gauge, as shown. (4) Determine the shim to be used by calculating difference between standard and measured dimensions. Refer to S.D.S. for "KF".[Example] When measured (dial gauge reading) value is 5.2 mm, "KF" - 5.2 mm = Shim thickness to be useda. When there are no shims available of a thickness which matches specified dimensions, use slightly thicker shims.b. Use selected shim with distributor head.c. Use the same size shim on each side of distributor head.d. Refer to S.D.S. for available service parts.
SEF855 - 15Adjustment of plunger dimensions (Measurement of dimension "K"). Dimension "K" is the distance from the end face of the distributor barrel to the end face of the plunger top, when the plunger is at the bottom dead center position. (1) Install parts as shown. (2) Using a dial gauge, measure dimension as shown.a. Do not install "spring" on driving disc.b. When inserting plunger and shim into cam disc, make sure drive pin is situated in groove at bottom of plunger.a. Rotate drive shaft so that plunger is set at bottom dead center.b. Securely mount distributor head with screws.
