If the timing on a piece of equipment is 19° to 21° B.T.D.C. and the The addition or removal of 0.05 mm (0.002 in.) of shim, changes the injection timing by approximately 0.087 rad. (0.5°).. Shims are available in thicknesses of 0.20mm, 0.25 mm, 0.30 mm, and 0.35mm. Combine shims for adjustments. What size and how shims are needed to set Injection Timing of 0.33 to 0.37 rad. 19° to 21° B.T.D.C.?
