Every 2,000 Miles
Important: Do not allow oil or grease to get on or near the contact.
(a) Distributor Shaft
Some distributors are provided with a lubricator on the distributor shank. With DM4 and DM6 distributors, refill the lubricator cap with Acheson’s graphited grease grade GC, or an equivalent.
Lightly smear the cam with a very small amount of Mobilgrease No. 2 or, if this is not available, clean engine oil may be used. Some distributors have felt cam lubricators to which the lubricants should be applied.
(c) Cam Bearing
Pull the rotor off the top of the spindle and add a few drops of thin machine oil to lubricate the bearing. Do not remove the screw which is exposed to view as there is a clearance through which the oil passes between the screw and the inner face of the spindle. On some distributors the screw is drilled to passage of the oil
Replace the rotor correctly and push it on to the shaft as far as it will go, otherwise there is a risk of the moulded cap becoming burned or tracked.
(d) Automatic Timing Control
Carefully add a few drops of thin machine oil through the hole in the contact breaker base through which the cam passes. (Some types are provided with a hole in the contact breaker base plate, sometimes marked “OIL HERE,” through which the oil should be added).
(e) Contact Breaker Pivot
Place a small amount of Mobilgrease No. 2 or clean engine oil on the pivot on which the contact breaker lever works.
