A new governor weight retainer assembly, referred to as an "Elastomer Insert Drive" (EID) will be used on 1985 model injection
pumps. This drive mechanism consists of six (6) Viton rubber inserts in a self-contained drive mechanism. It is interchangeable with
the rings used on 1978-84 model diesel injection pumps.
You should use the new EID assembly when the repair to one of these 1978-84 pumps involves removal of the governor weight
retainer assembly. You should never clean or soak the EID in a caustic solution. If necessary to clean, use diesel fuel or calibrating
fluid only. The time allowance for the repair is unchanged, although the actual labor time is slightly less.
It is imperative that pumps reworked with the EID assembly be identified to assist you in future diagnosis if a pump problem is
encountered. It is extremely difficult to tell the difference between the drives once they are installed in the pump. A metal tag with the
letter "E" is supplied in the package. Install this metal tag under the cover screw on the right front cover of the pump. The tag should
be placed between the flat washer and the star washer. The star washer should go next to the cover.
Pumps that are within the 12 month/12,000 mile warranty period that are sent to a Roosa Master Dealer will have the new EID
installed upon request. There will be a charge for this, which will be the added cost of the EID. Roosa Master Dealers, in addition to
the metal tag, will also
stamp the body of the pump with the letter "E". This identification will be located on top of the wrench boss on the front of the pump.
