Dealer Service Information Bulletin 68-I-49 – New Turbo Hydra-Matic Pump Body Released for Service
Bulletin 68-I-49 — Pontiac Motor Division Dealer Service Information Bulletin, Section 7E, dated March 7, 1968. Attention: Service Manager.
Subject: New Turbo Hydra-Matic Pump Body Released for Service.
Short answer: A new Type 3 pump body (service part no. 8625954) and Type 2 pump cover are now used in production. Only the Type 3 body is released for service; the new Type 2 cover is not. The old Type 1 cover (part no. 8624982) can be used with either Type 1&2 or Type 3 bodies; however, the new Type 2 cover can only be used with the new Type 3 body.
A new (Type 2) pump cover and a new (Type 3) pump body are now being used in production. This new cover and body can be identified by the casting numbers stamped on their faces (see Fig. 1 in the scan below). However, only the new (Type 3) pump body is being released for service, under service part number 8625954 [Z] (Gp. No. 4.224); the new (Type 2) pump cover will not be released for service.
Replacement rules:
- If the car is equipped with the new type pump cover and body and it becomes necessary to replace only the pump body, its service replacement must be the new (Type 3) service body, part number 8625954.
- If the car is equipped with the new type pump cover and body and it becomes necessary to replace only the pump cover, it may be replaced with the old style (Type 1) cover, part number 8624982 [Z] (Gp. No. 4.224).
Summary: The new (Type 2) pump cover can be used only on the new (Type 3) pump body (8625954), while the old style (Type 1) pump cover may be used with either type of pump body (Type 1 & 2 — 8624981, or Type 3 — 8625954).
