SUBJECT: NEW OIL PUMP AND SPACER ASSEMBLY
MODELS AFFECTED: 1984 CIMARRONS WITH THM 125C AUTOMATIC TRANSAXLE
FIGURE 3 - THM 125C TRANSMISSION I.D. NAMEPLATE:
Starting in May, 1984 with transaxle numbers 84 CA 2921 and 84 CB 240974 (refer to Figure 3), a new oil pump drive shaft and spacer assembly, pump shaft bearing and seal assembly, and control valve and pump assembly went into production on 1984 Cimarrons equipped with THM 125C automatic transaxles.
The new parts provide easier and improved assembly procedures.
FIGURE 1 - FORMER OIL PUMP DRIVE SHAFT AND SPACER ASSEMBLY:
FIGURE 2 - NEW OIL PUMP DRIVE SHAFT AND SPACER ASSEMBLY:
The former parts (Figure 1) are not interchangeable with the new parts (Figure 2) listed above for the following reasons:
1. The new oil pump drive shaft and spacer assembly has a thinner spacer and a longer bearing journal diameter to accommodate the new pump shaft bearing and seal assembly (Figure 2).
2. The new pump shaft bearing and seal assembly was also made longer in length to accommodate the seal as part of the bearing assembly (Figure 2).
3. The new control valve and pump assemblies were changed to accommodate the new oil pump drive shaft and roller pump shaft bearing and seal assemblies.
If the transaxle being serviced has a serial number lower than those listed in the first paragraph, refer to the 1984 parts list book. If the serial number is the same or larger, it will have the following new parts:
