Ford Transmission Clutch Seal Install & Selective Retaining Ring Chart

Service manual page with numbered transmission rebuild steps, figures, and a selective retaining ring thickness specification table.

AI caption · Photo 98 of 126

This scanned page is from a Ford automatic transmission service procedure covering clutch assembly and seal installation. The left column shows a technician using a dial indicator with bracketry (Tool-4201-C) to check clearance on a clutch assembly (illustration D10561-B). If the measured clearance is out of specification, the procedure instructs installing the correct selective retaining ring and rechecking; a table lists four available retaining ring thicknesses ranging from 1.52-1.62mm (0.060-0.064 inch) up to 2.59-2.69mm (0.102-0.106 inch). Step 9 notes that scarf-cut input shaft seals must be installed with mating surfaces as shown, and that two scarf-cut input shaft seals should be installed on the forward clutch cylinder and shaft if the originals are damaged or missing. The right column covers the intermediate clutch: step 4 instructs coating the intermediate clutch piston outer seal, inner seal, and pump body sealing area with petroleum jelly, then installing the intermediate clutch piston using Intermediate Clutch Lip Seal Protector T80L-77005-A. Two illustrations (D10276-A and D14344-B) identify the piston bleed hole location and show the piston being installed with the seal protector tool. This page helps a rebuilder verify clutch pack clearance and correctly install input shaft and intermediate clutch piston seals.
