REPLACEMENT OF THE PUMP BODY OIL SEAL ASSEMBLY - ALL 1982-85 THM 700-R4
TRANSMISSIONS
When replacing the pump body oil seal assembly on all THM 700-R4 transmissions, it is recommended that Loctite TM RC/609, or its equivalent, be
used. This compound, when applied according to the manufacturer's instructions, will aid in the retention of the seal in the pump body.
NOTE:
IT IS EXTREMELY IMPORTANT THAT DURING THE APPLICATION OF THIS COMPOUND TO THE SEAL AND BORE
THAT EXCESS COMPOUND DOES NOT GET INTO THE OIL DRAINBACK PASSAGE.
Use the following steps as a guide, along with the proper service manual, for the removal and installation of the oil seal assembly.
1.
Pry out old seal using a screwdriver or suitable puller.
2.
Inspect the seal bore for the following:
A.
Porosity or cracks - replace the pump body if either of these conditions are found.
B.
Nicks or burrs - use crocus cloth to polish but do not enlarge the bore.
3.
Clean the seal bore with a suitable solvent to insure that it is free of dirt and oil.
4.
Apply Loctite TM RC/609, or equivalent, to the mating surfaces of the new seal and seal bore per the sealant manufacturer's instructions.
5.
Install the new seal assembly using tool J-25016.
6.
Inspect the seal to insure that it is properly seated and the garter spring is in place.
7.
Allow the compound to fully cure according to the sealant manufacturer's recommendations.
