Replacing Yamaha T60 Input Oil Seals 

Step 1. Remove the two input seals from inside the water pump housing with a flathead screwdriver.

NOTE: Don’t push the screwdriver in too hard, as you may end up gouging the housing and cause it to leak. 

Step 2. Clean the water pump housing, then replace the O-ring that goes around it with a new one.

Step 3. Make note of the depth of where the two input seals were seated.

NOTE: Yamaha makes a special tool to drive the input seals to a certain depth, but without that specific tool, you should note the depth first before installing the new seals. 

Step 4. Insert the new input seals one-by-one by hand first, then using a bearing driver to press them into the same depth from where the old ones came out of.

NOTE: Whatever driver you’re using, make sure that it fits on the inside, but try to get as far to the outside as you can to where you’re not driving in on the center section. We used a 35mm bearing driver.

Step 5. Use a soft-blow hammer on the driver to tap the input seals into place.
