Pinion Valve & Housing

1. Remove seals from pinion using a sharp knife. Cut diagonally, taking care to not damage groove ends.
2. Using pinion ring expansion sleeve tool No. 606602 or equivalent, to expand seals, install one in groove nearest to ball bearing race. Repeat procedure for other three seals.
3. Rings can then be compressed to original size by installing pinion ring compression sleeve tool No. 606603 or equivalent. If this tool is not available, rings will return to original size in one hour.
4. Install washer and U section seal, into pinion main housing. Ensure grooves in seal face upwards and seal flange fits snugly in groove.
