INSTRUCTIONS FOR RETAINER REPLACEMENT
Your pump's retainer is locked into place by one of the two following methods. Determine which method was
used on your pump's retainer, then follow the appropriate steps to remove the old and install and stake the
new.
Method 1 - Retainer shows no sign of stake marks
1.
This retainer has been locked in place with a Loctite product. To replace it, a moderate amount of heat needs to
be applied to the cylinder nut (in the area of the retainer) to soften the existing Loctite allowing it to be removed.
2.
Install the new retainer into the cylinder nut and torque to 80/100 in. lbs. Note: Do not use a Loctite product
this time but stake the new retainer in place according to instructions in Step 3.
3.
To lock retainer into place, use a center punch positioned in the seam between the retainer and the cylinder nut
and stake the new retainer in two places approximately 180° apart.
Method 2 - Retainer has two stake marks in the seam between the retainer and the cylinder
nut
1.
For replacement of this retainer, the stake marks must be removed. Using a 1/8" or larger diameter drill bit,
remove the existing stakes by drilling a short distance into the stake marks. Remove the retainer.
2.
Install the new retainer into the cylinder nut and torque to 80/100 in. lbs.
3.
To lock retainer into place, use a center punch positioned in the seam between the retainer and the cylinder nut
and stake the new retainer in two places approximately 180° apart.
NOTE: Do not stake in the old stake marks.
