4. Place seals and ball back in before screwing back onto the rod
5. Unscrew throat packing and push out packing
6. Take off cylinder
7. Take apart the filter housing
To begin Reassembly,
1. Replace filter back in place
2. Assemble throat packings by placing wave spring into the male gland before placing into housing
3. Screw in top part
4. Install into top part of the housing
5. Screw in barrel into the housing

I’m a retired shipyard worker and painter blaster. I rebuilt those 60:1-45:1-56:1kings. Gaco’s are very reliable.
Glad to see some good detailed videos on graco pumps. I tear down and rebuild these pumps everyday
Please let us know if there are any other videos we should make. Always looking for new ideas from those using our equipment every day. Thanks!
When in the field and experiencing a leak from the top of the cylinder, or a sticky ball in the piston, we've often put the sprayer on its back and removed the cylinder exposing the piston without dropping the whole lower leg. Because the throat packings are securely in place, guiding the piston, is there any real chance of damage when removing the cylinder against the direction of the lips of the piston packings? I suspect reinstalling it would be less risky because we're going in the direction of the lips. Thoughts?
Love y’all’s paint lines to. They are very abrasion resistant.
Great video! Well explained! Thanks!
Bilgileriniz icin tesekkur ederim

If we tight the piston rod and packings, i cannot able to insert inside the cylinder since packing gets enlarge or expanded so due to that cant able to insert and set piston inside. Request you to kindly assist and teach me to fix pls.

Great Video! Is there a full rebuild kit for this or a part number that you could share, or did I miss that? I need new packing's for the rod as well as the filter. The lower assembly is not creating any pressure, so I would like to rebuild it completely.
Woody Holloway Hi! Do you know what size lower/ pump is on your machine? You can then reference pages 27 - 29 in this manual:
www.graco.com/content/dam/graco/tech_documents/manuals/311/311762/311762EN-ZAH.pdf
Also might need a rod and cylinder as well. Please let us know if this helps. Thanks!
We install the pump back,but when we run test with thinner the pump stop/stuck...have you any solution for us.
Is the piston stuck? Did you take it apart again to check the shims and packings? I have a similar problem. The pump looses pressure on the down stroke whiling moving quickly then on the up stroke it moves at a steady slow speed.
What type of grease to you use for seals (o-rings)?
Wish mine was that easy 4 years of paint🤣
Thank you sar
