简介
Follow this guide to disassemble and rebuild a leaky, clogged, or otherwise improperly-working spray gun for the Graco Paint Sprayer, model 17C325.
As you disassemble the spray gun, take the time to clean all the parts with soap, water, and a brush before reassembly, and replace any worn-out parts as needed, which are provided in the gun repair kit (part # 288817).
The filter is not included in the repair kit, but it may be a good idea to clean or replace it during the rebuild process.

Hi YURIY,
To help us improve the guide, can you please elaborate what would break? Any specific steps? Any extra detail would help. Thanks!
I can't break the tip loose. The piece that u screw the tip on to. I can't break it loose.
From factory, or after use, they are screwed in incredibaly tight. I coulnd't get the valve seat to budge. I'd avoid using an adjustable wrench since those sometimes come loose and strip the nut. The gun repair kit is about $70-$100. HD sells the entire gun for $150, which includes a 515 tip, orange spray tip guard, and new filter inside. Probably better to buy. Great guide though. If the needle can be cleaned to stop the post-release leak, then its probably OK to keep it. Else new gun may be a better option.
