Titan Airless Sprayer IMPACT 410 RX-80 Spray Gun Seal Assembly Replacement

Difficulty

Moderate

Steps

Time Required

10 - 20 minutes

Introduction

Use this guide to replace the seal assembly on your RX-80 spray gun.

For more safety information, refer to the Operating Manual.

Tools

Step 1

Before you begin, make sure to follow the pressure relief procedure documented in the user manual before disassembling the spray gun.
Use an adjustable wrench to loosen the tip housing.

Step 3

Use an adjustable wrench to loosen the diffuser.

Step 4

Pull the diffuser straight off the seal assembly to remove it.

Step 5

Use an adjustable wrench to loosen the rear housing on the back of the spray gun.

Step 6

Pull the rear housing straight off the spray gun to remove it.

Step 7

Use a 3/8 inch socket to loosen the lock nut from the back of the spray gun.
Pull the lock nut straight off the spray gun to remove it.

Step 8

Use your fingers or a pick tool to remove the retractor plate and its two alignment pins from the spray gun.

Step 9

Pull the seal assembly through the front of the spray gun to remove it.
This may take a significant amount of force.
During reassembly, squeeze the trigger when reinstalling the seal assembly.

1st, lubricate seal assy. w/ "lithium-based grease" (IAW Operating Manual ~pg. 9); and 2) after speaking w/ Titan tech: TRIGGER MUST BE PULLED IN WHILE DIFFUSER IS BEING SCREWED IN AND TIGHTENED. This is CRITICAL. Diffuser has a tungsten insert and ball-end of seal assy. is stainless steel. If ball-end of seal assy. contacts diffuser under spring pressure while it's being turned in and tightened, a groove can very easily be carved into the brand new ball-end and it will almost always leak or leak soon. (So I was told.) Hope this helps.

There is a filter in the handle that needs to be checked. That disassembly is not pictured or described here.
