Use these part numbers as a selection reference alongside the drawing and individual product listings.
Order by individual part number: Grouped numbers above identify separate products. Do not assume the thrust washers are interchangeable or supplied together.
Match the Component Before Ordering
Start with the model and serial number on your sprayer. Locate the component in the assembly drawing, compare its part number and check the required quantity. A diagram callout identifies a position rather than the number of pieces included in a purchase.
Review the product contents before adding an item to your cart. A gear, washer, knob or mounting component should be treated as an individual replacement unless its listing expressly includes additional parts.
If the existing part number differs from the current listing, confirm the replacement relationship before ordering. Similar dimensions or appearance alone do not establish a correct fit.
Plan the Repair Around a Confirmed Diagnosis
Unusual drive noise, interrupted operation or difficulty adjusting pressure can have several causes. Have the affected system inspected before deciding which component to replace. A new pressure knob does not establish that an internal control fault has been repaired.
Have gear engagement, associated washers and mounting conditions checked during drive repairs.
Identify whether the problem involves the external knob or another part of the control system.
Check for missing or damaged hardware and follow the specified installation order.
Service preparation: Follow the sprayer pressure-relief procedure and disconnect power before opening the equipment. Use the specified lubrication, assembly and service instructions. Electrical diagnosis and internal repairs should be performed by a qualified technician.

Titan 550xc Gear Box Assembly FAQ
Review these selection and repair questions before purchasing.
Does an individual listing include the complete gear box assembly?
Check the individual product contents. A separately listed component does not imply that a complete gearbox, motor or control system is included.
Can I replace only the damaged component?
An individual replacement may be appropriate after inspection confirms the fault and the condition of associated parts. Follow the service procedure for the repair.
Are the different thrust washers interchangeable?
Do not assume interchangeability. Match each washer to its specified part number and position in the assembly.
Does unstable spray pressure prove that the gearbox is damaged?
No. Pressure problems require diagnosis across the relevant sprayer systems. Confirm the cause before purchasing drive or control components.
What information should I provide for fitment help?
Provide your sprayer model, serial number, existing part number and the diagram position or a clear photograph of the component.
