What is a Craftsman Pressure Washer Pump Rebuild Kit?
Definition and Components
A Craftsman pressure washer pump rebuild kit is a comprehensive package containing all the essential parts needed to refurbish a pressure washer pump. These kits typically include:
- Seals and O-rings
- Pistons or plungers
- Valves and valve springs
- Gaskets
- Pump head components
- Bearings and bushings (if applicable)
- Hardware such as screws and clips
The exact contents can vary depending on the model and the specific pump type, but the goal is to replace worn or damaged parts to restore the pump’s original performance.
Why Use a Rebuild Kit?
Using a rebuild kit offers several advantages:
- Cost-effective alternative to replacing the entire pump
- Extends the lifespan of your pressure washer
- Restores pressure and flow rate
- Prevents leaks and inefficiencies
- Maintains the value of your equipment
Regular maintenance with rebuild kits can prevent major breakdowns, saving time and money in the long run.
Types of Craftsman Pressure Washer Pumps Suitable for Rebuild Kits
Axial vs. Triplex Pumps
Pressure washer pumps generally fall into two categories:
- Axial Pumps: Usually found on consumer-grade pressure washers, these are simpler in design, less durable, but easier to repair.
- Triplex Pumps: Commercial-grade pumps with three cylinders, offering higher pressure and durability but more complex to rebuild.
Craftsman pressure washers typically use axial or triplex pumps depending on the model. Rebuild kits are designed specifically for each pump type, so identifying your pump model is crucial before purchasing a kit.
Identifying Your Pump Model
Before buying a rebuild kit, determine your pump’s model number, which is usually found on a label attached to the pump or the pressure washer body. Common Craftsman pump models include:
- CAT (Cat Pump)
- AR (Annovi Reverberi)
- General pump models
Matching the kit to your pump model ensures compatibility and successful repairs.
