Product Overview
The hand primer is used to fill the low-pressure fuel circuit and push air out after a filter change, empty tank or fuel-line repair. If the primer cannot build resistance, leaks around the plunger or allows fuel to drain back, starting can become difficult after service or overnight parking.
Cat application data for the 569-4682 priming-pump family includes the 528B, 530B, D4H TSK II and D5H TSK II among many other legacy machines, making that reference useful when confirming the original pump.
Key Features & Performance
- Manual bleeding after diesel fuel-system service
- Relevant Cat forestry/skidder application family
- Helps restore reliable prime when the original hand pump is worn
- Associated with Cat 569-4682 application data
Part Numbers & Specifications
- Component: fuel hand priming/feed pump
- Associated Cat reference: 569-4682 where configuration matches
Before You Order
Match the installed primer and filter-head configuration. A machine that repeatedly loses prime can also have suction-side air leaks, damaged hoses or filter-seal problems.
Frequently Asked Questions
Is this the same as the injection pump?
No. It is a manual priming/feed component on the low-pressure side.
Why does the engine start poorly after a filter change?
Air in the fuel circuit may need to be purged before the injection system receives solid fuel.
What if the primer never gets firm?
Check for an air leak, stuck check valve, empty supply or a worn primer.
