Replacing Perkins engine parts seems straightforward — but small mistakes can lead to big damage. Many of our customers have shared stories of expensive repairs caused by simple errors.
Here are the 5 most common mistakes to avoid.
1. Not Verifying the OE Number or Engine Model
Parts look similar but may not fit. Always confirm your Perkins engine series (400, 1000, A4.236) or OE number before ordering.
2. Using Cheap, Low-Quality Gaskets & Seals
Low-grade gaskets leak quickly, causing oil loss, overheating, and contamination. Always use high-quality gasket sets.
3. Skipping Torque Specifications
Over-tightening or under-tightening bolts cracks cylinder heads, warps surfaces, or causes leaks. Follow factory torque specs.
4. Ignoring Air Bleeding in the Fuel System
After changing filters or fuel lines, air must be fully bled. Trapped air causes hard starting and poor performance.
5. Reusing Old Wear Parts During an Overhaul
When rebuilding an engine, don’t reuse old bearings, piston rings, or seals. This leads to rapid failure and a second teardown.
