When the timing gear backlash for a Roots-type blower has become excessive, the problem is properly repaired by __________.

🔍 Key Concepts

• Gear backlash in timing gears for a Roots blower and what causes it to become excessive • How matched gear sets work and why they are used in precision timing applications • Why temporary fixes (like shimming) can be risky in high‑speed rotating machinery

💭 Think About

• Think about whether wear usually happens on just one gear tooth set or on both meshing gears over time • Consider whether timing gears in a blower are typically installed as individual replacements or as matched pairs, and why that might matter for clearances • Ask yourself what the maker would recommend to restore proper tooth contact and timing accuracy, not just reduce noise

✅ Before You Answer

• Verify whether both gears share the load and wear together in normal operation • Check if timing gears are commonly supplied as matched sets to maintain correct backlash and tooth profile contact • Consider whether shimming and pinning is a standard permanent repair or more of a field expedient/temporary measure
