How often should I replace my Bobcat’s timing belt?

Bobcat/Deutz recommend timing belt replacement every 2,000-3,000 engine hours or 3-5 years, whichever comes first. Always inspect the belt during routine maintenance for signs of wear, cracking, or contamination. If in doubt, replace it—timing belt failure can destroy the engine and cost thousands in repairs.
