Frequently asked questions
Will it fit my Yuchai YC6108ZQB diesel engine?

How often should I replace the turbocharger on my Yuchai YC6108ZQB diesel engine?
On the Yuchai YC6108ZQB diesel engine, often as long as the engine, 8,000 hours or more, when the oil and air filters are kept on schedule. Most turbos fail early from oil or dirt problems, not age.
What are the signs the turbocharger needs replacing?

Should I change the oil and filter as well?
Yes. Fit new oil and a new filter, and replace the oil feed and drain gaskets. Make sure the drain line is clear and runs downhill.
