MAINTENANCE GUIDE

- Make sure that the turbocharger is always lubricated.
- The oil filter needs to be cleaned or replaced regularly.

- Regularly check the air filter, clean and replace the filter element periodically.
- Remove the compressor housing and the turbine housing periodically, then clean the inner flows of the two impellers and two housings.
- Periodically check the tightness of the inlet pipe between the air filter and the turbocharger, between the turbocharger and the engine, otherwise it will cause loud noises and oil leakage.

• Lubricant requirements

– Lubricating oil grade: SJ/CH-4 (API) or A3/B3 (ACEC)

– Lubricating oil viscosity: 15W40 (Southern), 5W30 (Northern)

– Need to be filtered through an oil filter no larger than 5μm

​

• Pre-lubrication of the turbocharger is required in the following cases

– Excessive downtime

– replace with a new turbocharger

​

• After the engine starts, keep the engine running at idle speed for 3-5 minutes to ensure that the oil pressure meets the requirements of use

 

• Before shutting down the engine, keep the engine running at idle speed for 3-5 minutes to reduce the overall engine temperature

 

• It is strictly forbidden to use the operation method of "acceleration-flame-off-neutral coasting"

 

• It is strictly forbidden to use liquid-formed sealing gaskets, sealing strips, and sealants on the sealing surface of the turbocharger oil circuit
