Foreword

YCA YC6B YC6J

This Instruction Manual introduces the YCA YC6B YC6J series construction engine about its structure and technical parameters, the technical specifications and data of its main accessories as well as the basics information on use and service. It also describes some common malfunctions and solutions.

YCA YC6B YC6J“ ”

Please read this manual carefully to understand and master the operation and maintenance requirements about YCA YC6B YC6J series construction engine prior to

putting the machine into operation and pay your particular attention to the Precautions for Safe Operation described below in order to enable the machine to bring its superior performance into full play and ensure its safe operation.

With continuous development and demand of the society, the engine will be uninterruptedly optimized and improved and its modified products will also be continuously increased. Except for especially great modifications in the design this manual will not be altered again. Therefore, after a certain period, there will be some discrepancies between the description in the manual and the actual engine, to which kindly ask our customers to pay due attention.

The manual gives a detailed description for the basic model engine only, and any modifications of it are not laid out to which we ask our customers to pay due attention and understand it well.

YuChai reserves the explanation right of this manual.

! Precautions for Safe Operation!

1.

Such parts as lubricating oil pressure sensing plug, water temperature sensing plug and alarm for too low lubricating oil pressure are very important. In case any failure, immediately replace it to ensure normal working of these parts, otherwise the crankshaft may be burned due to lack of the oil or the cylinder head may crack due to overheating resulted from lack of the water.

2.

After cleaning the oil filter or during the process of replacing filter gauze, reinstall the filter

only after refilling oil fully, and start the engine on idle running immediately after reinstallation; meantime, check if there is any sign of leakage to any filter. Correct the leaking filters or it may easily lead to crankshaft burn caused by oil shortage.

3. 3 5

Each time you start the vehicle, first start the engine on idle running for 3 to 5 minutes till the engine warms up and all gauges working in normal function, then start to move. Never put the vehicle to sudden acceleration from cold-start. For any dramatic speed-up on cold status will damage the instruments and their corresponding parts and components and accelerate the wear and tear of engine’s kinetic parts, consequently it will shorten the engine’s life cycle.

4. 3 5

Avoid any sudden stall and stop at high speed & high load status, the appropriate way is to gear down gradually and stop the vehicle after 3 5 minutes of engine idle running. Otherwise it will damage turbocharger and other moving parts and shorten engine service life consequently.

5.

Check often for the leakage and blockage of the intake piping and air cleaner to make them work normally. Do make adjustment or maintenance when there is leakage in the intake system and blockage in air cleaner, for they will damage the turbo-charger and cause the cylinder scoring, and will decrease the engine’s power at the same time , therefore maintain timely as the vehicle can be driven at pretty low speed .

6.

Start the engine on first gear, otherwise it may stop. 7.

Whenever the engine works abnormally, it shall be dealt with care. 8.

Don’t approach rotating components and directly touch the high temperature parts (such as exhaust pipe and turbocharger etc.) of the engine when you check it, don’t open the water tank cover immediately just after stop, for this may cause physical burn.

9. 50 60

Send the engine to a consignment technical service station of YuChai for run-in service

when it runs 50-60hour, or you will waive the warranty for this engine. 10.

Anti-freeze coolant shall be used in the cooling system; otherwise the consequent failure will not be included in the free warranty

11.

Customer is prohibited to insert or pull out the connectors. 12.

Water and any other cleaning agent are prohibited to use for washing and cleaning the engine.

13

Follow the instruction to drain water of fuel pre-filter, replace filter element assy. of pre-filter and filter element assy. of precision fuel filter.

14.

Make sure the ignition switch is turned off before dismounting and cutting off the battery.

15

Hoist and transport the engine in accordance with the precautions described on the outside the packaging case. The place for storage of the engine shall be well-ventilated, dry, clean and free of corrosive substances. See the mark on the package for preservation of the engine.

16.:

The basic information of the engine is on the nameplate, including: rated power, rated speed, series number, production date and implement standard. The nameplate of the engine is located at the top of the cylinder cover housing.

The engine type and ex-work number are printed on the platform in the middle of the cylinder lower margin.

18.

The safety warnings include user’s precaution, crankshaft steering/rotating danger and high temperature danger sticking on engine cover, clutch housing and cover on exhaust pipe respectively

19

Random documents are included in the package: user’s manual, parts list, tool list, certification and packing list. Please check after opening.
