This article introduces the maintenance and parts replacement cycle of the Deutz engine cooling system

This article introduces the maintenance and parts replacement cycle of the Deutz engine cooling system The coolants currently on the market are all prepared by the manufacturer and do not require users to add water. Please use antifreeze produced by regular manufacturers. Antifreeze produced by different manufacturers cannot be mixed. Antifreeze has excellent properties such as antifreeze in winter, anti-boiling in summer, anti-scaling and anti-corrosion all year round.

* Cylinder scuffing caused by insufficient cooling will be found near the piston pin hole on the piston skirt. 

 * No cylinder scuffing marks have been found on the upper part of the piston. * The material on the piston is stuck to the cylinder arm. 

* Cylinder scuffing marks have been found on the top and ring of the piston. 

 

 * The piston ring will be completely stuck in the piston ring groove.

Importance of changing the oil during the first maintenance of Deutz diesel engine

 Importance of the first maintenance of Deutz diesel engine

Oil change cycle and oil level check Place the engine and vehicle in a horizontal position, run at idle speed for 2 minutes before checking the oil level, and then stop.

Check the oil level and add oil to "Max" if necessary. If the oil level is only slightly above the "Min" minimum scale, oil must be added

The oil level must be between the upper and lower lines of the dipstick. 

 If the oil level is too low, it will cause serious damage to the engine.   

The oil must be changed during the first maintenance of a new car, and the oil should be changed every 10,000 km thereafter.

Excessive oil level will cause:

 *Oil overflow. 

*Increased oil temperature. 

 *Foam. *Increased air content in the oil leads to bearing damage.

   Lack of oil leads to bearing damage

Running the engine with insufficient oil will cause bearing damage due to lack of oil. 

*The leftmost bearing shows typical tin plating friction marks on the bearing. 

 * The connecting rod bearing shown in the middle is worn out later, and a melted metal dot can be seen    on the lead-copper layer

 * The metal dot is found embedded in the tin layer of the main bearing shown on the right 

* All the above bearings are from the same engine and cannot be repaired. 

 

Connecting rod bearing cap broken due to lack of oil: 

 

 

 

* Overheating of the connecting rod bearing leads to insufficient tension of the connecting rod bolt. 

 

  * Further leading to the breaking of the connecting rod bolt. 

 

 * Eventually causing serious damage.

 

Carbon deposits on the piston ring and in the piston ring groove: The cylinder pull caused by the piston ring stuck is caused by the following reasons

 

 * Unqualified engine oil quality or adding different engine oil

 

 * Failure to change the engine oil on time

How to adjust the fuel supply timing of Deutz engine 1013 series？

 For Deutz engine 1013 series, the method of adjusting the fuel supply timing is as follows: Open the 

 Deutz Serpic 2012 EPC Download & Installation Service Finial Version

inspection window on the side of the fuel injection pump and find the tappet corresponding to the plunger 

to be adjusted; Loosen the timing screw locking nut on the tappet; If the timing is delayed, screw out the 

timing screw a little, tighten it with the locking nut and try again; If the timing is advanced, screw in the 

timing screw a little, tighten it with the locking nut and try again (this situation is rare); After each 

 

adjustment, carefully turn the cam slowly to make the plunger rise to the highest point. Then, pry up the 

tail of the plunger with a screwdriver and measure the gap between the tail of the plunger and the head of 

the timing screw with a thickness gauge (feeler gauge). This gap must not be less than 0.4mm to prevent

the plunger from hitting the oil outlet valve seat and damaging the two sets of mating parts. If the timing 

requirements can only be met if the gap is less than 0.4mm, a new plunger mating part must be replaced.
