Deutz Diesel Engine Maintenance Tips

Mar. 21, 2018

5.1 Time table for maintenance

There is no need to repeat after following the maintenance schedule

Working items	Operating time h
Re-tighten the connecting belt and tension	30
Change the oil and oil filter element	30	125
Check valve clearance	30	125
	30	125

Repeat the maintenance procedure following the timetable below

Working items	Operating time h
Working items	250	500	1000
Clean up the air filter element 1)	x
Check and tension the V belt	x
Change the oil and oil filter element	x
Check valve clearance			x
Change the fuel filter element
Clean up the crankcase ventilation mechanism 2)

1) The change should be made earlier earlier in dusty place.

Wet air filter should be cleaned every 200 hours (at most)

2) Only under the circumstances where the crankcase ventilation mechanism does not intake the air.

The maintenance instructions for the backup condition and emergency.

If the diesel engine does not operate for weeks (eg, in winter), it must be sealed up (see 5.2.11).

Time period	Requirement
Every month	Trial running with load see 5.2.10
6 months	If the running time does not reach 500 hours after 6 months, the required maintenance procedure must be carried out during this period.
After 12 months	If the running time does not reach 1000 hours after 12 months, the required maintenance procedure of this period must be carried out during this period.

Overhaul

The reliability of the Deutz engine might be affected because of abrasion and corrosion. In order to avoid any working abmormity of the engine, we recommend the following overhaul. The first overhaul should be proceeded after the engine has runned for 2000 hours or after two years (running time less than 2000 hours).

Item	Running time
Check the nozzle	2000
Check compressive pressure	2000
Check bearing clearance of the water pump	5000
Check supercharger	5000
Check fuel injection pump	5000
Check cylinder head	5000
Check cylinder liner	10000
Clear the water jacket space of the water cooling exhaust pipe and check the corrosion	10000
Check connecting rod and main bearing	10000
Check piston	10000
Check the crankshaft	10000
Check the camshaft	10000
Check the two-stage balancing mechanism	10000
Check the drive gear	10000
Overhaul fuel injection pump	10000
Change oil pump	10000
Change the oil sealing of the crankshaft	10000
Change the damper	10000

Above overhaul require expertise and should be carried out by professionals.

5.2 maintenance procedure

5.2.1 cleaning up dry air filter

When the maintenance indicator of the filter shows a red signal or the engine performance is affected because of the resistance of the filter, clean the filter or change the filter element.

1. Dismount the main filter element.

2. Lay the end surface downwards and flap the filter element carefully. Or the filter element on clean ground and roll it to shake the dust off. Do not beat it forcibly.

3. Blow from the inside and outside the surface of the filter element with compressed air (less than 500kPa).

4. Clean up the sealing packing. It should be changed if there is any damage.

5. Check the dust outlet in the dust -discharging valve.

6. Reinstall. If the filter is mounted horizontally, place the dust-discharging valve vertically downward when mounting the cover.

Notice: The main filter element of a filter can only be cleaned up for at most 5 times. It must be changed after a year, and should be immediately changed if there is a damage. Mark the number of times which the main filter element has been cleaned or changed for in the exclusive marking column of the safe filter element. The safe filter element must be changed under following circumstance:

1) Main filter element has been maintained for 5 times

2) It has been used for 2 years.

3) As soon as the main filter element is maintained, the maintenance indicator will show immediately.

4) After the operation with a defective main filter element.

5) Safety filter element is not allowed to be cleaned.
