Feedback (all cases to To measure ) ( dd.mm.yy)
complaint:
Scraping , -grinding engine noise since 1500 1/min , which in the interior
is noticeable.
The noise can be good the gear housing or to the sump perceived are.
cause:
Sharp edges of the sprockets , or the timing chain is not running smoothly on Guide rails.
measure:
Important: Before beginning the repair is necessarily the availability of parts sure !
Attention: Please be sure to check before installing the part number of the supplied parts and possibly compare the two side rails with the system ! As part of the PuMA measure
Only the parts listed in the measure to be installed !
Caution: Note the modified setting high pressure pump to the crankshaft ! this Change is currently not documented in the official repair manual , but already in the series implemented.
For this purpose, please pay attention to the appendix!
Figure 1: Shows the current in the repair instructions " 1131052 both timing chains first ( N47 / N47S .) "
Good positioning of the crankshaft. The HDP is in accordance with the repair Manual positioned .
Picture 2 and 3: Rotate the crankshaft in the direction shown until piston is still a shelter
of 1 mm has .
Figure 4: Shows dugout before top dead center. Install lower timing chain now .
Caution : Remember setting the timing of the crankshaft to the camshaft unchanged ! only the position of the crankshaft is affected by HDP -described change of !
Three cases can be distinguished as follows :
Case 1:
For motors N47 N47DK0 , N47S , production period 01.03.2007 to 05.01.2009 . In case of customer complaint, the following components must be replaced :
- 11 21 7 803 479 replacement crankshaft with bearing shells .
Note: Only crankshafts with production date after the 5th 1 2009 use !
The production date of the crankshaft is stamped on the sprocket. (See Annex, page 1 )
Meaning of the digits :
- The first two digits represent the production line.
- The next six digits represent : Year (two digits) , month, day .
- The last 5 digits identify the unit number of the crankshaft.
The crankshaft reproduced in the Appendix on page 1 is thus 21 October 2009 been made .
- 11 41 7 797 896 for the chain drive of the oil pump.
- 13 52 8 572 504 timing chain below .
- 13 52 7 797 906 sprocket for driving the high pressure pump.
- 11 27 7 800 523 gear ( intermediate for the balance shafts ) .
- 11 27 7 802 575 gear ( balance shaft drive ) .
- 11 27 7 802 576 gear ( balance shaft drive ) .
- 11 31 8 572 503 timing chain above.
- 11 31 7 797 899 for timing chain guide rail above.
- 13 52 8 573 158 for timing chain guide rail below .
- 13 52 8 573 159 sliding rail for timing chain below .
- 11 31 8 576 201 chain tensioner for timing chain top
Note: The below is just damped timing chain tensioning and guide rails use ! (see Plant page 2) A shoring of only a damped rail is not permitted!
For the timing chain guide rail only without stiffening webs using up! (see System page 3) Note: The intermediate for the balance shafts in accordance with repair instructions exactly Set !
If the intermediate and the balance shafts are adjusted insufficient , the motor despite new crankshaft etc. produce sounds !
See repair manual 11 " replace crankshaft " 21 500th
Note: For vehicles in which in a previous repair already crankshaft was renewed :
These vehicles treated as described in " Case 2 " .
Case 2:
For motors N47 N47DK0 , N47S , N47T production period from 05.01.2009 - 01.03.2011
Replace the following components in the case of a customer complaint :
- 13 52 8 572 504 timing chain below .
- 13 52 7 797 906 sprocket for driving the high pressure pump.
- 11 31 8 572 503 timing chain above.
- 11 31 7 797 899 for timing chain guide rail above.
- 13 52 8 573 158 for timing chain guide rail below .
- 13 52 8 573 159 sliding rail for timing chain below .
- 11 31 8 576 201 chain tensioner for timing chain top
Note: The screw of the intermediate for the balance shafts must not solved more are !
Note: The below is just damped timing chain tensioning and guide rails use ! (see Plant page 2) A shoring of only a damped rail is not permitted!
For the timing chain guide rail only without stiffening webs using up! (see System page 3)
Note: For vehicles in respect of which a repair already the slide rails without Reinforcing bars were installed and replaced both timing chains : These vehicles treat as described in " Case 3 " .
Case 3:
For motors N47 , N47S , N47T from production period 01.03.2011 or has already taken place repairs with guide rails without stiffening ribs .
In case of customer complaint, replace the following components
- 13 52 8 572 504 timing chain below .
- 13 52 7 797 906 sprocket for driving the high pressure pump.
- 11 31 8 572 503 timing chain above.
- 13 52 8 573 158 for timing chain guide rail below .
- 13 52 8 573 159 sliding rail for timing chain below .
- 11 31 8 576 201 chain tensioner for timing chain top
Note: The below is just damped timing chain tensioning and guide rails use ! (see Plant page 2) . A sheeting of a single damped rail is not permitted!
Note: The target build status after repair is illustrated on page 4 of Appendix
