Arba galima rasti yuotube.com ivedus i paieska BMW N47 timing chain ir rasit daug video medziagos.
Problema liecia visus N47 variklius.
Defektas nepriklauso nuo ridos gali buti 8000 gali buti ir 180 000.

Ar jau kas keitet grandine ir kiek tai kanavo ?

Cia reikia keisti itempejus ir variklio grandine, bei grandine, kuri suka tepalo siurbli. Ir keisti kuo greiciau, nes trukus grandinei, ne tik reikes voztuvus keisti, bet ir lyginti velenelius. Ir tai ne tik N47 varikliu beda, tai visu BMW naujesniu dyzeliu beda. Tik nepamenu kaip cia grandine stovi, ar is priekio motoro, ar is galo, nes yra ir atvirkstiniu motoru, kur grandines stovi gale, t.y prie dezes. I kelis tukstancius litu sutilpsi:)

Butum susidures nekalbetum nesamoniu, nes zinotum apatines zvaigzdutes kaina. Ji keiciasi kartu su alkuniniu velenu.

Tai jeigu toks viska zinantis meistras esi, bent jau butum zinojes ir dares tokius dalykus. Nezinau ka tu cia sneki , brolau, bet stai visos schemos ir kainos:

krastoj vien alkuninis virs 3k

Yra oficialus BMW dokumentas apie sia problema.

The Service Measure covers:
'N47, N47S, N47T, slipping noises in the engine, timing chain scraping'

From:
'01/03/07 - 01/03/11'

Cause:
'Sharp edges on the chain wheels or the timing chain does not run evenly over the sliding rails'

There are two distinct methods of dealing with the problem depending on build date.

N47, N47DK0, N47S, production period 01.03.2007 to 05.01.2009:
Renew:
- 11 21 7 803 479 Exchange crankshaft with bearing shells [Crank must be manufactured after 05/01/2009] >> this suggests that all cranks prior to that build have questionable sprockets??
- 11 41 7 797 896 Chain for the oil pump drive.
- 11 31 8 506 652 Bottom timing chain.
- 13 52 7 797 906 Sprocket for the high pressure pump drive.

teko susidurti su m47, ARUNAS teisus

N47

aga kaltas, tiesiog raides klaviaturoje salia

O jei keiciant grandine su itempejais ir zvaigzdutem alkuninio nekeisti? Na ta prasme apatine zvaigzdute palikti.. Zingsnis jau neatitiks?!

Tai kad ta alkuninio zvaigzde vienas is kaltininku del ko grandine sueina saibom.
