Crank Oil Seal Leak
Posted: Mon Oct 10, 2016 2:04 pm
Hi all,
just back from a quick run down to Provence to collect some Christmas cheer !!. Managed 2200 miles in 7 days so that gave the bike a good workout. Now then, problem.
Whilst giving her a good clean yesterday I noticed oil at the lower edge of the front timing chain cover. I removed the black plastic belt cover and this has confirmed the leak. Oil can be seen where it has collected in the casting recess where the alternator belt pully locates. I was in my dealers this morning and described what I have found. They are 99% sure that the problem is a failing crankshaft front oil seal.
Looking at my Haynes Manual replacement looks pretty straight forward and could be a job for the winter period. However, both Haynes and advice and info from other forums advise not attempting replacement without using the dedicated BMW special tools.
I would be grateful to hear if anyone has experience of this job such as, is it possible to replace the seal without removing the front cover from the engine. The Haynes method is to remove the cover in order to drift out the old seal, replace the cover then fit the new seal which does seem a long winded way if it is indeed possible to remove the old deal with the cover in situ using "Seal Picks".
Any info / advice appreciated.
