I have the same problems as every body else with MY 07 SERK ..at the 5,000 mile service they replaced the automatic compresion release.Last week i noticed a bad vibration and when i checked i found the rear cylinder was leaking oil .Took it back to the dealer and they ordered new head gaskets,I asked about the vibration and they told me it was the handlebar mounts, hard rubber in the foot boards and then maybe a loose exhaust .
   I told them about crank runout problem people are having and they said it is not likely.I asked the to check the runout and i would pay for the labour and as expected there was a problem ,the told me the runout was 32.5 which is way over .So the parts are ordered and will be in Thursday.The guys at my local dealership in National city are great guys and very helpfull
  I just hope Harley find a permant fix for the problem ,I have a 7 year warranty so i will just take it back every time i have a problem i still love my bike and am looking forward to some great rides

SPW,
Welcome to the site.  You might want to go and introduce yourself to everyone in the New Members thread.  I'm a little miffed at what "parts" they ordered when they found your crank run-out was way out of specs.  The only "part" they should be ordering is a new engine.  If they are going to split the cases and put a new crank in, have them weld it and true it and go with the Timken bearing.  Might as well get it right if that's what they're going to do.  But I'd be surprised if they go that route.  Previous owners that have had crank run-out problems have had their engines replaced.

Make sure the paperwork you get on warranty service spells out in detail what was done. Some of these dealers say as little as possible on the work order they give you when you pick up the bike so as to avoid lemon law claims

Thanks for the info will check on which parts tomorow how did the other owners get there engines replaced

 MOCO will NOT authorize a repair on a motor with a runout issue. This is what I was told by my dealer when my engine had to be replaced. I had it in two days after it was hand built and stamped with my vin #. No problems since !!!! KNOCK ON WOOD

This by far the largest number I have ever seen or heard of. I hope you get a new motor and  I am sure you will. You will be on the road a lot quicker that way.

Good luck on the repairs,

Someone did post .076" early on.

I never saw that one. This is crazy. How can HD let things like this go out on the street??

I'm not certain that complete engine replacement is still the MoCo's only repair option.  In fact I'm quite certain that at least one person reported having just the crankshaft replaced by his dealer.

If you prefer a complete engine versus a dealer repair, I would suggest that you let your dealer know that you will be contacting the MoCo to request a full replacement, enlist his support, and then call the MoCo direct.  As for which method, replacement or repair, would be the best way to go, that is a crap shoot.  If your dealer has a really good engine tech who can be trusted to do things right, it might be better in the long run to let him rebuild the engine with a new crank that they send out to be trued and welded.  You would have to pay for that, since the MoCo won't, but it would be well worth the cost IMHO.

 WOW !!! I cannot believe they would even consider this an option. Keep us updated as to what they do. I am really curious.

[sedyna]

mines in the shop with the same problem as we speak... oil pump failed. they checked the crank runout and she was out.. took out the oil pump. the dealer didnt want to get a new engine, they said it could be built better than the factory did.... i have a new crank and oil pump. Im sending the new crank out thanks to advice from guys on the site... www.darkhorsecrankworks.com

They replaced the crank in my bike last fall. They did check the runout on the new crank too and it was a little under .001". It was nice to know that this crank was fairly good -at least to start with. With a new motor it's hard to tell what the initial runout might be. I asked about welding and Timken, but they said those would void the w.....ty. Guess sooner or later I'm going to have to follow the trail that Hoist has blazed!

After all, it ain't rocket science!

Good luck with this motor bb! You might be fine!
