Title: how well is the allen key trick when adjusting timing belt tension
Post by: chitown on March 29, 2013, 09:17:07 PM
I did my belts on my 09 696 and it runs great.  except in certain rpms I get whining type noise. I know the belts are to tight because I have run into it as I do alot of timing belts on cars for work.  my question is I used the video from ca-cycle works and used the allen key method of checking tension.  I am going to go in and readjust them but just curious if any one else ran into this problem with that method. thanks

I did mine as well a couple of weeks ago. The allen key method as such is easy but after tensioning I got the same whining noises at certain rpms. I have been driving it since, the whining stays and I take the noises for granted, being a Duc. However, check your bearings properly to be sure that they are good, if so, no problems should occur.

thanks for that and the link.  I am going to take the covers off on sunday and just recheck the tension. I dont want to much tension on those bearing causing premature wear.  but if all is ok still I will drive it for a while and see if it diminishes.

I did my 24,000 and my 36,000 mile belt changes.  I used the Allen wrench tension check (Both Ducatisuite AND LT Snyder use this method) and I've not had any problems.  Bear in mind Synder's manual says a 5mm should fit but not a 6mm.  He also say GENTLY press up on the tension pulley with the 5mm in place to set tension.

IF the whirring remains, I would check your tension and roller pulley for smooth operation.  If you feel any roughness or non-smooth rolling, replace.  Again, that is from the Snyder book.

just readjusted belt tension and the noise is gone.  for what ever reason I could not even get close to getting my 5mm allen pushed passed.  they were real tight.  maybe next time I will start and run for a minute and check again with just leaving the covers off.

Chocolate usually stops whining.
