cambelt tensioner bearings
having changed the belts a few weeks ago, today was its first proper run out, after an hour or so i was noticing a strange grinding/squeek type noise.. which actually caused me to call recovery, didnt want to risk it further until i,d checked it out.
covers off and all looks ok, so started it again, no noise, nice and quiet (ish).. then as it gets warmer it came back.. anyone experience changing these, can new bearings be pressed into the casings or is it new case and carrier ?? |

Before you think about changing the bearings, Garry, check your belt tension isn't too tight as this is a known, if not widespread, problem on the Evo.
I posted this on an earlier thread in reply to someone experiencing a similar noise to yours: Quote:

cheers lud.
my fault entirely, belts too tight.... done em properly now as your guide, spot on, even checked them hot, couldnt honestly believe how much expansion there was to take up the slack... another step up the learning curve... |

Hello mate!
Hijacking your Thread to ask the same thing. Are the bearings to blame or should I check my tension (Horizontal is ok, Rear is squeaking) Here's a Video (695 not an evo) https://www.youtube.com/watch?v=-Nnhm6NX_y0 Last edited by Kcekelkai; 19-05-2017 at 07:41 PM.. |

I've not heard of 696s suffering this problem, but a lot of the components are shared so it is possible as the tensioner rollers are the same as the Evo's.
Don't forget that the vertical cylinder runs hotter than the horizontal, which can lead to the belt running tighter than the horizontal. So you might want to check the tension; a lot of people advise having a lower tension on the vertical belt to take this into account. The usual guidance, if you're using the Allen key method to check the tension, is to use a 5mm for the front belt and 6mm for the rear. Having said that, the Ducati workshop manual (for the Evo) shows the same tension on both cylinders. |

I guess that tells me that the rear is a bit on the tight side. I'll sort the tension and report if it is ok. It is deffo not bearings since ive opened both covers and the bearings on both cyls are rotating good. |

just going back to this, as still not quite happy, the bearings are only supplied as a complete unit, 80 sovs from rapido, has anyone actually just replaced the bearing itself, only so i know what to get before it gets stripped down.
cheers in advance. |
