Someone help me out here. Which locking nut is he talking about. I see 4-nylock nuts holding on the tensioner assembly, and one large nylock nut holding the bearing itself. I don't see any nuts/bolts that look like they would adjust the position of the belt tension. http://www.cameragear.com/ec/timing.htm "- Each cam belt has a tensioner bearing that is attached to a tensioner bearing assembly. On those assemblies are self locking (nylock) nuts that lock the tensioner in place. These nuts need to be loosened, the tensioners retracted and the nuts retightened with the tensioners compressed. Be careful not to assert axial loads on the tensioners, as they tend to be quite fragile that way. I usually use a lever of some sort (pry bar) to compress the tensioner, but don't lever it by the roller bearing!" Maybe my question is how do I retract the tensioners?
