This is the locking nib that holds the tensioner retracted till you release it. Twist and push the nibbed part against the spring pressure fully into the tensioner, then hold it in a clockwise position while slightly releasing pressure on it so that it springs out slightly and engages the...
Sorted now thanks guys. Someone on another forum put me right about the last cut out where the nibs are - I played about with it and it held in nicely.
The plastic retainer holds it in while you mount it - and releases the tension when you retract it. These online forums are absolutely...
I can't find my control panel to manage my attachments so here is an edited image of the earlier one that refers to the nibs which stop the tensioner from retracting. I can push and twist the nibbed component up inside the tube/piston freehand but it will not compress when inserted into it's...
Aha - I see the pressurising hole now AJ, thanks.
There is another one that I have referred to as a breather - which probably lets the excess pressure escape whilst doubling up as a spray directly to the rear of the chain.
I too think the red plastic component holds the unit retracted - but...
I have had a bit more of a Google and found the item below which shows the tensioner piston much deeper into the cyliner of the tensioner body than my new one will go which is a bit worrying.
I aint no enginnering expert but the piston assembly seems to be much more complicated that is needed...
Well 'er indoors just got in with the new tensioner assembly. It's spring tensioned rather than hydraulic - maybe that's the "update"?
The pack also has a red plastic thing in it which I at first assumed was some sort of setting device. Anyone know what it's for please?
I don't know if I can...
I don't suppose anyone could be precise as to how the oil is delivered to said tensioner/chain could they please? It'd give a better idea of what pipes or channels channels to thoroughly degunge or push through etc.
Point noted micranut - and thanks for the input. I usually take what mechanics who have their hand out for money with a pinch of salt though mate.
I'll go with the top tensioner inspection first though as it's relatively cheap and quick, no trouble to just put the plate back afterwards. The...
