Cam Chain Tensioner bits

Hi AndyD,

as Nurse Julie said, great we are both working on engines at the moment. //great pictures, looks like your horse shoe has wear at the top, now i'm wondering if mine is the same and that explains the few metals bits in the sump. i'll check to morrow.

did you have any metal bits in the sump filter?

ka-ja:
Check the crankcase in the cam chain area (tunnel) for chain marks.

Bryanj:
Yup, had a 750 once where the oil leak was from where the cam chain had worn a hole through the casting. Its a long recovery journey Gloucester to Newcastle(upon Tyne) and back in a day

AndyD:
Many thanks all,
Had a happy session in the garage with files and Dremel and horseshoe now moves really freely so that's a real result (money saved to spend elsewhere no doubt!).
Final question re the cam chain tensioner - I assume the two dampers shown in the parts book either end of the slipper are sitting inside the two end 'cups' - all looks OK so do these need replacing or are they generally OK to leave alone?

Waffey - will be interesting to see how both engines get on.
I got this bike as a basket case in many pieces and the engine was part-dismantled so I couldn't check for any debris in the filter etc. Just going through everything as carefully as I can to see what needs fixing and so far it doesn't look too bad to my inexperienced eyes.
The previous owner had taken off the sump, cylinder head and a few other parts, had them blasted and then gave up and boxed it all up so it's a mish-mash of bits at the moment.

Cheers,
Andy

If they are brittle or showing any cracks they will need replacing  ;)
