- Опубликовано: 29 сен 2024
- part 2 of the valve clearances saga. Episode would of been too long to upload by itself, therefore I split it into 2 parts.
I put the Cams back in, Torque the cam caps and install the new ignition advancer.
Disclaimer: I am a mechanic, for the Royal Mail. This is how I was taught to check the clearances, 13 years ago at college. This is the second time I have done this procedure since then. I may have explained somethings incorrectly, I may have also named parts incorrectly. DO NOT take this for a hardcore 'how to' video.
I am happy to help out with any questions, I am happy to take advice too.

The service manual specifies that you insert the cam chain tensioner before torquing down the cam cap bearings. The haynes manual gets it wrong so please follow the official service manual. If there is any slack in the cam chain the cams will rotate when you torque down the cam cap bearing.
So to prevent this from happening you insert just the tensioner body.
Thing is to set the ratchet mechanism to 2 clicks less than what it was when you removed it, or, to 5 clicks out if you did not make a note of it. This will take out most of the cam chain slack but leave a little bit that is needed.
Once the cam bearing is torqued down, and the tensioner inner is inserted, you can very slowly rotate the timing rotor clockwise and listen for the cam chain tensioner taking the slack back out of the cam chain, this lets you know its working.
NOTE, before refitting the cam chain tensioner work it in and out with fresh engine oil so it works smoothly without feeling gritty.
I hope you’re ok with me pinning this comment to the top. Everyone will see it then.
I usually push the chain with my finger or a punch. Just to take up most of the slack. As you said, 5 clicks which is what I do. I don’t bother counting as I’d be putting too much tension on it when tightening the Cct.
Thanks for commenting, I will keep this in mind next time! Haha 👍🏼
@@8713Thomas No worries. Great job.
I thought u had to count 30 pins front to back on cam marks
Sounds like a fellow stokie? Or not far off anyway!
Cheadle! Haha
@@8713Thomas nice! I'm over in alsager, originally forsbrook near Cheadle 👍 Small world!
Would it be a good idea to mark the chain and the cam sprocket so you avoid trying to line it all back up and potentially put it out a tooth ??
Valid point. But, with the tensioner being installed correctly according to the procedure, the crank and cams all lined up, there shouldn’t be any problems. You’d torque it all up, rotate the crank 2-4 times to check timing again.
@@8713Thomas Sounds fair mate. You're a braver man than I am lol, but I will have to deep dive into mine at some point. My 2nd E2 bike has 58k Klms on the ODO and I'm not sure if the previous owner had the valve clearances checked. I am very handy and mechanically minded, just never tackled job like this before. Thanks for the videos
