Help.. metalic knock / tap on right side

[Comfy Old Boots]

Can I ask something Bobble?

Could you tell the guide was broken before you removed the Head?

Amazing pictures. I Really appreciate being able to look at the parts in question

No I couldn't see it, I thought I heard the noise (tap) once when rotating the engine by hand, when Steptoe suggested it that made me decide to take the head off and have a look, he's not worshipped on here for nothing you know

Any ideas how your going to get the new one back on? Is it a sealed coupling that goes round the spindle?

Question is, which bit of the new rail are you going to cut to pop it onto the pin? Which exact angle Just suggesting that it could be on the arc of the guide rail?

I'll lend an ear to mine in the morning. Was it more of a click or a dragging sound? Would 20w 50 make this impossible to hear? Only messing, well done so far.

Thanks for taking the time and trouble to post, will save us all money should we have the same problem. Any idea what causes this failure anyone?? l

It's made it to my archives

One of those things I never have to do but very good to hear and see how to do it.

I'll just follow the advice on here from Steptoe = You file a tapered groove just smaller than the locating dowel into the mounting point of the chain guide, in the position where it gets the least force when in place. Then snap it in place onto the locating pin/dowel.

It all makes sense now, I did not understand what Steptoe meant in his post.
Again thank you both for time and trouble.. Steptoe do you know what causes this? is it preventable?

Good post, keep the pics coming, makes it much clearer, like to see the cut on the new blade when you've done it, sure the jobs going to be fine

Cant find any other picture thread on this particular job on the net, so it could become famous

 

[(RIP) Bobble]

Well today I have some good news... and some bad

My cam chain guide arrived yesterday along with some other stuff (head gasket etc) from Motorworks so I decided to get on with the job. First of all I had to decide where to cut the guide, after a bit of thought I got the Dremell out with a cutting disc attached, unfortunately once I had cut it, I tried it for fit, it slipped on with a firm push. At that point I remembered I hand't taken a photo so here is where I cut and the angles etc..


Now fitted..


Barrel on, remembering to pull the chain through, you may notice the cleaned off piston.. I couldn't resist a bit of scratching with a screwdriver whilst on the phone


Then time to put in some new blood..


Now for a little tip.. I was talking with Vern and he mentioned about taking out the slack in the chain before attaching the cam sprocket, now my first thought was to make it taught on the upper side (opposite side from the tensioner), the bit that the sprocket mounts on can be rotated slightly on either direction, enough for the same affect as being a tooth out. Anyway I fitted it, then put everything back together and started the engine.. just. Bollocks.. I had taken out the slack on the wrong side of the chain! Set the bike back up to TDC, off with the downpipes as I can't get the tensioner out with them in situ, take the cam sprocket off then take the slack out of the tensioner side, on with the sprocket, down pies and everything else then try again.

This time he started straight away.. Whahoooo :beer jug:

The bad news????


The bloody tap tap is still there I am now thinking that it's the cam / buckets. Back in the garage tomorrow. Talking to Vern this evening, he's had two cams go and between us we think it could be that.

On a positive note, the cam chain guide had to be replaced so it was still a job worth doing.

I hope all of the above reads ok, I know what I mean and hope I've got it written down ok

Thats a real bummer, but as you said 'it was broken anyway' as per my earlier post, please check cam follower for pitting of the case hardening and role push rod over something absolutley flat and check for any anomalise.It sounds to me the noise is at valve speed.I'll wait for the flak to come.

 

[Comfy Old Boots]

It's like trying to raise the titanic. Ear plugs me ...

 

[Vern]

Hands up all those people with a set of cams, carriers, pushrods and buckets sat on the shelf

I think I might put them on the FS&W to see if there is any interest in them

After doing some looking about, I believe the 1100's are different to the 1150. I do need to confirm this though

Here's one i've posted previously in here - Odd that the otherside of this engine (the L/H side) was in perfect condition.

Knocking noise from the R/H side - R1100 50K miles.

Cause = Worn cams, cam followers, cam/rocker holder and rocker arms.

The cylinder head after all the rocker gear and camshaft has been removed



Cam/rocker holder.


Cam and cam followers.


Camshaft.





Cam followers in the holder.



Cam followers


New cams and followers

eek

Wonder if it got really hot / oil starved or something - the brown staining looks interesting

 

[(RIP) Bobble]

Well I've just removed the valve gear and guess what I've found....... bloody nothing! the cam lobes and buckets are mint, no signs of wear, the only thing to do now is to check the pushrods as they are the older design to see if the ends are loose. Anybody have any other suggestions on what it could be?

 

[Timolgra]

When you had it apart were cleaning the piston crown did you check the rings and glooves in case they've stretched? (the grooves)....also that there was no small end play?


Trouble is that listening to your vid again it does sound like top end, there's no marks and everything is correct in the rocker cover?

The tensioners are definately ok?

We're with you on this
