CCT Failure

[edit] Known problems
Early models suffered from premature failure of the cush drive, probably due to the power pulses of the big V-twin engine, but Honda rectified this with improved materials. The remaining weak point of the motorcycle is cam chain tensioner failure. Luckily, this failure rarely results in engine damage and simply requires replacement of the tensioner . Of the two tensioners, the front is the more likely to fail and, unfortunately, this is the more awkward of the two to replace. Replacement is comfortably within the capabilities of the competent home mechanic, but consequently the valve timing must also be checked

Not heard of that one before?

Well....Mine started to go and i consider myself lucky.....NO BLOOMIN LUCKY that I got it early enough to avoid any damage & just needed to change the CCT.

my front one failed and cost a bucket load of beer tokens to repair

I guess it depends.

Mine failed and was just noisey.

Others have failed and lunched entire engines.

The serious damage seems to occur in cases where the CCT goes, then the camchain wears through its guide retainer, and jumps off.

Is that right that you have to check the vavle timing? hoping to replace mine this weekend and already a little worried about doing them in the 1st place let alone having to set my own valve timings

Valve timing will remain the same after you have changed the CCT( presuming it is changed without the chain jumping a tooth).

If its valve clearances you are on about then they should be checked every 16000miles(i think), but to be honest if i was getting someone to change the cct's and they were doing it the "proper" way( ie: cam covers off ) then i would get them to check the clearances at the same time while the engine was apart.

Hope this helps( and is correct hahaha )

No. You must set the timing to the correct position for each piston before you remove the relavent tensioner

Genisis, go read the "how to". It'll keep you out of trouble and make the job easier

What he said

Read this and take note, cos the Haynes manual version tells you how to do it WRONG!

How to remove and refit CCT's on the firestorm

[genisis]

Yeah i have read that a couple of times, Just hadn't seen anything about Valve timing. I'm gong to attempt to fit them my self and as you said if I'm removing the Rocker Covers i might as well do the clearances.


I'll Keep you posted just in case i bugger it up completely

I followed the CCT sticky on here and I found it a pretty easy job and I'm not the most competant home mechanic.
Key is to read it...re-read it...and take your time. once finished....Turn it over 1/2 dozen times by hand before reconnecting the battery and starting it properly....Just in case

RedStormV....When you say the Haynes manual shows it wrong..In what way exactly and is it all versions or earlier ones ??
