Damaged Camshaft

[speighty58]

Hi peeps,

My valve adjustment saga has taken a bit of bad turn.

Putting the Inlet camshaft back in or when i took it out, I must have caught it on the side of the engine or maybe when i was removing the timing tool
because as I was rotating the engine to recheck the clearances - i noticed this.

Which is better shown in this picture:

I found the missing piece in the top of the engine.

So rather annoyed with myself as you can imagine - but neither the less I ordered a replacement part.

2 days later the Inlet kit arrives - new camshaft and sprocket. - Result you'd all say.

Well I would have too - but when i went to assemble the camshaft sprocket onto the camshaft, i noticed both parts are different from which ones I had taken out.
Closer inspection and a call to a triumph dealer showed that i had the correct part numbers.
So i looked into it again - and still the parts dont fit together - so I have the dealer check direct with triumph after showing the following pictures!

If you look closely - you can see that the new camshaft sprocket has a 26mm centre, but the supplied sprocket is 30mm

And Triumph today confirmed that an incorrect sprocket had been supplied - with the correct part number on the bag ... no wonder I was confused!!!
So, they are going to spend me a replacement sprocket .... when its in stock .... ooh in about 3 weeks. 

But, what I have yet to have an answer on is the whether th new camshaft correct?
Again, its the correct part number , it fits perfectly in the engine,  BUT the camshaft end is different to the original.

The original camshaft end is 28mm
The new camshaft end is 26mm

Old

And when i do get the new parts, there's an excellent change that'll Ihave have to reshim the intakes again.


So i guess the moral of this story is ... when you take the camshaft out to replace shims ..... be very very gentle with them.

Also - has anyone here replaced their camshaft?

I had the same type of camshaft crack, when I incorrectly positioned the intake cam during my camshaft timing checking, while doing my 60k mile service.
I was able to complete the checking & adjustment by temporarily securing the broken end piece back onto the cam & correctly proceeding. Afterwards, I took the broken pieces off & set them aside. So, my intake cam it turning with a broken slotted end, just fine
I have subsequently purchased a replacement camshaft & installing it at the 80k mile service. I thought that I'd buy the camshaft while they were still readily available.
Note: there are two versions available, based on engine number.
I'd be doing a valve lash check then(80k miles) anyway. So, a good time to do the swap.
So, it is sitting on a shelf in my shop until then.
While I haven't installed it, I could pull it out of the box & measure it, if need be.
Let me know..

hi Larry,

thanks for the offer, but should be ok.

I am curious about "Note: there are two versions available, based on engine number."

Where on earth did you find this info out?

I've been using the WOT link and Fowlers and im sure I can only find one part listing for the camshaft.
