Camshaft removal for valve shim change (paranoia question)

[Meuryn]

Hey everyone,

So, I decided to remove the camshaft / camshaft holders to access the shims rather than mess about with screwdrivers / any special tools. As far as I can tell, I didn't change anything when I put the camshafts back into position. However, I'm just wondering (read paranoid) about whether removing and reinstalling the camshafts could have affected anything? Is there anything I specifically needed to do when reinstalling them? I know that the timing is fine, but anything else that could have been affected?

Thanks in advance

I don't think so, not as long as your timing is set right and you put the cams and caps back where they came off.  A to A, B to B, etc.


Use the proper torque spec.

Just in case you didn't look, the shim tool is available on Amazon for about 12 bucks.  I don't know how long it took to remove the camshafts, but 12 bucks is easily worth the time/worry factor for me, especially if you change the clearances more than once.  I'm a complete noob when it comes to mechanical things, though, so YMMV may apply here.

I would be worried if removing the shafts might affect the clearances, too.

+1 on the tool. It works well. And I love tools;-) any excuse to buy!!!

Its really easy to mess stuff up when you remove the cams, if you don't know what you are doing. Make absolutely sure that the cams are in alignment (read a shop manual for the step by step). If I remember correctly you have to remove the cam chain tensioner before removing the cams, although I can't remember since I went to a manual cam chain tensioner.

Made sure that the cogs stayed in the 'notches' on the chain, so the timing, I'm assuming, has to be the same. The cam lobes also lined up correctly when I reached the RT mark on the timing rotor so I'm hoping we're all good. I'll double check with the service manual regardless.

In terms of the process, it really was very very easy, to be honest I can't think of how you'd muck it up as long as you ensure the camshafts 'cogs' stay slotted into their respective links on the camchain. Each camshaft is 4 bolts, pop them in and out with the camchain tensioner removed. Saves spending on a tool (£20 plus here in the UK) I don't need.

Thanks for all the advice, will double check the timing before turning the engine over
