Has anyone installed timing chain guide rails?

How do you keep from dropping the slippery suckers down into the engine and how do you get past the tight timing chain on the left head?

Start at the left head (driver's side if LHD), be sure to mark the cam sprocket and chain with paint, so everything can be lined up upon assembly. Once the paint is dry, loosen the cam sprocket bolt, then unbolt the tensioner on the right side of the block. Using a mallet tap the cam sprocket till it comes free of the cam shaft. I just wired the chain to the closest fixed object to hold it upward so nothing slipped internally. I remove the lower pin first, then work on the upper pin, when the upper pin is about to come free, just grab ahold of the guide, soon as the pin comes free you'll be able to slide the old guide out. Replace both guides, put the sprocket back in the chain and place it on the cam shaft. As long as the marks you painted line up, everything should be fine as the cam shaft has a woodruff key and can only go on one way. The other side you don't need to remove the cam sprocket. Once the guides are in and the tensioner is bolted in place tighten the cam bolt to 100nm (I think).

Mike, you are a lifesaver, as always. I enjoy reading your posts.
Is it easy to feed in the new chain? I am a little leary about doing it. My first time and all. Thanks again, Mike

Rolling in a new chain was a cake walk. The important thing is to use a guide or zip straps to ensure the infeed AND out flow of old chain stay in constant contact with the cam sprocket on the right side (passenger). Took about an hour to roll the chain in, would have only been 25-30 minutes if I had used the guide.

If you don't keep both feeds in contact with the sprocket, you are sure to jump time. If you catch it when it happens, you can correct it as you go, if not, you'll get jammed up with valve/piston interference.

I have a running diary of what I've been doing to the 560 in the Open Forum, I discussed the guides and rolling in the chain. I was advised to do the guides prior to rolling the chain, so I did and I offer the same advice.

Read your posts on rolling in the chain. Will try to do it as well as you did. Very helpful about the ties and cam jumping. Congratulations on your progress on 560. Thanks again
