Nerves about timing chain

Recommended Posts

Hey guys,

After watching the ZT video and his emphasis on not letting the screw driver wedged between the chain and gear has been making me nervous about doing this. Anyone have any helpful hints or anything about doing this?

Joey,

I'm not sure what the tape says about a screwdriver, but I did this years ago. When I did it, I used a piece of wood that I fashioned into a wedge. This held the chain against the side of the block and the sprocket on the crankshaft. I drilled a hole in the top of the wedge and put thick thread/rope through it so I could pull it out when I put the head back on. You might also look around on the internet for a mfg. plastic piece that does the exact same thing as the homemade wedge I used. Hope this helps. It's really not as bad as it sounds to do this, go for it!

Bob

heres a visual:

Maybe later i'll take a pic of the one I made for reference.

Edit:

I added the picture of mine. I notice mine is alot shorter than most people's... I actually had no problem with mine, or getting it out of the chain when I was done.

Here's a scan of mine. I cut it out of some scrap 3/4" pine I had lying around.

Just put a strong piece of cord through the hole at the top so you can be sure to pull it out. This one fits VERY snug, probably more snug than is necessary. That's just the way it turned out. Trim to fit :)

Anyone have a pic of where to wedge this? I haven't taken that part off yet, but I'm guessing wedge the wedge between the side of the chain/sprocket and engine block?

i took a screwdriver and wrapped it with ducktape to the point where its nice and snug. It worked out great and will continue with this technique.:D

Straight down the timing cover onto the top of the crankshaft gear so the chain is on either side of the wedge.

PS, I think you need a shop manual before you do this job. It will show you things like this and give you torque specs and other helpful information.

These pictures show the use of a chain wedge. The second one shows what the wedge does. You don't have to remove the front cover. (Unless you don't use the wedge)

I have used a long screwdriver (18") with good success. Stick the handle down and rotate it for a snug fit. The other end of the screwdriver sticks up far enough to have access to remove it later.
