'84 300TD Timing Chain replacement advise

I'm getting ready to replace the timing chaing at 240K miles.
The manual procedure describes removing the glow plugs.
I noticed the engine can be rotated smoothly enough with the plugs in (with 1/2" ratchet).....is there another reason to remove them for this job?

When connecting the new chain to the old one, using the master link with a clip would be nice....to keep the chain from following off during the rotation process. Since I have the tool (and no link with a clip), I was thinking of just partially pressing the link (that comes with the chain) on so it could be gently levered off with a screwdriver.

Any Thoughts?

Thanks for the advise.

For me the hardest part of the job is putting on the new link to pull the chain through, taking it off when the chain is through then putting it back on the new chain. The little side plate is a bugger till you figure out what tools work best.

I don't think you NEED to remove the GPs

I always use a sacrificial master link when rolling em in. Clamp it securely when using it to pull the chain through and then using another one for the final connection.

dsmess,

Use the link you removed from the old chain to connect the old chain to the new chain. Just use the center strap and not the side strap. When you get the new chain over the cam sprocket, clamp it on with 2 vice grip pliers or wire it in place until the new master link is in installed. That way it can't slip down into the engine and you have to go fishing.

Then slide out the old link and slide in the new masterlink when new chain is in place on the cam sprocket.

Removing the GP is not necessary. You should have a minimum of 2 people to do the job and 3 is better. One to turn the engine, one to guide the new chain over the cam sprocket to preserve the timing and one to keep tension on the old chain as it is coming out of the engine. It should take only about 5 minutes to roll in the new chain.

Always turn the engine by hand 2 revolutions after installing the timing chain to make sure the valves don't hit the pistons.
