before doing this because of mileage you should check it for stetch - put
the crank on TDC, remove the cam cover and check the cam washer - it has a V
cut into it that should align with the mark on the cam tower - it'll be off
some if stretched - the amount is measured in degrees - I believe over 5 d
indicates need for change.
As preventive maintanence you might consider changing the tensioner also --

rumor has it that Tom wrote:
Contemplaing doing timing chain overdue at 270K miles. I have been doing
some research. It appears a chain buddy;, ie standby helper is required.
Can this job be done totally solo? I have not met any of my neighbors or
friends/wifes/kids or enemies who gives a rats a-- for my 77 300D or
would
be worthy or interested in helping.
Any thoughts please. Can it be done solo? Thanks

I did it solo - about 5 times.
The chain that came out of the box was too short. (!!!???!!??)
So I was _sure_ I did something wrong.
New chain in/old chain out; old in/new out; new in/old out, dropped end
down inside. *sigh*
Recovered chain end, installed old chain, removed injector pump,
replaced oil pan, ordered a _correct_ chain from Rusty.
Then - newer chain in/old chain out.
Piece of cake!
Just be sure you have the right size replacement chain (136 links),
and never drop it down inside!!
I did make a handy device to help me guide the new chain in, the old
chain out, and keep both of them in firm contact with the cam gear -
with one hand. The other hand could then work the rachet on the power
steering pump nut to turn the engine.
I've attached a photo. Sorry, archive...
Philip,
