This is in response to Heinz's questions on Cloyes timing chain
instalation.Just before taking off to Mexico the other month my wife
hurt her back so while waiting for that to heal I ran a test on how
loose was the chain and decided it was a good time to make the switch. I
had a chain I Had picked up from Joe M. last year and now was the time
to install. While the Manual is usually good in describing how to do
things in this case it is poor and not even accurate ,as it says you
have to remove the oil pan and you don't have to, in fact you can't
remove the pan! Every thing can be done from the front-at least in my
case as I have already removed the large round metal and rubber spacer
between the radiator and the fan (not the fiberglass part attached to
the rad.) This gave enough room to work and get your head up in there to
be sure that you get the timing marks in the right place. It is a bit
tricky as the new chain goes in with absolutely no slack. I learned from
the experience of pressing the chain on and found that I was one cog
off, so had to pull it off
again.Take your time and eye ball it to be
sure you get the marks lined up correctly.
In my case I got some antifreeze into the oil pan so be very careful to
drain it out and keep any bits of dirt etc. from getting into the pan
when the area is opened at the front. I ended up in draining the oil pan
as well as having to do some mopping in there with rags but likely if
one got some rags in at the start it would be better and save the extra
work and mess. Also when draining antifreeze have back end of coach high
and after draining by lowering back end you might save some of the
antifreeze from draing foreword from the block.
As I recall I had to undo the front motor mount so you will need to find
a way to support the weight of the motor. I used some 2x4's on each side
of the motor on the vertical.
I was amazed at how it quieted down the motor,now having a tight chain.
I also find that my Ping Alert is much more accurate as it is not
picking up extraneous other noises in the motor.
Good luck.
