I do not recall timing marks
(it has been 30 plus years)
but knowing Maytag I would expect so
I had the factory service book and it had a photo of what it should look like
I remember putting it back together I thought I was giving it extra clearance
it turned out the other end was now too close to the case and touched it
this resulted in a knock when in the wash cycle
it wasn't a hard sounding knock and fixing it would have mean a complete taking apart of the machine again
so, as the machine was 10 plus years old at that point, we decided to live with it and buy new if it failed
we sold the house, with the machine installed and still knocking, 6 years later
the machine was installed on the 2nd floor where the bedrooms were and
my wife told the new lady she liked the knock because it told her what cycle the machine was in
( a true making lemomaid put of lemons moment)
the house has gone through 4 owners since then
(2 were flippers)
and the machine was replaced by one of them because by then it was over 40 years old
the last I heard it was still washing stuff at a car detailing shop
and still knocking
I am amazed I remember that machine so well
but it was my first complete rebuild,
with factory books and tools,
and I learned a lot
