i5 10v cam sprocket -- how tight to turn?

[Andrei Kogan <abk@phy.duke.edu>]

Hello,

I hope I haven't drove the entire list crazy yet by all the questions about
the front of the engine. I got the new waterpump and the belt on , and now
I am ready to start assemblying things. There was one thing that really got
me worrying and I would like to hear some comments.

When I was putting the new belt on, i found that I needed to ajust the
alignment of the cam sprocket by about 1 tooth. I noticed that the cam was
REALLY hard to turn. I can move it with both hands on the sprocket, but
there is a very noticeable resistance to turning. I haven't checked how it
felt before I took the sprocket  off ( needed to in order to get the rear
belt cover off) , since the old belt was on all the time. I ended up using
a ratchet with the 19 mm on the bolt to turn it in a controlled way by the
amount I needed.

I distinctly remember, on a 4K engine, the cam sprocket can be quite easily
turned by hand with the timing belt off. This one feels much, much tighter.

Did I do something incorrectly? I have visions of a valve grinding into the
top of a piston somewhere inside the engine... I am certain I never rotated
the top and the bottom of the engine out of sinc except maybe for the slack
in the 2084 itself, but it should be totally safe, shouldn't it ?

Please let me know what you think, I would like to hear from you before I
try to run the engine.

Many thanks to Tony and others who responded to me last night regarding the
Idler pulley business.
