LA Engine Lower Timing Gear and Seal Questions

Hi Guys,

I am Replacing the stock Old Timing Chain on my 318, Surprise...120,000 Miles and Lots of stretch and slop..

2 Questions..

1. Does the Lower Timing gear on the LA Engine Typically slide on pretty easy?
I have build many slant 6's and I always need a heavy duty Balancer puller and Gear puller to get those pieces off.
On the LA there is a crank Bolt to Hold all of that stuff on.. It just kind of surprised me how loose the fit was compared to what I am used to.


2. In the Timing Cover Gasket set, there is a Wool or felt piece.. (in the top of this picture) What is it for? I have not ever seen one before and was not sure where it belongs.



Thanks for the Help!

Greg
