Cant answer your questions directly. When I replaced mine I did it when I change oil so had no problem. Make sure you have a new gasket handy since the cover has a paper one and possibility of failure.
You will loose about a table spoon full of oil. A rag will take care of it. You have to tap the cover to break it loose . It has dowel pins for line up. Don't loose them. Mounted on the inside of the cover is the timming sensor that will have to be removed. Be careful not to damage the wires going to it. Mount sensor on new cover and reinstall.
Hey Pete.......WOW, that was a TON of useful information !! Many thanks to you !!
I didn't realize there was anything attached to the backside of it.
DaleC - I am going to order thru www.smithwarenetworks.net/Owl/specialtyitems.html
The photo is from their website and not a photo I had taken of 'mine'. Cost is $200 including a new gasket and chromed bolts. I think I'm going to order a front wheel at the same time. Hey, it's only money. :shock: Now all I have to decide on is what brand of tire to put on it. :roll:
