Yes, I have done a few. Not a hard job, just need to be careful. You will need to buy a pump pulley puller, Princess Auto sells them. The hardest part is getting the guts out of the case without damaging the case body. Not much to these things.
Thanks. That's what I was beginning to think.
I didn't need a puller as it is the first style with the key.
I found a good picture by picture illustration and it looks like if you take your time it shouldn't be too hard.
thanks for the encouragement.
Just have to order the correct kit.
