Are all Harley-davidson oil filter wrench the same size. Was looking on amazon and some have a slot cut in the side and they give a size. So I'm thinking it shows a size there must be different sizes.
The dealer ( not a Harley dealer) near here wants $99.00 just for an oil change.

 

If I'm not mistaken the slot cut on the side is to allow the tool to clear a wire coupling near the filter. Helps on the TC HO 103 engines.
As far as I know they are all the same size

 

Might depend on year/model, but mine fits both bikes (09/touring & 03/sportster).

 

I suggest you Google: KN171C. These cost about $10 and they are easy to use, disposable, and top quality. They are available painted for a few bucks less.

 

I use a strap wrench for the filter on my 96 wide glide. Available for less than $10.00 at Home Depot.

 

I only need the oil filter wrench to get the filter off. I will put it on the same way I have on car, trucks, my boat with a rubber glove hand tight. Always have wondered how they all tighten up after 3500 miles or so.
I order the filter wrench without the slop I can see that nothing is in the way to need the slotted one. Thanks everyone for helping this new old guy out. I'm sure to have more questions. I think I have read every post on this site. And I did find a Genuine Harley-Davidson Service Manual for Softails. So that will help.

 

The oil filter wrench that Harley sells, also fits my '06 ford fusion with cartridge filter
