rear seal on wd45

Can someone give me some advice on the rear seal on a wd45. There are 2 sets of felt seals (one being smaller) Are they both supposed to go in ?? I have read how to install but am confused why there are 2. thanx john
 
Idk what the right answer is but I just put the big ones in my engine and it worked fine but mine is a d17 out of a gleaner.
 
The rear main seal is split. Top half goes in an aluminum housing bolted to the block and the bottom half goes in the rear main cap. There is at least one YouTube video on installing them. Follow it exactly, or the new one will leak too.

The large seal(s) are for the G-226 engine from a D-17 and the smaller seal(s) are for the W-201-226 engine used in WC-WD-WD45. You MUST glue them in place after squeezing them thinner in a shop vise and a couple blocks of wood. Use good 3M weather strip adhesive and do NOT cut them off shorter and use same glue on the seal tips and the paper H gaskets !! Wipe some grease on the inner surface when assembling for lube.
 
The good Dr covered it. Lot of kits come as a generic 226 kit. They have gaskets for all versions of the 201/226 and like Dr says, not all gaskets are needed for your application.
