Rebuilding a Honda Pilot engine "Top to Bottom"
"Parts"

 

The first and most important thing you need to do before starting on a project of this scope is to read the manual thoroughly, and understand EXACTLY what you are getting into. The pilot motor rebuild requires special tools, and patience in order to do the job right!

 

Here is the list of parts you will need.

reed cage gasket. (You may want to get a couple extra.)

1 each 19217-PA5-003

1 each 91201-148-003

right side cover balancer seal

1 each 91001-KA4-003

1 each 91201-402-015 
right side cover crank seal

 

1 each 91204-HEO-005

You will have to wait until you can measure the cylinder to see if what size piston you will need.
1 each 14100-KS7-831
(optional 1988 CR250 reed cage assembly. Nice upgrade.)
1 each 13000-HE0-010
Crank assembly (optional, replace/repair if old unit is worn or runout is excessive.)
1 tube of Yamabond, Hondabond, or equivalent
A light coat works great to seal reed cage gaskets.
