My Cylinder air guides don’t look right…
 
Every manual and book that I have shows a different arrangement than the guides that I pulled out of my engine.

I have a 1985 3.2 that appears to have never been taken apart before I started my tear down.

All of my guides have cut outs, including all 4 of the corner pieces.

The corner guides: one set of two is cut differently than the other set of two.

All of cut outs are punch cut with perfectly rounded inside corners, so I do not think that they have been modified by anyone.

Do I have two wrong air guides, or is this the right set up for my engine? If I do have the right guides, I am not sure which corners go where!

Any input appreciated.

Thanks, Dave

That kind of looks like yours.

Hi
Think the link below will help you understand the factory air guide modification for 1964 to 1977 engines:
(Production equivalent embodied on later engines like yours.)

What you have is correct. The works drawing has the blades going showing both sides of motor.
The 1 inch cutout on the centers goes to the outside, the notched ends go against the case.

Thanks guys- the Bentley manual and Wayne’s book must have been showing the older style. Everything I was looking at had one of the end guides with no cut-out.

Huge relief!

Yes, that is exactly what I’ve got. I need to get an ‘85 service manual…
