Installing a Harley o-ring manifold
The old style harley manifolds are a pain to install, an extra pair of hands can be a big help. Here’s one way to do it alone. There is half a groove on the manifold and the other half on the head, so the o-rings won’t stay on either part. So, first roll the o-rings up on manifold past where they should be.
Now you can roll one side down in place without the other falling off.
Install the clamp on that side to hold everything in place.
Now you roll the other side into the groove.
Of course the better way is to not use the stock o-rings at all. You can buy spacers that can be glued to the head and the manifold in the o-ring groove. This allows you to use the more modern band type seals and band clamps.
