Manifold Heater Valve

[Author nameAuthor names are only available to PAS members.]

Does anyone have suggestions about how best to address the stuck heater valve on my Model B? I’m wondering if there are any good schematics or photos of this unit, as I believe mine has been modified with some non-Pierce parts.

So far, I’ve heated/cooled this assembly and used a number of penetrating oils, but haven’t had much luck in freeing it. This has been going on for a couple of months. I address one system or another, and then come back to this valve and try to coax it free once again.

By the looks of the porcelain, this manifold was running rather hot in the past. I wonder if a lean condition was at fault?

Thanks in advance!

Used my inductive heater and Ferrosol to resolve this issue. Was able to also confirm the shutter integrity and movement by removing the exhaust pipe plug and using a borescope/inspection camera.

 

Does anyone have a photo of a Model B with the rod/end connection to this manifold shutter?

Thanks in advance!

Carl,

These photos are both of 1930 Bs. Two different methods of attaching the rod. I’m not sure which is correct.

Carl,

Here is a photo of my 1930 model B rod attachment.  Not a great photo, but  hope

it helps.  The return spring attaches to the distributor base.
