After the clips are all removed, it is a simple matter to lift away the seat bottom upholstery and foam.
Sadly, the seat frame is often very rusty. The one in our photo is no exception! Look at the pile of rust flakes in front of this seat frame.
The rubber seat diaphragm is plainly visible as well and needs to be removed now.
Here’s your MGB seat frame in “bare” condition. In addition to the upholstery and foam, the cardboard seat back panel is removed. It is held in place with two small screws, which are easily removed.
After the seat frame is stripped bare, it should be carefully inspected for damage. Cracks in the tubing can be welded and reinforced. Seat adjusters that don’t work properly should be repaired (or possibly replaced from a donor seat).
If the seat frame is severely rusted, we recommend replacing it with a better one. Keep in mind that there is a lot of force exerted on the seat during hard acceleration! It would be extremely disappointing to go through the expense and labour of seat rebuilding only to have the frame break!
The seat frame consists of a seat back and seat bottom. They are held together with two bolts, washers, & nuts. They should be unbolted and separated for cleaning & renovation.
Unfortunately the seat latch & adjuster mechanisms are welded & riveted to the seat back frame. This makes repair or replacement difficult, though not impossible!
We have abrasive blasted our display frame to remove rust and then painted it. We recommend that you do the same if your frames are rusty. You don’t want to get abrasive material in the adjuster while doing this. Carefully “bag off” the adjuster assembly (cover it with plastic and tape over the edges) to prevent this from happening.
After cleaning & painting the frame pieces, it is time to start the reupholstering.
Here is the seat back frame, ready to go. It’s been blasted, painted, & cleaned up.
A new cardboard backboard has been installed.
Two little screws in the bottom and duct tape around the sides & top hold the backboard in place.
