Air Vents

[Robert Miller]

Good Day

Looking for ideas on replacement parts of the fresh air ports that are located on the corners of the right left lower windshield and above the rear seats in 66 260B. The exisitng ones the rubber has deteriorated to the point they will not shut off the air flow.

Thanks

Rob:

Mine where also in the same state. Instead of replacing them, I took them apart and replaced the rubber inside.
I bought an inner tube at a bicycle shop, the size that fits nicely is a 700 x 25. I believe its for a racing bike as the tube is very small.
In any case you need to buy some stainless steel wire as well to replace the wire holding the old rubber in place. I also glued the tube to both sides of the apparatus
first before twisting the wire over both ends of the tube. Make sure you cut the inner tube piece to the exact length as the old one. If its to long the vent will not stay in the position you put it.If its too short you will put to much stress on the plastic serrated ring causing failure of that part in the future.
The results are very good indeed, no problems with closing off the airflow anymore. Be careful not to lose the
plastic serrated band that is on the metal part of the vent. This is the part that keeps the vent in the partially open/closed position.

Good luck

I did something similar but I cut the finger off of a rubber glove... it fit perfectly

I was to replace the two rear vents with new rubber and the idea's worked well. In regards to the front upper vents (by the instrument panel) it looks they are inside the molding and the molding is riveted to the side of the fuselage any ideas on how to get them out?

Thanks

Rob: You have to take the window side moulding off. The the vent Assembly has a screw holding them into place, remove that screw and take unit out. The vent can then be taken out of the assembly by removing the screw holding them in place.

Good Luck,
