I’m looking at this question myself right now. When we got the bus the air ride seat worked but it was connected to a very loud aftermarket air compressor with a rats nest of wire. During the build we removed the air compressor and stored it in the shop. We finally finished everything else and I reinstalled the compressor. It doesn’t work. Oh, it turns on and produces a small amount of air but the tank never budges from 0 psi when plugged into the seat.
We want the driver’s seat on a swivel and we want air ride so we have two choices:
(1) Fix the current seat with a new compressor, find a swivel that will fit, add a seat cover.
(2) Buy a new seat that incorporates a swivel and a compressor.
Frankly, after looking at all the interfaces (I.e. fitment) it will take a lot of work to get option 1 to work. First you need a new compressor and all the air line connections. Then you need to find a swivel that will work not only with the standard International bolt pattern but with my existing seat. There are several swivel options out there for semi truck swivels (Bostrom makes one) but they often are designed to only fit that manufacturer’s seats. In other words, swivel are easier to find than swivels that will work with your seat.
Theses are the interfaces:
Truck body to swivel base
Swivel top to air-ride seat base
Air compressor to air-ride seat
All of this can be worked out but you might need to create interface plates for any interface that doesn’t fit (e.g., swivel for bostrom seat to interface plate to current seat).
If you want to buy a new seat that incorporates all features (swivel, air-ride) they are available but from high end manufacturers. For example:
Knoedler Air Chief Overstuffed Channeled Seat (choose your options) Knoedler Seat
This is a very nice seat but it’s over $3000.00. The great thing about this seat is that it incorporates both the compressor and the swivel mechanism. I’m still looking for a cheaper option. I could probably find a Bostrom seat that would work with their swivel.
If you’ve read this far thanks for your patience. I’m just trying to work out the best way to finish this up without costing an arm and a leg. I figured at least some of this discussion may be useful to others looking to replace their seat.
