2007-2018 Mercedes Sprinter Swivel Installation Instructions

1. Disconnect the Positive (+) battery terminal in the driver's side footwell. (See your owner's manual to find this disconnect)

*In vans with electrical seats, the seat must be moved for and aft using the electric motor to gain access to all the hardware. Only after the hardware is sufficiently loosened should the battery then be disconnected and the seat unplugged.

Important - If you neglect to do this before disconnecting the wiring under your seat, it will trip a code that must be cleared at a dealership.

2. Slide the seat all the way forward in it's tracks. Now cut, remove and discard the foam pedestal cover. Be careful not to damage the wires.

3. Carefully disconnect the wire clips. Take a picture if necessary to remember the correct reinstallation orientation.

4. Remove the seat belt hardware plastic cover by gently prying it away from the plastic skirting. 

 

 

 

 

 

 

 

 

 

 

5. Use a T-50 Torx tool to remove the seat belt retainer bolt. Remove the seat belt end from the bolt and reinstall the bolt to 35 ft. lbs. Reinstall the plastic cover. 

6. Slide the seat all the way back on the sliders and remove the two front factory seat mounting bolts using a 12 point 11mm socket.

7. Slide the seat all the way forward and remove the rear bolts with the same socket. 

8. Carefully remove the seat from the pedestal and lay on a soft surface to protect the upholstery. Take care not to damage the wires or plastic clips that are attached to the seat and the seat base.

9. With the seat laid on it's side, mark the cut lines as pictured below. You can use a piece of tape as a guide marking 2.75" from the bottom of the skirting. Proceed to trim the plastic with aviation snips or a cutting disc. Sandpaper can be use to clean up the cut edge. This step is done on the inside and outside of both seats to allow the seat to swivel.

 

 10. Place the seat swivel on the seat base with the large hole towards the inside of the vehicle and the plunger nut towards the rear of the vehicle.

11. Feed the wires up through through the hole in the swivel.

12. Twist the swivel approx. 20 degrees from the bottom to expose the counter sunk mounting holes. You may need to loosen the center 6 nuts & bolts slightly using two 11mm wrenches to allow easy swiveling of the upper and lower plates.

13. Use the supplied 10mm x 1.5 button head bolt and nyloc nut to attach the seat belt to the supplied seat belt bracket.

14. Place the seat belt bracket as shown in the picture over the rear, outer hole in the pedestal.

 

15. Attach the swivel to the pedestal using the longer 1.5 x 30mm bolt for the hole with the seat belt bracket and the 1.5 x 20mm bolts for the remaining 3 holes. Do not completely tighten at this time.

16. Thread the locking cam mechanism into the weld nut on the rear of the pedestal allowing roughly 1/16" of pin showing through the bottom plate. Be careful not to thread the pin so far that it drags on the lower plate. Snug the nut on the mechanism but take care not to overtighten as this could cause binding.

17. Swivel the the top plate forward until the pin drops into the locating hole and check the fitment.

18. Insert the stainless support bracket between the pedestal and lower plate in the front outer corner of the pedestal. Push it in all the way flush with the swivel base by pinching together the upper and lower swivel plates while you tighten the hardware.

*If you have aftermarket Scheel-Mann seats installed, it is advisable to cut 1/8" of material off the top portion of this bracket to ensure fitment.

19. Tighten the hardware connecting the swivel to the pedestal incrementally moving around the base. Doing so will help make the pedestal, that is typically out of square, conform to the seat swivel. The heads of the bolts should be flush or slightly below the surface of the swivel and tightened to 35 ft. lbs.

20. Release the locking cam mechanism and turn the swivel slightly to allow the bolts to come up through the bottom of the upper swivel plate.

21. Carefully place the seat on the swivel taking care of the wires and connectors.

22. Slide the seat all the way forward on the seat rails. Use the supplied 1.5 x 20mm bolts and attach the rear of the seat rails to the upper swivel plate. The nuts will rest on the seat rails and the bolts will come up through the upper swivel plate. Slide the seat all the way back and repeat for the front bolts and nuts. Tighten all of this hardware to 35 ft. lbs.

23. Reconnect the wiring and push the excess wiring through the hole into the pedestal. It may be helpful to shroud the wiring with split loom and tape.

24. Check the snugness of the 6 nuts and bolts around the center hole. The swivel should have firm, smooth resistance. These bolts should be snug but not overly tight. If resistance adjustments need to be made, use two 11mm wrenches, carefully inserting one into the hole to hold the bolt end.
