300E Front Seats Removal
 

Where are the bolts to remove the front seats on a 1987 300E ? I do not have a parts list and want to know if I need to look under the chassis for removal bolts, I need to patch some broken springs and worn stuffing, thanks to all in advance

There are 4 bolts, one at each corner of the tracks, which are accessed by moving the seat forward/back and lifting the carpet. Remember to unplug the seatbelt buzzer sensor wire.

There is also one (bolt) along the transmission hump behind a plastic piece that extends back (from the seatbelt I think).
There is a bundel of wires that comes from front floor area up under the seat whiich I have never disconnected so I'm not sure how easy that is (I think it might be zip-tied onto the seat frame and plugged into the various adjustment motors).

Edit: I hope your power seat adjustments are still working as moving the seat around greatly enhances access to the 4 bolts previously mentioned. There are also plastic pieces on the rear of the tracks that should be removed.

When I jury rigged my springs and patched my wires I left seat in the car and did not remove the wiring harness but used the power seat adjustment (once unbolted) to get it to stand up better (bottom faceing back) to gain access to parts.

P.S. Remove the back pannel of the seat, - there are 2 screws on the bottom of it - then there are rubber (seals?) that run the length of the pannel's sides (attached to the leather on the side of the seat). Work these seals off of the pannel from the bottom to the top by pulling out (to the back) and out (to the side) - to expose more of the inner workings (back support springs and headrest motor and mech.).

Bonus:
When you are inside the back pannel you can shore up a sagging cargo net by tieing the top strand in a knot about one inch over on one side and cutting off the excess, looks much nicer :D

Very simple job as outlined earlier, 4 bolts and the seat belt rail, all take 10MM and are easy in and out, makes it very easy to shampoo the carpet with no seats. thanks guys !
