Land Cruiser Drivers Seat

 Decided to tackle the power seat gears on the drivers side today. I also have a clunk in the seat under acceleration and braking. Not a lot, just enough to be annoying. Did a search on IH8MUD and some folks pointed to the gears. I had ordered a full set from Gamiviti so figured I'd dig in and get it done.

First step was to wait for a break in the rain and yank the seat. Good opportunity to vacuum where the seat was.

On disassembly I find this little screw.

Somebody has serviced this chair before it appears. And low and behold, thank goodness I watched the Gamiviti youtube video and did the passenger seat first because whoever did the work forgot to put in the back washers. I might have missed that if I hadn't watched the video and done the other seat.

I grabbed one of the front washers and headed to the hardware store. An hour later I'm home and I find I made a small mistake. Yup, I forgot that the rear washer is slightly larger than the front washer. In fact, it's very precise to be able to fit over the splines but not over the main shaft in the back. I drilled out the washers I bought and installed it all and no more clunk. Going to be much better from here on out.

Land Cruiser Passenger Seat Gear

 When I bought the Land Cruiser, one of the things the previous owner was completely transparent about was the non functioning passenger seat motor that moves it forwards or backwards.  Apparently it's common for the gears in the seats to strip out over time.  Thankfully, Gamiviti offers replacement gears for a reasonable price.

First I had to remove the seat from the truck and tear it apart to get to the gears.  Thankfully the weather was splendid today to be out doing this kind of work.

Here is the bottom of the seat where all the work is being done.

Some of the parts that needed to be removed as well to get the job completed.

The gears on both sides were stripped out.  Here you can see one of the new gears pressed onto the shaft compared with the two old gears next to it.

One thing also that happens that contributes to the gear stripping out is the below end cap comes out and gets lost.  Gamiviti provides those as well.  The youtube video Gamiviti published to show how to do this job recommends drilling the piece and putting a set screw in to keep it from coming out again.  The screw cap was pretty loose so I followed the directions and installed the set screw as well.

Once back in the truck it works like new again.  I'm now able to move the seat forward and give Jakob some more legroom in the back.
