My driver seat adjuster has a problem. The up/down seat actuator for the front of the seat has failed. I can hear
the motor run when I try to raise of lower the seat front but no movement. The rear actuator is working OK.

So I took the actuator out and disassembled it. The plastic gear has some teeth missing ans had split in half.
I see that some guy in Turkey is selling replacement gears. It looks like the correct part.
Has anyone used his parts with good results?

Replacement gear on eBay.

This is what it looks like.

 

I sell Jeep seat motor shafts (with plastic gears) on ebay. Jeeps Grand Cherokee and Chevy Impala have same problem. The reason is not a weak gear, reason is rusty seat axles. Nobody greases them. Make sure your get axle free before trying new plastic gear, use synthetic motor oil. good luck.

 

or you could go for brass cog replacement; X Type seat mechanicals identical to Mondeo gear.

or from China:
Mondeo Seat adjustment gear - Hong Mei Trading Co., Ltd

 

jagger: I replaced the up / down gears on both front seats of my 2002 X-Type. The nylon teeth strip when people adjust the seat too far until it abruptly stops at the min or max height, the teeth yield and the motor continues to spin.

For the 1st repair I installed a brass replacement gear. For the 2nd repair I bought a used motor for dr dome - member of this forum who parts out X-Types. Why? Because the most difficult step to install the new brass gear (and I presume a new nylon gear) is drilling a hole thru the hardened steel shaft so you can secure the gear in position with a sleeve pin. I used a hand drill and found it more challenging than anticipated. If I had to install another brass or nylon gear, I'd use a friend's drill press to drill the hole thru the steel shaft.

 

Apparently, a 2005 Winnebago Adventurer has an after market brass gear kit that fits the Jaguar X Type.

I bought the gear from the guy in Turkey on ebay. The gear is good quality but will not fit
without some significant work.

This is what the shaft looks like with the broken gear removed. The original gear
is threaded internally and held on by the knurling on the shaft.
The new has a smooth hole smaller than the thread. To fit the new gear to the
shaft I had to turn the shaft down on my lathe.

The new gear is held onto the shaft with a roll pin. They include the proper size
drill to drill the hole for the roll pin. The roll pin hole in the gear is not accurately
drilled, it is off center.


I used my milling machine to align the drill with the hole in the new gear.
I pressed the roll pin in with no problem.

Here is the motor reassembled. I put the seat back together and everything works OK.

Knowing what I know now, I would have bought the gear and shaft assembly for $10 more.
Unless you are as well equipped as I am, this job cannot be done with the tools that most people
have. It would have been a 2 hour job rather than the full day that it took me.

Hope this helps,
Pete.

 

Is it possible to just set gears for lowest position and just leave there. Mine is stuck in the highest position Taller passengers have hard time getting in and out
