Sterling if you want other seat parts man, please start a thread for those. This thread was intended to ASK someone to MAKE the GEAR THAT IS ALWAYS BROKEN

Mike Simard

Hey! I just realised my 87 has a broken gear too. I guess some sloppy po didn't do the preventative maintanance seat mechanism disassembly, Well fortunatly the gear broke just like it was designed to do!

Well...I've got an 1990 Acura Integra (basically Honda) that has 235,000 on it...original everything.....So far...bolster wear through on driverside...blower motor bad after water leaked into it from bad windshield install, and broken drivers side (inside) door release..bad ABS...everything else original..AC still works great too..
My 89GT has 297,000km (185,000 miles)..so far seats work fine..bolster wear drivers side...AC inop for a variety of reasons..Bad ABS...But like the Integra..Ive got manual sliders on the seats..

Later,
Tom

I pull up a lever and slide my seat forward / backwards. What is this "gear" you guys speak of?

heinrich

I bet your Acura doesn't sport the fancy fusible front gear that's designed to break the moment you try to manually adjust your seat. That's worht all the extra SRP right there

heinrich

Don't worry Hacker, my 996 sports slide in similar fashion, but the many other 928's I have ,,, sadly not.

I love my super light factory sport seats

His Acura didn't break because the preventative maintanance was performed!

Seriously, I did just notice a broken one on my car and my first thought was that there's a problem with the way that gear is held. It looks like a failure of it's 'bearing' surface that allows it to get out of alignment and jam. That appers to be the case but I'm not sure because I don't know how its supposed to be assembled.

My parents had a ‘91 civic with 600 000kms and another ’96 with 400 000kms. My buddy just sold his ’95 to another buddy with 320 000kms. Does that count? These are only 4 cylinder cars so that would make it 1 200 000km and 800 000km if compared to a V8.

The ’91 was bought in ’93 (12K kms). The car was not pampered at all. Driven every day hard. Maintenance was done when it needed. Went through 1 pair of axles, 1 rad, dozen set of tires maybe half a dozen set of breaks. Set of rear wheel bearings, ONE tb/wp change. The front rotors/rear drums were originals that were NEVER machined.

The 928s engines are very robust but a lot of other things around it aren’t.

The gear should not be designed to break. It should be designed tough enough so that it doesn't have to be a "fuse". At the same time, how much could a plastic gear cost? I'm sure its more from Porsche than it should be but I doubt that the gear is the only of its kind and only used on Porsche seats. There must be a source for these things other than Porsche.

Someone measure one and then go here http://www.rushgears.com/Tech_Tools/...p?fromHomePage

Ryan,
From 928 Specialists:
Seat Emergency Control Gear (on motor) 87-95: 928.521.818.03 cost $14.68
Seat Emergency Control Gear (with allen socket) 87-95: 928.521.818.04 cost $12.11

Guess you're screwed if you've got a 85 or 86 model.

Anytime something breaks on a Porsche we think it was designed to break. Heater hose rupture? Oh yes it was designed to leave you stranded!!! Anyway the gear is grbage. Similar to the odo gear. How cheap a replacement part is, makes no difference, because the NEW ONE will break the same way. And just when you need it to work. All that gearing up there, for what? If we put a steel gear there with no gap, I think we will not see any more broken teeth. I am a willing guinea pig

heinrich

Actually even with a new gear you are screwed. It will just break again.

If I understand this correctly, we're talking about a plastic gear that's used to manually move the seat if the power seat mechanism breaks down. Is that correct? I didn't even know my car had an "emergency" manual seat adjustment function. How many other cars have a manual seat position adjustment option if the power seat isn't working? Does the Acura have one? If not, it seems like if you want to make your 928 seat more like the Accura one, don't replace the plastic gear if it's broken, or remove the gear it if it's not. If you're that worried about your power seat becoming non-functional, and needing to make an "emergency" seat position adjustment before you're able to get the power seat repaired, maybe a steel gear is just what you're looking for. Maybe get two, so you have an emergency emergency manual seat position adjustment backup plan if your power seat ever stops working.

I think some of you guys are missing the point. I do agree that these gears could be stronger, but the fact is that they are there to move the seat in case there is an electrical failure.

Most people try to move the seat when there is an obstruction in the tracks and the motors are not even strong enough to do their jobs. In a case like that, even a metal gear will fail.

I think the first thing is to keep your tracks clean and clear of debris and to be careful not to drop anything down there.

I've been dismantling a lot of seats in recent months, and I see a lot more crap in the tracks than you could imagine.
