Issues with the motors can arise that are not addressed by Rodney's kit I found. The kit is fine but it may not be that simple. In my case, the drive hub was slipping on the output shaft. I am not alone in this experience I am told. I drilled through the hub and the shaft and inserted the end of the drill bit with JB weld as a shear pin. Works fine so far. Been a few months now.
Hello everyone! This guy is great and has done numerous video's on fixing Fiero problems, especially Head light Motors. Go to this U-Tube video http://www.youtube.com/watc...re=player_detailpage and watch. After viewing his video you may feel confident enough to do it yourself! I myself do rebuild them if you don't feel comfortable enough to try it yourself, feel free to contact me from PFF
Totally depends on if we are talking gen 1 or gen 2.
The gen 2 rebuild is so simple I could do it on the side of the road at night in the rain. Or do it over my lunch hour and still have time for lunch.
The gen 1 rebuild is a major pain in the you know what and I wouldn't even try it.
I've done both - replace the gear in Gen 1 & the three cylinders in Gen 2. Seemed like a similar amount of work... What Gen 1 issue are you concerned about?
I have offered Generation 1 rebuild services for about 5 years. Generally speaking, they are more difficult than the Generation 2, simply due to the different part that fails in the respective motors and they way they are designed.
The first part of the Generation 1 motor to fail is usually the shock absorber 'bump stops'. Once those fail, all the motor torque is exerted onto the hard plastic gear. Since the gear always torques up on the same teeth at the end of either direction of travel, they eventually sheer and the motor will continue to run on once the headlight door is either opened or closed.
The bump stops and gear are held in place by a drive plate that is press-fit onto the gear shaft. Removal of the drive plate is necessary to replace the gear and bump stops. Separating the plate and shaft destroys this press fit. Even though the plate can be put back onto the shaft in what might appear to be a good fit, it isn't as secure as it was when you removed it. It is prone to failure and separation at some point.
For that reason, I invested the time and money to design and have tooling made that mates the shaft and drive plate back as they were from the factory. It generally takes about 3 hours for me to rebuild a Generation 1 motor, start to finish. I could do a Generation 2 motor while eating dinner.
We're often advised to convert to the Generation 2 motor system, but there's just not enough out there to convert every Generation 1 system, so we must rebuild the Generation 1 systems as long as we can find parts. The other part prone to failure is the limiter switch-brush assembly. The Fiero Store was working on having those reproduced. My efforts to have brushes reattached proved to be too costly for the number of units I encounter so I abandoned that aspect of rebuilds.
