I've recently rebuild an alternator from 9-5, here are the prices:
Front bearing Bosch F00M990410 $7,80
Rear bearing Bosch F00M990405 $7,00
Rear bearing housing* $1,00 (it's plastic and breaks)
Regulator Bosch F00M144169 $28,00
Regulator brushes IKA 010651* ** $2,50
Slip rings IKA 120390* $3,10
Pulley with clutch Bosch F00M991289 $48,00 (this was cheap for Bosch, ~50% of standard price).
* replacement part with similar quality
** only if you want to just replace the brushes keeping the old regulator
Yet Another Educational Part ;)
Most 9-5 alternators do not have a clutch, as it was introduced from MY06. You can put one or not if you do not want to. Clutch prolongs belt life about twice and reduces vibrations, but alternator will work fine without it.
Basic parts needed for rebuild of a healthy alternator (just wearing parts, no damage to rotor, stator, rectifier etc.):
Brushes replacement + bearings + slip rings = ~$21
New Bosch regulator + bearings + slip rings = ~$46
Above + Bosch clutch = ~$150
As you can see only the OEM clutch is pricey (made in Canada). You can buy cheaper replacement like AFP0060 for about $26 - I do not have a clue how long it will last, but it easy replaceable on the car).
Job requires:
- PZ screwdrivers
- a few hex sockets
- impact gun to remove pulley*
- bearing puller to remove bearings from shafts
- glue for bearings like Loctite 603), as the front bearing sits loosely on a shaft so the internal bearing race have to be glued to the shaft to ensure proper operation (no slipping).
- oven to heat up front housing**
- soldering iron for slip rings installation
- threaded rod with bushings for removing the front bearing from the housing
- assembly grease without cooper (like Molykote P-74). Cooper and aluminum have different electronegativity what causes electrolytic corrosion). Preferably use grease without any metallic particles, Mo2S additive works fine. Grease enables easy bearing insertion, prevents seizing and corrosion.
- hammer and a wooden block will be also useful (removing front bearing could a pain...)
- Melissa officinalis tea for nervous beginners ;)
* If you have a clutch then you will need two special tools - one for removing (31 teeth spline) and the second for installation (combined spline/torx tool to keep the shaft from spinning while tightening the pulley). There is no option for removing the clutch or standard pulley without impact gun, as there is no place to securely keep the rotor from spinning.
** Oven enables easy front bearing installation - after heating the aluminum housing up to about 100°C (212°F) you can insert bearing with your fingers. This is a perfect method for installation bearings in parts that could be heated up easy (like intermediate shaft bracket) - no force, no tools, no damage to the bearing possible. This could be used also for installation of bearings on shafts - in this case heat up the bearing itself. This a a very satisfying feeling when you insert a new bearing with fingers remembering the battle to remove the old one. It's definitely good psychotherapy, nevertheless be smart to keep your good mood even longer - do do not show it to your wife as a success - answer "so what?" will ruin your pride ;)
I really recommend to buy an used alternator, rebuild it carefully and then swap it. Rebuild could take long time, especially when it happens that you will need more parts as you thought.
If you do not have any mechanical skills or tools, especially tools then skip it -> buy a rebuild alternator.
