Replacement Stepper Gears - Specifications

 

What's so special about our precision replacement gears? With specialist advice we designed the following combination: the smallest gear has bronze outer and mild steel inner teeth, the same for the middle gear, and the larger (which takes most of the pulsing, wearing constantly on the same 3-4 teeth) has bronze outer and hardened steel inner teeth. Durability is where it is needed most.

These gears are not mass produced, but precision-made in small lots by a specialist workshop, so considerable skilled workmanship is involved. However, due to lower manufacturing costs in Australia and currency exchange rates we are able to offer them at a competitive price. These gears cost less than a new stepper assembly from Alfa and even the new one, we understand, still has nylon (plastic) gears inside. (Nylon, by the way, runs smoother and quieter, and is fine for fast-spinning applications, but in this pulsing/shunting application nylon teeth wear quickly and break).

Don't do the job again next year. There is a considerable time and cost in accessing the gearboxes behind the dash and removing/replacing each assembly. Why spend this effort or money only to replace the cause of most problems (the plastic gears) with another similar set?

In summary, we believe these miniature gears, manufactured to demanding quality standards, are far superior to the original parts they replace.

164 owners (including us!) have needed a long-lasting fix for this problem: and that's what we have set out to achieve with these replacement parts.

 
Features:

• High-grade bronze, mild steel/hardened steel for long service life.
• Precision-cut for smooth and precise operation.
• Suitable for both left-hand-drive and right-hand-drive 164's.
• A cost-effective solution.
• Materials and workmanship fully guaranteed
• Manufactured to international standard ISO9002:1994
• Proudly precision-made in Australia.
  Contents (full set):
• Replacement gears (6) to overhaul two stepper motor gearboxes.
• Shaft "speed" clip for the air temperature gearbox shaft
• Assembly instructions

Note- A full set is required to overhaul both the steppers found behind the dash in the 164, however if you want to recondition only one stepper gearbox we also offer a 'half set':

• Replacement gears (3) to overhaul one stepper motor gearbox.
• Shaft "speed" clip for the air temperature gearbox shaft
• Assembly instructions

The air distribution drum reinforcing ring (highly recommended) is available at a small additional cost.
