Yeah Racing Pinion Gear Super Hard Combo set (48P 33T-38T 6pcs #MG-48033-038)


For sale is a new in packet Yeah Racing brand 48 pitch pinion (motor) gear set to suit a huge number of 1:10th scale electric cars.Check your manual for compatibality (not suitable for all Tamiya or HPI E10). Over the years Tamiya have used at least 6 different pitch gears, so it is impossible for one size gear to fit all their cars, trucks and buggies. Make sure these gears are the correct pitch for your vehicle.

Description:

  • The motor gear series including 2 major types of Pitch Pinion - the 48 Pitch Pinion and the 64 Pitch Pinion. The 48 Pitch Pinion available from 15 teeth to 38 teeth. The 64 Pitch Pinion available from 17 teeth to 52 teeth. The Yeah Racing Aluminum Motor Gear are made by 7075 high quality aluminum with titanium coated surface.

  • Feature:

  • For: 1:10 EP, fit on 540 Motor
  • Material: 7075 Aluminum
  • Color: Titanium

  • Specification:

  • Pitch: 48
  • Teeth: 33~38

  • Include:

  • 48 Pitch Pinion 33 Teeth (1 Pc)
  • 48 Pitch Pinion 34 Teeth (1 Pc)
  • 48 Pitch Pinion 35 Teeth (1 Pc)
  • 48 Pitch Pinion 36 Teeth (1 Pc)
  • 48 Pitch Pinion 37 Teeth (1 Pc)
  • 48 Pitch Pinion 38 Teeth (1 Pc)
  • Set Screw (6 pcs)

  • How to calculate Final Gear Ratio?

    For example, if your car has the following setting:
  • Motor Gear: 25
  • Spur Gear: 84
  • Pulley: 19
  • Gear Differential: 38
  • Firstly, we need to calculate the 'Motor Gear to Spur Gear Ratio', divide 84 by 25 equal to 3.36. Then we need to calculate the 'Pulley to Gear Differential Ratio', divide 38 by 19 equal to 2. Finally, the 'Final Gear Ratio' is 3.36 x 2 = 6.72.

    Motor Turn used based on Final Gear Ratio:

  • 3.5T: 9.5-10
  • 4.0T: 8.9-9.5
  • 8.5T: 6.4-7.0
  • The above guideline is for reference only. The recommended motor turn may vary depending on different brands. More information can be found on motors' official websites.


    Review from RC Driver, Issue 108, December 2012

  • In electric RC, the pinion gear is meshed with the spur gear and provides power to drive train. A quality pinion gear will provide maximum transfer of speed and power to the motor.
  • I am a fan of precision manufactured, quality pinion gears that when properly meshed with a new or good spur are totally silent! These gears from Yeah Racing certainly fill the bill. By Chris Kovachevich, RC Driver Issue 108, December 2012
