Starter motor pinion gears of the DT® Spare Parts brand are made of hardened special steel with high surface quality. The chamfered tooth flanks of the pinion gear ensure perfect meshing in the flywheel.
Damage to the pinion gear and the flywheel are thus avoided and the power of the starter motor can be optimally transmitted.
The ball bearing housings are manufactured in an aluminium diecasting process. They contain high-quality ball bearings, sealed on both sides, to enable perfect functioning of the starter motor. By the use of highquality shaft seal rings, the internal parts are well protected against moisture penetration. The rear housing also contains a ground/earth connection and a condensation drain hose for ventilation.
Only highly-resilient pinion gears are used for planetary gears of the DT® Spare Parts brand, thus ensuring long-term functioning of the starter motor.
The magnetic switches have connection threads made of copper, which provide very low contact resistance. Due to the low resistance, a loss-free power transmission is made possible and heating up of the contact points avoided.
The starter motor carbon in the carbon-brush holders are manufactured from special carbon and enable a long service life, even with frequent start-up operations. In the carbon-brush holder there is also an over-temperature sensor, which switches off the starter motor during continuous starting, and thus protects against overheating.
In addition to starter motors, the complete range of the DT® Spare Parts brand offers all other spare parts for engines.
