Comparison of "light-weight" starters with original starters

I've received a lot of feedback (and warranties) on light weight starters over the past several years. Here are some of the trade-offs between a light-weight starter and a traditional starter.

Durability Light weight starters are not as robust or durable. We have an extreme operator who makes up to 20 starts per airplane per day. Lightweights do not last in this high use environment

Light weight starters (especially 12 volts) consume can not be cranked for long period of time like the traditional starters. The massive amounts of current consumed by these starters cause the starter to overheat very quickly. Flight Schools have had to instruct their instructors to teach students to limit starter engagement times and allow starter cool-down times between attempted starts.

12 volt light weight starters will not crank the engine if the battery cables are in poor condition. The current demand is too high. You may have to change out the battery cables especially if they are the older aluminum style and you have a battery in the tail of the aircraft.

Some starters (not the Electrosystems) require cowling or bracket modifications to install. Installation time may be more than you anticipate

Other than that those little starters sure don't weight very much and I'm sure that when we all get used to operating them that is all we will see on aircraft.

What is the proper lubricant for the starter Bendix (engagement gear on Lycoming engines)

Prestolite or Electrosystems starters use a Bendix gear that rides on a shaft. It is important to keep the shaft clean to prevent sticking. Electrosystems and Prestolite recommend a dry silicone lubricant as wet lubricants attracts dust and dirt.
 

Did you know that the Bendix drive was invented by Vincent Bendix and first used on the Chevrolet "Baby Grand" in 1914.
