rakesb Posted May 2, 2015 Report Posted May 2, 2015 The starter on my 1966 M20C is making a strange noise. I just read the lubrication guide (attached) and discovered that it calls for lubricating the starter drive with graphite & kerosene every 20 hours! How often are you lubricating your starter drive? With what lubricant(s)? What cleaning or other preparation work do you perform before lubricating the starter drive? Is it possible to clean and lubricate the starter drive without any disassembly? -- Bobby Rakes, (573) 337-3447, rakes_bobby@hotmail.com
RangerJim Posted May 2, 2015 Report Posted May 2, 2015 Upon the advice of my local A&P/IA, who is very experienced and competent, I give it a shot of Triflow every twenty or so starts. No starter problems in 500 hours/five years. Can't help you with the noise or disassembly questions. Good luck.
Piloto Posted May 3, 2015 Report Posted May 3, 2015 I have always used silicon lubricant in spray form with no problems for over 30 years. To clean the drive shaft I spray contact cleaner. After it evaporates I spray silicon lubricant. José
BKlott Posted May 3, 2015 Report Posted May 3, 2015 Whenever the cowling is off, I give mine a shot of silicon spray.
rakesb Posted May 10, 2015 Author Report Posted May 10, 2015 Thank you so much for your replies and advice. Flew twice last week without recurrence of the strange noise on startup. Have contact cleaner and silicone spray lubricant on hand, in case the noise returns. Will need to order some triflow. Please have a great safe week.
