Aircraft Starter Motor Replacement not required!

- It is not always necessary to replace your Lycoming engine starter just because its not staying engaged or is failing to engage the ring gear. A replacement of the Bendix could fix all your problems. Too often a very expensive starter motor replacement is completed when a much more cost effective repair could have been done instead.

Can not thank you enough for this video and sharing your knowledge. Not only did I save myself a lot of $$, but this was a fun project to knock out & we could have never done it without your help - and the production of this video. Thanks again - and all the best!
I am really glad you found it helpful. I agree it is a very rewarding repair to complete.
Any tips on removal of the starter? I've got a Penn Yan 172 with what looks exactly like the presto lite shown in the video. Bendix is actually stuck engaged to the fly wheel. Used to 'whir' occasionally but 90% of the time would work just fine. Went to fly the other day and upon startup the starter made an odd noise, came out to check and the gear is stuck engaged to flywheel. Prop spins fine but I can't get the bendix to return to disengaged position.

Thanks for the heads up
Your welcome.
HOLY CRAP!!! this is EXACTLY what happened to me. My (soon to be former) A&P was asked to take a look at the starter it was making this whirling sound.. one or two key turns then on the 3rd the starter would engage. Mechanic said "Oh the bolts needed to be snugged up a bit... it's fine now." The following week I took the plane out with the intent to fly locally not stopping the plane and it continued to do what it had been doing... third key turn starter engages and off I go. I then asked my (soon to be former) A&P to check out the ignition to make sure I didn't need a new ignition switch and Key. He checked this out and said it was fine, He cleaned it up a bit and it was fine. Foolishly I took the plane out and it did the same thing, one, two key turns and whirling.. third key turn, started engaged. Last Saturday, I took the plan out and flew to several cities around the state, it was a BEAUTIFUL day... how could I not fly. Each city it did the same thing. Finally, I was at my last stop for the day and the starter gave out. Now I am AOG. My (former) A&P said that I had to have a new starter. Never suggested a new Bendex. I was lucky, the starter was only 560. I think I am going to keep the old starter, order a new Bendex and replace it.... keeping one on my shelf at home. I will be replacing the starter at the away station. Talk about a logistic nightmare - trying to drive 2.5 hours there, fixing the starter, then driving home, getting the Bus to the city 20 miles away, then Uber to the city where the plane is, then flying the plane to a new IA for sign off -mean while I have to remove the upper and lower cowling again.. always a treat on my M20J... but, I'll have learned a VERY valuable lesson..... and gotten a new A&P.
I am very sorry to hear of your situation. I look after three Mooneys so I know how difficult it is to get at the starter.
This is a very common issue with many shops just changing the starter. I hope that you will find a use for your rebuilt starter and bendix at some point.
@@fastbackflying853 After getting th old starter out, there were additional screws missing. I'm going to turn this one in for the core charge. Rather this than sit on this not good part.
A couple of annuals ago I splurged on a Sky-Tec starter. The old starter really was shot. So was the ring gear, but that's another story.
Yes there are certainly times when it's more economical to get a new starter if there has been significant damage to it. Did you get a new ring gear install on your flywheel?
@@fastbackflying853 Yes, the ring gear was badly worn. Bad enough to strand me on a $100 hamburger flight (Mary's at CYYJ, a local favourite). The starter actually worked, but the ring gear was so badly worn it wouldn't engage. Shower of sparks, so no hand-propping. I improvised my way home and made some calls. :-(
I limped home with a new ring gear a week later. A couple of week later she was in for her annual and the shop called me "nice ring gear but your starter is on its last legs and you need to think seriously about a new one..." So I did.
Hmmmmm. I did that. Bought a sky tech for my Cherokee six when the bendix wasn’t engaging. Now I know.
Hey there, if you’re still out there, do you have the part number for a replacement Bendix? I have a Prestolite MZ4218 and I can’t find the replacement part number.
Great video, would love advice on how an owner/operator (non AP) can lube the bendix.
Every 50hrs the Bendix needs a spray with a high quality silicone lubricant.
Hey do you know where I can find a starter clutch for a o-200 continental on a C150. I’ve been looking everywhere!!
Yes I have a sprag clutch for the O-200. Where are you located? You should be able to get it from KADEX Aero Supply, Aircraft Spruce, or Niagara Air Parts.
What is your source for the replacement Bendix? I see you are in Canada (me too) and I always struggle for reasonably priced sources for aircraft equipment.
Thanks for the video, before I found it I was reading Lycomings comments about lack of service on the starters. I'm currently working on one that sat for 10 years and needs a little love.
Kadex can get these parts and Aircraft Spruce has had them in the past as well. It seems to be getting more difficult to get hold of them these days.
what is typical lifespan for a Prestolite MZ4206? I have a 1974 Cherokee 1266 TTSN w/ this Prestolite and the Bendix is sticking for the first 3 attempts, then it kicks in. Yes mine is old, but doesn't have much time in service and the starter sounds very healthy when it does engage.
I have seen them much older than yours. They are very tough and reliable thats one reason they weigh so much.
Obviously use or more correctly abuse will shorten the life span but I would very much think yours would be worth investing in a new Bendix drive.
log shows my bendix replaced in '87 (@857hrs.) and only has ~400 hrs. on it. Gear teeth look great as does flywheel teeth. Gonna try to clean it up and reinstall. Does the drive roll pin have to be replaced? assume yes, so where/how do you find one? @@fastbackflying853
I wish I could buy a bendix for my Lamar starter, unavailable anywhere.
Parts availability is becoming a serious problem! Oil filters, not available! This is crazy.
I have aircraft AA5 and has motor starter problem , when you try to start all I hear is wizz noise. If I was lubricant it what oil or spray I need to buy ?
Can I can lubricant without opening parts ? Is it easy ?
You would use a Silicon based lubricant on the starter Bendix. This is supposed to be completed ever 50hrs. Depending on the condition it may require removal for cleaning and a replacement of the entire bendix.
Thanks a lot, I bought XC professional lubricant for £3.89 from Ebay, went to airfield this Sunday to see my AA5 give little spray on bendix where I could reached. it has worked engine started. Thanks a lot . It was good help of your video. Much appreciated saved a lot of money.
@@mohammedkadir7223 really glad to have been able to help. I hope you get some good flying in soon. Where do you keep your AA5?
I keep at Wolverhampton airfield, and get my annual done wellesbourne airfield
@@mohammedkadir7223 I have an AA5 project for this winter. Fuel tanks and numerous airframe and flight control repairs to complete.
in the 80s the bendix was $40 US. 50 CAD for a spring roll pin, come on
I know it's an insane price for a roll pin! Needless to say it's a darn good thing one comes with a new bendix.
