NotarPilot Posted June 14, 2019 Report Share Posted June 14, 2019 I’ve been having an ongoing issue with my Sky-Tec149-12LS starter not always engaging. Sometimes it’ll just make a clicking sound when I engage the key then it’ll crank on subsequent attempts. Anyways, to make a long story short, my mechanic and I thought perhaps switching brands would help so I bought a B&C starter which would not fit. I called B&C and was basically told “Yeah, sorry but we’re aware our starters don’t fit Mooneys” as they make contact with the fuel servo. So the other option was to switch to an overhauled Prestolite (Which apparently are no longer made new anymore) or stick with Sky-tec. I opted to stick with Sky-Tec. Sky-tec has been pretty good with their customer service and even told me to send it back even past warranty. The guy I spoke with on the phone suggested maybe switching to a 149-12NL if it’ll fit. Does anyone know if the NL will fit on a IO-360A3B6D? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
ArtVandelay Posted June 14, 2019 Report Share Posted June 14, 2019 I have 149-NL on my J, but my engine is a A3B6, so YMMV.Tom Quote Link to comment Share on other sites More sharing options...

OR75 Posted June 14, 2019 Report Share Posted June 14, 2019 I have a skytec 149-12NL on my IO-360-A3B6D and it fits perfectly installation is straightforward although it takes some time to remove the old starter and install the new I replaced a Prestolite that was still working to: loose a few pounds (i think about 10 lbs) faster spinning I kept my prestolite as a spare 1 Quote Link to comment Share on other sites More sharing options...
carusoam Posted June 14, 2019 Report Share Posted June 14, 2019 Want to focus on what isn’t working? What is keeping the existing starter from engaging? Or, you have already made the call to abandon ship, no going back... The Bendix drive is the primary culprit of starters not engaging... The BD is so mechanically simple a good clean and lube gets them working again. My O360 used to suffer between annuals... So a quick clean and lube would usually work for a few more months... The sign of need... whirring of the starter, no engagement... PP thoughts only, not a mechanic. Best regards, -a- 1 Quote Link to comment Share on other sites More sharing options...
Tommy Posted June 14, 2019 Report Share Posted June 14, 2019 Yes it is a drop replacement on a J and it's good for both 14-28v. You might need to loosen up the FCU in order to get the old starter out. It takes about 5 hours to get it done. It sounds very different - and , in my opinion, more "modern" sound if there is such a thing - when you crank. Weigh much less. Works well. 1 Quote Link to comment Share on other sites More sharing options...

I’m in the midst of getting my commercial, CFI and CFII add-ons right now and wanted to be done in a few weeks. What is keeping the existing starter from engaging? I believe it was the starter solenoid from the last repair under warranty. It was working fine for a few months until the problem started again.

I’m going to give the NL a try and see what happens. 1 Quote Link to comment Share on other sites More sharing options...
Andy95W Posted June 15, 2019 Report Share Posted June 15, 2019 How old is your starter relay? The 'click' but no engagement could be the relay clicking but still not making contact to pass current to the starter. Quote Link to comment Share on other sites More sharing options...

If your starter whirrs but doesn’t engage, it’s time to install a new Bendix drive in the starter, or install a new Sky Tec starter.

ArtVandelay Posted June 23, 2019 Report Share Posted June 23, 2019 What’s the preferred method for cleaning? Mine whirrrrs sometimes. I tried brake cleaner and then silicone spray...it’s a short term solution...if you need dependability...follow Clarence advice. Tom Quote Link to comment Share on other sites More sharing options...
201Steve Posted June 24, 2019 Report Share Posted June 24, 2019 @M20Doc is the drive something you can change in the field or Send off? Any idea of approx cost? Ball park Quote Link to comment Share on other sites More sharing options...

Ball park This is a field job, no need to send it away. Once you know the model of your starter, you can figure out the part number of the Bendix drive, likely an EBB-131. With the starter removed from the engine, pull the nose case off, extend the Bendix, drive out the roll pin and remove the Bendix. Reverse to reassemble. You can disassemble clean and lubricate the Bendix, but at around $100 it’s hardly worth it. Clarence Quote Link to comment Share on other sites More sharing options...
NotarPilot Posted June 29, 2019 Author Report Share Posted June 29, 2019 Hartzell has been great in terms of cust service so far. They allowed me to ship back my LS starter several months past warranty and sent me an NL starter at no charge. They even shipped it back overnight for me since I was AOG. The guy I spoke with at Hartzell said the solenoids are a point of failure on the LS and that the NL version is a bit better. I just got the replacement installed today but I'm going to change the oil while it's down since it's due. I'll report in the future if this starter holds up. My A&P said the new starter is working great when he tested it though. Quote Link to comment Share on other sites More sharing options...
NotarPilot Posted July 12, 2019 Author Report Share Posted July 12, 2019 So far the starter is working out well. I’m really liking the 149 NL. I highly recommend it. It’s got great cranking power. Quote Link to comment Share on other sites More sharing options...
