Starter Adapter part# 635048A14
Hello,
Anyone know who apart from Niagara overhauls these adapters? These are the older sleeved adapters and Aircraft Specialty doesn't overhaul them anymore. Thanks, Allen

Canadian Aero - $2000 OH https://canadianaeromanufacturing.co...classic-style/
Quality Aircraft - $1495 https://www.qaa.com/products/aircraf...tarter-adapter Found an outfit in Hamburg Germany that claims to OH them as well. There may be others but I found these three rather easily. Best wishes. PS - There is an old wives tale that says not to run Camguard in Conti's because it will ruin the starter adapter. NO idea if there is any truth to it.

Hello ALL.
Are you sure your adapter needs rebuilding? I had to rebuild mine but I only purchased the bearing kit from Niagara, which was about $150 vs $1500-2000! Regards, BILLS 65 C337/owner pilot and A&P

starter drive adapter
Allen,
We just had one rebuilt at Aircraft Accessories in Tulsa. It was $450 in labor, flat fee I suppose, and we needed $500 in pieces and parts. Bearings, springs and seals. We had it overhauled in November of 2021. They weren't fast, but they got it done. Steve

The problem with cam guard and synthetic blend oils are that if you run straight weight for a long time and then switch to adding cam guard or switch to synthetic blends the problem starts. But if you run them from new with synthetic blend and or with cam guard the adapter should last a long time. I have ordered some parts and we shall see how it goes and will report back. Thanks everyone with your responses.

Aircraft specialties
Its interesting how fast people will stop working on things. The original post noted that Aircraft Specialties doest rebuild this unit any more. I had mine (same part number) rebuilt by them May of 2021, so less than a year ago. I sent it to them on Wednesday and by the following friday I had it back.
Its a bummer to lose support from good shops.

After disassembly and thorough cleaning the measurements revealed that the shaft drum, the drive gear shank's steps and also the friction sleeve are all still within the standard tolerances. This is lucky since no machining required. The only worn item was the spring. One was ordered from Niagara which arrived in 3 days. Installation is a precise procedure and the TCM manual has to be followed precisely as well. In addition, to be extra careful, the spring was heated by a heat gun and the drive gear frozen in the freezer to make an easier spring installation. After that, the friction sleeve was heated again with the heat gun and the combination drive gear and the attached spring unit was cooled in the freezer. This insured an easier fit of the spring in the friction sleeve.. After this the T drive accessory was thoroughly cleaned and lubricated and assembled per TCM. The assembly was then installed with new gaskets and safetied, the starter then reinstalled. After installation tests revealed a perfect start every time without slippage. Here is a PDF from Aircraft Specialties. Hope this helps. https://www.aircraftspecialties.aero...sembly_Aid.pdf
