The International Cessna^® 170 Association

There are 2 garloc type seals in the C-145-2 / 0-300-A starter.

One on the sliding gear shaft, and one on the motor shaft. does any one know the generic part numbers?

Tom, my 170 & continental parts books are at the hangar, so I can't look it up now. But I know I've posted that information before, at least the Chicago Rawhide/Napa p/n for the starter clutch (pinion) seal. I may have posted the p/n for the motor shaft seal also. Did you try a search? I'll try to remember to get the p/n's the next time I'm at the hangar.
If you measure the ID/OD/ thickness of the seal, the Napa guy can look up the seal number in a reference book the countermen have.

Tom,

Some numbers I have gleaned from past forum posts. I have not researched these but filed them away for future use. I have a similar pull-start on my Cessna 140.

Chicago Rawhide seal CR9859 clutch drive seal

National Seal # 6324-S

The armature shaft seal is a regular "garlock" type seal (CR 7512)

The Genuine Delco-Remy parts are:

The PN for the Clutch shaft is: 1910379
The PN for the motor shaft is: 1867150 (armature shaft seal)

They are both available from El Reno for $14.50 each. 800-521-0333

I have a continental book too, and when you order from El Reno, or comtinental, you get CR seals.

Take the damn seals to the NAPA store, lay them on the counter and say "Gimmie two of these, Please."
They sure as hell wont be any $14.00. And they are made by Chicago Rawhide!

Tom, I found the starter-clutch seal info somewhere else here at home, it's Chicago Rawhide (& Napa) p/n 9859. I believe that CR makes them for Napa. The Napa price was $4 about a year ago.
Some 170's use a slightly thicker or thinner seal. I can't recall which one mine is, but I think it's the thin one. The other seal is (I think) p/n 9858. I think some early starters came from Continental fitted with only a rawhide washer, & were later machined for a proper oil seal. That might account for the difference in depth of the oil seal cavities.

My Customer has elected to go with a new SkyTech starter.

Thanks for the help..

Does the Skytec starter require the removal of the pinion shaft?
Tom, after the dust settles, I'd be interested in finding out about the costs & labor involved in converting to the Skytec. I would guess that some of the other folks here would also. Thanks in advance.

Eric

I'd be willing to bet that the manufacturer (any manufacturer) is gonna tend to describe the installation of their product as "quick and easy", instead of "difficult & a pain in the butt", which might be closer to the truth. A recap of the job & the costs involved, by someone who's just done it, might be more accurate fom our (the consumer's) point of view.
But I will admit that I haven't (yet) looked at Skytec's website, they might make a liar outa me.

I Have Ken's engine my shop for overhaul, and have the shaft in my hand, putting it in the lathe and removing part of it is easy.

But they now have a starter kit that does not require modifying the engine.

My new Spruce catalog lists the SkyTec p/n KCST2 at $563. This consists of a model C12ST/2 starter & the kit to convert from pull start (starter button,wiring, & STC). Seems like a pretty reasonable price, the comparable stuff from B&C lists for about $870!
It's still cheaper to exchange your stock starter ($230) & starter clutch ($155) though.
Anyone here running the SkyTec or B&C starter? How do you like it?

I bought a Sky Tec starter for my IO-360 when I converted it a couple of years ago. This is a totally different starter than is used on the 300 inch engine, but there was a serious fault in the design of the starter gear train and it caused the starter drive to wear excessively. That has now supposedly been corrected, but they want $150 for the fix. My point is, make sure this starter has been well proven before investing any serious money in it. I believe this starter for the pull start 300s is a relatively new item.
If anyone has any questions about the problem I had, I'd be glad to talk to them about it. My phone number ia 916 635 5566.

The pull starters seem to work just fine. In my opinion, the starter "upgrades" are a solution in search of a problem. If it ain't broke, don't fix it. The one improvement might be lighter weight.
Talking to people about the SkyTec and similar Lycoming starters, I've heard it said that they turn the engine over so fast the impulse coupling can't do it's job. I've never had starting trouble with the old Delco pull-type starter, provided the starter, starter clutch, battery, and electrical cables were all in good shape. Like I pointed out, it's cheaper to exchange the stock starter & starter clutch than it is to buy the fancy stuff.
BL makes a good suggestion -- wait until the fancy new-fangled stuff has a well-proven track record before spending your hard-earned money on it.
