Cable and stub shafts

[Wally Marsh]

Marty,

Save your worn out 3.5 and 7.5 K&B prop shafts, it’s easy-peasy to replace the lead-teflon bushings with some simple tooling. I did this routinely back in my K&B days, but as has been said they won’t last too long - and the bushings are relatively inexpensive, Gary normally carries them (Octura brand).

I get my bushings from McMaster Carr, they last longer than the lead Teflon, but not by much.

Thanks guys  Wallster maybe Mendota ? or if you come over ?

OSE sells some lower units and parts. Here is a OS clone I believe.

Mark,

What prop shaft assembly are they using and does it hold up like the O/S?

 

[Carl Van Houten]

Carl,

I'm using the stock shaft that comes with the stock K & B unit. I replace the teflon bushings in the housing with a precision machined, shoulder type, Barium metal bushing which is pressed in. The drive dog rides against the teflon washer & the shoulder type bushing. The stuffing tube is a hard brass tubing with a grease fitting. No wear or failure problems of any kind!

Jim, Where are you buying your bushings?

I don't know as I only have an old Hyperformance lower that I run. Maybe Mic H. can help here.

Carl,

I didn't by the bushings. I machined them from Bearium (B-8 grade) solid stock. The bushing protrudes out some on the front side & it is a "snug fit" in the stock K & B housing, with a shoulder on the back side. The drive dog is a hardened piece that rides against the teflon washer.The standard K & B prop shaft is a slip fit in the bushing. Bearium metal is a non-seizing, non scoring, long wearing, self lubricating, low coefficient of friction, high shock load, high compressive strength, rough cast cored or solid bar material available in 13 inch lengths. The bushings service life as well as the stock shaft appears to be indefinite!

Great info! Looks like you have it sorted Jim. If you ever have 1 or 2 you would part with please let me know.

Jim, any clue as to what alloy or the properties are with the OS prop shaft bushing? 

Do you have a supplier you recommend for the Bearium? I can find plenty of info on it, except where to buy it.

I have no idea what is being used by any of the manufacturers for prop shafts or bushings. The two original developers of the Bearium alloys sold the company to Metal Tek International. All of the original alloys are still being made with even greater applications being found in the bearing industry. The person to contact is Denise Kline; 262-544-7813. When I purchased the B-8 alloy in 1984 the price was $4.50/ lb. I have no idea what the present day price would be.
