About five years ago Performance Specialties ( http://www.pspec.com/default.asp ) sold true ABC liner and piston sets for OS 61SF ABC-P and OS 61RF ABC-P engines. I contacted them to see if they would be willing to manufacture them again and they are interested. As you may know OS has discontinued the liner sets for the SF. They would need an order of 50 units that could be a mix of SF and RF parts. The selling price will be $90 with a 50% deposit and 50% on shipment . It would take about 90 days to gear up for production. I have extra liner sets in my spare parts kit but it would be nice to have some Performance Specialties liner sets too. I think I’d order two sets. Is anyone else interested in trying to get an order together?

Would they have that available for FSR 61 ABC as well, or be able making it available ?
In that case I would be interested.
Further, I have a OS 61SF, could maybe use a spare as well, and tell that company never to stop produce such things !

Best regards,

Steven

I would think they might do FSRs too but that would need to be a separate deal.

Could you ask about that ? I guess a lot of other people have such a nice engine lying around, having the same problem

They said that the FSR liner is a different size so it would require a separate 50 quantity order.

I'd definitely be interested. I need a new piston/liner for a .61RF.

Tim

quantity 50 ??? I guess we should open a new treath then for this item . I could take two

I would take 3 FSR liners.

I need one for a hanno special. If they can do it count me in. m.g.

Would they consider the Hanno Special liners as the same? Bore and stroke are the same as the earlier long-stroke version, but they have the additional exhaust port notches.
I'd take a couple of Hanno piston/sleeve combos. I had three OS .61RF ABC-Ps with PS piston/sleeves. Lots more power and incredible durability compared to stock OS. Wish I'd kept them[]

We can do the Hanno along with the SF/RF. The ID and OD of the sleeves is the same as are the pistons. It is likely that we will not do these in ABC, but in AAC. Aside from them being lighter in AAC, we have found them to be more durable than ABC, so you get a better product.

Are rods still available thru Tower/Hobbico/etc? It is always advisable to change the rod when you install a new P/C in an engine. If rods are an issue, I suppose we can make them too.

Looks like we are getting some interest on this. Keep beating the bushes so we can get an order together.

Hi,

Count me in for the following:

2 x Liner and Piston assembly for the O.S MAX .61 SF ABC-P.
3 x Liner and Piston asembly for the O.S. MAX 61 RF ABC "HANNO SPECIAL".

Delivery to Stockholm, Sweden where I live should not be a problem I guess.

With kind regards,
Gunnar

I want to add that these parts will be of the highest quality. The quality level of parts will be like what you would see in the high end engines like the Nelson engines.

Hi Dave,

Please count me in:

* 2 sets -- OS Hanno Special ABC (Mk I)
* 2 sets -- OS 61RF-P ABC

Thanks !!!
Frank

Wow, since we seem to be placing orders I'd like the following:
3 sets Hanno special piston/sleeve
1 set OS 61RF (pre-hanno) piston sleeve

I assume the orders will actually go through Performance Specialities and this is just to make sure we'll have enough orders for Dave to produce a run of piston/sleeves.
A BIG THANKS to DAVE SHADEL for helping keep our 60s going!!

Dave S, not exactly BPA related but will the OS 140RX AAC piston/liner assemblies be available again ?? TIA....Ed M.

Yes, the OS 140 will be available again. Hopefully within 60 days.

Thanks, Dave

Dave, I've been following this thread wondering if doing the same thing ref YS 60s is a possibility. I've done a few web searches looking for YS 60 pistons/liners with no success so I'm guessing there might be a market for those as well. What do you think?
