Hi all. I?m starting my fifth annual a couple of weeks early because my starter is crapping out. I have a Sky-Tec 149-12LS. As is usual with starters, the solenoid attached to the starter housing is the culprit. I really hate to pay several hundred dollars for a new starter when all I need is the solenoid. Anybody got any idea where I can get a replacement? My second question involves the brakes. Since I?m installing new shoes, I just as well change the O-rings. Last summer, I toasted an O-ring taxing all the way around to the Northwest corner camping area at Oshkosh. The EAA emergency maintenance folks kindly gave me the correct replacement, whatever size that was. But I?d MUCH rather change it in my hanger that on the grass at OSH. Anybody know the size of that O-ring that goes in the standard Van?s Cleveland 500/5 wheel/brake assembly? Thanks.

Several years ago, I got a replacement solenoid for my starter from the starter manufacturer.

They do not like selling parts for you to replace and would rather have you send the starter to them to have repaired. Talk nicely to them and tell them you can do it yourself if they provide the part.

The parts list for the Cleveland 30-9 brake that is used on my RV can be found at: http://www.rvdar.com/Brakes/30-9_Parts_list_.pdf

The O-Ring is find # 3 and is a MS28775-218.

I just looked up the O-ring up yesterday for another RV'er.

It's no secrect that Mil 5606 is not very good stuff. As it turns out the Cleveland piston seal for the 30-9 caliper is an ordinary MS28775-218 nitrile o-ring. Nitrile's temperature rating is - 65F to +275 F. A caliper seal with a 275F temp limit is below automotive standards, but that's another story. Changing your caliper seals to Viton seals might be a good idea because Cleaveland uses ordinary nitrile seals. If you have Robby Grove brake calipers it would not surprise me if he used the higher temerature Viton seals during their manufacture.

Cleveland specifies that either Mil-H-5606 or Mil-H-83282 as acceptable. Mil-H-83282 was created because the military was tired of setting it's airplanes on fire. Mil-H-5606 is the standard red hydraulic fluid sold by Spruce, Wicks, Chief, etc.

It is a petroleum base, and it has a very low flash point. The Mil-H-83282 is also red, and compatible with 5606 fluid as well as seals created for 5606. However, it is a synthetic, with much higher flash and burn points, and is self-extinguishing when removed from the ignition source.

You can download complete specs for Aeroshell Fluid 41 (Mil-H-5606) and Aeroshell Fluid 31 (Mil-H-83282) at:

I swapped my brakes over last summer--it only took an hour or so to do both sides with viton O-rings and 83282 fluid

I have a spare solenoid in my tool bag that I bought directly from Sky-Tec. Just call 'em and ask to purchase a solenoid as a spare. They should be able to help you out.

FWIW I haven't needed the spare since I started carrying it over 1000 hours ago. It's my good luck charm.
