    Joey and all -
     
    What are some of the digital alternatives over the old need/gray wire setups?
     
    The OP brings up a good question. How long can a 582 be stored after an overhaul with respect to seal life?  I'm preparing to run mine. It was overhauled and pickeled 10-yrs ago. After I hung it, I serviced the G/B. Since then the oil has been leaking out of the lower weep hole. I'm hoping after it's running that particular seal will set.  Makes me wonder if this gray head will have to be pulled apart again to replace the engine seals?  I have had luck in the past rejuvanting seals by adding DOT brake fluid to rejuvante them.
     
    In the meanwhile, I'm discarding the worry beads and planning to proceed w break'in and see what happens. That'll be a few weeks as I wrap up the coolant and electrical connections.

    Jim,
         Guess you didn't find a part number and brand on the bearing?

    Well, I finally got some more accurate dimentions for the Kitfox hubs.  I made a drawing showing them, plus a couple of pics showing the hubs themselves.  These are hubs that came with a Kitfox 3 originally,  Hope this answers most of the questions.  Bearings and seal outside diameter is 1 9/16", the bearing race is 1/2" wide.  Jim Chuk

  4. Trackwelder added a post in a topic Wanted a Rotax C redrive   

    Rotax has a 90 hp 2 cylinder 4 stroke that weighs only 119 lbs, I took a look and could not find the price for an engine, but the price of a jet ski with a closed loop cooling system was under $5000 but it does not have the hours in the air of the Yamaha.
         I am not done but I have my engine, 2 people are building adapters for the engine to a redrive and all I am waiting for is money, I spent some of it on a lathe, but I am hoping to make a few dollars with some little pieces that people are wanting.

    BRS 5 1200 for sale
    I recently acquired a 1200 lb canister BRS.  It is out of date, so it should be repacked.  I have the bridles that were supplied with it for a Kitfox 4.  The two attachment straps hook around the front wing attach points, so it should work on any Kitfox or Avid.  I can send it to BRS for repack, and then they can send it to you.  Price to repack with new rocket is $1500.  Price of new 1050 BRS is $4650, and for the 1300 is $6800.  They don't currently make a 1200 model.  I have to get $1750 for mine, add $1500 for the repack, and you are at about 1/2 or 2/3 the price of a new one that is as good as new with a repack.  If something is wrong with the chute, and BRS wont repack it, the deal is off and you just pay the shipping from me to them.  About 200 miles distance.  Anyone interested?  Thanks,  Jim Chuk

    Different bearing diameters.  I will try to pull one off today and get some better dimentions on the newer Kitfox hubs.  Jim Chuk

    The lathe I have ordered will swing the par, If you have a reason to pull the wheel please take the other measurements, If I am going to build these I would like to have them match the original Kitfox parts.
          Are you saying there are 2 different wheel bolt patterns or two different sizes of bearing outer diameters, The bearing sizes I am not worried about as I could just use the Azusa wheel bearing for a size, I believe they use a sealed bearing instead of a bearing cap on the hub.
         To save money I could easily make them 2 piece with the wheel hub TIG welded on then finish machine.
        I was not aware that there were 2 different bolt patterns, It would be nice to have both sizes so I could build either, or go with the easiest to buy wheel for.

    Well Orilley is over so I can now give some dimentions on the Kitfox hubs.  I measured some old hubs I had (from a Kitfox 1)  and this is what I came up with.  Looks like they were made from thick walled aluminum pipe with a plate welded on that the wheel bolted onto.
    The pipe was 2 1/4" OD, with 1 1/2" ID.  The bearings were 1 9/16" OD.  The plate was 3/8" thick, and was 4 3/4" diameter with 6 holes in a 4" circle.  The hubs were 4" long. The newer Kitfox hubs look to be a smaller diameter, maybe 2 1/16" OD (hard to measure accurate with the wheel on) and the bearings looked slightly bigger than the older hubs had.  If you still think you want to build, I can try to take a wheel off and get more accurate measurements for you.  I think the wheels have a 3" hole in the wheel.  Doesn't look like it would be hard to make some hubs using thick walled pipe and plate.  Jim Chuk

    I measured my Avid right after I posted my last message, and before I could repost that 7/16" is correct, I got a phone call that lasted till I had to leave home.  Back now so I figured I would tell you you are okey on the 7/16".  Jim Chuk
     
    PS  I also kind of measured a Kitfox hub.  Now if I can find that post......

    Luke,
         When you get ready to drill the holes for the little 7/16 tubes into the cross tubes, it is very important to get them absolutely vertical in both directions with each other - I set mine up in a milling machine to drill them both at the same setting.   And make sure the tops of the little tubes are at the same height above the crosstubes before welding them in.   Mine were set to .312 (5/16) above the 1 1/8 inch diameter crosstibes.
         When you set the crosstubes up for welding to the fuselage tubes, and to the headache tubes, you should make some sort of fixture to make sure your vertical tubes are exactly 27 1/2 inches apart on each side, and that the little tubes are vertical
     - I forget what the width should be, but think it is about 36 inches - I will try to check on that if you don't have it.

    Wel I am sorry I wasted your time, My brother has decided to swap the engine with the zero time one. You all gave me good advice but he said he will feel better with an engine of known  origin hanging off the front of the plane he is finishing his  light sport training in. I support his decision and we may need more advice on setting this engine up. Thanks again, Cliff

    Luke,
        The 5/16 ID is correct - you wont be wrong on the 7/16 OD.

    No problem guys. I should have remembered to measure myself. If I'm wrong it's not the end of the world though. I'll check when I get home tonight. May have to re-order with faster shipping. Pretty sure It's right though.

    An option I was considering was to buy the A3A Axles from Matco and bore a .75 Hole thru, then re-drill the caliper mounting plate to match the axle pattern. This saves a lot of machining. I learn years back it is less expensive to modify a mass produced part then to start from scratch.

    Well, I went ahead and ordered the 7/16" x .065" tubing. Should be here by the weekend

    Thanks Ed. That's a good thing to consider. I'll do some testing on some scrap first. Are my dimensions correct otherwise? I mean is the tube a 7/16" OD?
     
    Thanks

    I watched Kitfoxes CNC machine at work at the factory yesterday it's a pretty impressive set up.

    some may disagree with me - but I burned up a reamer on the 5/16 ID 4130 tube after it shrank with the welding - I would use bushing stock or 1020 tubing 2.250 long, and then trim it to 2.125 after welding.

    Prop makes a huge difference on these little planes. Have you verified the takeoff rpm with something digital or are you using a needle tach and the grey wire off the lighting coil? That set up is notorious for being inaccurate and a few hundred rpms also makes a massive difference.

    Help - Need tubing size
    Hey everyone. I just realized that I forgot to order one tubing size for my project, and I'd like to start on it this weekend. My plane is at home, so I can't measure the size.
     
    The tube I need is the one that the front spar attach bolt goes through. I'm pretty sure it's a 5/16 inch bolt, so I would guess the tube would be 7/16" OD tubing with a .065" wall. Then I could ream it to the correct ID. Could someone confirm this so I can order this today?
     
    Thanks,
    Luke D.

    The steel hubs would not add anywhere near the weight that the Grove gear adds.

    I know I have seen straight 3/4 inch hubs and axle shafts, but the weight would be the killer, that is why I would like to copy the kitfox assembly.
