Thread: Cat Trailer Refit.

    Re: Cat Trailer Refit.

    Looks the goods, youve gotta love it when a plan comes together. I have covered my axles in a puty/mastic tape, need help from other members here as I can't remember what it's called, but once applied you'll never have to worry about your axles rusting. How did you treat the areas where you appear to have screwed in the piping for your irrigation system as these are now potentially new rust spots.

    Edit. Just remembered, I think it is called Denso Tape

    I'd be screwing a cover over that pump or it might go walkabout.
    AKWA marine in townsville have gone out of chandlery and they still have some quite large washdown pumps at half cost on the shelves. You could buy over the phone and get them to post.

    I went above the gal bracket and went straight through the ally frame. No holes through the gal.

    Give them a call they usually ship to you in a couple of days. Make sure they send you the newer stainless fill/drain plugs the original ones don't last that long before they strip.

    i see durahub advocate the use of the non marine seal

    that you normally use on box trailers etc. Any thoughts on this?

    Re: Cat Trailer Refit.

    Basically the marine seal is useless for keeping oil in. And many would argue for keeping salt water out. I went to Durahub 5 years ago on my off-road boat trailer and I still have that same set of bearings in it and they are like new. I am very paranoid about my boat trailer bearings and used to check them every six months even though I would check and pump the bearing buddies if necessary on every trip. Not once have I ever had no evidence of salt water getting in and would end up replacing them.

    On the single axle off road trailer I haven't had any water intrusion. On the dual axle trailer I would occasionally get a small amount in on hub. I never worked out what it was but would simply drain the bearings once I got home and top them up the next day. Same set of bearings lasted me more than 3 years before this refit.

    All moving seals leak, nothing a once a year wipe won't fix.

    The Durahub uses oil or a combination of oil and grease. A marine seal will have the oil completely leak out and defeat the purpose.

    I can't imagine why a marine seal would leak any more than the old style ones Lovey.
    Running durahubs the first thing I'd do is fit speedi sleeves.

    That Bunnings rope--if it is the stretchy stuff they sell at the checkout, it WILL sunrot very quickly. I had a bit securing a dinghy leaning up against a fence and it just went to powder in no time flat, sorry to say. Of course, yours is only exposed to the sun when the boat is off the trailer (?) so it will only be getting a fraction of the direct sunlight time that mine did.

    Re: Cat Trailer Refit.

    we have been oiling filling our hubs for years now with and without the use of the Durahubs, he no longer makes the Durahub for the 63.5mm hubs so we had to do our own thing but we always use a marine seal not a standard grease seal and have never really had an issue that I can think of.

    Re: Cat Trailer Refit.

    The issue at times is not failure of the seal.

    Sometimes the portion of axle just behind where the seal contacts the axle begins to rust. As the rust continues it starts to rust under the seal and forces failure.

    For this reason...... whenever servicing the wheel bearings give the back of the axle a good smear of grease to help prevent the rust, some even clean it right up and paint the back of the axle with gal paint to help stop the corrosion working back under the seal.

    Is the 63.5mm the Landcruiser one? I can't see how the marine seal would hold oil? The standard seal has that little spring that keeps the rubber tight with the axle.

    It's the Dexter 2 tonne hub. we have been using them for years and they have been great, The only time I have seen one fail was on one of our trailers that mostly gets put in off the beach but even then that was only on 1 axle and I'd say he had it bogged to the arse as it was full of sand.
