LostPiker Posted November 9, 2020 Share Posted November 9, 2020 Got all the bits to rebuild the trailer. Main bit is a complete new axle. I expect all the bolts to be rusted solid so will need cutting off to remove the old axle. What do I do with the boat while I do it? Will it be OK to push it off on to the grass then pull it back up with the winch when it's done? The trailer has rollers if that helps? Don't want to damage the hull, it could do with a coat of paint so not worried about minor scratches but don't want to wreck it Quote Link to comment Share on other sites More sharing options...

As a last resort I could but it would be 100 times easier to get the boat off and flip it over. I expect to need to cut all the bolts off and I have a big scar across my forearm from an accident with an angle grinder when I used to restore classic cars so I'm quite cautious with them now Quote Link to comment Share on other sites More sharing options...

I’m sure somebody with more trailer experience than me (that’s not hard) will be along soon to offer a method of boat removal. Quote Link to comment Share on other sites More sharing options...
Andy135 Posted November 9, 2020 Share Posted November 9, 2020 I've heard of the "roll it onto the grass" technique, but I've never done it personally. Getting it off sounds straightforward enough... it's getting it back on that concerns me. Seems like the hitch end of the trailer will end up pointing skywards unless you hitch it to a tow vehicle, which then means the boat has to climb up onto the rollers by itself, which is something it was probably never designed to do. Last thing you want is to crack the keel or pull out the towing eye. When I replaced the axle on my first boat I just jacked the trailer up (including boat) then blocked it off and dropped the old axle. I didn't use a grinder to remove the old bolts - mine came off with some penetrating fluid and a breaker bar with extension (aka a 3 foot length of scaffold pole slid over the end of the breaker bar). If I were to do it again I would investigate this route first. Even if you find you need to grind off the bolts I'd still do it with the boat on the trailer. You should be able to access the bolt heads from above the axle, thus avoiding the need for grinding from underneath and risking sparks, swarf or spinning grinders falling on you. One other suggestion - you can buy nut splitters quite cheaply. Could be a good (read: safer) alternative to grinding them off. https://www.toolstation.com/nut-splitter-set/p80007 Quote Link to comment Share on other sites More sharing options...
jonnyswamp Posted November 9, 2020 Share Posted November 9, 2020 Lower the jockey wheel all the way down, so the stern of the boat is at it's highest Put some beer barrels/railway sleepers under the stern (near the edge where it's strongest), then wind jockey wheel up as far as it goes and put some timbers/supports under the bow sides, so trailer can be slid out You may also need a good trolley jack, depending on the trailer design I did this with a 23ft Bayliner that weighed around 2 ton JonC and GPSguru 1 1 Quote Link to comment Share on other sites More sharing options...

suzook12 Posted November 9, 2020 Share Posted November 9, 2020 I completely redesigned my trailer and it picked it up off the grass a treat, I just left the car handbrake off so it wound the trailer under the boat....... Quote Link to comment Share on other sites More sharing options...

JDP Posted November 9, 2020 Share Posted November 9, 2020 Ive done it a couple of ways, first and easiest is simply heading somewhere where you can launch the boat and tie it on a jetty while you do the work in a car park. You need to have all the tools and parts to get the job done, easy for one person. Second method I have done with several of my boats and other people's is to slip the boat off onto grass but place old 4x4 tyres under it as I slide it off. Using tyres allows me to keep the boat in its upright position rather than have it fall to onside. It also protects the transducers and the hull from marking on anything on the ground. This way also greatly helps when you go to get the boat back on the trailer because it is already slightly up off the ground lay in the right position. Just to add I normally take the trailer off the vehicle to get the boat partly back on, this way I can allow the front of the trailer to raise off the ground lowering the back to get under the front of the boat slightly. Depending on how good your trailer rollers of skids are, you may need help sliding the boat off if you are on level ground. Ive always been able to find something to tie the back of the boat to and simply drive my vehicle forward slowly pulling the boat off. Slowly is the way to go and don't try and drive straight off in one go, hop out of the vehicle and check you are happy with the tyre placement. Almost any tyre shop that fits tyres should be able to give you 4 tyres. Trying to do this without tyres can be done but it makes it far more difficult to get the boat back onto the trailer. You will need to make sure your winch strap is in good condition and the bolts holding the winch. If the winch hasn't got low gear you can simply run the winch strap to the boat, round a pulley and back to the trailer. If the winch has steel cable you might want to consider changing to dynema rope or webbing a trailer webbing strap. Quote Link to comment Share on other sites More sharing options...
Geoff Posted November 9, 2020 Share Posted November 9, 2020 If using the tyre method, I think it would be worth investing in a bottle of fairy liquid to ease the friction when sliding the boat. Geoff. Quote Link to comment Share on other sites More sharing options...

Geoff. Not sure I get where you want to use the fairy Geoff. I assume on the trailer rollers or skids, not the tyres. The boat shouldn't slide on the tyres at all, more a case of slipping the trailer back under the boat as it winches. I put the boats back on with the trailer off the tow vehicle normally. The front of the trailer will rise up a certain amount as the back pulls down under the front of the boat. Quote Link to comment Share on other sites More sharing options...
LostPiker Posted November 11, 2020 Author Share Posted November 11, 2020 So I had a go at this last night. Turns out I was worrying about nothing. I jacked the trailer up and got it on 4 axle stands and took the wheels off. The axle is bolted to a piece of angle iron on each side that has the mud guards mounted on some steel straps welded to it. These are then attached to the trailer with 2 square u bolts on each side. Access was easy to the u bolts and could easily cut through them with an angle grinder and pull the axle out. Waiting for some more u bolts and stainless bolts and I can get it back together. The new axle has everything ready to go. I have rebuilt the overrun unit by buying one that was the same from a caravan and stripping it down and rebuilding mine with the bits so that is all ready. The galvanising where the angle iron attaches to the trailer is worn off and I need to clean the rust off and paint those bits, other than that the trailer will be all good to go.

Andy135 Posted November 11, 2020 Share Posted November 11, 2020 Good work. Having done the same myself I did wonder if you'd find it easier than expected - there's literally nothing more than a few bolts holding the axle to the chassis in most cases.

JDP Posted November 11, 2020 Share Posted November 11, 2020 I notice you seem to run ordinary non marinised car wheels on trailers over there. That trailer above looks to have massive axles yet light weight poorly galvanised box sections. Quote Link to comment Share on other sites More sharing options...

suzook12 Posted November 12, 2020 Share Posted November 12, 2020 Ahhh gotcha Think most small trailer wheels are supplied galved these days..... I can't say I've looked at ally wheels, I usually go by payload specs, something that often gets overlooked, and all the ally wheels I've seen are aimed at cars.....

But, can't say I've looked so couldbe wrong there Most people here have aluminium wheels on their 4x4 tow vehicles and often try to match the boat with at least the same stud pattern, which then means you are carrying two spares rather than one. Once we start getting into remote areas the chances puncture increase, most we can fix by ourselves but I have damaged two so badly in the past that I had nothing left if I got another!!! My trailers tend to last far better than most due to spraying them down with salt-away after each trip, this is the same solution I use to flush my engine after use. Every now and then I go around the trailer giving it a spray of lanolin, or at least I normally do but my current trailer is aluminium so not much of an issue. We can get locally made aluminium trailers or kit form from China that you simply bolt together. All have to meet strict Aus standards and all trailers in most states need to be separately registered, insured and inspected every 12 months, the same as a car. Ive moved away from roller trailers as they are more problematic than simple skids. Also getting boats on and off on skid trailers is just so quick, especially where we drive on and off.

TBF, most steel wheels supplied by trailer manufacturers are crap ........... mine are 18 months old and showing quite a lot of rust, despite being washed down after every trip. However, this winter I will get them powder coated ......... that seems to last OK ............ JonC and Geoff 2 Quote Link to comment Share on other sites More sharing options...

Yeah, thats fine when you're talking 4x4's etc, they will have durable wheels with significant load rating, when they're from a fiesta or similar, the same can't be said.... Kit form from China.... Dunno why, but just don't fancy that idea!! I think trailer testing is a good idea, say anything over 500kg laden or unmarked, that way all homebuilds end up with serial numbers and can be seen to be suitable and of a high enough quality...... I adapted my own trailer away from carpeted bunks to roller bunks, but also with tail and keel rollers, that winds the boat up off the grass no worries JDP 1 Quote Link to comment Share on other sites More sharing options...
