Snapped bolts - how do I un fk it?
Submitted by Swompa on Sun, 2019-08-25 19:54
Trailer Birthday time...
In past topics, I have bagged out my Pappas trailer due to the amount of rust on it even after a severe wash down each time and it has kicked off.
All was going to plan with the boat coming off easily and all bolt on bits coming off relatively easily but when it came to the brakes, what a pain in the arse....
Both bolts holding the brakes onto the axle have snapped on one side and on the other, the top bolt came out easy but I can't budge the bottom. The two that snapped had less torque on them than I had on the wheel nuts..
So brains trust, how do I fix this? Kinda thinking it will be a cut the bit off and weld a new bit on?
The brakes were beyond rooted hence the removal.
Oh the joys of having to do it yourself...

Cut what you can off. Redrill
Cut what you can off. Redrill and retap the threads.
Does anyone know where the love of god goes, when the waves turn the minutes to hours?

My trailer was ten folds
My trailer was ten folds worse...but surprisingly them bolts came out, only ones o didn't have to cut.
Cut / get the calipers out the way..soak / spray for few days...try center pop...drill, sharp low speed good pressure...then easy out.
If you get stuck, I have two spare plates, we can cut them off and weld new ones on...few hours couple beers.

Weld nut on what's left of
Weld nut on what's left of the stud, heat from the weld will generally free up stud, run a tap down the holes to ensure they are clean

HEAT HEAT HEAT HEAT
and, if I'm not clear enough, HEAT!!!
I have snapped the exact same bolt, 4 fuckin times on my old mans Dunbier. get some map gas/oxy-acetylene/etc/flame torch and heat the plate til it gets red. you should then be able to use multigrips to remove it.
failing that, heat it up and shock it with water. that is a never fail!!
when you replace the bolts, use molybdenum (moly) anti-seize. you can but it in a chap-stick type container from most auto shops. never had a problem since using it.

So heat you say? The stud
So heat you say?
The stud was inconvenient enough to break inside the threaded section so there is nothing I can grab.

Just a thought
Why do you need trailer brakes on a boat that size ?
Not as if these a lot of weight there Single axle and center console.
Dont think i would bother.

Don't know how much it weighs
Don't know how much it weighs to be honest. I do recall that when it was first put on the road, we had to remove an esky I had made for it as it was very close to the weight limit so when we got this trailer, it came with brakes.

certainly not much fun when
certainly not much fun when that happens . hope you can use some of the info given to get the job done or you could park the whole trailor on the verge over night, surely someone will pinch it . then with insurance you can get a new one.

Weight
Get it on a weight bridge and you may find you don’t have any problem just looking at the pics of the boat I would be surprised if you needed a braked trailer.
However, if you do, then as been said above heat the hell out of the threaded area, then throw water on the hole and the use an easy out toget the rest of the stud out. This will involve drilling a hole in the remaining stud in the hole, this drilled hole is to be about 2 thirds the diameter of the stud, then screw the easy out into the hole. And walls the stud should just screw out.
Phone shark 1 and take advantage of his most kind offer if the above fails, mind you I think the Faulkner family suggestion has a lot going for it also.

Tips please
Can't help you with the brakes Swompa, but I also need to do some repairs to my tinnie trailer.
How did you get your boat off in the back yard, is it sitting on tyres?
I have a heavy edgtracker with a 30hp.
thanks

I used to get my 4m tinny on
I used to get my 4m tinny on and off regularly. If you have lots of rollers, like my glass boat, it's harder to keep the boat on the trailer so I eased out 200mm increments of winch rope just so it didn't gather momentum. Had to tie off the hitch and push the boat.
With the tinny, I had to hose down the slides and lift the hitch end and shake it. Always keep a little bit of tension on the winch so you don't get out of control.
I have this boat on two tires at the stern and stacked pallets in the bow to hold the bow up so I can get it back on the trailer. Just sitting on the ground will involve a vertical lift to get it on the trailer once were all done.

Tie the back of the boat to
Tie the back of the boat to something sturdy and slowly drive off put a couple of tyres under it. A star picket in the ground works well.

Try
Two Tyre stack x 2 and 2x lengths of timber as side braces to hold straight(upright).

get rid of the rust by......
drop rusty bits in to a 1 litre molasses : 10 litres water mix (Make sure it IS mixed well).
Leave soak for 2 weeks.. careful it willl probably smell towards the end.
THis solution will strip rust back to pristine metal that is "like-new" WHen you take it out, wash the parts and apply paint/primer/ sealer ASAP... if not sooner. If you do not protect the metal you WILL see discolouration occur as rust begins to grow on the 'new' surface.
If the bolts still dont move you may have to try heating and swearing........
Brakes must be the problem of the month..... I checked one of mine this morning.... and it is in the molasses bath.... Luckily I got the mounting bolts out but I will have to retap the mounting holes and probably replace the bolts-- I really had to lean on the socket-bar to move them. Wish I'd thought to spray the other side bolts so they may be easier in 2 weeks time..

Molasses is an interesting
Molasses is an interesting on!
got out the angle grinder and politely removed the final bolt this evening. There was enough sticking out to get the multi grips onto it but she ain't moving so far. Next step is to take the hubs off to get access to the 'other' side and soak the bastard in some form of lubricant before getting emotional with some tools.
Not quite as daunting as initially thought. Thanks for the tips and info!
