Re: Trailer door hinges. I think someone else posted this same job before.
We fix a lot of these hinges. Your repair looks pretty adept. Squeamish weld considering the base of the trailer.
One thing that happens on this mode of hinge if the pin is fit very tight is that there is interference between the trailer and ramp on the swivel rotating parts. Some commercial replacement hinge assemblies have a raised or pointed expanse that is to be the welded office. This puts some space between the hinge pars. Information technology's hard to describe but I've you always fit very tight pins you volition run into the trouble. Commercial aluminum hinges usually accept this feature.
You wind up grinding a relief in a difficult area. I sometimes put two welds Adjacent on the ends of the hinge then weld solid. This spaces the door slightly away from the frame of the trailer. I simply fixed one a calendar week ago like this.
Never the less nice repair.

I infinite a couple different things. I space the 'moving' part of the swivel away from the trailer and then it has clearance for future rust and dirt. I likewise leave infinite betwixt the terminate of the welds and the moving part of the hinge so each hinge has some lateral clearance/play. Then manifestly the pin to barrel has to have some clearance or it would be a press fit. I employ different clearance here for different situations. For these I put in .020-.025" clearance.Many time I like to put a washer or lip on the pin to ride on the moving part of the hinge. I felt information technology wasn't really needed hither.

You lot got it right! Very nearly the same as we do. You only make this mistake once.LOL
We also try to use greaseable hinges where possible. However few people ever grease them. At least we gave the opportunity.
Virtually of these landscaping and equus caballus trailers are rusted hulks. All of our new ones are aluminum. They hold up better even in our winter common salt laden snow.

Re: Trailer door hinges. I think someone else posted this same job before.
It looked like the old hinges were drilled for grease fillings. Either they never had a zerk installed or most likely never would see a grease gun anyways

Re: Trailer door hinges. I think someone else posted this same job before.
Yeah, most wont grease them anyway....information technology's the idea that counts.

Re: Trailer door hinges. I recollect someone else posted this same job before.
Yep they had holes for zerks I believe. There was no zerks, no grease, and lots of rust. lol Originally Posted by akpolaris It looked similar the old hinges were drilled for grease fillings. Either they never had a zerk installed or virtually likely never would see a grease gun anyways
I'll indicate out the zerks to them. I'll even tell them how to use them. The grease I shot in might be the last information technology ever sees though.

Re: Trailer door hinges. I call back someone else posted this same task earlier.
The process you did looks great, but the nubie wants to know how you lot become welds to stick to rust? Seems as though no matter how much you grind those areas, that there would be so much porosity (rust pockets) in the steel ???
Is in that location specific types of stick electrodes meant to cope with this, or were you actually able to become downward to clean metal?

Re: Trailer door hinges. I think someone else posted this same job before.
The rust needs to be ground down to bare solid metallic or any weld will exist junk. I see this very often in these trailers. Sometimes the entire crossmember is so rotted it needs to be replaced. I did a landscaping trailer final twelvemonth that I had to cutting the entire rear door frame and frame crossmember out. The repair cost was close to the price of a new trailer although I replaced the floor as well.
This is what happens when basic maintenance is not done on cheap trailers.
Horse trailers often sit down in manure soaked clay or grass and the acids simply consume upward the steel frames. Even aluminum cooorodes. These things are just a mess. Most of the time information technology'south non even necessary to look at the brakes either. Just salvage time and money and replace them. Wiring is the same. If it doesn't piece of work just retire the entire trailer as most likely all grounds are shot Wires become cleaved or rotten in enclosure tubes and you can't even pull them out.
If people would just pressure launder these trailers a couple times a year they would save big repair bills.

Very truthful - I did some livestock trailer alterations for an sometime guy concluding year. Trailer in perfect condition for approx 20 years old. Originally Posted by bentwings If people would just pressure wash these trailers a couple times a year they would relieve big repair bills.
I asked him about why it looked so good - said he ever pressure washes it after he's used it.
@VPT - nice job on those hinges

Re: Trailer door hinges. I think someone else posted this same job before.
Thanks!
If y'all await existent close you lot tin come across I did grind downwardly the rust to blank metal, but just. If you can run across there is near a 1/4" buffer all around the weld from the area that was basis down. I don't get to carried away with cleaning to far away from where I will be welding.
The rust is mostly merely on the surface, what you lot see pealing in some pics in the bedliner that was sprayed downward when it was newer. All the metal had good thickness to it notwithstanding, there is no real rot on the trailer anywhere that I noticed. The hinges just seized upwards and and then the metal was fatigued from opening and closing the door.
The trailer should exist pretty well shot before the hinges rust up again (if they never grease them).

Re: Trailer door hinges. I think someone else posted this same job before.
When there is not much material to brainstorm with and so rust makes it even thinner I use my little portable sandblaster to make clean downwardly to practiced steel and saving as of structure I can.

I've done a few repairs on other people's trucks, trailers and equipment... e'er leaves me wondering why the most bones maintenance is never done. Isn't occasional cleaning and greasing cheaper in the long run than repair or replacement? And when information technology comes to repairs aren't these the same guys that request it exist done quick and cheap? I've done a couple of repairs/rebuilds to dumps- the dump swivel seized and ripped out or the dump hoist got to the betoken it wouldn't lift a load because the dry out pins had stuck in the bores... when the truck is serviced why wouldn't he keep going front to back and grease the dump equipment also?

The trailer should be pretty well shot earlier the hinges rust up once again (if they never grease them).
The door leaf frame is pretty toasty, and your prediction of the trailer crapping out before your welds may come to exist, but greasing them sure would assist, eh?

Re: Trailer door hinges. I think someone else posted this aforementioned task earlier.
I practise, I always endeavor to explain what happened and how to avoid information technology in the futurity. Some do the maintenance some don't. Originally Posted past T man Sweet. Your welds are quite handsome.

Do you edjumakatethe customer when they pick up their finished production?

I actually discover it is the women that volition listen the most when you explain something or why something happened and how to keep it from happening again. Like y'all mentioned, most men are all "Yup, uh huh, ok, got it, then its ready to become? How much practice I owe you?". lol

Re: Trailer door hinges. I recall someone else posted this same job before.
I'1000 not seeing the two failed attempts of hinges? Rusty hinges are the norm around here. Both the door frame and the door lip itself were practiced metal yet, they merely have surface rust going on.
I've repaired those hinges you posted also. Aforementioned lawn company has a dual gate dump trailer with those hinges you posted. Its been back here twice possibly 3 times now for hinge repairs. One of the issues as well rust with the hinges y'all posted is they are weak. They bend just from looking at them let alone driving mowers over them.
The other issue is funds, I get told to just make information technology work again, only don't spend do much. lol
Last issue is fourth dimension. I get these trailers commonly at the end of their mean solar day and they want to pick them up the next morning. If stores are airtight I tin't become anything, when they are open near don't take "weld on" hinges of whatever size in stock. No time for society and wait so most times hinges become made in the shop.
These hinges piece of work just fine, have been for the final 10 years or then on this trailer. They merely quite working when the maintenance team fails to exercise their job.
I use the tube and pin hinges quite a lot. They are a great heavy hinge. I've never tore one off or had ane seize up on my own stuff.

Re: Trailer door hinges. I think someone else posted this same job before.
Imo, the task you did worked out just fine.
Instead of looking at opus answer as a negative, condescending post, which is how it comes across as, I look at it as another choice for a future repair downwards the line..
Not sure why some experience,the demand to degrade other peoples work, and label them as applying failed techniques, when what you did volition last equally long as the rotted old trailer you worked on will proceed to exist in service.
Is the other pattern superior? Could be. Just equally you stated, you accomplished what yous were requested to exercise.

I don't mind the feedback. It is how we learn. If anybody simply says nice job no thing how the task is done merely to make the guy feel good no ane learns anything.
In this case I know the alternative and its ain new set up of issues. If those hinges bend the door doesn't shut. Also like I mentioned they rust up and seize too (and don't have a zerk to prevent it). There is no real "all-time" option for heavy door hinges (well mayhap an all stainless something or other). There especially is no better option over night on a holiday weekend. lol

Often what I find on these jobs, since the customer is always right, is that time and money (meaning quick and inexpensive) win the 24-hour interval over skilful blueprint.

Re: Trailer door hinges. I think someone else posted this same chore before.
Especially with a personal (annihilation really) trailer. At what point do you draw the line? Meliorate hinges, can make the door frame amend, could make the door itself better, could brand the trailer frame better, and so on. Could do stainless brawl begetting hinges with seals.

Re: Trailer door hinges. I recollect someone else posted this same job earlier.
We do use stainless hinges occasionally. Most of the ones we use have plastic bushings. Nylon or UHMW. Some are steel with grease fittings. Some we make ourselves with grease fittings.

Re: Trailer door hinges. I think someone else posted this same job earlier.
I love hinges (especially stainless) with the nylon bushings!
I have made up a number of stainless hinges, mostly for the family bait business concern since everything is in water and common salt gets added to the water all the time.
