Hydraulic line Connectors?

4652 Views 43 Replies 6 Participants Last post by  Just Wondering
I'm rehabbing this 1957- 330 International tractor which has a front bucket on it.

I'm working on removing the 3 cylinders and getting them re-packed.

To remove a cylinder, I have to release the hydraulic hoses.

This is a frankenstein collection of adaptors/connectors, metal lines, galvanized pipe, elbows, 3-way t connection...ugh.

I have no reason to keep the eclectic collection of connectors -- partially rusted, completely rusted, new ... ranging in size from 7/8 inch, to 1 inch, and larger -- some of these parts are SAE and others are metric.

Hoses on 1 side are original to the machine (yellow overspray paint), those on the other side have been replaced (no yellow overspray paint). And of course, if a 20 inch length of hose is good on one side then a 40 inch piece with a large curve in it is better for the other side.

Bless the soul of the prior owner for being creative and solving the hose connection problem with a minimum of cost and probably a maximum of labor.

What's a better way to solve this problem?

I'll have to check the size of the openings once I get the hoses off so I know the minimum size.

Those are called cotter pins or cotter keys.......Any auto parts store or farm store will have them in all different sizes....Do you have one of the old ones to compare for sizing?
Actually, on hydraulics you want Hairpin cotters and Tractor Supply (TSC) will have them in any diameter (hole size) you require. Usually sold in multiple packs.
Roll pins of the correct size would do the job also.
Problem with that is removing them.

But!! what is wrong with using a pin punch and a ball peen hammer?, I think I know what I would prefer to use when the time came to remove a pin, imagine the fun trying to straighten out a cotter pin of that size Bekasu mentioned, most people wrap both legs around the held pin, just a thought anyway.
Nothing but a hairpin cotter (spring pin) is so much easier. I have some pig one I've never used in the drawer. Split cotter pin.

You mean "R" spring pins !!.(y)
If that is what you call them over there, fine with me...

I think that we are talking about the same thing.....I should have posted a picture of what I meant so she would know......It is funny how the exact same thing can have several different names depending on where you are in the country or world and who you are talking to.....

I worked for an old knuckle dragging Warrant officer one time that was a former mechanic. One of his famous sayings was...."Don't force it, get a bigger hammer"........His favorite tool in the whole wide world was what he called a "BFH".....Anyone ever heard that one?

I have two sizes hammers I really like for the "persuasion" jobs ...... "BFH's"(3-5lbs) and a "GBFH's"(10-12lbs +). I still have a custom made GBFH I used to drive bent anchor pins out of push-out cylinders on trash trucks. 20LBS head, welded to a 24" handle, made from a piece 1 1/2" steel rod..... I call it "Bertha";)

LOL.......His BFH was a custom made job.......He had someone at some point forge him about a 25 pound head and then weld about a 4 foot piece of 2 or 2 and a half inch pipe to it. Then they weighted it with about 5 pounds of big ball bearings and welded a cap in the end.....So when you would swing it, you got the extra force of the bearings going from the end of the handle to the head......Some major damage could be done with that thing......LOL

When you reach the point of frustration/desperation where you break out a hammer like that, you're beyond the point of worrying about "major damage" and that actually becomes your intent. They have parts houses and make welders to correct the situation for when you finally come to back to your senses, but for that tiny moment..... You get to feel like you won, until you realize you now have two halves of the part:cool:

Yep......And when you are active duty military, Uncle Sam pays for the parts......That was his thought processes.....

Yep..... When I beat the crap out of a part with a BFH... It was never on something that I was footing the bill for the replacement. Nobody ever questioned it, and if they did, I always figured I'd just show them the two halves and say "This is pretty badly worn";)

Hairpin cotter ....Excellent.
I've been over at Steiner searching for the hydraulic filter which I'm sure needs to be replaced.
So far I have 4 days of spraying bolts with pb blaster. Hoping to make the bolt removal easier.

I can use the tractor to pull that seat off and the big, square, heavy cover off the hydraulic compartment so I can change the filter.

Already scoped out a battery for this beauty.
woohoo.

Hairpin cotter.

I am continuing my journey. Yesterday was a remarkable day after several windy, chilly days. Sunny and blue skies.

I managed to remove the seat cushion.
I removed all the long bolts holding the housing for the hydraulic fluid.

My goal is to get to the hydraulic filter.

Its now weeping hydraulic fluid around the base since I've pulled the bolts and released the tension.

Sucker is heavy.

My hope is the Mr. will feel well enough to use the tractor to lift it off so I can clean it out and pull the filter (assuming it has one in there-- never know with previous owners).

Then replace the filter, add fluid and put the bolts back in. Use my permatex to put the hoses back together before the cold weather kicks in.

Oh, and that brand new tire for the front left wheel is sitting flat on the ground. Bummer.

Be careful with the permatx. Pumps don't like foreign substances.
Finally got the top cover off the hydraulic area.
But had to stop and take Mr. to the doctor today and to get glasses tomorrow.
But I'm hoping to clean it all out by end of day on Thursday and put back together on Friday if the co-op has a new filter.

It has relatively clean hydraulic fluid but there is at least 1/4 inch of gray thick goo at the bottom of the hydraulic pan.
Just disgusting.

I'll be careful with the permatex. A little goes a long way.

JW
With the help of my Mr., got the hydraulic cover back on.
Used permatex as my gasket. Was careful to wipe the sides clean so it was only on the mating surface.

Got all the bolts back in and run down.

I have 2 more lines I need to replace.
Once I get those, I'll permatex and tighten all the lines and move on to the fuel system.

Yes, I have new hydraulic fluid to put in but have to figure out how to get the fill plug out first. I don't have a 'square' wrench.

I also have two flats on the front. Looks like I need to tube those tires before I go much further.

Need to sew a new cushion as well as get new foam... the old one is toast.

JW, have you measured the square recess, a lot of plugs were close to the square drive on a 1/2" socket extension, if it is not 1/2", then use a bolt that the shank is bigger than the square recess and grind a square to fit the plug, then use a socket on the bolt head to undo.
.
It looks to be more like a 1 inch square. I'll see if I can post a picture from my phone
