Newby with CAT 305.5E2 (not CR) -- I think the tracks are toast. Do I need new sprockets?

[skyking1]

If it does not, get a couple of teeth and weld those to the plate. Then you beat the pins out to remove it. That is the typical arrangement.

Or I've seen chain both sides and a ratchet binder to pull it on tight

Treasures from the farm dump:



@Truck Shop vintage semaphore signals!

 

[Baxsie]

Maybe it is a "Truck Semaphore Turn Signal #221 Detroit Products Co Bus Light Arm". Apparently some people think they are worth something:

Another load of scrap to the recycling yard:



There was a big wad of scrap steel stuck in the bed. I was walking over after taking the photo to figure out how to get it loose when this happened:

The big scrapper crane plucked it out so quickly and precicely!

 

[skyking1]

that has to feel so good to see gone gone!

Some of those scrap yard operators are really good. Others are really good at bending your trailer or truck.

I think that makes 9360 pounds of scrap steel so far. Plenty more to go.

With the age of my truck, having it mistaken for scrap is a real concern !

He seemed to know exactly where that hook was going, and was not slow about it ! Yeet !!

Usually I just dump and leave. This time there was an old truck service bed of some kind jammed in there making a big glob of stuck together stuff. I'm not sure I could have worked it loose quickly by hand, so I was happy to have the crane's help. Perhaps also lucky with no damage to my truck

4:36 pm on a Friday.

I started seeing a fine grey mist every time I closed the thumb.





Probably not able to get a hose until Monday.

I had been working on this big grain bin:


Crunching it up so I could fit it into the truck:


So job done, but now a break to fix hydraulic hoses.

I'm thinking clean it real good, a drop of super glue in the hole, 4 or 5 tight layers of electrical tape to seal it, then a couple wraps of Gorilla tape for strength. It will be good to go!

I am wondering if the bypass for that cylinder is set too high

Of maybe it is just an old hose flexed too many times.

 

[Baxsie]

@Nige The hose is supposedly a "263-7001 HOSE AS". Is there a way to tell how long it is and what fittings are involved?

My plan is to go to the local hose shop on Monday, taking in a sample. Would this need to be 2-wire or 4-wire?

Would you replace both hoses or only the one that has failed?

In other news, I think my stick hoses are routed incorrectly. They are outside the ears and I think they should be inside the ears.

I have seen people on youtube that have hydraulic plug and cap kits. Is there some standard that CAT uses on these minis? Would something like this JIC and ORFS kit work? Do I need an ORB (O-Ring Boss), BSP or NPT kit ?

 

[Tones]

My preference is to keep as far away as possible with 0 ring fittings. They have a terrible habit of failing when you need the machine the most. It a tiny inexpensive item that costs a lot.
The stick hoses normally are outside and keep the sag close to the boom and dipper.

 

[John Shipp]

"Would you replace both hoses or only the one that has failed"

A few years ago I would replace both and maybe even buy a third as a spare. Today I would be asking them to cut out the bad bit and crimp a new end on

Really, it depends on the condition of the other side, with how far to the hose shop, how much more work to do before selling it and how lucky you feel factored in...

@Nige The hose is supposedly a "263-7001 HOSE AS". Is there a way to tell how long it is and what fittings are involved?

Yes there is. It's called HIS (Hydraulic Information System) but is only available to Cat dealers and selected customers, to help them build hoses obviously. We had access to it because we had an on-site Cat hose shop. Chances of your getting the info - slim to none.

if you go to a hydraulic shop just take the old hose as a sample.
Should you replace both.? Depends on the condition of the other one I would say.

In other news, I think my stick hoses are routed incorrectly. They are outside the ears and I think they should be inside the ears.

Post some photos showing how the hoses are run.

Post some photos showing how the hoses are run.

On one side, the bucket cylinder hose droops down :


On the other side, it is buckled upward :


Most of the pictures I found on the internet have those two hoses going between the big ears on top :





The bucket extension hoses and the aux hoses ( the one with leak) kind of interfere. I tied the bucket hoses together with a string to keep them out of the way a little bit.

I'm thinking, as long as I'm screwing around with stuff up there, I might as well reroute those hoses properly.

 

[Nige]

The photos you found certainly look more “right” than your machine. Only the Parts Manual will reveal the full story.

 

[Baxsie]

@John Shipp When Monday rolls around I will take off the bad hose and take it up the hydraulic shop. If it is not too expensive, I'll get two, if it's really expensive maybe I'll just replace just the end or get one.

Both of those hoses seem to me like they could lose an inch or two in length and not miss it. It seems like a big unnecessary loop -- as far as I can see from internet photos that's the way it was from the factory.

 

[John Shipp]

The 4th pic in #214 shows the aux hose the other way up to your machine and the 3rd pic. Would think that would get quite a pull on it when the dipper is crowded all the way in towards the boom. How does yours look fully crowded, still big loop?

 

[Baxsie]

The photos you found certainly look more “right” than your machine. Only the Parts Manual will reveal the full story.

This SIS2GO pic could be interpreted as indicating that the bucket hoses go through the ears:



The aux lines do not look like mine or the bulk of the photos I have found:



Most pics I have found -- as well as my machine -- have an elbow at the lower end, a spring around the hose, and a big S curve:

Ya. I pulled that pic because it showed the routing of the bucket hoses between the ears. Neither my machine nor most of the pics I have found on the internet match the machine in that photo, so I assume it is a rework of some kind.

 

[Nige]

I would agree.

The aux lines do not look like mine or the bulk of the photos I have found:

Look for a part number tag on one or other of the steel lines that run along the boom on your machine then search your SIS for that number.

 

[Baxsie]

I took a shot at rerouting the bucket lines between the ears. I think it looks a lot better. Here is the stick fully extended:



And here is the stick fully retracted :



There is no tension in either position and no leaks after a quick test so I think that's a win.

I noticed that one of the steel tubes that feeds the right hand aux line is bent. Perhaps it's not coincidence that it's bent on the same side that the hose is damaged on .



The line on the other side just goes straight where is this near side kicks up. I'm thinking it doesn't affect anything functionally, but cosmetically it bothers me. Would I be completely stupid to try to put something on that pipe and straighten it out? Are they more ductile or I'm likely to break the dang thing off ?
