I have an allis h4 crawler/loader.  I have a leak on the left side inside the loader frame work.    top fitting is easy to get to but the bottom is a problem.   has anyone ever replaced these lines.    looks like I might have to pull the cyclinder to get to it.

I have the crow foot wrenches to do this inside the shovel frames, best bet is relieve the hydraulic pressure, with the loader sitting on a framework or steel drums, anything to get and keep it off the ground then pull the front pin and remove the rear pin to retrieve the cylinder. Use the shovel arm as a support to lace up the cylinder in place then lift it out of.

Thanks Dave. I raised the loader up today to get a better look and determined I was going to have to pull the cylinder. wasn't sure how but you reply makes good sense.  Apparently some one had replaced the hose on the other side. they used a torch and cut a hole in the frame work so you can get a wrench on it fairly easy.  to bad  they didn't put factory holes in the bottom like the top. looks to be a job for oold weather thanks  norm

Hey Norm, I took an open end 1 1/2 inch wrench and heated the open end and bent to a 90 degree to fit the hose in the frame of my loader and used an adjustable wrench to twist the wrench to take my bad hoses off and replace. I believe the crows feet wrenches are an open end type wrench with an 1/2 inch drive slot to use an extension and ratchet / breaker bar to loosen  the hoses.

randaleky is correct in that mine are 1/2" drive but bought them years ago when I wrenched trucks and such, Snap On. Local CARQUEST had availability for them for a neighbor that also thought them the Bee's Knees. Usually a set comes 1/2 0r 3/4" up to 2 or 2 1/2" in 1/8's

here is how I changed a hose in the loader frame of my HD6G

I used (2) combination wrenches connecting the box ends with a piece of hex stock. I used the open end on the fitting

Thanks for the info. I looked them up on ebay today. I see what you all mean. top hose isn't a problem but the bottom is. Had to replace a long hyd hose on my back hoe last week. took it to the cat dealer we have here. cost me 35 for a 4000 lb hose. so these wont cost to much but will cause me allot of trouble getting it off.  to bad the bottom doesn't have a cut out like the top. engineers never design anything to be worked on.  thanks  norm

they think anything they design is forever !!!! If they had to work on the machines it would be different.
