154 hydraulic suction line
How is the hydraulic suction line coming from the bottom of the rear differential attached? Does it screw in the housing? Noticed mine is leaking from that area. I would like to remove and seal the connections. Thanks for your help.

Re: 154 hydraulic suction line
My parts book says flair fittings.
Don't really know, never removed mine.

Re: 154 hydraulic suction line
It’s a npt thread into the tranny case. (National pipe taper) In some applications this hole is a drain plug. Then a flaired fitting is screwed in and the tubing goes from there. If you need the tubing pre made I purchased a complete 154 tractors tubing from hamiltonbobscubs.
For some reason I remember a tee being on the tubing there. They had a suction and return on the same tubing. I think the design changed and they put the return line on the tranny shifter cover.

I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

Re: 154 hydraulic suction line
FWIW that particular SS line has compression fitting and it always leaks a tad. Generally, I was under the tractor with the deck removed, trying to get it to seal. There isn't enough line for a do over and I never bought or made a new line. So it does drip during use-just a little. That requires me to add some fresh fluid before the next excursion. I can't say there is anything positive about a leak except new HyTran or equivalent ...nope. It is still wrong.

Re: 154 hydraulic suction line
Cutting the tubing and adding a piece of hydraulic hose with four hose clamps will work so you can fix the leaky fitting. Are you sure it’s a compression fitting. I think it’s a Parker fitting with the tapered double wall flared nut.

Re: 154 hydraulic suction line
You have to be right on this. Double flare IIRC . I didn't have the means or time when it was happening. Thought I had it done but still leaks a tad. There are some bends in the line which I stretched to give more "purchase" or pressure towards the fitting while checking alignment. Will still need a new fitting someday.
