Cub Cadet 149 - hydro tube question
 

So I have a 149 where the hydroline continued to leak. So I bought the suggested cub cadet 927-3008 and didn't see a gasket for the line running into the 5/8 nut to 7/8 tube. Anyone have any hints or ideas of what goes between the tube and the nut?

First, welcome to OCC.... :Welcome2:

There is NO gasket to that connection. There is a brass "compression sleeve" that tightens down against the tube to seal it. See attachment.

On my 149 I've got the tube style pictured on the left. Does this mean my original tube was replaced?

It looks like both style tubes take the same compression fitting where they enter the sump -- is that correct?

It does NOT matter the style or shape of the tubing. The brass sleeve remains the same.

Maybe the brass ferrule is worn, distorted, or misaligned. Teflon tape on the threads might stop a small leak.

Tape or sealant on the threads would do no good as the sealing is done by the ferrule.
A new ferrule can be had at most better/larger HWD stores.:beerchug:

The OP didn't say the new suction tube was leaking, just that it didn't have an obvious seal. If it's missing the ferrule, that's all that's needed. If it already has the ferrule, just put it on and snug it up. Good.

The ferrule could be worn or misaligned and therefor not properly seal. Be sure to inspect the ferrule and mating surfaces.

Over the many years, I have seen Ferrule's that were crushed beyond recognition, some actually split and a multitude of states of condition.
They are one of my least liked fittings.
In the early years of automobiles, they were popular,and in various configurations.
One of the things I don't like is if over tightened they can actually crush the tube they are installed on, causing it to not seal again,also making them near impossible to remove to try to replace.
In the position of this discussion, the suction tube is easily relocated/damaged/bent, when it came in contract with something ran over or high centered on a rock or something similar, and it leaks as we know.
hopefully a minor tightening will cure the problem.:bigthink:

So the ferrule wasn't included and my original tube didn't have it, hence why it was and still is leaking.

I'll have to get one and place it on. Thanks for the tip. You'd think cub cadet would've included that with the tube purchase free of change. I'll post an update once I get it installed. Thanks again everyone!
