Port bypass
 

I have a PORTED hydro pump and want to temporarily bypass the ports, So I can use the tractor while repairing and upgrading the lift systems.

Can I just loop the two ports w/tubing?
if so
What diameter would be best 3/8"or 1/2"?
Would Compression or Flair fittings be best?

Thanks

I have pretty much the opposite. A ported pump that has never been used from a 129. Going from opposite of what I have to do, you can remove the sping and cone on the side of the pump and then just cap off the hoses.

Think backwards of this, lol. Page 9 is what I think you would want. http://ccmanuals.info/pdf/169%20Hydr...On%20Setup.pdf

AHHH, GOT IT....I stood on my head to read it:biggrin2:

so you just remove spring and cone from charge pump relief valve (on the side right?) and plug lines??

Yea If I'm reading correctly. It looks like some came like that and you could add hydro lifts.

lol

Its saying to swap the springs around. Not sure if you have to worry about that or not. But my charge pump spring and cone are missing completely so I think that is so it can just bypass inside. I was looking around for a hydraulic circuit of the pump innards with no luck the other day. I thought I saw one once. I have to search some more so I can understand it all better.

it cant wreck anything by looping the the ports together though right. because i dont want to take my spring and cone out and loose them lol.

That's kinda what I would like to know also. I seem to lose important things like that too.

Larry, I thought you would need the charge pump spring? how does yours work w/o it?
