Mahindra 3316HST Hyd hose routing diagram - with BH, w/o BH

[alia176]

Gents,

I know this question has been asked before but search revealed lots of noise. Hopefully these diagrams will help out others.

Can someone confirm the hyd hose routing in the attached two diagrams? Did I get the routing correct for connecting a BH and normal operation w/o a BH attachment?

With Backhoe


Normal operation, w/o BH

Does your BH have a PB port , otherwise, the BH has three lines to and from the BH?

PB from the loader would feed the BH.

You diagram appears to be correct if your BH has PB.

 

[alia176]

Yes, the BH has the three ports as illustrated: P, PB, T.

The T from the FEL would tee into the T at the hyd block.

The T from the BH would tee into any return hose.

Ok, thanks for the confirmation on the diagram.

As a FYI, the Mahindra 3316HST doesn't require any Tee's for the installation of the Mahindra 3720B backhoe. I think Tee's were required for the 3720A Backhoe installation but don't hold me to it.

I'm on a project to re-do the hyd hoses on my tractor so that connecting/disconnecting is more elegant than the current setup. I'm going to set it up similar to the 3720A BH hose routing and the cool QD's at the rear of the tractor. I just wanted to understand, on a generic level, the flow of the hyd fluid on a typical tractor.

Thanks again for the help!

That T line from the BH has to either go to a return port tee or a dedicated tank port on the tractor.

Ahh, ok. When you say T, you mean Tank line. I confused that with a Tee (fitting)! Sorry about that.
