Can I change my controls on my BH92 backhoe?

[LD1]

1. what is causing this noise.
No idea without a sound clip or video.

2.Could the noise be caused by changing over to iso controls.
Unlikely. If the changeover was done correctly....should cause any other changes to the pump or cause any "noise".

3.Can the leak cause the pump to starve for fluid even if the oil level is fine?
Yes its possible. If the leak is on the suction line feeding the pump or something

4. The extra cylenders on the backhoe of course need extra oil. Is the hydro reservoir on the tractor ample to supple this extra oil demand that the backhoe cylinders require?

Yes they require more fluid. But once that backhoe is installed and all the cylinders purged and filled.....top tractor back off and should be fine. Then the only amount of fluid required is alot less and the tractor should hold about 10-12 gallons anyway. Which should be plenty. Sure the level will fluctuate.....but nothing to put it in danger range.

Not sure what "pin" is leaking under the tractor. If it is the cotter-pin that is just in the bell housing hole it sounds like an input seal to the transmission and you will need to split the tractor to repair

Thanks for your info. Yes the pin that I was referring to is the cotter pin that is just in the bell housing hole. I think you are right. The tractor will have to be split and seal replaced. I have a loader and the backhoe frame. Would you say it is a 10 hour job?

Mine is 2020. Three or 4 years old. ISO the left lever is to run the stick and the right lever runs the boom. Boom being the closer to you.

Well that is not what the pictures above show. My left lever (foward and back) runs the boom (closest to the seat) and right (forward and back) runs the dipper. Again, that picture is ISO.

The only thing missing from the pictures is the seat for the BH position, maybe that is why the controls might be seen opposite. I am assuming that the bottom of the picture is the position for the BH seat and you would reach (up) to grab them?

Have no idea your shop setup, tools, or capability.

Half a day for someone who knows what they are doing on an open station.....up to 2-3 days if you have no idea whats going on.
