Hose replacement on a 642

[Cyclone Ranger]

I need to replace the drive motor hoses on a 642. Can someone tell me what the OEM spec for these hoses is? I current have a mix of R1 and R2 hoses. Since clearances are tight I'd prefer not using R2 hoses unless they are required.

They should be 4 wire from memory, they need to handle the 5,000PSI the pump will generate. Don't go smaller or you risk bursting one.
Sadly they are hard to bend, but its the price you pay for handling the pressures. You will know for sure when it comes time to replace them and you cut the old hose.

I bought every hose on this machine and I was going to make them but I was surprised that the price wasn't to bad.

I'm beginning to think you snuck your Bobcat out of the factory a piece at a time in your lunch box.

And a view from the front:

Notice the interference between the motor hose and the linkage on the right side of the picture. Do others have this issue?

I see it, I looked at mine and it does not touch. But theres a looks to be a 30degree fitting at the motor. Looks like the line should be shorter.

What did the hoses cost and do you have a list of part numbers? I need to change mine this spring.

I would like to put in another shameless plug for ferryinc. I continue to be impressed with the quality of their hoses and staff. They can't look up Bobcat part numbers but if you have a hose length, size, and ends, they can make them for you and ship out same day. Their hoses and ends are all Gates. They also have a wide assortment of plugs and caps. Their number is 716-684-1706. Ask for David at extension 103.
