Backhoe JD400 Reverser Valve tubing

phuse71 · Jul 1, 2014

I have a JD400 67' and I removed the reverser valve, in doing so a long (appro 12") tube came loose and I cant see where it plugs into. My manual says it goes to the reverse clutch but I cannot get my hand/arm in to feel for the hole. If anyone can give me a ball park area where the tube will go to at least I will have a chance. Photo would be better. I have tried a cheap camera scope but did not help. I can send photo via email of the tube and the reverser opening in the transmission.

Here's the parts schematic for the lines. Sorry but it's been too long since I've seen the inside of trans to give any more assistance.

Look at part KEY 8 in this drawing. At approximately 4 o'clock position are two ports. One is for the forward clutch pack, the other for the reverse brake pack.
I am not sure which is which, but hopefully you only will have one missing a tube. Since I have a 50/50 chance, I'll guess the lower is the reverse brake.

Thankyou for the help, I will try again once it stops raining here as the Backhoe is outside.
