toolcat 5600 diff lock.

[ls1chris]

so new here found out something cool i have not seen anyone ever post anywhere about the toolcat diff lock.
i recently went to my local dealer to buy what was needed for my front diff to ad a locker to it. i checked the sin and part numbers on the front and rear diff only to find out the part number is the same! . the parts counter at the bobcat dealer also confirmed that there is NO different part number for a front or rear complete differential assembly and put me onto the bobcat Tech phone number. that fellow "Larry" dig some digging and got back to me 2 days later to confirm the same thing dealer parts guy stated.
so pulled the 5600 into the garage and put it on jack stands. i pulled the plug out of the front diff and used a leakdown diesel ring tester with guage i modified to fill that sucker up with air to see if it would lock up. and it didn't, i put 160 psi of air in there and nothing. but it kept the air in there overnight, didnt lose a pound.
back to bobcat few days later getting filters ect and ordered a service shop manual.
well it came today and had confirmed what i have been suspecting. on page 40-20-20 of my manual it states in bold black
" NOTE: the front and rear axles are equipped
with a locking differential. The locking differential is only used in the rear axle. The disassembly of the both axles are the same."

further digging on page "A" of the hydraulic legend sheet states " item 23- differential lock valve 218-363 PSI"
well at a minimum 218 to engage , my compressor would have never moved that piston to put enough force on the locking coupler to lock that diff up.
going on holidays next week but when i get back i am going to buy
1- the rear diff-lock supply line and lock fitting
2- a "T" fitting ( for on the 12v diff solenoid)
3- a "3 way" toggle switch , ( so i can bypass the original hold down POS one that is in there and run a fused / keyed hot so i can engage , front/rear/both when i want in 2ws or 4ws as i am freaking tired of getting stuck in the muck!
i will post pics of the pages shortly.
Chris.

not actually sure if i can post a pdf of that here, if someone knows pm me and let me know? not sure if i want to get banned of my first thread. maybe a mod can pm me?
if anyone knows abit about the hydraulic side, if i put a splitter T would you not think once lines are bled out it will keep the same pressure as if it was only one diff? there is no return on this, turn it on, it gets "pilot pressure" turn it off and the line pressures down.

Sounds like a good plan, the T should work in this case since there is no flow, just pressure.

I don't know about posting a PDF, but it may be possible.

You can post a weblink to the pdf.

I know I'm interested.

When I get home I'll try to figure out how to upload to a file hosting and post a link. Some forums are funny about uploading copyright material

With a T, would you only be able to engage both diffs at once and not independently?

May I ask which series Toolcat you have? I'm assuming that a 2006 is a 'C' series? I ask because I would be very interested if it were possible on my 'B' series.

old thread, but I too am interested to see how this turned out

you can lock both axles but the issue is if you turn the axle is locked, one of the wheels have to slip, I could see a Tee with a valve allowing a momentary lock of the front axle when driving straight but word of caution if turning
