7308 Loader Problem

[John_Mc]

If one has two circuits #1 and 2 and number one is on valve number one and two is on valve two. If you move the lines from one to valve two and the issue goes with the lines the valve is the same and so it is the issue.

Think of it this way valve one is the boom lift circuit and valve two is the bucket curl circuit. In the move the lift valve will control the curl and the curl valve will now control the curl cylinder(s).

But in that example the issue moved with the lines, it didn't stay with the valve. If the issue is with curl not working and you move he curl lines to another valve and the bucket still won't curl, the the issue has moved with the lines, not stayed with the valve.

Yes it did meaning the same valve had the issue with both sets of cylinders so the valve is the common denominator and is the faulty part.

Also the fault now is happening on the other set of cylinders.

Good news is the valve for the TC45DA is still available, Messick's has 1 in stock. Bad news is it is $1201.96. The valve can be rebuilt according to the parts diagram, there was a complete kit available at one time. Some of the individual parts are still available.

Yes the TC45DA is available I just bought one this year.

When I replaced it I asked about the repair kit but it is the detent parts. If the valve spool(s) or body is worn it’s replacement valve time.
