from what I understand, type 46 hydrolic fluid is a compatible substitute, and is fine for testing and flushing the system. it worked in my 79TD for over a year, (and may still be working... I no longer have the car) and it's what I am using in my sagging but 83TD until I can get the pump rebuilt (PM soon to be sent!)
do you know if the 87TD uses the same fluid and has the same Valve kit for rebuild? not that my 87TD has ANY issues, but I plan on keeping it for a LONG time, so "be prepared"
