you would be right edward
this big monster is not listed in mfca's database. The largest truck they list is a V330C.
As far as this V925 i'm sure there is media for this truck somewhere but as you said this was built back when cat was building their lift trucks and not farming it out to someone else so as for mfca having it? they might but he would have to ask for it.
Or if there is some remote shop somewhere that has worked on these at some point they may have a manual handy but locating them might be a challenge. But if he got with the dealer that sold the truck they may be able to find out about a manual and sell him one.
and yes, knowing the symptom may help us help him figure it out. ;o)
I've worked on big trucks and the P20000 has air over hydraulic on it... maybe there are some similarities between the two.
