The hydraulic pump at the rear of the PTO keeps blowing the seal between the two units. The seal on the pump has been replaced twice and has failed twice. In frustration, I sent the pump to Oregon to be rebuilt. I just had it re-installed and the seal blew again! Beaver Service says it could take several months to order another pump from Europe. Any thoughts? In addition, the engine is severely overheating. I'm sure these things are somehow connected. The coach is an 05 Monterey with a C9.
