clutch 307 HDI 90 CV

Good afternoon. I am changing the clutch of the 307 SW of 2007. After removing millions of screws, battery support, exhaust, diesel and air filter, launched, left wheel suspension, and others the change does not come out, it may be that it is that some path of the envelope is left by the part of the oil pump, because it is apparently all loose but from the part of the pump does not take off. Thank you very much in advance.

If it is a 1.6 HDI you have to remove the catalyst/ particle filter and all the thermal screens, because it carries a screw behind.
