Hello dear
I have this dozer CAT year: 1986, model D4H, serial: 08PB00451, série II
We have recently bought this dozer, upon couple hours I noticed the overheating in the transsmision, we have decided to replace the next parts,
3T8316 planetary transmission sn 1CE514-1675 :
6T8687 DISC FRICTION (5)
6Y7965 DISC FRICTION (17)
9P6799 PISTON CLUTCH (1)
3P7019 SEAL METAL (1)
9P7101 PLATE CLUTCH (4)

9P3041 spring inner (1)
7G4842 spring outter (1)
Control Valve Transmision Hydraulic 8P8984:.
3D2824 Seal o-ring (1)
6Y2349 Connector Special (1)

So after done the service and those parte replaced, we have placed in service and after 30 hours, again the temperature to continue overheating,
