I am stuck with Precombustion chambers part number for mine machine. I use european catalogue and cant find there engine arrangement 6A5546 for a 3304 engine model 48V1-48V1039
I found 8S3970 for 6A5545 or 5S-6795 which looks not excatly like in the machine now (attached photo). Maybe someone have ideas about the number I need, 5S-6795 vs 8S3970?
