Dose anyone know the size of a big end bearing in a promax RG5410a

[Snowmanbob]

Hi chaps I’ve got a promax RG5410a knocking it’s arse off from the big end ball bearing
And was wondering if anyone knows the size of the bearing so I can order one and replace it before it jumps off the roof and would it be better to fit a bearing with rubber seals or metal, or will the refrigerant wash away any grease in the bearing no matter what seal ,



Thank you clever peoples

You probably need a repair kit, not just one part
