Do they use a bigger bearing or can they use stock?

Setback or standard? The Setback mag has 2 different bearings, same as the GP800.

Does anyone have a Yamaha part number for a 5205 bearing used in a setback mag pump? Thanks in advanced.

Try @JetManiac ,he may even have what you need in stock

 

[NathanMoore]

@Sanoman I've ordered from Jetmaniac before when I'm home, but right now I'm in China, shipping/customs is crazy from US. I'd like to find it here first if I can. I have a good source of OEM Yamaha parts, but need a part number to give them.

Yamaha used the 5205 double row bearing (93305-205U0-00) in the midshaft of WB1. Here, Yam retail is $66, generic about $16. If you must have the Yam bearing, get it and just remove the 2 seals with a pin or pick. Are 5205 bearings not available where you are?

 

[NathanMoore]

@augustaf Thank you for the part number.

Doesn't have to be Yami, just didn't want a chinese knock off bearing. Just too many Chinese knock offs and can be hard to know for sure if your getting a genuine imported product or not.

Here in the US I stay away from bearings which are not marked with the manufacturer's name- that has come to be quite a plague in the industry.
