R34 GTT Power Steering Pump

[Navoss]

Hi everyone,

I'm replacing the power steering pump on my 1999 GTT as the original one has failed.

The pump available to me is Part No: 49110-AA100, but my current one is 49110-AA000.

Visually, they look nearly identical — does anyone know if there's a significant difference between the two, or if the AA100 is compatible with my car?

Thanks in advance!

I don't know, but Nissan often supersede parts with other parts that are compatible. Using your VIN you can check here: https://www.amayama.com/en/genuine-catalogs/nissan

Otherwise, if it is not an official supersession but physically fits you would need a bit of luck for someone to post their experience, or just send it (ie, if it bolts in the right place, has the right pulley or you can change the right pulley on, and the outlets are in the right place, just use it)

Finally...unless your current pump has internal damage, you should be able to get it rebuilt (new bearings and seals) by any half decent mechanic; bearings and seals are readily available

AA100 and AA110 are supposedly not cross listed, not sure what the differences are. Most likely you're better off rebuilding what you have unless the housing is trashed by debris circulating in the system or significant amounts of cavitation.
