Long Notes
This is the Later Version of the 13470. The Bottom Mounting Hole on This Version is Threaded (Threaded Bushing). A Hex Mounting Bolt (Size M10 x 1.5), Washer, and Nut Could Be Included in the Box With the Unit (If Supplying a Unit Without the Threaded Bottom Bushing) to Replace the Unit With the Threaded Bushing. It Appears That BMW May Have Gone to the Threaded Bushing Because of Heavy Rust Build-Up and Corrosion on the Unthreaded Unit Rear Mounting Area (With Seperate Nut), This is What Rebuilders Report They See on the Cores Being Returned. |
