R3400 Anglgear Right Angle Bevel Gear Drive, Universal Mounting, Single Output Shaft, 3 Flange, Inch, 1" Shaft Diameter, 1:1 Ratio, 7.04 HP at 1750rpm

I purchased this product for my company for a hand powered drive shaft for a mechanism we produce.The gear inside feels very solid, no measurable wiggle in the gears (at least by my hands turning the shaft).The unit itself can be cleaned/lubricated/disassembled by removing a c-ring on the non shaft end, although i have not done it.Mounting holes are solid. overall construction feels good.If you need a CAD file for the gearbox... it can be retrieved here:[...]you just need to put in your email address. It's not third party... it is the manufacturer's website.Greg
