BLAST Go Kart Forward Reverse Gear Box Fits 2HP - 11HP Engine 41P 10T or 12T TAV30 - ONLY Works with 30 Series Torque Converter

The listing said it only works with 30 series torque converter, so I bought on of those also. The input shaft is 1/8" smaller than the driven pulley bearings, so they will need to be replaced. The driven pulley will not fit on the input shaft as is. The shaft is a thousanth or two too large. The #35 sprocket won"t fit on the output shaft.

Works as designed. Could use some much better instructions.

No Install instructions. The cables are too short and poorly manufactured to work with system. Be prepared for a lot of customization. It does work but not any easy add for the series 30. The gearbox seems good but the cables, shifter, etc is pretty sketchy.

I having now thank you

This gearbox is not meant to be installed tipped way back like it is in the seller photos. This gearbox is meant to be installed outside the engine, not under it. It is a wet gear box, and the input shaft will not get any lubrication if you mount it like that.Mount the gearbox off to the left of the engine (looking from the back), and the input and output shafts will be correctly placed to not need a jack shaft. However, if your axle is further back than the engine/transmission like the one reviewer's photos, then you will need to mount it tipped up, but its not a good orientation.
