maXpeedingrods Go Kart Forward Reverse Gearbox Kit 212cc 30 Series

No instructions but I was going off the reservation anyway, it needed a bearing on the end of the 5/8 input shaft, too much torque. I'm using it on my golf cart, electric to gas conversion with a 17.5hp motor, switched everything to 40 pitch chain, shifts good so far, I mounted it with the shifter on top, its puking gear oil because its over filled but im sure that will figure its self out eventually.

So far gear box preforms well... It's built durable ..I use it for extensively modifyed atv with industrial engine to do snow plowing with currently relentless winter.

This worked great for our custom go kart.

It's a nice reverse kit love it

i think the gearbox will be ok but it needs to be helped!!!! people removing TC back plate---bad for gearbox!!! too much long torque stress on the end of the input shaft--- this makes the white metal housing take all the grunt---we all know about white metal dont we!? secondly the tc backplate keeps the 2 pullies the right distance apart taking the linear [pulling on the belt] torque from the engine. 3 if you dont use a tc then put a pillow block on the end of the input shaft--again taking the torque OFF OF the gearbox housing. shifter wheel bad casting!! MINE came almost empty of any oil----hope your all filling it up b4 use. hope this helps the blowups/life increase for sure i will give it a 3of 5 untill proven 5 if it lasts with this help i will get pictures soon for a 4 track snow sled puller 13 horse honda replica engine
