maXpeedingrods Go Kart Forward Reverse Gearbox Kit 212cc for 2HP-13HP Engine 4 Stroke Only Works with 30 Series Torque Converter 3 Shift Modes #35 Chain Go Karts Accessories Go Kart Transmission

Like many others here, installed on a Coleman KT196. If you have any familiarity with a welder it is pretty straightforward to install. Took about 3-4 hours with a good deal of that dedicated to explaining what I was doing to a 6yr old. If I get motivated I will update with pictures, but basically the below sums it up:1) Remove existing clutch and driven pully from Kart. Cut rear protector bar off2) Remove spacer ring from driven pully housing (silver, drivers side). Place on drive shaft next to existing brass spacer bushing3) use two 3" long section of angle iron (of appropriate thickness). Drill hole for 8mm bolt towards back top of each (for mounting of transmission). I bought a longer bolt (120mm) and used a 1" spacer between the trans mount (lower bolt hole) and the passenger side piece of angle. This allowed for a better position in welding to the existing motor mount structure.4) Align drive sprocket with trans sprocket. Tack into place5) Attached upper adjustment saddle (the gold "U" with a threaded rod sticking out.6) Place a sleeve over this rod and, one aligned, weld to the top of the sleeve that previously held the driven pully shaft removed in step 1. You will need a longer bolt to re-attach the pully later (can get at hardware store)7) Confirm chain length with new section of #40 roller chain. Adjust tack positions as required for adequate fit8) Weld everything in place. The center distance between the drive and clutch shafts should be around 10 3/4"9) Use belt 203597A (longer than factory). Attach chain/pullies/belt10) Use some sort of "L" bracket to secure shifter in appropriate position being sure to attach cables to it before install11) run cables back to trans, attach, make final adjustments.12) (optional) weld rear protector bar back on as you please. This makes lifting the rear of the kart soooooo much easier.Can be a first-time fab project, but it will take awhile. Pretty straight forward if you have ever had to adapt two things together on a motorized vehicle that were never intended for such. Makes the kart noticeably faster. Took all of five minutes for above noted 6yr old to test it out after running full speed into a tree.

It's a nice reverse kit love it

Works great exactly what needed

if you have read any other reviews, you will be aware that there are no instructions of any kind sent with this. If you are comfortable fabricating, it is a easy task. I had some questions about what oil to use, and how much, also what angle could this be mounted. I had to guess on most of those answers.otherwise, it seems to do what it is advertised as.. It gives a nice forward and reverse, nice shifter, nice cables, and it seems to be pretty robust, although I am only using it on an airplane tug, so dont know how it will act on a go kart or similar application.

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
