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 off 2) Remove spacer ring from driven pully housing (silver, drivers side). Place on drive shaft next to existing brass spacer bushing 3) 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 place 5) 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 fit 8) 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/belt 10) Use some sort of "L" bracket to secure shifter in appropriate position being sure to attach cables to it before install 11) 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. Review: So far so good. - 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. ## Features - ▶Gearbox Kit 30 Series -This forward reverse gearbox is suitable for go-karts,utility vehicles and other applications with engines up to 14HP and # 35 chain 12T and #40/41/420 chain 10T (Both sprockets included).Please note only use on 30 Series - ▶Standard Adaptation Parameters-Shaft Size: 5/8" with 3/16" keyway; Gearbox Speed: 5/13 of the Clutch speed; Shifter Cable Length: 1540mm ( 5' ) ( 60'' ).Forward Ratio: 1:1:3,Reverse Ratio: 1:2:6 - ▶Complete Accessories-1x Forward / Reverse Gearbox with 3/16" Keyway;2x Mounting Plates;1x Shifter Disc;2x Shifter Cable;1x 10T and 12T Sprocket;1x Shifter Assembly - ▶Product Use-This product was filled with oil before leaving the factory,when the oil is used up,it needs to be filled to half of the box,and this go-kart gearbox is use GL-5 gear oil - ▶Three Shift Modes-This kit has three shift models: forward,reverse and neutral,which is for more convenient and easy operation.Made of high-quality metal,features with durable and lightweight for a long use life.Please contact us if you have any questions ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083FVDF7R | | Best Sellers Rank | #156,731 in Automotive ( See Top 100 in Automotive ) #39 in Automotive Replacement Torque Converters #967 in Automotive Replacement Transmissions & Parts | | Brand | maXpeedingrods | | Customer Reviews | 4.2 4.2 out of 5 stars (315) | | Date First Available | January 3, 2020 | | Item Weight | 12.35 pounds | | Item model number | YW65 | | Manufacturer | Waverspeed | | Manufacturer Part Number | YW65 | | Product Dimensions | 7.87 x 7.87 x 7.87 inches | ## Images ![maXpeedingrods Go Kart Forward Reverse Gearbox Kit 212cc 30 Series - Image 1](https://m.media-amazon.com/images/I/71SB7+EU3lL.jpg) ## Questions & Answers **Q: How long are the cables?** A: 5’ **Q: What is the total length of the shaft with thread's** A: The total length of the shaft with thread's is 27mm **Q: Since the engine will be shutting off whenever i let off the gas (golf cart), can i use the sprocket as the input? then, can use the original cvt dif.** A: No. The sprocket is on the output shaft. The output shaft cannot be used as an input shaft due to the internal gearing arrangement. **Q: What's the warranty on this** A: Not sure about the warranty. Warranties differ from one manufacturer to the next. From previous experience, most manufacturers only provide a limited warranty for maybe a 30 day period. You should contact the seller for this information. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works.......and it's awesome *by S***M on March 22, 2023* Like many others here, installed on a Coleman KT196.
