Otherwise, the belt may pull the driven open too soon making the spring seem weak. The balance seems to be fine on both clutch and driven, no wobbles noted. I updated the three springs in the clutch driver to be the comet red series so that the engagement is at 2000 rpms instead of 1600 rpms. Everything is working well. ## Features - 5/8" Clutch 6" Driven 30 Series Torque Converter: Part Number(Comet 219457a), 6" Diameter, 5/8" Shaft Bore, 8hp Max - 30 Series Torque Converter Driver Clutch, 3/4" Bore, Replaces Comet 219552, 5957 - Replace Part Number: Comet 219552, Manco 5957, Yerf Dog Q43201W - Perfect replacement driver clutch for small engines with up to 7 HP, Fitment: Mini Bike, Go Kart, Lawnmower And Many More - Brand new high quality 30 series asymmetrical driven clutch with 3/16'' key way and 3/4'' ID hole ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07N7VBQSV | | Best Sellers Rank | #74,283 in Automotive ( See Top 100 in Automotive ) #84 in Powersports Clutches #626 in Powersports Drive Train Parts | | Brand | BLACKHORSE-RACING | | Customer Reviews | 4.2 4.2 out of 5 stars (649) | | Date First Available | January 29, 2019 | | Is Discontinued By Manufacturer | No | | Item Weight | 7.47 pounds | | Lift Type | manual | | Manufacturer | blackhorseracing | | Manufacturer Part Number | HM0819 | | OEM Part Number | Comet 219552, Manco 5957, Yerf Dog Q43201W | | Package Dimensions | 11.93 x 8.07 x 4.76 inches | ## Images ![30 Series Bore GO Kart CVT Torque Converter 3/4" Bore 6" Diameter Driven Asymmetric Go Kart Mini Bike + 5/8'' Driven Clutch Comet Kit + 725 Belt - Image 1](https://m.media-amazon.com/images/I/71wJLYZntkL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Whats the stall on this before the clutch kicks in?** A: Depends on allot of things.

Took me about 10 minutes on the internet to find out why. These drive clutches need to be taken apart and sprayed with a dry molly or graphite spray on the roller surfaces and rollers before use. I had the same problem as everyone else before doing this. I think even Comet has instructions to do this as part of servicing them. Not sure why Blackhorse doesn't do this upon assembly? The only complaint I have, is the clutches wobble slightly do to the clutch halves being distorted in the stamping process when they are made and the belt size provided does not work with the recommended spacing at 9.75 center on center. I had to purchase a Comet 203788A belt. Also, if you plan to run the driven clutch (large diameter) with the spring facing away from the engine you will need to install a yellow reverse wound spring. From someone who was new to this the picture for the listing shows it pictured for a reverse spring which it doesn't come with. If you plan to run it without spending money on a reverse spring the driven clutch needs to face the opposite from what the picture shows in this listing. Hope this review helps. ## Frequently Bought Together - 30 Series Bore GO Kart CVT Torque Converter 3/4" Bore 6" Diameter Driven Asymmetric Go Kart Mini Bike + 5/8'' Driven Clutch Comet Kit + 725 Belt - BLACKHORSE-RACING 3pcs 30 Series Go Kart Drive Belt Replaces Manco 5959 / Comet 203589 - 3PCS 30 Series Go Kart Drive Belt Replaces Manco 5959 / Comet 203589 Durable Trorque Converter Belt --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/115962424-30-series-bore-go-kart-cvt-torque-converter-3-4](https://www.desertcart.vn/products/115962424-30-series-bore-go-kart-cvt-torque-converter-3-4) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-17*
