{"product_id":"v-twin-51-1040-replica-1936-knucklehead-frame","title":"V-Twin 51-1040 Replica 1936 Knucklehead Frame","description":"Replica frame is an authentic reproduction of the factory style with 13 brazed joints. The 28 rake neck angle will accept inline spring forks. Features 1 inch down tubes with weld on side car mounts specific to the 1936 model only!\n\u003cp\u003eThe V-Twin 51-1040 Replica 1936 Knucklehead Frame fits the 1936 Harley-Davidson EL. It accepts a Knucklehead or Big Twin Flathead engine with a 3-speed or 4-speed transmission. The frame is new production with 13 brazed joints designed to replicate the original construction.\u003c\/p\u003e\u003cp\u003eIncluded frame components include the seat post, brake cross shaft, rear axle assembly, transmission plate, and motor alignment plate. Cross shaft bushings, a toolbox mount, and grease fittings are installed. Forged components include the neck, front and rear engine mounts, yoke, and rear axle plates. Brazed components include the top motor mount, front tank mount, sidecar loops, footboard mount, transmission strap, center post strap, rear fender crossbar saddles, oil tank mount, and upper rear frame bars at the tank tube.\u003c\/p\u003e\u003cp\u003eFor the original rear axle plate appearance, the rear brake slot on the left side must be cut out at the front; this area is closed for the builder to remove as desired. The seat post and cross-shaft bushings may require additional reaming for proper fit, and some holes may require slight reaming or filing during assembly. The Knucklehead frame requires clamp-on coil bracket kit 49-0099. The horizontal frame crossbar uses 7\/8-inch outside-diameter tubing. This replica frame has no stamped serial numbers; V-Twin supplies a bill of sale referencing part number 51-1040.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFitment: Fits 1936 Harley-Davidson EL\u003c\/li\u003e\n\u003cli\u003eEngine and Transmission Compatibility: Accepts a Knucklehead or Big Twin Flathead engine with a 3-speed or 4-speed transmission\u003c\/li\u003e\n\u003cli\u003eConstruction: New-production frame with 13 brazed joints\u003c\/li\u003e\n\u003cli\u003eIncluded Components: Seat post, brake cross shaft, rear axle assembly, transmission plate, and motor alignment plate\u003c\/li\u003e\n\u003cli\u003eInstalled Components: Cross shaft bushings, toolbox mount, and grease fittings\u003c\/li\u003e\n\u003cli\u003eForged Components: Neck, front and rear engine mounts, yoke, and rear axle plates\u003c\/li\u003e\n\u003cli\u003eBrazed Components: Top motor mount, front tank mount, sidecar loops, footboard mount, transmission strap, center post strap, rear fender crossbar saddles, oil tank mount, and upper rear frame bars at the tank tube\u003c\/li\u003e\n\u003cli\u003eAssembly Notes: Seat post and cross-shaft bushings may require further reaming; some holes may require slight reaming or filing\u003c\/li\u003e\n\u003cli\u003eFrame Details: Horizontal frame crossbar features 7\/8-inch outside-diameter tubing\u003c\/li\u003e\n\u003cli\u003eIdentification: No serial numbers are stamped on the replica frame; a bill of sale references part number 51-1040\u003c\/li\u003e\n\u003cli\u003eAccessory Items: 51-1941 - Replica Knucklehead Frame, 51-1939 - Replica HM Knucklehead 28 Rake Frame, 10-1350 - Replica 74 Knucklehead Long Block Natural, 51-1046 - Chrome Front Engine Bar\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\nHarley Davidson EL 1936\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eUOM: EA\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCountry Of Origin: TAIWAN\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eOEM Cross Reference: 2801-36\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003e\nSuggested Items:\n51-0522 - Rear Frame Engine Mount and Front Transmission Mount\r\n27-0664 - Footboard Tabs\r\n10-1288 - Bronze Seat Post Bushings\r\n49-0271 - Parkerized Seat Post Assembly\n\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003e\nAccessory Items:\n51-1941 - Replica Knucklehead Frame\r\n51-1939 - Replica  inchHM inch Knucklehead 28 Rake Frame\r\n10-1350 - Replica 74 inch Knucklehead Long Block Natural\r\n51-1046 - Chrome Front Engine Bar\n\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eTech Notes: Knucklehead frame requires purchase of clamp on coil bracket kit #49-0099.
