Warranty Card

BAKER Drivetrain Limited Warranty
All BAKER products come with a limited warranty, but some small products do not come with a warranty card. The statements below state our warranty, warranty provisions and return / exchange policies. If your product does not ship with a warranty card the warranty statements are printed on the invoice in the lower corner. On the right you will see a image of the warranty card; if you need to download and print this off click on the link located at the bottom of this page.


Limited Warranty
NOTE: Warranty card must be returned within 45 days of purchase for your warranty to be valid.


BAKER™ transmission assemblies, transmission kits, primaries, and oil pans are guaranteed to the original purchaser to be free of manufacturing defects in materials and workmanship for a period of 5 years from the date of purchase or up to 50,000 miles – whichever occurs first. BAKER™ clutches, kicker cover kits, belt drives, F6F kit, reverse systems, covers and accessories are guaranteed to the original purchaser to be free of manufacturing defects in materials and workmanship for a period of 2 years from the date of purchase or up to 24,000 miles – whichever occurs first. If the product is found by BAKER™ to be defective, such products will, at the option of BAKER™, be replaced or repaired at cost to BAKER™.


In the event warranty service is required, the original purchaser must call or write BAKER™ immediately with a description of the problem. If it is deemed necessary for BAKER™ to make an evaluation to determine whether the transmission assembly or transmission kit or accessory is defective, the entire transmission assembly, whether originally purchased as an assembly or kit, must be properly packaged and returned prepaid to BAKER™ with a copy of the original invoice of purchase. If after an evaluation has been made by BAKER™ and a defect in materials and/or workmanship is found, BAKER™ will, at BAKER™ option, repair or replace the defective part of the assembly.


Additional Warranty Provisions
NOTE: Limited warranty does not cover labor or other costs or expenses incidental to the repair and or replacement of BAKER™ products.


This warranty does not apply if one or more of the following situations is judged by BAKER™ to be relevant: BAKER™ OEM transmissions; (these are subject to the OEM manufactures warranty only), Improper installation, accident, modification (including but not limited to use of unauthorized parts, transmission oils or lubricants), racing, high performance application, mishandling, misapplication, neglect (including but not limited to improper maintenance), or improper repair.
BAKER™ shall not be liable for any consequential or incidental damages arising out of or in connection with a BAKER™ transmission assembly, transmission kit, component or part. Consequential damages shall include without limitation, loss of use, income or profit, or losses sustained as the result of injury (including death) to any person or loss of or damage to property.


BAKER™ transmissions, transmission kits and accessories are designed exclusively for use in American V-Twin motorcycles. BAKER™ shall have no warranty or liability obligation if BAKER™ parts are used in any other application.


If it is determined that a BAKER™ product has been disassembled during the warranty period for any reason, this limited warranty will no longer apply unless you were instructed to do so by a BAKER Drivetrain technician for diagnostic purposes.

Following the demise of Big Dog Motorcycles as a motorcycle manufacturer, BAKER Drivetrain informs all current Big Dog owners and all dealers (ex Big Dog or not) that their service parts and upgrades will continue to be available directly for all Big Dog Makes and Models. Whether you need an inspection cover, replacement o-ring, top cover or want to upgrade from the stock chain primary to an open belt drive, we got these parts in stock.


BAKER Drivetrain accepts new dealer applications from those thinking they will have to work on Big Dog motorcycles ( Call 1-877-640-2004 to set up your dealer account for dealer web access and price lists) BAKER manufactured the whole drivetrain for 2005-10 Big Dog models. The center distance of the primary drive is based on our DSSC and is not common with a Softail. We used our knowledge of the factory system to develop a Synchronous Belt Drive. The pulleys are hobbed from stainless steel blanks for durability and corrosion resistance. The structural integrity of the stainless steel clutch pulley significantly reduces that loose tappet rattling sound that some other belt belt drives make when the clutch is disengaged. The indestructible pulleys are driven with a large 2.4″ belt and coupled with a radial ball bearing suspended outside the bearing support.


Other popular parts offered for Big Dog motorcycles are: BDM Chrome Inspection Covers, BDM Bearing Door Chrome, BDM Chrome Cast Top Covers, BDM Chrome Derby Covers, BDM Pulley Cover Actuator Cap, BDM Chrome Pulley Cover and all Big Dog Specialty Tools (pulley, bearing, gear set installation and removal)
