Can a quart of oil be added to the Primary Chaincase or Transmission when SYN3 is not available?
If SYN3 is not available and addition of lubricant to the Primary Chaincase (Evolution 1340 and Twin Cam 88) is required, the first choice would be to add H-D Primary Chaincase Lubricant. Although H-D Primary Chaincase Lubricant is compatible with SYN3, we suggest the mixture of the fluids be changed as soon as possible. If SYN3 is not available and addition of lubricant to the Primary Chaincase and Transmission (common reservoir) for Evolution XL and all Buell models is required, the first choice would be to add H-D Sport-Trans Fluid. Although H-D Sport-Trans Fluid is compatible with SYN3, we suggest the mixture of the fluids be changed as soon as possible. If SYN3 is not available and addition of lubricant to the Transmission (Evolution 1340 andTwin Cam 88) is required, DO NOT ADD H-D Semi-Synthetic Transmission Lubricant as the two lubricants are NOT compatible.
