Working my way through a basket case 94 motor and trans I picked up last night. I am trying to learn the tranny gear sets and have a question. I have a 32 tooth 1st gear countershaft gear and a 30T (35763-89a) gear 4th gear mainshaft gear. In looking at part numbers and tooth counts, the CS gear is right bu the mainshaft 4th gear should be 37T (35773-94) - these gears look similar - they have a shoulder offset. Any tranny experts out there, if yes, I could use your help. This is my first Evo sporty, but I have built and owned many many ironheads since 1974. ferg

 

Well - the superceded part number 35773-94 is a 37 tooth sprocket - but the 35763-89a part number is a 30 tooth - go figure - so I have the right gears in the bucket - now I have to build this tranny which should be fairly easy - same principles as the ironheads but with a drum shifter
