theputz Posted January 16, 2013 Report Share Posted January 16, 2013 Hey, In the process of doing a 421 serval and starting to slowly build a pile of parts. For those that are experienced Banshee rebuilders what should I be replacing while the motor is apart. I see things like water pump bearings, idler gear bushings and so one. Should I just replace as needed or are there some ones you always replace? My motor is not that old or have that much wear but I dont plan on pulling it apart again for some time. thanks Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted January 16, 2013 Report Share Posted January 16, 2013 Get a modded trans in there. Pancake bearing, port match cases, billet impeller and gear by mull, billet basket, fast clutch. I don't know what you have already but my main one is a cut trans. My 4 mil stock cylinder has a hard time shifting. I've gone though 3 stock transmissions and all the same. Get it cut Quote Link to comment Share on other sites More sharing options...
Nightmare Posted January 16, 2013 Report Share Posted January 16, 2013 All new seals for sure, Quote Link to comment Share on other sites More sharing options...
Rustynail Posted January 16, 2013 Report Share Posted January 16, 2013 If your splitting the cases make sure to check shift forks for wear. Billit Water pump is a must have. Quote Link to comment Share on other sites More sharing options...

Forgive my ignorance but what am I looking for on the shift forks? Quote Link to comment Share on other sites More sharing options...
Finch Posted January 16, 2013 Report Share Posted January 16, 2013 discoloring sharp edges ect. any tab or washers you bend to lock a nut replace. bigred350x has a good bottom end walk threw too. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 18, 2013 Report Share Posted January 18, 2013 Just go to the FAST web page and go through the entire OEM parts section and get every nut, washer, beating, seal, and special bolt or tab known to man. Do every single shift mod you can find on here and cut your trans FOR SURE! Weld your crank. Beef up the clutch and get your self a lock up. Some say you don't really need it but you will be right on the edge, and it's nice to be able to run lighter springs and still have a clutch that doesn't slip. Do the Billit water pump, I'm still skeptical of the Billit gear thing though. But I guess if you got the dough. Do the idler bushing and new snap ring. Also a few months ago I started an engine assembly tips and tricks thread.

BigRed350x Posted January 19, 2013 Report Share Posted January 19, 2013 Check the techical info section, i have a bottom end assembly walkthrough in there that might help you decide what to replace. Any time i do a bottom end i try to replace the folowing: Flywheel key Water pump o-ring PTO gear lock washer Clutch nut lock washer Both crank seals Output shaft seal Idler gear shim, washer, and snap-ring Shift segment adjustment cam bolt & lock washer Clutch arm spring, seal and washer Bead-blast your cases Get a shift pro kit Do the shift star mod Dont forget to grease your clutch rod and ball Side-cut your gears if you have enough time/money Do the shift shaft mod Put 2nd bearing on the end of the shift drum Port match your top case Quote Link to comment Share on other sites More sharing options...
