Wasted crank bearings

[1976RD400C]

are there enough rod kits, bearings and seals available out there for rebuilding personal cranks that aren't trashed beyond repair?

You can get the 4 main bearings from Yambits for about $100 a set plus shipping and tarriff. OEM is double that. The rod kits are about $100 each. No problem getting that stuff.

thanks, good to know Given that, it kinda makes the idea of commissioning someone like Vito's to build a minimum order of 500 with huge upfront cost less appealing.

I wonder if these guys would ever make a run of RD400 if contacted? They do a LOT of 250/350 new cranks. I even bought 2 of them and they look really well made- but haven't installed yet to rate them.

its cheaper to rebuild a 350 crank as well, if you can do it (i can) but honestly,  not worth my time to save the 150 bucks, and no dealing w those stupid pressed in weights

Just thinking out loud but has anyone looked at a +10mm Banshee crank as a place to start.  That's a 64mm stroke but I assume that they use the smaller diameter banshee/350 sized crank wheels and 115mm rods, so it would need 350 cases and a 1mm lift plate and a little crankcase shaving to squeeze the crank in, but it has to be an option.

You could always weld up the cases to take a 68mm CPI top end but that's getting into silly money. I also don't know if there's enough metal in the cases to be trenched for that long pf a stroke.

Just thinking out loud again.  No.  No.  It's not time for my meds.  I have been a good boy. Honestly......

to that point.. vitos could do tthe same w the 350 crank, just use offset rod pins you'd gsin some crankcase volume, hut it would be negligible
