Topic: BRM 962C gearing

I need to replace the crown gear on my BRM 962C. I currently have a 9 tooth pinion but could change it if needed. Per the rules you can run 9 or 10 tooth pinions and 34 or 36 tooth crowns. Any suggestions about the best gearing for Al's track?

Re: BRM 962C gearing

I am running 9/34. Seems to work fine.

Re: BRM 962C gearing

I would recommend a Parma gear if you're replacing the crown on an inline chassis.  They are much more robust and tolerant of shock loading.  There is also a wider range of number of teeth available.

All Parma gears are permissable under NASTE rules but you'd need to be stock if you race at Tacoma.
