I am looking for someone who has delt with the MAN planetary hubs. I am trying to change the road speed and my calculations show that removing the reduction in the hubs will do it.
Yes i just landed a job at san francisco's MUNI bus services.The new electric buses that i work on are driven by plantary(sun) gear system.These buses are the newest in the fleet and are being built in the Chek Republic which would explan the technology.i'll look arround monday to see if anyone more knowledgable than myshe the answer.
Have you found out any info on changing the gearing yet...I'd like to do the same to my bus conversion. Have also 4-new-chunk assemblies with ring and pinion setups.
Steve,
Could you check those assemblies for ratios? Mine is a 3.45:1 on the differential. My Hubs are 27/18 teeth count giving a 1.5:1 reduction. The overall reduction is 5.175:1. I have not been able to figure out if MAN changes the gear ratio at the differential, the hub or both.
