Sharknose A-A Lash-Up

krybkaOGR Forum Member DIGITAL SUBSCRIBER

Hi,

I’m getting back to running some trains after a couple years of life distractions. I have a Lionel Century II Sharknose A-A set. I am using a CAB-1 with a PowerHouse and a TPC 3000. In theory the Sharknose A-A came pre-programmed for a lash-up. However, the speed difference between the two A units is significant. I have set the momentum to L on both units individually and as a lash-up. I did the same with stall and maximum speed, (individually and as a lash-up). Still no luck. They run great independently but the speed differential remains. Any suggestions?

Thanks.

Ken

Are they both greased and oiled? As TMCC locos go we've found ones like these, built from the same parts at the same time run best together. Would try a reset and go from there. Not sure changing the momentum would enhance their speed compatibility.

They are very nice engines.

You said you set the stall as a lashup. That would be my first step. Maybe one unit needs more break in time? Those are pullmor powered aren't they? Maybe clean the old grease off the axles, open them up and oil and lube the units where recommended in the manual, including the pullmor, and them run them hard for a bit. Good luck. Those should be fun to run.

Thanks for the quick responses. I suspect that the slower unit may indeed require cleaning and new lubrication. The manual only shows lubrication points accessible from the bottom so I guess the next step is to remove the body (without breaking the antennas!).
