Removal and repair of power pickup assembly on Lionel H16-44

Doug, give us the product number and someone will get you the part number

Sure - I should have done that in the first place.  It is Lionel SKU 6-28813: Milwaukee Road TMCC H16-44.  Thanks.

If it's the top one, the screw that holds the pickup wire on top come out to drop that pickup.  The one on the bottom you take the two straight slot screws out to access.  Personally, looking at the grooves in them, I'd replace both of them.

John -- thanks, but I do not spot a pickup wire at the top.  Do I need to remove the truck?  Is the wire held by the screw in the semi-circular hole (which seems to stop unscrewing well before the assembly has loosened at all)?  The engine is an ebay pickup -- I have the operators' manual, but not an exploded view of a parts diagram.  I believe I have finally found the part on the Lionel support site for this engine (6SP-8590-020), but I am reluctant to start taking things apart before having a better idea of what I am doing.  Thanks again!  Doug

This is one of the puzzle trucks from Lionel, so you have to do a bit more to get it off.  The pickup wire is directly above the truck, normally it's visible through a slot in the chassis.
