K-LINE GG1 K2780-48921C Front Trucks Parts and Repair help.

From what I can remember about the front trucks is that the spring and washer are pretty much the same as Lionel's.  I had a lot of problems with the fast action wheels always derailing so I replaced them with the flatter post war types, derailing stopped.

Wow. Interesting. I'm glad I'm not the only who experienced this issue. I don't feel like going through the trouble of changing the wheels, but I would like to know which Lionel springs and washers to buy. Do you remember what the Lionel part number are? Thanks Marty.

According to Lionel web site, you will need 4 washer's #6308302P15, .50 each and 2 conical springs 6308064049, at .80 each.  You might try the Train Tender, he will have them for less as a rule...

I have photos in there of the placement of the washers and springs

Wow. Thanks Marty and Roger for the information. You guys rock!. 

What curve are you running it on?  These are not O27 locomotives.  Mine climbs out on anything less than O36.

I'm running it on Post War O Gauge Tubular Track, 31 inch curves.

While I can't speak for the K Line version, my PW 2360 blows through my back to back serpentine 1122E 027 switches.............AFTER I did the modification of the trucks as described in the link I posted above.
