Good Afternoon, I recently purchased the subject line k4, it is dc only. It is a very nice engine. But when running it appears that the side rods rub and catch on the plastic insert of the drive wheels? This causes a bad wobble while running and intermittently or for the engine to stop.

Has any else run into an issue like this and is there a fix that I can accomplish w/o disassembling the engine? Does anyone have a procedure or step by step fix for this?

Thanks

Brett

Good afternoon, We've got a waddling k4 also, do you recommend taking all hubcaps out, or is it possible to identify the main culprit and only remove that one?

Thank you for the responses! 

Good Morning, hoping to find some help. I have a gp35 item 11510 that the leading truck appears that the drive shaft coupling will no longer spin the gearing. I see the fly wheel turning. I was wondering if anyone had suggestions on how to fix that and if part # 6030 would need replaced? Or if other parts would also need replaced?

Thanks

Brett
