My replacement counterweights arrived today from Bachmann UK, I have succesfully installed them on my K-27
I took me around 30 mins to do all 6.
I recommend that, each side is done seperately, start with Axle 1, when this is done Axles 3 & 4 can be done together, then repeat for the other side of the loco, be careful not to lose the bronze? bearing from the con rods (mine did not even come out of place though)
I would recommend marking the OLD C Weights so that they never get confused for new ones, then stack them in your loco yard, nice bit of 'scenic clutter'
I have posted some pics on www.gscalemad.co.uk
I just completed my counterweight replacement as well.
I used a 9/32 six point socket, a #0 phillips screwdriver, followed the instructions in Bachmann's photo gallery.....25 minutes later: DONE!
I also found that using an eye glasses flat blade screwdriver worked very well popping off the end caps.
Regards,
Soulmann
One thing I didn't recall from the instructions--the need to remove the end caps and retrieve the washer and lock washer from inside the hole. I had finished one side when I found I had missed them. Wht nort furnish the screws and washers as part of the repair/upgrade kit?
