I’m currently in the process of upgrading a West Side models Hon3 T-12 locomotive, and I’m having a bit of a problem with the driver quartering. Namely, the isolated wheels on the lead and trailing driving axles are very loose, to the point where they will actually fall off the axle if not held in place. These are metal hubs on metal axles, with a plastic isolator beteen the hub and rim. The axles themsevles are 2mm diameter where the wheels go on, then ‘step up’ to 2.4mm to go through the bearings.
I’m currently using CA to hold the wheels in place, but I’m wondering if this is the best option? Soldering is out, as the space taken up by the solder would mean that the axles wouldn’t be able to turn properly in the bearings. I would welcome any suggestions.
I’ve heard CA is not very resistant to shear stress and thus would not be an effective adhesive for securing wheels to an axle. Perhaps a Loctite product would be suitable, which is what A Line sells as a flywheel cement.
Thanks for your replies. I’ve managed to locate a loctite dealer out my way. I’m guessing that ‘Loctite Blue’ is the product I should ask for, and that the drying time will give me time to gauge & quarter the wheels?
Yes, Loctite is the product to use. If you feel that the clearances are just too loose, try knurling the axle prior to assy w/ Loctite. Rolling a smallmill file or marking w/ a serrated jaw needle nose will give more “tooth” for the bond. Although I like thr Loctite Red, this is more permanant and sets quicker, Blue may be the better choice for ample time in quartering.
Loctite can be found at any automotive parts/ supply.
