I have for sale nylon drawbars for American Flyer S-gauge diesel engines. They are sized to close couple the engines. Pics #4 and #5 show an ALCO PA engine and an ALCO PB engine (slug type) on both straight rail and curved rail to illustrate how closely coupled. Use these drawbars to replace those horrible AF fiber drawbars, as shown by a broken one in pic #3. These drawbars are made of wear-resistant black nylon 3/32" thick and 1/2" wide. This nylon is tough stuff, almost unbreakable, with a tensile strength of about 12,000psi. By comparison mild steel is about 64,000psi and copper is about 32,000psi. For these drawbars that calculates to about 560 pounds force in the middle and about 210 pounds force at the ends. Plenty enough. BTW, drawbars cannot be made of an electrically conductive material.
When installing one these drawbars it is not necessary to use one of those fancy and expensive little shoulder screws. Instead use a simple #4-40 machine screw about 1/2" long, screw it in to just snug, back off about 1/2 turn, and then apply a dab of Loctite Blue to the backside threads. The Loctite will soak into the threads and secure the screw.
There are six possible types of ALCO diesel drawbar connections, depending on the trailing engine orientation and the truck side frames, as listed below ...
Leading PA to trailing PA running forward
1. knuckle-type side frame to knuckle-type side frame, 42mm hole-to-hole
2. link-type side frame to link-type side frame, 48mm hole-to-hole
3. knuckle-type side frame to link-type side frame, 45mm hole-to-hole
Leading PA to trailing PB or PA running reverse
4. knuckle-type side frame to knuckle-type side frame, 29mm hole-to-hole
5. link-type side frame to link-type side frame, 34mm hole-to-hole
6. knuckle-type side frame to link-type side frame, 32mm hole-to-hole
Pics #1 and #2 show a Type 1 drawbar.
When ordering please message me and specify what type you want.
As a side note, it is not possible to have a trailing PA running reverse with a link coupler.
