i remixed this nice 5th wheel to fit the wpl/heng long trucks.
i beefed it up internally,bigger piviot point,included a drop in fit crossmember to take the place of stock cross member and eliminate rear bumper.ill add a new bumper to go along with it later.
ive printed 2 from petg,once cleaned,lite sanding to moving parts,a few drops of oil and she works smooth.
handle/latch spring i trimmed a few coils from a bic lighter flint spring,for the trigger i use a cheap lead pen spring trimmed to about 8 mm.
used a screw from a 9g servo case to keep the latch spring in place.trigger has little dowels to keep it in place.
used left over wpl diff screws for the trunion piviot.
the king pin is reshaped for 3mm king pin/bolt diameter.
drill your own holes to mount 5th wheel to crossmember,or edit n add them in to suit your needs.
locks and latches perfect,i can pit in a pin and hang my wpl from it....its tuff in petg.
i thank the designer for this model that i modded n fine tunned.ill add tweaks as needed.
this one is scaled from original at 55% with handle on drivers side.
still trying to figure out how to add individual files for printing.
(edit) individual files added.
and pics of it installed on a wpl can be found here page 4.
if you build one please comment on thoughts,improvements.
