Tek-Nek conversion chassis

This chassis was developed specifically to convert the Tek-Nek ride-on Thomas to 7.5/7.25"
 gauge.  It has been used for several other purposes.  Because of the psuedo 3-point suspension it tracks extremely well.  Recommended run voltage is 12v for a top speed of 5mph.  Recommended weight limit is 150lbs for the chassis, 65lbs for the plastic ride-on toys.

The single problem with this chassis encountered is the low clearance of the motor, anything sticking up above the railhead between the rails more than 1/2" poses a hazard to this chassis and any rider.

The original purpose of this chassis.  These plastic bodies can still occasionally be found on the used market and at thrift stores.

I was asked to convert this FunRise Tonka fire engine, a lengthened Tek Nek conversion chassis worked very well.  My daughter's getting a bit too big to be my test engineer for ride-on toys.
