AYK Gator/Sidewinder gearbox question

[BloodClod]

Hi guys,

I just picked up and restored an AYK Gator/Sidewinder... really a nice looking car. I'm thinking it's probably the first mid-motor 2WD buggy designed eh?

Anyway, I put a black can in there and took it for a spin and it seems that the plastic diff bevel gears seem to flex under torque - sometimes enough for the diff gears to "slip" and when that happens I can hear a clicking coming from the gearbox. Have tried adding some shims which help but don't totally eliminate this.

It may be a longshot but I'm wondering if anyone here has any ideas on how to fix this issue.

I intend to run this car at our local annual vintage event so any other tips on how to improve the performance of this car would be great!

One last question - know of anyone doing repros of the shell? The one I have is in decent shape but a new one would rock!

Thanks in advance.

The grinding gear problem is common with the AYK Gator.

I have a set of Metal Gears that replace the plastic ones and do not flex.

Who made the metal gears ?

I am just in the process of starting an AYK Gator rebuild. It is actually my first after having been away from the hobby for over 20 years. I got the bug when I saw they re-released my first car, the Rough Rider.

Anyway, using this site for reference, I made a guess that the Gator/Sidewinder body was used again on the Bobcat. (1983 tab on top will take you to the Gator/Sidewinder)

You can order a Bobcat body from our friends in Canada. I don't know if it is an exact match or not which does not bother me but might bug you.

Back in the day I bought the gears from Circus Hobby. I cannot recall if they were AYK brand or aftermarket. The metal gears and a sticker kit is all I have left of my Gator. I really miss that car and wish I could find one.

I bought a Boxer (same as Bobcat and Buffalo) new back in the 80s. The diff is the same than in the Gator (or Sidewinder) and the gears were metal. I always had probles with it. Nilon gears worked better IMO. Having said that AYK also made ball diffs but those are rare...

Here is how the mentioned ball diff looks:
