Sticky Throttle - Fixed!

For all of you RZR 170 owners....

Background: I had my RZR in for some warranty work, but it sat at the dealer for a month waiting for parts.

When I got it back home, I found the idle was eratic and when I applied the throttle (through the pedal), the idle would skyrocket and would not come back to normal idle.
First thing I did was spray some lube on the pedal, cables and carb mechanisms! Still no luck, played with the gas pedal freeplay settings and carb idle screw...still nothing.
Then I decided to dissassemble the gas pedal housing to see what's going on in there. Upon opening up the housing, it appeared I found the issue. The housing contained mositure and a fair amount of dirt...which was binding the internal operation of the gas pedal. I cleaned it all up, blew out the crap and completely re-greased all internal parts. Inside, there are two roller bearings that the gas pedal sits in...these needed greasing in the worst way. I used dielectric grease where the electrical contacts are within the housing, filled the two bearings with bearing grease and greased the opening where the throttle cable enters the housing.
Once I got it all back together, I crossed my fingers and fired 'er up.....sure enough, the idle was good to go and when the gas pedal was released, the engine would drop back to idle.

Sorry, but I didn't take pics, but it's pretty self explanatory when you take this housing apart.

Anyhow...if anyone is having this issue, this is likely your problem. Just thought I would pass this tidbit of info on.

Bling,

How is that fix holding up?

I had the kids 170 to the shop last year for the sticking throttle and noise in the bottom. $400.00 nothing changed!

Sounds like I followed the same trouble shooting path on this issue. The gas pedal assembly is the last part involved and next on the list. Thanks for the post.

Its not just the 170

Good post cuz my RZR 800 is doing the same thing and ya kinda did what I was gonna do and now I now its worth doing.

Revs to the moon too and thats not good.

Thought it was ice or snow but I did the lube route and no success.

When it warms up I will tear it apart....how in depth of a prolect was it Bili

Adding zerks



Wondering if you could drill an 1/8" hole in that housing and weld a 1/4" fine thread nut to it. Then you can screw in a zerk fitting (most are 1/4" fine thread) and that way you can grease it at anytime without dis-assembly?????

I've done this before on POLARIS sleds. They used to have zerks all over the rear suspension and now there are virtually none???????

BTW, tried uploading pics from my computer, "upload failed" message keeps popping up, what's with that???

Spoke to fast mine is sticking again!

I think I am going to pull it and clean it again and just spray everything with a light lube, I use Remington oil spray for everything. It holds up well and works when the temp drops down here in the North East.

I think the issue now is the cold has the grease too thick.

Once cleaned and lubed I am going to use liquid gasket to close it up tight and see what I get.

What would be the problem connecting to the pedal so the spring returns the are with the pedal? Or putting a spring of some type in there?

Try synthetic grease
