Hey guys. I’m having a hell of a time finding a PN for the Dashpot. All I can seem to find is the later generation 22re motors online, but nothing for 87 and older (my truck is 87). Mine ate it this weekend and was a major annoyance. I can’t even find it on the parts drawings. Anyone purchased one, or can find a PN would be really appreciated.

 

Does it look like this one? https://parts.toyota.com/p/Toyota_19...220235271.html

 

no. That’s why the link you send specifies that it does not fit an 87.



here’s mine

 

Missed that. Sorry. Looks like my 86.

 

ask, and ye shall find: 22202-35050

 

I should have guessed you would pull through for me. Looks like it’s discontinued. Womp womp. I peeled the plastic dust shield off mind and that MAY have redneck fixed it, basically it was sticking my throttle at 15-1700 ish until I tapped the gas and got it to settle back. Might have to hit the parts yards.

 

The dashpot just returns the throttle slowly to reduce HC emissions. Glue it shut and don't worry about it.

 

or just adjust the set-bolt so that it doesn't contact the dashpot rod, and then it won't hold your throttle too high.

 

yeah im aware if its purpose. appreciate the tip. im going to look down a few more avenues bvefore resorting a a repair like that. im weird and kind of a stickler for the oem setups in most cases.

 

that was my trail fix this past weekend out at jamboree. worked until i could get back to camp and see what exactly was happening. i tore off the plastic boot and hit it with a drop or two of WD and it may have "fixed it" for now honestly. that east texas hill country red dirt likes to gum up the works.

 

fwiw, one of my '87s doesn't have the valve and hose assembly that attach to the outlet tube on the dashpot. been that way since i bought it in 2013. my other '87 has the complete assembly, and it works (and the dashpot works on the one missing the valve/hose, because i tried the valve/hose from the complete unit).

 

Without this dashpot, will a CA truck fail smog testing?

 

It will fail the visual inspection if missing. You can install it right before a smog test and then remove it later.

 

Mostly I'm wondering if it's non-functional Will the vehicle pass?

 

It might not be the dashpot's fault. I found the sticking high idle was due to a dirty throttle body. Five minutes with Goof-off and a papertowel and all was better.
With the dashpot installed, it keeps the throttle from snapping back hard enough to close the plate against the built up goo. Remove the goo and it might improve. Mine did.

And yes, I'm in the Nanny State so the dashpot must be retained.

 

thanks. this was 3 years ago. i found a great solution for this issue though. pull the 22re and throw it in the trash. install a 3rz.
