Along with new oil cooler, etc; I decided to install new dummy plugs and stand pipes. 1st Dummy plug went in fine. The stand pipe white split washer was so loose I called Tousley to inquire. The overlap was roughly 3/16". The other stand pipe has a very minor overlap in the split area. After talking to them about my concern, they thought everything was normal; so I oiled up the stand pipe and slid it into its opening. I held the white washer compressed as long as I could, after releasing the pipe it continued to slid a little ways and then hung up well before the threaded area. I applied light pressure and when there was resistance I pulled the stand pipe back out. Part of the white washer was out of its groove. I then installed the 2nd stand pipe with the tighter white washers, they went in with no problems. Called Tousley on the 1st pipe with the loose washers. There diesel techs were gone for the day so asked me to call back tomorrow. I feel like there is a overly large white split washer on the 1st pipe. I have an extra set of dummy plugs, but not sure of sizing. The inside diameter seems of be possible 3 mm difference in the two shafts. Does anyone have any thoughts.

 

Hey Gary, the white split ring is a back up/support to the o-ring. The o-ring does the sealing and the Teflon split ring keeps it from squirming around as pressure fluctuates. That is to say the Teflon ring doesn't really seal. It's a common set-up on aircraft quick disconnect fittings. You can pull it off an roll it between your fingers with a little bit of pressure to decrease it's diameter as long as it's not kinked or a chunk is missing out of it. If there is too much overlap at the split when it's tight in the groove, it's not the right size. In a pinch you can trim it with a razor blade but it's hard to hold onto and the angle has to be correct.

 

Thanks for your response. Their is a small mark on the washer, but not severe. I think your ideas are a viable fix. I will call Tousley and talk to their diesel techs and post their thoughts on a viable solution. Possibly return the stand pipe and get a replacement from them.

 

My other thoughts. Nothing on this truck is very easy or quick to do unless you have done it many times. This is my first go-around, so don't want to do a less than complete job. Just trying to be very careful, don't want any do-overs.

 

Great Info Rusty

Reps Given!!!!







Totaly understandable BUD And VERY Wise Idea

Even if I have done something Multiple times I take my time and tripple check everything


I have seen on here a Fair amount of folks that change injector/s and Forget to Torq them and endup going back in
