1977 Dodge B200 Doghouse Bushing - August 25th 2019 12:20 am

Hey guys, I've been lurking on and off for about a year now. I have been fixing up a 77 B200 Street Van (no cool paint, has some junk RV windows, but the carpet is original and it's a YH3 code van.) My throttle linkage isn't fully engaging, and I tracked the issue down to the bushing where the rod enters the engine compartment, right behind the doghouse. I'm having a hell of a time finding the part and was wondering if anyone had any spares/info on where to find one/tips. I can only get the damn thing to open the butterflies about 60% and it's driving me bonkers, as this van also gets dailied.

Welcome from Florida.

I had the same issue with my 85 Dodge. I had to fabricate myself a new linkage.

This part of the linkage is what I'm talking about, the rotating shaft that goes through the firewall. IS this part of what you fabbed? MY buddy's 79 Trans-Van has a completely different setup from this. [Linked Image]

77 and 79 have different throttle linkage setups. Mid Dodge vs. Late dodge.

The northwest region of the US where you are located seems to still have a lot of the older vans on the roads. I would suggest checking out some salvage yards to see if you can find a replacement. Have you tried taking the connection apart and cleaning and lubricating.

6030980 is the part number for the spacer or bushing on the pedal. I would also check further back near the carburetor where the spring return is and a couple ball joints on the linkage to make sure the spring is not worn out or the linkage is hanging up.

If the butterflies are only opening part way, first off I'd look at the linkage clamp on the accelerator pedal shaft, (shown in your picture) in case it's slipped into the wrong position when your accelerator pedall is floored, then I'd scrutinize the threaded rod end in the linkage. You can adjust the length of the throttle rod quite a bit by turning that rod end.

I've seen the accelerator pedal bushing get really sloppy, but still work pretty well; the main issues I've seen with worn ones are a lack of repeatably returning to low idle. Something bigger is going on if the butterflies are only opening 60%. Perhaps the linkage is even bent.

The butterflies should range from fully closed to wide open when the rod end and pedal shaft clamp are adjusted properly. They can do it even with a fair amount of slop in the shaft bushing. A heavier spring can help with settling to idle in the case of wear.

If the linkage has been screwed up/with, (you might get lucky and see what fresh threads on the rod have been exposed since it was first set up at the factory... ) you may benefit from going over the entire suite of carb adjustments and the super important throttle kick down adjustment (on the transmission). It's guaranteed to not be correct if you're not able to open the carb properly. Your van may behave very differently in short order!
