Tii Injection pump throttle plate bent...normal?

[repoman]

So I am in the midst of measuring and lubing my tii throttle linkage and noticed that the throttle plate on the injection pump is bent where the connecting rod attaches.  It's hard to imagine that the connecting rods or shaft could bend this.  Just wondering if this is normal.  I have seen other pumps (see last pic) that this is not bent.  Or maybe it depends on the model/year/style of injection pump.  My car is an 06/1974 production, however, the IP is stamped 73.  Just wondering if I need to bend this back into place.  TIA

Should be straight like the others. Jamming your foot on the gas pedal could do that.

Only if the stop is adjusted wrong?

changed the s to an f to make a bit more sense...

The stop bolt on the pump contacts the arm lower than the ball pivot.

Hmmm...when the linkages are set, the gas pedal stop should NOT allow any more pull on the lever.  Right?  I think the linkages were not set correctly for that pump.

irdave, look at the FI manual regarding the linkage setup process.  Pedal at full throttle, lever just touching its stop, with the 5mm hole in the KF pump exposed in the 4th notch of the lever.

 

Do you have a stop at your gas pedal? 

Or sometimes the tii gas pedal is replaced with a non-tii gas pedal.  They are different.

How do they differ?  I didn't know that!  Mine is probably wrong...

The stop nub on the top of the pedal is different.  I'll bet someone here has pictures.

little scraped up from the vise, but a lot straighter now...

 

Here's a pic of my tii pedal.   I think it is a bit thinner and longer than the other

I agree you probably need to reset the linlage lengths. You need some special tools to lock the pump. Nothing your can’t improvise though. The hook tool locks the pump. The pin tool acts a a stop in the throttle body. I’m sure that FI link above goes over it. Good luck.

My '74 tii with production date 10/1973 per realoem looks just like yours, bent. I thought is was damage also for a while. But as I looked closer I could not see any of the metal buckled around or underneath the nub. Also the bend is toward the front of the car. So something would have to be pushing from the rear toward the front to bend it that direction. The only piece connected to the nub is the last of three linkages that connect the accelerator pedal, and throttle. Pushing down on the pedal pulls the nub rearward to open the Kfish for more fuel. Releasing the pedal pushes the nub forward. So in an extreme case the pedal would have to be lifted even further back toward the rear of the car to put forward pressure on the nub. And the original ball joints were plastic. I think it would be very unlikely that someone would have forced the throttle linkage in a direction that closes off fuel to the engine, and with a force that would bend that piece of steel. Therefore I think the "bent" looking nub is original.

I also think I saw some other pictures on the FAQ with similar bent looking nub.

 

Does anyone else have pictures of their kfish?

Here's a few. There is a bend and it is most evident in photo #2. I have another pump at Ingram Enterprises being rebuilt. I am curious to see what that one looks like.

agree, the force of the gas pedal would bend the lever the other way, if that was at all possible...pretty tough to bend it.  I would think the rod would bend before this plate.

I looked at about 5 different pumps and most were bent like mine, while the others were straight.  It appeared that the earlier style were straight, however, not sure if that is correct.  I believe I jumped the gun on straightening mine as it does not fit right now.  The connecting rods are pretty spot on with the length...looks like I need to try and bend it back...hopefully I don't snap it!!

I have two pumps, one from a Feb 1974 tii and the other from a July 1974 tii. Both have the bend in the arm.
