Question for mechanical pump folks.

[DickWells]

I'm gonna need a new throttle cable for the Suberban. The old one ( in there now) is out of a junker and has had a "catch" in it, as you start to add throttle, just off idle. I have the pedal out, the only uncrowded place to put the TPS cable grommet from Compushift, being right above the pedal assembly. So, anyone have a source for a new cable that won't break the bank? A quick G-search found all kinds, but none specific to a 6.2, or 6.5. I'm not averse to doing a couple of mods, but, I'm hoping that TDP folks can point me to a quicker fix.

If it has the 4911 pump and the linkage hasn't been hacked up, you'll want the cable for a 1993 6.5TD. It should be what was used for the conversion.

I used one out of a 89 pickup that had a v6 in it when i did the conversion on my tow truck

As far as I know, the cables are no longer available from conventional sources. You might check salvage yards, but Quadstar Tuning will be coming out with a replacement soon:

Thanks, guys. Dmax, that's exactly what I have in there, now. The 4911 pump came out of a 98-99 big van. I remember that I was surprised, when Burlington Diesel told me that, because I thought that all 6.5 TD's had electronic pumps In them from 93 on.
Not glad, but not surprised that the factory cables are no longer available.
I'll probably order up a cable from one of the suppliers that I saw on my G-search, the other day. Mine measures almost right at 48 in. OA. Having modified a lot of cables in my bike shop, back in the day, I'm not scared of doing a few more mods.������
Thanks, again.

Turns out that the "catch " on my existing cable was due to a swadged on collar, around the inner cable, catching on the plastic shroud at the inner end of the outer cable. Seems that when I inadvertently broke the plastic hinge at the bottom of the old throttle pedal lever, a year ago, it allowed the fork at the top , that pulls the cable, to drop down and thus letting the bottom of that little limiting collar to catch on the hard plastic outer tube /sleeve. I always wondered why it would "catch" when cold, but go back to smooth, once it was warm inside the car. I duplicated the the GM throttle hinge with a piece of half-inch aluminum and now, the "pull" end of the lever is lined up perfectly with the cable and it's glass smooth, again.
Hadn't been for taking the whole thing out to give me room to hole-saw an access for the Compushift TPS sensor wires, I'd have arbitrarily bought a cable, and probably kicked along for months, sputtering about that catch in the throttle.

Had a bunch of question marks in my post, so I hit "edit" and took them out. Now, I expected to just hit "post", but can't find it, so, I hit " post quick reply " and it's opened this new block! Hoping that I don't lose my main message.

Looks like the previous post is fine.
