ArdWrknTrk Posted February 24 Share Posted February 24 those load springs can be dangerous. getting the two ballanced can be tricky also. The REALLY dangerous ones are the torsion springs that wind up over the door. I've had an extension spring break in the middle of the night, at the house I had in the '80's (it didn't have a safety cable strung through the middle) That thing went right through a stucco wall and poked out in the basement! 😳 Link to comment Share on other sites More sharing options...

The guy said that if it jams or otherwise go sideways, don't touch it. He says everything is spring-loaded and may not behave in a way you expect. The way he said it, I'm inclined to believe him.

I realized after they were up and mounted, and I closed in the front wall that the upper mounts for the doors to the tracks weren't accessible any more. I may get up there and take the sheet metal covers off and tack the nuts to the door roll end plates. Winding the torsion springs wasn't real fun, I made a bar to rotate the wheel on the end opposite the drive sprocket so I could tension them in increments until they ran smoothly (not quietly though).

With the door raised at all, you can't really get at the header over the door. Commercial units usually have a chain fall at one end, in case power is lost. Now we have to deal with every unit having battery backup to save us, in case of a power outage! . Link to comment Share on other sites More sharing options...

I took the truck for a drive this weekend. Unfortunately the hesitation is still there (I had high hopes), but the good news besides that is when I got done driving it, I ran a KOEO and KOER and both came back completely clean. I think my wiring changes are done for now, but does anyone have a picture how the harness is kept in place? Right now the harness is against the firewall as that's how it was before - it almost brushes up against the kickdown rod for the AOD. I'm wondering if the harness is supposed to go between the block and the kickdown rod instead? I don't think it's really impeding anything as it shifts fine. I just need to either disconnect everything (yuck) and pass the harness through there, or figure out how to affix it to the firewall. Thoughts welcome, or if you have any pictures of how the harness is routed/attached at the rear of the engine, that would be great! Link to comment Share on other sites More sharing options...

Bummer on the hesitation, but goodness that everything else seems to be working. I don't have any pics, unfortunately. And I just looked through the 85 EVTM and didn't find any illustrations that help either. Link to comment Share on other sites More sharing options...

And I just looked through the 85 EVTM and didn't find any illustrations that help either. I know I have brought this up before, but as a sanity check: Is there any validity in thinking this is somehow tied to my transmission or torque converter? The hesitation is really only when the truck is in drive. Link to comment Share on other sites More sharing options...

The hesitation is really only when the truck is in drive. Remind us of how hesitation feels and when it happens? Is it in all of the gears on the AOD? If it does it in OD then it isn't the torque converter. And does it do it at all temps? Link to comment Share on other sites More sharing options...
ckuske Posted February 28 Author Share Posted February 28 Remind us of how hesitation feels and when it happens? Is it in all of the gears on the AOD? If it does it in OD then it isn't the torque converter. And does it do it at all temps? It only happens from a stop (1st gear). In general, the engine is responsive throughout the throttle band. You can gun the engine while driving normally and the engine is responsive. It does do it at all temps, but when the truck is cold (just started) the idle RPM is higher so when you press on the gas, the hesitation is much less, or gone. Once the engine is warmed up and the idle has dropped, the hesitation is there at every acceleration from a stop. If you give the gas pedal a little more throttle, you can feel the engine almost "drive over" the stumble and thing will go correctly. If you give the truck just a little bit of gas (as you normally would from a stop), you will feel and hear the engine begin to die. If you give more gas, it will recover (most of the time) but sometimes you may be too late and it will stall anyway. My theory (which is completely unfounded, since I have no practical knowledge in this area) is that if something in the torque converter is compromised and it is taking more work to get going from the engine, then that extra load might be causing the engine to stall. Giving the engine more gas overcomes the issue of the extra load, and is able to stay running. I just don't know enough about torque converters or transmissions in general to answer whether this is a valid theory or not... Link to comment Share on other sites More sharing options...
