1980 Terra 6.9L IH Diesel RePower Thread

[Eldon McFarling]

you got the wrong tach. the 2" one is not the one you want. that one uses magnets glued to the damper which are always coming off. the one you want is programmable. don't have the number handy, I can look it up later.

I don't know if you can get the older style rockers anymore, at least you can't get em from Ford or Navistar. Just ask for rockers for a '90 7.3L. they come assembled so you need 8 for a complete set.

humm.... so it'll go in the "stock" tach pickup location??

thanks,

and again, i have another question for ya!

ok....I KNOW I DON'T HAVE TO! BUT i'm running a pyro on my n/a diesel, i'm going to monitor this motor like a paitent on life support! now here's the question of concern, it's DUAL exhaust, no Y-pipe i'm planning on running 2 Autometer pyro's, is there and pyro setup with a "split screen" or a 2:1 gauge? i have both gauges still in the box, i can take them back, no big deal. and what's the "danger zone" temp. i will have to watch out for with my N/A 6.9L diesel??

also i was looking for glowplugs, i was told autolites are junk, what's the best ones to go with, i read that the motorcraft zd9 plugs are the best bet they're a "sever duty" plug. i hear swelling is a problem then they fall off in the heads! i'm getting kinda scared with this whole glow plug setup...should i just use the stock button with the ford solenoid and the ZD9 plugs? i don't need the keyto light the plugs i'll be happy with it just shutting it off! again getting scared with wiring and i'm just looking around!!!!!!!

thanks again!

If there is an International dealer near you buy your glow plugs there.

Look into aircraft parts. I've seen an eight cylinder pyro before, you can probably find a two cylinder version.

IIRC all you need to do is count the teeth on the drive gear, then program the tach head for that number of impulses at 1/2 engine speed. I think you can use the stock magnetic pickup.

Since we are on instruments here I guess I should continue with a few thoughts. Take a look at BinderMarks cockpit:

http://api.ning.com/files/LTOk8BRZJP...500&height=375

in case you were wondering the top row is all stock with the 2" tach attached to the column. On the AC duct is a second digital tach, on the lower panel is a voltmeter, vacuum gauge, oil pressure, coolant temp, pyrometer- boost combo, air pressure for the air shocks. I can go along with some redundancy since the stock electric gauges are often inaccurate, but how useful is this stuff if you can't see it, or it causes you to run into a stalled J**p and mess up your nice grille. My point is its always been tough to add gauges in a Scout in a location where you can easily read them and now you want not 1 but 2 pyro's?

There is really alot of confusion on what you really need. if you have a 6.9 with the stock pump setting with a D20 or a dinky driveshaft, or whatever the weakest link is in the drivetrain its gonna come down to this: If you pull a load or overfuel the engine to the point you need to monitor the exhaust that close you are surely gonna damage something in the drivetrain. Most likely you won't pull it that hard, or fuel it that much so monitoring the exhaust temp that close should not be a necessity. Having a pyro is a good idea, just for the coolness factor if nothing else.

Perhaps more thought should be put in your air cleaner and exhaust system to make the engine efficient without any restrictions that would cause problems with high EGT's. I think you will be able to better flow from a single exhaust than from a dual setup. By using a Y pipe the flow of exhaust has a scavenging effect. I think if it was me I would go that way.

Welp, I have to run. I'll have to add more later

If using the stock setup with the timer and such, use the Motorcraft/Beru glowplugs.

If converting a 6.9(blade connectors vs barrel on 7.3) to a manual button, <edit> DO NOT</edit> consider the AC Delco 60G plugs. The 60Gs will not work <edit - insert period here, disregard the following>with the stock glowplug timer but will work well with a manual button. They will not swell, they will not prematurely burn out even if you leave them on for a few minutes. They are listed for GM 6.2/6.5. Wiring a manual system is very simple.

Are you saying that the AC 60G glow plug that is for the GM 6.2/6.5TD fits the Ford 6.9/7.3?

yep, pretty sure they're the same. i think i'll be going the easy push button route, i saw 60% of the ferd fourms converted to the trucky button because the timer pooped out.

Eldon,
i may not get too silly with it now, it it may slowly turn into a pulling rig, replacing parts as they twist their way out from underneath it, the screw will start getting craked up and the smoke will start pouring. i want to be prepared. i realllllyyyyy do not need 100 million gauges, i saw that one at nats... never ever have a need for that many. the only thing i want to watch is EGT, temp., and oil Pressure. for the exhaust it's getting dual stacks, was thinking crossover pipe, but was told it isn't necessary. and the air cleaner is probably going to consist of a 5" tube with eith a big cone filter or some form of airbox.

Yes <edit> I was but now I'm not</edit>, with the caveat for connector type.
