I don't know if you should write so much a "tech" article - could be quite time consuming to document everything - but more of a list of all the things you had to do. Rather than explaining how every part comes off, writing something more along the lines of a checklist of all the pieces that have to be removed and then installed could be quite handy. So when you go to do it again, you can just go through the list as you remove everything and you don't end up scratching your head wondering if you've forgotten to disconnect anything.

Date: Wed, 25 Oct 2000 18:54:30 -0700 Used one or two years on the Bird or Torino, 68 or there abouts. Makes it a legal carb for Fords In my book :-) The main advantage the Rochester has over the competition is they deemed it a good thing to make the primaries very, very small. Ford, Holley and Carter spread bores have much larger primaries so don't carry off the "Efficiency" thing as well. I've seen a couple of Ford's with pretty small ones but still larger than the Rochester. I used the smallest one of the batch I had lying around but the Ford versions are not tunable so I can't get the most out of it. Rochesters are tunable from idle all the way up to WOT but you do have to know what you are doing. A poorly tuned Rochester is a lot more headache than a Holley or Ford because they are somewhat more complex.

Phila PA area. ================================== Ok. There aren't that many u-pulls around here so where is shortie and dave's u -pull???? ------------------------------ From: "Gary" <gpeters3 Subject: Re: cracked frame around steering box Date: Wed, 25 Oct 2000 19:24:23 -0700 Well, moving the box sideways will not affect the "Alignment" but it will affect the position of the steering wheel and centering of the steering box. With a lift you just about need to get an adjustable drag link to re-center the steering box so the wheel can remain in the factory positon for better handling when going straight at speed. Steel is just steel and a frame is just a bunch of steel welded together so "V" out the crack and weld it back up, simple as that. Make sure you weld "Hot" enough to get good penetration so you get a full thickness repair. If you don't go good vertical welds then try to find a friend who does or use a wire welder, they're much easier to use on a vertical surface. If you are hot dogging it then you do need to reinforce this area usually but don't just put a small piece over the box location, make it larger to spread the loads over a larger portion of the frame to reduce fatigue. On Fords, these cracks are usually due to loosening of the box mounting bolts which causes lots of movement and eventually fatigue. Once you get it fixed up, keep them tight :-) All welds in this case should be longitudinal, never across the frame or if welding across the frame pick a place that has more steel in it for support. Welds cause fault or stress lines along their edges so Transverse welds may crack and cause the frame to fail unless you can use a torch and anneal or at least stress relieve the weld area.

I didn't "V" out the frame. Had I known this would have been advantageous prior to just welding a plate on top of the frame, I might have done so. After bolting everything back together, I noticed one more small crack on the frame going horizontal (inch/inch and a half) right at the bend (in front of the box) of the frame. Had I seen this (before it was dark and I was showing my dad) I would have grinded it down and just lined up a weld right on top of it. I dropped it back off at the inspection station, and if they say I need to fix it, I'll be at it tomorrow afternoon. If not, some other day will do. Either way I'm going to fix it, but I just want those stickers!! Side note: Every time I weld under my truck, I seem to get a chemical burn? This is only the second time, and I had a fan blowing the gases away from my face, but... anyone know what this if from exactly?

Date: Wed, 25 Oct 2000 19:37:01 -0700 Ok, I may have gone off on a tangent here. If the wheels have the same torque applied to them then the axles have that torque applied also. The picture I had in my head is in a truck application where you may have very high static loading a lower (higher numerical) gear ratio in the diff will require stronger axles. Since the F-250's all use the larger axles the most common ratio is 4.10 which also happens to be appropriate for the larger tires they come with. If the Over all ratio is the same then the axles will have the same loading regardless, sorry. I believe I got off track on this one :-) What I was originally arguing is that they use lower axle ratios to reduce the effort on the OD gears which is true given the same input torque. With a stronger tranny you can run taller gears and larger engines etc...the axle thing was a brain fart, sorry :-) Happily Totally Retired, Michigan Pot Hole Jumping, 78 Bronco Loving, Gary :-) > My contention is this is only applicable to acceleration and not steady state ------------------------------ From: "Gary" <gpeters3 Subject: Re: leak from rear end Date: Wed, 25 Oct 2000 19:46:16 -0700 The torque on the pinion nut is around 275# and this rear end uses a crush sleeve so when you get the seal replaced you need to get the nut back on to the same torque as before to ensure the same preload on the pinion bearings. If I ever take mine off again I will use locktite on it to keep the nut tight. This seems to be a problem with the 9". As to whether the seal is accessable from the outside, I can't remember but I believe it is :-( I made up a special puller for applications like this where there is a shaft in the way. Some of them can be popped out with a screw driver if you are carefull by levering it against the under side of the seal on one side and the outside on the opposit side (you need a long one for this to get enough leverage).

With abuse (doesn't always take a lot) larger tires or improperly shimmed can get destroyed quite easily. jack up the offending side and check for movement. If the bearing is completely gone the top of the tire will have a slight angle in at the top, the knuckle wipers will have excessive ware on them or be miss aligned and leaking. ¢.02 -- Don Grossman duckdon ------------------------------ From: "Gary" <gpeters3 Subject: Re: cracked frame around steering box Date: Wed, 25 Oct 2000 20:11:10 -0700 It's called "reflection" the Ultraviolet rays bounce off light colored surfaces behind you and reflect off the inside of the mask. You can get some serious burns that way. It's a really sneaky thing too so you have to always be aware of this before setting up a job. For wire welding you should be using a #12 green lens. For some stick welding you can get away with #10 but I find this a tad too light for my eyes. You need to keep them clean so you can see what you are doing. Use plastic on the outside and glass on the inside. The plastic lenses are throw aways but will take a lot more abuse from hot slag than glass will, vastly more. If you always wash them with water they will last a long time.

Is this correct? I don't recall if the Dana 60 used a steering arm block that tall and that has got to be a dropped drag-link (after market) and way to much arch in those springs to be stock. Just start with all the basics. Look at the entire front end for parts with obvious ware( starting with the least expensive first) and work you way from there. Might want to jack up the front end and have a look at the knuckles. give them the old shake the tire test If you have movement between the knuckle and the yolk that could also be adding to the problem. Start with the steering shaft to the steering box then move on to the drag-link, tie rod ends, make sure the front end is properly aligned. By now you should be able to tell if the steering box is the real source of the problem.

Engineers know that when you step on the gas you want maximum power. There is nothing you can do about the amount of air (oxygen) in the mixture (thats defined by the cam and ports and valves etc.) so you need to utilize every last molecule of Oxygen, not fuel under WOT conditions for maximum "Power" efficiency whereas, at cruise you are trying to get maximum economy (Fuel efficiency) so the fuel system is designed to supply more fuel than it really needs for a perfect 14.7:1 ratio under WOT conditions to guarantee this and just barely keep it running at cruise, that is vey lean where power is not critical. Obviously the average touring engine is a compromise between these two extremes and tries to accomplish both but we all know that if this were possible "Racing" engines would have the same system on them as touring engines. The vac is on there for "Driveability" and cruise economy due to the large variation of rpm used in touring. Most ported vac's would leave you at zero vacuum advance at high rpm, no throttle (decelleration) where you would have full advance with Manifold vacuum. Most of these carbs also have dashpots to prevent sudden closing of the throttle so this is not exactly cut and dried so to speak :-) Happily Totally Retired, Michigan Pot Hole Jumping, 78 Bronco Loving, Gary :-) > This makes sense sort of ... though I'm not sure why you have a rich condition, > I mean it shouldn't be excessive anyway, though probably richer than a cruise > condition otherwise the motor wouldn't accelerate... > > Frankly we've all agreed that WOT puts the vaccuum portion of the advance out > of the loop, and its back in as soon as you let off, but is it advancing or > retarding when you let off ? Also what about idle condition ? on ported it .... To access the rest of this feature you must be a logged in Registered User Of Ford Truck Enthusiasts
