    Need help with part number/name 1987 V3500 7.4L N TBI

    Greg The parts manuals are an invaluable source for info on these trucks. I have the factory service manuals for 86 and 87 if you have need of info that they may have. They helped me putting a locker in my 86 Dana 70HD in the 90's. Back then we didn't have the internet resources available now...

    Engine oil capacity

    Bart Some history from someone who remembers many of these changes: -Oil pans up to 73 had a thin seal between the timing chain cover and oil pan. Starting in 74 they went to a thicker seal and the change was made to the oil pan. -Small blocks originally had driver side dipsticks. Starting in...

    1987 V3500 Engine update

    Jeff The LT9 350 and 454W were carbureted thru at least 1988. What all they were available in is debatable. If you have the SPID label showing an LT9 it was carb'd in 87. Some of the pics below support this. If you have any further parts manual illustration/part number questions please reach...

    Need help with part number/name 1987 V3500 7.4L N TBI

    A couple more. One of the last post appears to be a dupe, apologies.

    Need help with part number/name 1987 V3500 7.4L N TBI

    Greg Sounds like you may have it figured out. Below are some pages from a parts manual that show it as either a sensor if it has gauges or a switch for the cooling fan if no gauges. These may be of help in the future.

    Greg The pics you attached show the sensor on the cylinder head between exhaust ports. Is that the one you're referring to? Butch

    Rochester Quadrajet issue

    Dan Set curb idle with engine fully warmed up, it should not need adjusted after that, leave it alone. The fast idle settings are for a cold engine when the choke is in operation. If they are amiss the problem is likely in the choke linkage of choke pull-off.

    1983 chevy k30 dually width

    Matt Nice truck! The pic below may help you decipher your VIN. Bucket is on point with the wheelbase measurement, it will definitely determine reg truck or chassis-cab no matter what may have been changed over the years. Unfortunately, over the years many of these awesome trucks have been...

    Quadrajet Secondary issue?

    Tyler By your description, and assuming that when you said "until I floor it to kick it down a gear" it accelerates normal/good, tells me the secondaries are not the problem. The secondaries are doing what they should. Part throttle tip-in is not getting fuel flow. Could be many reasons but I...

    Can anyone tell me what this is??

    Based on this blah blah blah of from the internet cut-and-paste pseudo-info, ad nauseum, I'm guessing you were a bicycle mechanic. Maybe you should spend some time wrenching on something with four wheels.

    Can anyone tell me what this is??

    Surfer Before you post a comment, you should read the question and your post, if you can understand the words. You said surge brakes (and yes, I know what they are) were only legal in CA in boat trailers. Last time I rented a dual axle U-Haul trailer (in CA) it had surge brakes, ya I still...

    Can anyone tell me what this is??

    Did CA outlaw the surge brakes on U-Haul trailers?

    Can anyone tell me what this is??

    Surfer First off please refer to my post last week and reread the entire thread. An example may illustrate, have you ever been in a group setting and someone asks "why do politicians suck so bad?" and there is that guy who pipes in with "well actually, just like an internal combustion engine...

    What is this vehicle?

    Not sure which year of Found On Russian Dump Exploder (or its big brother the Excavation) it is, but if she would have smacked it a little harder it would have fallen apart for sure.

    Can anyone tell me what this is??

    I would suggest staying a retired Ford mechanic, or studying Pascal and researching the volume of fluid required to actuate the trailer brake controller and its effect on the system. A doctorate in Hydrology may help you. I believe PrairieDrifter called it good.

    Missing sway bar bolts. Anyone know what size they are?

    No Prob Hope it helps.

    Missing sway bar bolts. Anyone know what size they are?

    Grumba Just did some digging (see below, part no 29), all the 4WD use the same bolt. Its 3/4-10 x 3 1/4". The OEM part number is 328130. Sourcing aftermarket you should ensure the bolt is grade 8 case hardened. That length may be hard to find but a 3 1/2" could easily be shortened. Good Luck Butch

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    Virgil Wasn't baggin on the 208s. Had one in an 84 K10 and never had a lick of problem, they're a good box. Just answering the "what is a 1 ton drivetrain" question, nothing more. Butch

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    My point was that the all gear NP205s are generally considered to be stronger/better that the chain driven NP208s. Nothing more. Butch

    New to the forum, but not to Squarebodies...

    Tim Just came across this post. Attached are the diagram for your A/C system and the parts list from a 1985 parts manual. C60 is your standard A/C, C69 is overhead A/C. Sounds like you are looking for parts #8 and #9. Those tubes were not listed in the 1985 parts manual. This tells me they...

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    Jay Just came across this post and it appears no one gave you an answer. Generally, when the "1 ton drivetrain" is mentioned, it includes T400 (although some 1/2 and 3/4 tons also had these), NP205 transfer case (this is the gear drive case... no chain), Dana 60 front axle, Dana 70HD or 14 bolt...
