Been doing some newbie write ups lately for Ford forums and a couple small magazines. Figured it would be worth posting up here too. Doubt it would be beneficial to any old-hats, but someone might find use in it. For whatever reason this always pops up as one of the most intimidating fixes on these trucks...outside of time consuming, it's easy peasy.
This is on a 351M with A/C...but for the most part, most of the steps will be the same on a 360/390 and 429/460.
If you're anything like me, it's good to take some pics of the engine in it's original state and any areas you'll be working, so then you'll have an idea of what it's supposed to look like when you're done.
-I started with draining the radiator...don't forget guys, there's a pet cock to drain, alot less messy than just yanking the lower hose:
-Next, you'll want to remove your fan shroud (if you have one)...as well as the fan (the fan requires a 7/16 wrench), and you'll have something that looks like this (with A/C removed and idler pulley removed):
(For reinstall, place one bolt in the bottom slot of the fan spacer...that way you don't have to try and hold the fan in place)
-Next you'll want to remove the power steering pump (I just removed it from the block and rested it in the bay):
(Keep in mind to get the belt off of the PS pump, you need to loosen the 3nuts on the top side and one nut on the side of the bracket. At which time the pump will slide up and down in that bracket)
-Next comes the Alternator bracket:
(Be sure to take a picture and consult that picture if you're unsure which wire goes where on the alternator...so you don't end up like me and fry your alt. and battery)
At this point in time, I still had my smog pump on, and I decided it was a good time to ditch it. In the picture, you'll notice the wrench to the back side...that's because the bolt went through the block and was secured with a nut:
-Next, you'll want to remove the heater hose and the lower radiator hose from the water pump, and at this point, you should have something that looks like this:
The next step was to remove the crankshaft pulley:
In order to get the bolt out, use an impact.
And now, you're down to the fuel pump (could have been done earlier, but waaaaay easier to get to now), damper, the pointer and the cover:
-Next...be SURE to use the right tool for the job. YOU NEED A HARMONIC BALANCER PULLER. I was stubborn and tried using an old flywheel puller and it put pulling pressure on the wrong areas, and gave me something like this:
So I bought the right puller (only $16 and can be used for several other things as well).
(I did press the balancer back together, but ended up just buying another)
-Next...my cover was stuck on pretty good, so I needed to use a couple screw drivers to get under the gasket and pry it off. Be sure not to bend it, and remember there are also two dowel pins that it sits on. Once you get the cover off, it'll look like this:
How about this chain stretch for ya:
Now comes the toughest part of the WHOLE project, getting the cam gear and the crank sprocket off. For me, the crank sprocket moved easily, so I didn't really worry about it. The books all said to use long screw drivers and wedge them behind, and the sides of the cam gear, and try to pull it off. After toying around for 10-15 minutes that way and bending a couple screw drivers, I decided to just use a pry bar, and I wedged it on the underside...2-3 tugs later, the cam gear and crank sprocket came free:
Upon further inspection, there appeared to be a few teeth sheered off, but the bigger concern was all the 'nylon' coating that was missing:
I had a feeling of where they went:
I was right:
