Hello everyone. I am relatively new to the Ford community, since I inherited an 86 f150 2wd with a 4.9 in it. I have been collecting parts to fix the front of the engine, as oil is leaking out at a fast rate. The leak is coming from the front cover, more specifically where the power steering bracket bolts to the front cover. I see that one bolt is missing, while the other one was significantly loose.

Are the bolts that attach the power steering bracket to the front cover a bolt with a stud on the end? so that you torque the bolts to the front cover and then use nuts to attach the bracket to the bolts? The PO just used bolts through the bracket and tighten down the cover.

I know the engine in this truck is not the original one, and it may have not been put together correctly when it was replaced.

Length and pitch of the bolts may help as well, since at least one bolt is already missing, Anyone have a source for new bolts, other than at the local store?

And I just wanted to say that, so far, this site has helped me immensely.
Thank you
Adam

 

The bolts that hold the power steering pump on are just normal bolts. I *think* they're a little longer, but can't remember.

As for the size of the bolt, I'm not sure. You could probably pull a loose one out and take it down and have it matched. For the ones for the power steering pump, get them about 1/4" longer (they stick out the back, so if they're too long, it won't matter too much). Or, just grab them from your local junk yard. If you do purchase them, be sure to get hardened grade 8 steel.

Other than that, replacing the timing cover gasket (which is the one you have leaking) can be a bit of a pain, but overall not too bad.

You'll need to get a harmonic balancer puller.

Drain the coolant (if you put it into a clean container, you can reuse it. Or, if you've never done it before, it'd be a good time to put fresh in).

Remove the radiator.

Remove the fan. You may need tools to disassemble the fan clutch. Or, if you're crafty, you may be able to get it with a few good wrenches.

Use the puller to pull the harmonic balancer off. When doing this, remove the large bolt that holds the puller on the end of the cam. Then, remove the large washer and put the bolt back in place. This way, the puller pushes on the head of the bolt instead of the threads on the end of the crank. Been there, done that, had to special order the tap size to fix them.

Replace the timing cover gasket.


When you get your timing cover gasket, get the step up. There's generally two kits. Get the one that comes with the repair sleeve. It's good insurance. It goes on the end of the crank and covers up any wear that the crank's taken over the years.

Cover the gasket with sealant (I think the gasket kit comes with it). Put it in place and put all the bolts in and leave them slightly loose. You want the cover in place, but able to move.

Put the harmonic balancer back on and tighten it down about half way. Basically, you want it to press into the opening in the timing cover, which sets the timing cover right where it should be. (If the timing cover isn't perfectly centered, it'll wear on one side of the seal and then leak.) Once the timing cover's in place, tighten it down so it doesn't move.

Remove the harmonic balancer again and properly torque down the timing cover (be sure to have the power steering pump bracket in place when you do).

Reinstall harmonic balancer, belts, and radiator. Let the new gasket sealant dry for about a day before starting it up.




When you have the cover off, it'll be a good time to inspect your timing gears, especially since your 86 most likely has phenolic gears (which are quieter, but weaker).

 

Good advice, AbandonedBronco! I tried to rep you, but have to spread the wealth.

 

I have seen them with the bolt/stud combo bolts. I would go to j/y and find one like yours and pick your parts. Although it sounds like you might want to remove the t. cover and replace the gasket, then install new bolt.

The bottom line: Whatever works.

I don't mean to split hairs here, but this doesn't sound correct:

The sleeve goes on the vibration dampener, which mounts on the crank. The v.dampener (with the sleeve on it) slips into the seal in the t.cover. It gives you a new surface without a groove caused by the seal riding on the v.d. for untold years. "You have to watch AB. He's been known to toss a few back of a night. Ha ha. That was a joke. He knows his stuff."

While you have it apart, you might want to upgrade to a Saginaw p/s pump.

 

Lol, and I had just got done editing my post to change the word cam to crank. I enjoy my few in the evening.

You're completely right, I wasn't thinking clearly. When you pull the harmonic balancer off, there's a shaft that extends out that slips over the end of the crank. You can see it in the center in this picture:



THAT's where the repair sleeve goes. My bad.

 

I am looking for the torque specs for 94 F150 4.9 L power steering pump pulley?

 

Hi mksanta,
There shouldn't be any torque specs for a power steering pump pulley.
Unless you have something that's not stock, the pulley is a press-on fit.
