1994 f 250 7.5 timing chain cover removal
#17
Yep, got I figured out. got the cover off as well. Good news, the broken bolt is sticking out of the block an inch or so...am soaking it in PB and hoping I can slowly turn out tomorrow instead of drilling and extracting.
Scraping old gasket and will make sure I get all my parts in order. Just going to change the timing chain and get a new cover. The sprockets seem ok with good points. Would you suggest these be changed while I am at it? I am thinking the harmonic balancer will be a pain to install. Any suggestions?
Any other things to think of will be greatly appreciated.
Thanks

You'll get new sprockets with the timing chain, or at least you should. The new timing cover should come with a fuel pump block off plate and a plug for the dipstick hole in the top. Be sure they are installed. You should replace the water pump backing plate if you are replacing the cover too. Ford racing makes a new part. You can order it from Summit Racing. To install the damper you can rent a tool from the parts store, or buy a longer crank bolt by an inch or so. You press it on with the bolts. Start with the long bolt, bottom it out, then finish it with the original bolt. Some anti seize on the crank snout should aid in installation.

To the OP, did you damage the timing cover when removing it? Otherwise I don't know why you wouldn't reuse it rather than getting a new one.

I installed the Dorman part when I changed my water pump. It is universal to any year 460, so it has the mechanical fuel pump boss milled and the dipstick hole at the top passenger side location.
As far as replacing, I couldn't properly clean my original up, so I replaced it. Also it's possible for it to corrode through and leak coolant into the block

Don't replace just the chain... do it right and get the entire kit which is the chain and both sprockets. Sheesh.
Don't forget a new front crankshaft seal if your replacement cover don't have one installed already.
Since you have the water pump off, now would be a good time to replace it since it's original. Might as well put in a new thermostat too since it's only a few bucks and then you won't have to worry about it.
Harmonic balancer will go on easy, nothing to worry about. Just tap it back on with a dead blow hammer BUT DON'T hit it anywhere along it's outer diameter. That outside ring is fastened to the inner hub by a rubber ring and if you smack it enough times then you might cause it to come apart.
The hardest part of this job will be that stuck/busted bolt. Get that out and the rest of it should go easily.

Thanks again one and all for the assistance, greatly appreciated given the fact that I am a newby and have a lot of questions. I plan to replace everything mentioned above. A couple of more questions:
The repair manual and posts are referring to removing the fuel pump and plugging the intake and output hoses. Unless I am blind, I do not see a fuel pump any where around the timing chain area...what am I missing. Where is it located? I got the cover off pretty easily. Only a slight obstruction on the lower right and this apparatus is box-like and had a coolant hose attached to it. Additionally, a few posts made reference to a dip stick. Again, I do not see a dip stick in the vicinity...or is this something that I need to pay attention to on a replacement cover and nonfunctional on my application?
Again, thanks for the help and the encouragement. As I start the reassembly process I am sure I will have additional questions.

Your fuel injected truck won't have a fuel pump in that location. Older carbureted engines have a mechanical fuel pump there.
The obstruction you came across on the lower right is the engine oil cooler. It's a heat exchanger which uses engine coolant to cool the engine oil. Prone to failure on these trucks it seems, some of us have removed it to fix or prevent the oil/coolant mixing problem that would happen if the cooler fails internally. Up to you if you want to remove it. You can search on here to find out what to do if you want to ditch it. Pretty easy.
No dipstick on your timing cover... that would be for older engines as well. You must be using a Haynes manual!
Good job getting the cover off... keep us posted.

Thanks for solving this mystery. I did not think I was missing anything. Going to take the night off, get a parts list put together and begin working on that stuck bolt tomorrow after work. One of my sons just loves this big truck and is finding it hard to settle for alternate transportation to school...but, he will have to wait!

Ok...done! thanks for all of your help. Small oil leak though...might see if tightening some oil pan bolts do the trick. If not, might have to take it apart and try again...will go much quicker now that I know what I am doing....boy, finding replacement bolts for the timing chain cover and water pump was sure a royal pain.
