Question about 1986 Ford F 250
Broken Timing Chain. If you do this repair yourself it is not too expensive. If you have never done one you may need to get some loaner tools at Autozone or Oreillys. Or you can call for estimates and see if the shop will throw in a free tow or use an Autoclub or Insurance Tow benefit.
The Timing chain cover is the housing in front of the block. You will need to pull the crankshaft pulley off to get the housing apart. There is a large bolt holding the pulley on and sometimes you need a pulley puller to remove the pulley. The Water pump and several brackets will have to be moved out of the way. If the Distributor goes through the front cover, the Distributor will need to be pulled. When you align the timing marks on the 2 gears, you will need to reinstall the Distributor with the rotor pointing to Number 1 cylinder.
When you need to remove the crankshaft seal, do it after you clean off the gasket. You want to look at the ridges on the seal. Yours may be possible to install backwards, yours may or may not be that type.
Put a little lubricant on the seal, remember to align the timing marks and put some lube on the chain. Sometimes it helps to use different colors of paint to keep the waterpump and timing cover bolts in their proper position. Some bolts are different lengths and the motorblock and housing have matching thickness. You can use cardboard and make a rough outline of the bolt pattern and insert the bolts into the cardboard while you are disassembling the motor.
