Several people on the TDR website showed interest in learning more about the work involved in replacing a broken timing gear housing from damage caused by the upper.

Several people on the TDR website showed interest in learning more about the work involved in replacing a broken timing gear housing from damage caused by the upper dowel pin working its way loose. You first remove the bumper, fan, radiator and loosen the A/C condenser. It is possible to remove the intercooler without breaking the A/C lines and losing the charge of Freon as shownbelow. You must be very careful though. The harmonic balancer and electrical sensor are being removed here. This illustration shows the timing cover with the idler pulley removed. The crack caused by the dowel pin is always under the idler pulley and cannot be seen until it is removed.

This crack is the first sign of internal damage. You then remove the case cover and expose the internal timing gears. This is a good time to rotate the engine until the timing marks on the camshaft and crankshaft gears line up. You can see by the ‘V’ mark on the camshaft gear that this engine needs to be rotated almost a full 360° to align with the white mark on the crankshaft gear at the two o’clock position. With the cover removed you can see more of the damage caused by the dowel pin.

On this particular engine, no visible damage was done to the timing gears. Now the easy part is over with. Removing the timing houseing is a bit more involved. The vacuum and power steering pump assembly can be removed with two bolts.

The vacuum pump gear does not need to be removed, it slides out through the back of the housing. Four nuts that hold the injection pump to the timing housing must now be removed. The two outside nuts are easy to access, but the inner two are difficult. Below is a picture of the inner two nuts. A severely bent hand wrench will access the top nut. The bottom nut requires more imagination. The next step is to remove the camshaft.

This requires removing all six valve covers, rocker assemblies and push rods. There obviously isn’t room to extract the pushrods from the #5 and #6 cylinders. Dodge has conveniently left two holes in the cowl of the truck just for this purpose. The holes are filled with two rubber plugs. To gain access to these plugs, the windshield wipers and plastic cowl must be removed. You will need twelve 1/2″ dowel rods cut one foot long for the next procedure. Each rod needs to be tapered down to a sharp point.

Stellar Phoenix Mailbox Exchange Recovery Serial Number. Begin the taper 1″ from the end of the rod. Now cut a 1″ slit in that taper.

You then drive the dowel rod into the tappets and pick them up off the camshaft. A rubber band will hold the dowel rods up and keep them from falling back down. It’s very important for the dowel rods to be secured to the tappets firmly. The camshaft is likely to hit the tappets while being removed and reinstalled. If one of the tappets falls off the dowel rod, you will need to remove the oil pan to get it out! Now you can remove the camshaft.
