I'm preparing to replace the timing chain on my '99 Dodge Ram 5.9 gas
engine, which also means replacing the front crankshaft oil seal. I have a
generic oil seal installation tool kit that looks like it will work, but the
depth of the various size disks is only about 1/4 inch. The service manual
calls for Dodge Special tool 6635 with a depth that looks to be about 2
inches and the manual says to use the vibration dampener bolt in conjunction
with the special tool to draw the seal into position.
I have not started to remove parts yet, so I don't know if I should use the
special tool, or if I can use my generic set with either a shorter bolt or
with the vibration dampener as a spacer in conjuction with the stock bolt.
I realize that the depth of the special tool will provide a more square
seating provided the depth of the hole in the timing chain cover is greater
than the depth of my generic set.
Any thoughts regarding whether I should buy the special tool would be
