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 appreciated.
