Good day everybody. My 05 Excursion has sprung a leak on the front crank seal. Has anybody changed one? How hard is this to do? Looks like I would need a special tool to install the wear sleeve. I’m pretty handy but it’s always nice to talk to people that have actually done one before. Thanks
Several ways of installing one. It’s a wide wear sleeve, so there is a lot of variabilities that can be tolerated.
The real expensive tool which installs both the wear sleeve and seal.
The cheaper hammer tech tool for just the wear ring that set its depth. Old school tech for the seal in the cover on a bench, also hammer tech.
Use the harmonic balancer to push the sleeve on with the old bolts after light taps to start the wear sleeve on the crank. Hammer tech again with the seal and cover on a bench.
I’ve done one and three on several engines.
If there already is a wear sleeve on it, I'd check to see how worn it actually is. They do not wear as easily as the crank nose.
Thanks for the help guys. I think I might get a seal and an Oring for the pump cover. Take the cover off and install a new seal. I’ll maybe set the seal depth a different than it was so it rides on a new spot on the sleeve. Seems like that would be the cheapest and easiest
Yeah, a chisel is not the way to expand the sleeve.
J, depending on how deep the sleeve was installed, you may or may not have room to do that.
This is how mine was and what the used crank surface looked like underneath.
Using a sharp chisel is not the way to take it off. I did what I've seen done for 30 years on axle shafts in fleet garages, and what we did in my test facility. Use a flat hammer, ball hammer, or a rounded surface to tap (I'm using the word tap) around the ring to dimple and expand the sleeve enough to slide it off. It took me about 5 minutes.
It's a method approved by Timken, it works, just don't go neanderthal. This guy is way more aggressive than I was .... on two crankshafts.
Jack I did not spend that much for the kit I got that has all the engine tools in it.
I think I paid the guy that was selling off all the tools he had been storing in a warehouse for a few years.
I know I paid more for the transmission tool set.
Here is a guy using the balancer to install the seal.
