Front crank seal

[Puddle Jumper 2.0]

My 07 has started to leak a bit around the front crank seal behind the harmonic balancer. Should be pretty straight forward, just wondering about special tools for balancer removal. Does anyone have any suggestions on tools and tricks??? Thank you!

For the puller you can use, I purchsased because having three different legs;

I just changed a timming chain tensioner and used these two tools. If you will do it insitu, it is very tricky to put the puller on blind! You have to be good with your hands, to hook the three legs to the three lugs. Stay calm do not loose patience. I did my whole job in about 10 hours outside here in southern Quebec. Forgot to mention, I went all the way up to the timming chain cover to change a chain tensioner.

I bought this

GEAROLL PULLER

and this

GEAROLL INSTALLER

And because I'm not 100% sure the crank seal is the issue, I also bought this

FELPRO TIMING COVER GASKET SET

just in case it turns out to be the cover. This set also includes the crank seal which I'm going to need either way. I'll be doing this job this weekend.

I just did mine yesterday. As eagle1one said, it's a little tricky getting the 3 arms of the puller on, not bad though. The hardest part for me was getting the old seal out. I ended up using a screwdriver and popping it out. Also, take your time tapping in the new seal. I used a big socket and gentle taps. Really not a bad job to do.

I had 151,000 miles on my harmonic balancer and it had a noticeable groove where the seal had been. I ended up getting a new one at Napa. No more leaks.

You will need the special tools to do the job. Still much cheaper than having someone else do it at a shop.

If you happen to remove the entire timing cover, and have not changed your coolant on a regular schedule, then you may want some aluminum-filled epoxy. Note: Removing the cover is not necessary for a crank seal, only the use of a 3 jaw puller and a long reach pulley installer. Why aluminum epoxy? Because if the coolant was way too old it becomes acidic and likes to erode the aluminum cover behind the formed o-ring seals. Not every time, just sometimes. I used Smooth On brand Metal Set A4 (6oz version). I had to gouge out the oxidized and crystalized aluminum decay until it was clean and bright (well, bright for cast aluminum) then literally "smooth on" some epoxy so the o-ring would be on a flat, smooth surface again. Of course I waited a few hours for it to set enough before reassembly. It was hours and hours before I would be far elong enough to refill the coolant. Alumimum epoxy products out there: Star Brite Epoxy Aluminum Putty Stick - 87004, Mastercool Alum Bond Aluminum Repair Kit 90935-12, and QuikAluminum Aluminum Reinforced Epoxy Putty Stick.
