Jeep TJ Build - Jeep 53 - Replacing the front crank seal and harmonic balancer

In this video I start off replacing the harmonic balancer. After I get it off I realize the front crank seal should be replaced as well. I show how to do it following the factory service manual with the timing chain cover installed. Then I forgot to deal with a bolt behind the balancer, so I take it off again and deal with the bolt before re-installing it. I also show a shop hack for torquing the crank bolt to 80 ft lb.
When you use a link below to purchase from Amazon you pay the same amount and I receive a small referral fee. The fees help offset the cost of my projects and this channel. I appreciate your support. Thank you.
Parts and tools used:
Seal Puller (old school) amzn.to/44xncKY
Lisle puller that did not work for me: amzn.to/3Dn44nb

Wood screws is what I use to pull old seals
