Description

Do you hate having to use a hammer and an expensive special tool to install a front crankshaft seal (Front main seal)?  Simply put the new seal on the tool and use the harmonic balancer bolt to press the seal into place. 

Print with a high infill (I printed it at 100% with petg). 

Using this should prevent seal damage or improper installation. 

Please let me know how it works for you and upload photos!
