Question about harmonic balancer puller tools
Do the pullers advertised on Summit Racing's site work the same way as Kent-Moore harmonic balancer puller U-39046-4? From what i've read, the K-M puller uses a rod that seats against the bottom of the hole in the crankshaft. Is K-M's J-39046 the same puller? Pricing for the K-M puller are insane, between $800-$1,100.
Here are links to Summit Racing's 3 pullers. From what i can tell, all 3 appear the same, come with more or less tooling and all in the same price range.
Thanks in advance, i'm looking forward to your replies.
