Hello folks. I have to R&R the press-fit Romac SFI harmonic balancer on my 482” BBB, but all I have is a generic wheel puller. Rather than removing it with my puller and then renting or borrowing an installer, I want to purchase a good quality harmonic balancer remover/installer kit for this engine. The kit must include a ¾-16 adapter and must be capable in installing the press-fit Romac balancer. Summit.com lists (and has in stock) a few universal-type installers/removers for GM engines (not including LS/LT engines) with prices ranging from $75 for a Proform kit #66514 (that’s torque limited to 150#) to $277 for a Moroso MOR-61743 kit (for "Buick" and a number of other brands), and so on. While I love the idea of a bargain (i.e., Proform), I’m more interested in a good quality product. Right now I'm about ready to call the Moroso tech line to verify that the "Buick" adapter in their kit is actually 3/4-16" before ordering their kit from Summit. Before I do, any recommendations or comments? As always, thank you in advance for your help.
My installer is front snapon......has multiple thread adapters. I think 10 or so different sizes. Does a great job at the installing of these tighter dampners like our buicks and even bbc. My snap on puller stripped out after a few years but my cheap harbor freight unit looks the same with all the same threads is working great. I can say for removal tool I like ones that has the blank hole in the middle torque down screw.....mine has this and has about 4 different length steel rods to bottom out in thread hole of the crank to keep the removal tool from messing up the crank snout/threads
Which is one of the great pitfalls of our BBB's design for performance usage. But when your engine peaks at 4600 rpm, harmonics are usually not a problem. Which is why the factory did what they did. So if your building a 270HP smogger, go ahead and don't bother with a dampener that actually works just throw that sloppy stock one back on. I see more rpm related issues with factory or reproduction factory balancers.. so much so that about 10 years ago, I switched the entire stroker performance lineup to an SFI balancer, and every one of those is press fit. Without being press fit, it's effectiveness is compromised. JW
I like the looks of this Kit Dan.. https://www.speedwaymotors.com/Spee...QkvdyRldlxJXiC2nXtDP1XfHG90yGDDYaAg6NEALw_wcB JW
