Machined from billet aluminum with steel components where needed, the tools mimic the harmonic balancer to locate seals against the crank snout so covers can be tightened in the correct position before final assembly. Using the right installer keeps seal bores and crankshaft surfaces aligned, simplifying rebuilds and reducing the chance of leaks caused by off-center covers.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool center the timing cover during installation?\u003c\/h3\u003e\n\u003cp\u003eThe alignment adapter slips over the crankshaft snout and simulates the balancer’s outer diameter so the cover’s seal bore nests concentrically around the crank. With the tool in place you can loosely position the cover, verify alignment to the oil pan, then torque the bolts to specification while the cover remains centered.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLarge and small ends to fit different crank snout profiles\u003c\/li\u003e\n  \u003cli\u003eTwo 180° keyway slots to accommodate single or dual keyway cranks\u003c\/li\u003e\n  \u003cli\u003eSlightly oversized outer diameter to engage the oil pump opening for better centering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat engine families and displacements is this kit compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis installer set was made specifically for GM LS-series platforms, covering commonly used generations and castings from small-block style LS engines to truck-based LQ variants.

Alternatively, install the cover loosely, use the large end over the snout to verify alignment to the oil pan, then torque the bolts to spec and finish with the balancer lip seal.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMethod A: seal into cover, loose bolts, small-end tool, torque to spec\u003c\/li\u003e\n  \u003cli\u003eMethod B: loose cover, large-end tool, align to oil pan, torque to spec\u003c\/li\u003e\n  \u003cli\u003eFinish by installing the harmonic balancer and verifying seal orientation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This BILLFARO alignment kit is built for professional and home engine builders, automotive technicians, and performance enthusiasts who rebuild or service GM LS engines and want a repeatable, precise way to align timing covers and lip seals. If you work on LS-series engines and value accuracy, reduced rework, and lower leak risk, this tool simplifies cover installation and speeds up reliable assembly.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this fit LQ4 and LQ9 truck engines?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
