GMC Jimmy Variable Timing Sprocket

The Variable Timing Sprocket for GMC Jimmy optimizes camshaft timing so the engine breathes at just the right moments for more power throughout the entire RPM range. This component fits on the camshaft sprocket assembly and works with a matched assembly of chain and crank gear to replace factory fixed wheels when the timing set gets serviced. Due to small mark misalignments of two or three degrees robbing up to 50 horsepower, the Variable Timing Sprocket allows builders to fine-tune alignment beyond simple mark to mark assembly. The Variable Timing Sprocket can fine-tune the cam position in measured steps through a multitude of keyways that are machined into the crank gear, plus optional offset bushings or elongated cam slots. Advancing opens intake valves earlier to bump low-end torque useful for towing. Retarding pushes the power higher up in the rev range, making for more spirited runs on the highway. The Variable Timing Sprocket should always be changed as a set (chain, guides, and tensioner) in order to keep wear patterns uniform. Earlier GMC models relied on single position sprockets, but later Jimmy editions adopted the adjustable Variable Timing Sprocket, giving GMC and Jimmy owners the flexibility to tailor performance without internal engine redesign.

Each OEM GMC Jimmy Variable Timing Sprocket we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

    Q: How to remove and install the Timing Chain, Timing Cover and Variable Timing Sprocket on 2.2L four cylinder engine on GMC Jimmy?
    A:
    Begin by removing the cover, then isolate it from the negative battery cable. After that, remove fan shroud upper part, drive belt, fan/clutch assembly, water pump pulley, crankshaft pulley and hub. Remove the drive belt tensioner bracket and Timing Cover-to-engine block bolts next. Utilize a gasket scraper to erase any old gasket material and clean any of the sealing surfaces. To remove the timing chain; temporarily install crankshaft pulley hub and bolt; rotate crankshaft to align timing marks on crankshaft and camshaft sprockets; push back timing chain tensioner plunger and insert pin to retain plunger; using prybar holding engine while removing camshaft bolt; carefully prying camshaft sprocket off. Check for damage or wearout on timing chain and sprockets before replacing if necessary. Mesh new timing chains with camshafts; put them into engagement with crankshafts at their sprocket's teeth; aligning timing marks; installing tightening camshaft sprocket bolt; releasing tensioner; lubricating chain/sprocket; rotating engine to check alignment of timing marks; applying RTV sealant to oil pan sealing surface; finally securing front cover using new rubber seal.
