GMC Jimmy Camshaft
Camshaft used in GMC Jimmy cars helps to control the intake and the exhaust valve which helps in the regulation of the air/fuel mixture getting into the combustion chamber. These camshafts can be block mounted or cylinder head mounted depending on the type of engine it has, OHV, SOHC, DOHC and the types of valve actuation mechanisms in it. The camshaft should be synchronised with the crankshaft to meet the right specifications for the proper functioning of the camshaft. To achieve the optimal result, new performance camshafts can be fitted to the engine depending on certain modifications and purposes. Lift, duration, and the lobe separation angle do affect air flow, power and idle characteristics. Probability and performance camshafts are a variation of the standard ones and have the ability to open the valves more and for more time contributing to increased HP at high RPM. The decision about camshaft should involve such parameters as compression ratio, type of transmission, and weight of the car to provide the required performance characteristics.
Each OEM GMC Jimmy Camshaft 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.
GMC Jimmy Camshaft Parts Questions & Experts Answers
- Q: What are the steps involved in inspecting and replacing the camshaft and Camshaft Bearing on GMC Jimmy?A: After removing the camshaft from the engine, clean it with solvent and dry it, then inspect the bearing journals for uneven wear, pitting, and evidence of seizure; if damaged, both the camshaft and bearings will need replacement. Measure the inside diameter of each camshaft bearing, taking two measurements at each bearing, and subtract the bearing journal diameters from the corresponding bearing inside diameter measurement to obtain the oil clearance; excessive clearance necessitates new bearings. Camshaft bearing replacement requires special tools and expertise, so it is advisable to take the block to an automotive machine shop. Check the camshaft lobes for heat discoloration, score marks, chipped areas, pitting, and uneven wear; if the lobes are in good condition and the lobe lift measurements are as specified, the camshaft can be reused. Good used roller lifters can be reinstalled with a new camshaft, and while the original camshaft can be used if new lifters are installed, it is recommended to replace both together, especially for high-mileage engines. For V6 engines, if the balance shaft is to be removed, the balance shaft gear bolt should be removed before the timing chain to hold the shaft while loosening the bolt. Remove the two bolts and the balance shaft retainer at the front of the block, then use a slide-hammer threaded into the front of the balance shaft to knock it out. Inspect the balance shaft and measure the bearing journal diameters; if measurements exceed specifications, replace the balance shaft, bearing, and bushing as a set. The rear bushing, similar to a camshaft bearing, must be installed by a machine shop with the proper tools and alignment. Inspect the balance shaft drive gear and the balance shaft driven gear for signs of wear, pitting, broken teeth, or rough operation, as both gears are serviced only as a set.
