    Q:
    How to remove the camshaft and camshaft bearings in Buick Century and Regal? Posted by Customer
    A:
    When starting to remove the camshaft and camshaft bearings in 196, 231, 252, and 350 Buick Engines, first remove the timing chain and cover. Before pulling out the radiator, unfasten the condenser if your engine is air conditioned. Next carefully dismantle hydraulic lifters to ensure no bearing surface damage while sliding the camshaft forward. The installation of a puller containing puller screw, expanding collet and back-up nut should be done for easy removal of camshaft through removal of the front bearing. Unlike other bearing, this front one can be extracted with a spacer. Reverse these steps during installation ensuring that we replace the whole set of camshaft bearings. In comparison to above mentioned instructions on removal of camshafts; for engines such as 265 or 301 Pontiac Engines which also have similar procedures like intake manifold lifter pushrod rocker arms etcetera should all be removed after removing cam shafts and shaft bearings -particularly where there is A/C in cars; evacuate the system then take away condenser. To perform this task correctly, there are specific tools that are used to remove bearings but their order is different from how they were installed. After lubricating the camshaft and aligning timing marks we put it back together with distributor in place. The rest are placed back on opposite order. Disconnection of battery; draining and taking off radiator; disassembly of different parts such as intake manifold valve lifters timing chain sprockets among others will be involved in dismantling process of these engines such as those in Oldsmobile Gasoline Engines 307,350 and 403.Very carefully extract the camshaft; replace them together with lubricating both them and the beam before reinserting it. Put distributor back while ensuring alignment with timing marks on it so that it rotates around crankshaft at proper instant when engine is running again. Assemble all pieces backwards and make sure to observe some steps and precautions. Removing the camshaft necessitates removing the injection pump drive and driven gears, intake manifold, valve lifters, then retiming of the injection pump for 263 and 350 Oldsmobile Diesel Engines. In case of air conditioning system, it should be discharged. Then remove camshaft and gears ensuring correct alignment and if necessary replace both gears. After lubricating the camshaft and bearings slide it back carefully into place. It is now time to re-align and install gears; injection pump with others in reverse order as per instruction on end play adjustment as well as timing.
