What years does this exploded engine diagram cover?

The figure caption states it applies to 1969–81 vehicles: 'Fig. 31 Exploded view of engine components (part 1)—1969–81 vehicles.'

What chain rating does the manual recommend when lifting the engine?

It warns to be absolutely sure the chain has a weight rating greater than the weight of the engine, and if possible to use chain rated at least at 1,000 lbs., since an inferior chain could fail.

Can the engine be left hanging on the hoist after removal?

No. The manual warns not to allow the engine to hang from the engine hoist for an extended period of time; it should be mounted on the floor or on an engine stand.

How many numbered components are shown in the exploded view?

Callout balloons numbered 1 through 43 identify individual engine parts such as the valve cover, intake manifold, cylinder head, camshaft, piston and rod, crankshaft, and bearings, though the parts legend is not printed on this page.

What should be attached to the engine for lifting if it lacks lifting brackets?

The text says most engines have lifting brackets bolted to the intake manifold; if not, remove the valve covers and a center head bolt from each cylinder head and attach the lifting apparatus to the cylinder heads, securing with the head bolts.

This is a scanned page from an automotive repair manual showing Figure 31, an exploded view of engine components (part 1) applicable to 1969–81 vehicles. The illustration depicts a Chevrolet-style small-block V8 top end and bottom end broken into individually numbered parts (callouts 1 through 43), including the valve cover and gasket, intake manifold and gaskets, cylinder head and head gasket, rocker arms, pushrods, valve springs and valves, camshaft with bearings/journals, piston with rings, connecting rod, cylinder block, crankshaft, main bearings and bearing caps, and associated bolts and fasteners. No legend identifying each numbered part appears on this page (the key is presumably on a companion page). Surrounding body text covers engine removal procedure, including two safety warnings: use a lifting chain rated greater than the engine's weight (at least 1,000 lbs.) and do not let the engine hang from the hoist for extended periods — mount it on the floor or an engine stand. Additional partially legible text discusses removing the starter, flywheel splash shield, converter-to-flywheel bolts on automatics, clutch cross shaft removal on manual transmissions, and draining the transmission before driveshaft removal. Much of the marginal text is cut off or too faded to read fully.
