An indis-pensable manual for any engine work and as an engine parts reference

Here’s a simple chart we’ve made to help you with determining its size.

Quick Tips1, 2, & 3: Engine Information I would like to order the correct parts for rebuilding my engine.How do I determine the cubic inch displacement (CID) of my flathead 6?

Installation of, and Cylinder Head Tightening Sequence When installing a cylinder head, always use a new gasket. Make sure the cylinder head and cylinder block are free from carbon and dirt. Inspect your bolts and studs carefully and replace any that are corroded, stretched, thread damaged or stressed in any way. Don’t forget to use sealant on all head bolts and studs before installation. We recommend plumber’s pipe joint compound.

Tighten the cylinder head cap screws in sequence as shown in the illustration (right), by drawing all cap screws and nuts down evenly. Repeat this operation until all screws and nuts are tight. Use a torque wrench and tighten cap screws to 65-70 foot-pounds and stud nuts to 52-57 foot-pounds.

Just a note on machine work when either rebuilding or per-forming a valve job: Make sure you check cylinder head for flat-

ness. Have the head planed if necessary. Its also a good idea to have the head magnafluxed for stress cracks. Check and clean spark plug holes and watch for crossthreaded holes. When installing new spark plugs, always use anti-seize on the threads and hand tighten with a wrench to snug. Do not torque to over 32 foot-pounds.

Quick Tip 4: Engine Oil ServiceRecommendations: Oil is the lifeblood of your engine, so using the correct type & viscosity is just as important as changing it regularly. Back when your Power Wagons was new, it

would have used SAE 30W non detergent. Oil technology has really changed since then, for mild operating temperatures we’d recommend using a 10W30, for artic conditions 5W30 and for hot conditions 20W50 is a good idea. Keep in mind that no 2 flat head six cylinder engines are the same and yours may hold more consistent oil pressure with a particular viscosity or even brand of oil. While you may be tempted to use newer synthetic type or synthetic blend oils, we don’t recommend doing so. Synthetic oils are generally considered good for engines, but the seals, gaskets and tolerances in the old flat head six just aren’t right or tight enough for synthetic oils and you may experience more leaks then normal.

Quick Tip 5: Replacing an Oil Pump Any special procedures required for replacing my oil pump? It’s very important to prime the oil pump prior to installation. Before you start the engine, remove the oil pump and completely submerge oil pump in clean oil. Turn the shaft by hand until there are no more

air bubbles. Reinstall the pump with a new gasket. Fill the engine with fresh oil. Disconnect the coil wire and crank the engine until you have pressure on the gauge. Reinstall the coil wire and start the engine.
