Specil Service Informtion Grooves in Cylinder Block Cused By Crnkshft Seling Rings Grooves in cylinder lock cused y crnkshft seling rings re not prolem, except if instlling new crnkshft nd the new seling rings on crnkshft do not line up with existing grooves in cylinder lock. If instlling new crnkshft, refer to crnkshft instlltion, Powerhed Ressemly section to determine if powerhed cn e used. Cylinder Bores. Inspect cylinder ores for scoring, scuffing or trnsfer of luminum from piston to cylinder wll. Scoring or scuffing, if NOT TOO SEVERE, cn normlly e removed y honing. If trnsfer of luminum hs occurred, n cidic solution such s TIDY BOWL CLEANER should e pplied to the res of the cylinder ore where trnsfer of luminum hs occurred. After the cidic solution hs removed the trnsferred luminum, thoroughly flush the cylinder ore(s) to remove ny remining cid. Cylinder wlls my now e honed to remove ny glze nd to id in the seting of new piston rings.! CAUTION It crnkcse cover or cylinder lock is to e sumerged in very strong clening solution, it will e necessry to remove the crnkcse cover/cylinder lock leed system from crnkcse cover/ cylinder lock to prevent dmge to hoses nd check vlves.. Thoroughly clen cylinder lock nd crnkcse cover. Be sure tht ll selnt nd old gskets re removed from mtching surfces. Be sure tht cron deposits re removed from exhustports.. Inspect cylinder lock nd crnkcse cover for crcks or frctures.. Check gsket surfces for nicks, deep grooves, crcks nd distortion tht could cuse compression lekges. 4. Check ll wter nd oil pssges in cylinder lock nd crnkcse cover to e sure tht they re not ostructed nd tht plugs re in plce nd tight. HONING PROCEDURE. When cylinders re to e honed, follow the hone mnufcturer s recommendtions for use of the hone nd clening nd luriction during honing.. For est results, continuous flow of honing oil should e pumped into the work re. If pumping oil is not prcticl, use n oil cn. Apply oil generously nd frequently on oth stones nd work re.! CAUTION When honing cylinder lock, remove hone frequently nd check condition of cylinder wlls. DO NOT hone ny more thn solutely necessry, s hone cn remove cylinder wll mteril rpidly. c. Strt stroking t smllest dimeter. Mintin firm stone pressure ginst cylinder wll to ssure fst stock removl nd ccurte results. d.

Stroke t rte of 0 complete cycles per minute to produce est cross-htch pttern. Use honing oil generously. e. Thoroughly clen cylinder ores with hot wter nd detergent. Scru well with stiff ristle rush nd rinse thoroughly with hot wter. A good clening is essentil. If ny of the rsive mteril is llowed to remin in the cylinder ore, it will cuse rpid wer of new piston rings nd cylinder ore in ddition to erings. After clening, ores should e swed severl times with engine oil nd clen cloth, then wiped with clen, dry cloth. Cylinders should not e clened with kerosene or gsoline. Clen reminder of cylinder lock to remove excess mteril spred during honing opertion.. Hone ll cylinder wlls just enough to de-glze wlls.. Mesure cylinder ore dimeter (with snp guge micrometer) of ech cylinder, s shown elow. Check for tpered, out-of-round (egg-shped) nd oversize ore. 4.

NOTE: The weight of n oversize piston is pproximtely the sme s stndrd size piston; therefore, it is not necessry to re-ore ll cylinders in lock just ecuse one cylinder requires re-oring.. After honing nd thoroughly clening cylinder ores, pply light oil to cylinder wlls to prevent rusting. 4 Litre Work/ Cr/ EFI/0 EFI Models Model Litre Work/ Cr EFI/0 EFI Cylinder Block Finish Hone.

Pistons nd Piston Rings IMPORTANT: If engine ws sumerged while engine ws running, piston pin nd/or connecting rod my e ent. If piston pin is ent, piston must e replced. (Piston pins re not sold seprtely ecuse of mtched fit into piston.) If piston pin is ent, connecting rod must e checked for strightness (refer to Connecting Rods, following, for checking strightness).. Inspect pistons for scoring nd excessive piston skirt wer.. Check tightness of piston ring locting pins. Locting pins must e tight.. Thoroughly clen pistons. Crefully remove cron deposits from pistons, with soft wire rush or cron remove solution. Do not urr or round off mchined edges. Inspect piston ring grooves for wer nd cron ccumultion. If necessry, scrpe cron from piston ring grooves eing creful not to scrtch sides of grooves. Refer to procedure following for clening piston ring grooves. CLEANING PISTON RING GROOVES Keystone (tpered) ring grooves! CAUTION Cre must e tken not to scrtch the side surfces of the ring groove. Scrtching the side surfce of the ring groove will dmge the ring groove.. Use ristle rush nd cron remover solution to remove cron from side surfces.. A tool cn e mde for clening the inner dimeter of the tpered ring grooves.

Overheting: Overheting is visile s luish ering surfce color tht is cused y indequte luriction or excessive RPM.. Rust: Rust formtion on ering surfces cuses uneven pitting of surfce(s). - Pitting. Splling: Splling is the loss of ering surfce, nd it resemles flking or chipping. Splling will e most evident on the thrust portion of the connecting rod in line with the I em.

Under these conditions, the crnkshft journl is hmmered y the connecting rod. As ignition occurs in the cylinder, the piston pushes the connecting rod with tremendous force, nd this force is trnsferred to the connecting rod journl. Since there is little or no lod on the crnkshft, it ounces wy from the connecting rod. The crnkshft then remins immoile for split second until the piston trvel cuses the connecting rod to ctch up to the witing crnkshft journl, then hmmers it.
