V d\u00f4sledku opotrebenia val\u010dekovej re\u0165aze sa zv\u00e4\u010d\u0161uje rozstup \u010dl\u00e1nkov, \u010do sp\u00f4sobuje jej predl\u017eovanie (CZPT er).

Pri modern\u00fdch re\u0165aziach je nezvy\u010dajn\u00e9, aby sa re\u0165az (okrem bicyklov\u00fdch) opotrebov\u00e1vala a\u017e do zlomenia, preto\u017ee opotrebovan\u00e1 re\u0165az vedie k r\u00fdchlemu opotrebovaniu zubov ozuben\u00fdch kolies, pri\u010dom kone\u010dn\u00fdm zlyhan\u00edm je strata v\u0161etk\u00fdch zubov na ozubenom kolese. Ozuben\u00e9 koles\u00e1 (najm\u00e4 men\u0161ie z dvoch) trpia \u0161kr\u00edpav\u00fdm pohybom, ktor\u00fd dod\u00e1va poh\u00e1\u0148anej ploche zubov charakteristick\u00fd h\u00e1kovit\u00fd tvar. (Tento efekt sa zhor\u0161uje nespr\u00e1vne napnutou re\u0165azou, ale je nevyhnutn\u00fd bez oh\u013eadu na starostlivos\u0165). Opotrebovan\u00e9 zuby (a re\u0165az) nezabezpe\u010duj\u00fa plynul\u00fd prenos rozvodovej re\u0165aze a to sa m\u00f4\u017ee prejavi\u0165 hlukom, vibr\u00e1ciami alebo (v automobilov\u00fdch motoroch pou\u017e\u00edvaj\u00facich rozvodov\u00fa re\u0165az) zmenou \u010dasovania zapa\u013eovania pozorovanou kontrolkou rozvodovej re\u0165aze. V t\u00fdchto pr\u00edpadoch by sa mali vymeni\u0165 ozuben\u00e9 koles\u00e1 aj re\u0165az, preto\u017ee nov\u00e1 re\u0165az na opotrebovan\u00fdch ozuben\u00fdch koles\u00e1ch nevydr\u017e\u00ed. V menej z\u00e1va\u017en\u00fdch pr\u00edpadoch je v\u0161ak mo\u017en\u00e9 zachr\u00e1ni\u0165 v\u00e4\u010d\u0161ie z dvoch ozuben\u00fdch kolies, preto\u017ee v\u017edy to men\u0161ie trp\u00ed najv\u00e4\u010d\u0161\u00edm opotrebovan\u00edm.

Pred\u013a\u017eenie re\u0165aze v d\u00f4sledku opotrebovania sa vypo\u010d\u00edta pod\u013ea nasleduj\u00faceho vzorca:<\/p>\n

\u00a0<\/p>\n

M = d\u013a\u017eka po\u010dtu meran\u00fdch \u010dl\u00e1nkov<\/p>\n

P = V\u00fd\u0161ka t\u00f3nu<\/p>\n

V priemysle je be\u017en\u00e9 sledova\u0165 pohyb nap\u00edna\u010da re\u0165aze (\u010di u\u017e manu\u00e1lneho alebo automatick\u00e9ho) alebo presn\u00fa d\u013a\u017eku hnacej re\u0165aze (jedn\u00fdm z pravidiel je vymeni\u0165 val\u010dekov\u00fa re\u0165az, ktor\u00e1 sa pred\u013a\u017eila 3% na nastavite\u013enom pohone alebo 1,5% na pohone s pevn\u00fdm stredom). Jednoduch\u0161ia met\u00f3da, vhodn\u00e1 najm\u00e4 pre pou\u017e\u00edvate\u013eov bicykla alebo motocykla, je pok\u00fasi\u0165 sa odtiahnu\u0165 re\u0165az od v\u00e4\u010d\u0161ieho z dvoch ozuben\u00fdch kolies a z\u00e1rove\u0148 zabezpe\u010di\u0165, aby bola re\u0165az napnut\u00e1.

Ak sa probl\u00e9m ignoruje, d\u00f4jde k po\u0161kodeniu CZPT. Opotrebenie CZPT tento efekt ru\u0161\u00ed a m\u00f4\u017ee maskova\u0165 opotrebovanie re\u0165aze.<\/p>\n
