Walterscheid | PTO Cam Type Cut-Out Clutch Retaining Ring | 150 × 5 mm | 159524
Walterscheid 159524 is a genuine PTO cam type cut-out clutch retaining ring, OEM 1159524, used in compatible Walterscheid K64 & K68 clutch housings. This internal retaining ring installs in the machined groove inside the clutch housing and retains the clutch hub, supporting disc and related internal components in their correct axial position.
The ring is manufactured to the DIN 472 internal retaining-ring standard and has a nominal size of 150 × 5 mm. The 150 mm designation corresponds to the nominal housing bore size, while the retaining ring itself has a nominal 5 mm thickness.
This 5 mm retaining ring is used with compatible newer reinforced K64 clutch housings designed around the thicker retaining-ring groove. Walterscheid specifically lists OEM 1159524 in K64/22–24 HQ clutch assemblies at assembly position 9.2. Earlier K64 housings may instead use the thinner 150 × 4 mm retaining ring 364499 / OEM 1364499.
Before ordering, verify the original Walterscheid OEM number and measure the internal retaining-ring groove in the clutch housing to confirm that the 5 mm ring is correct for your assembly. Do not select the retaining ring by clutch series alone, since housing revisions can use different groove and ring thicknesses. Part 159524 corresponds to genuine Walterscheid OEM 1159524.
