Description
Crankshaft front oil seal replacer
Anchor plate for use with 21825577
Adaptor for use with 21825577 (refer
to your nearest Perkins distributor)
Note: The seal is fitted to a depth of 10,20/10,70 mm (0.402/0.421 in) from the front face of the oil seal housing
to the flat front face of the oil seal. If, in service, there is wear in the seal location area of the crankshaft pulley,
oil will continue to leak after a new oil seal is fitted. To repair a worn crankshaft pulley, see Operation 6-5.
To fit an oil seal to a timing case cover that is removed from the engine
1 Clean the oil seal housing. Inspect the new seal for damage. If a scratch can be seen across the lip of the
seal, do not fit the seal.
2 Lubricate the outer circumference of the oil seal with clean engine lubricating oil and enter the seal into the
housing. Ensure that the spring loaded lip of the oil seal is towards the inside of the timing case cover and that
the oil seal is square to the bore of the seal housing.
3 Use a press and the correct adaptor to press the seal into the housing to a depth of 10,20/10,70 mm (0.402/
0.421 in) from the front face of the oil seal housing to the flat front face of the oil seal. Ensure that the timing
case cover is supported correctly, and that excessive pressure is not used to fit the seal, this can damage or
distort the cover.
4 Fit the timing case cover, see Operation 6-2.
