It is necessary to replace new oil seals if you find oil leakage.So here in this post,car-auto-repair.com show you guide on how to renew rear oil seals for Perkins 1000 series engine.
To renew the rear oil seals
1 Remove the seals from the housing with a suitable tool used as a lever. Ensure that the seal housing is not damaged. Do not try to press the seals out of the housing as there is a shoulder in the housing (B).
2 Clean thoroughly the oil seal housing. Inspect the oil seals for damage. If only a small scratch can be seen across the lip of the seal, do not fit the seal.
Note: Before the oil seals are fitted into the housing ensure that the correct seal is fitted to the correct side of the housing. Each of the seals has an arrow on the flat face of the seal. This arrow indicates the correct direction of shaft rotation for the seal, see (B2) and (B3).
3 Lubricate lightly the outer circumference of the front oil seal and the bore of the housing for the front seal with clean engine oil.
4 With the flywheel side of the seal housing on a suitable support, press the new front seal into the housing. Use a suitable tool which will apply pressure only to the flat inside face of the seal.
Caution: Use only enough pressure to ensure that the flat face of the seal is against the shoulder in the housing. Too much pressure could damage the shoulder.
5 Lubricate lightly the outer circumference of the rear oil seal and the bore of the housing with clean engine oil.
6 With the engine side of the seal housing on a suitable support, carefully press the rear oil seal onto the shoulder in the housing with the same tool as for the front seal. Ensure that the seal is against the shoulder in the housing.
Caution: The rear oil seal must not be fitted if the engine is to be operated before the oil is added to the flywheel housing. The seal must be fitted with the seal housing in situ after the engine has been run.
