Parts for your 1990 Suzuki Swift-Oil seals

1990 Suzuki Swift oil-seals — what they do and when to replace them

Oil-seals are absolutely used on a 1990 Suzuki Swift. Factory documentation such as the Suzuki Swift Service Manual (1989–1994, G10/G13 engines) specifies crankshaft front and rear oil-seals, camshaft oil-seals, and transaxle drive shaft oil-seals. Suzuki parts catalogues for SA413/AA44 models list these seals by part number, confirming they’re fitted across the engine and gearbox assemblies.

On a 1990-Suzuki-Swift, oil-seals keep engine and gearbox oil where it belongs and stop dust and water getting in. They sit around rotating shafts — think crankshaft, camshaft and the gearbox output stubs — using a spring-loaded lip to hold pressure and keep things tidy. When they harden or wear, oil can weep out, leading to drips on the driveway, clutch slip (if the rear main leaks), or an oily timing belt that can shorten belt life.

These seals aren’t a routine “replace every service” item
