Parts for your 2002 Daihatsu Gran move-Oil seals

2002 Daihatsu Gran Move oil seals — what they do and when to replace them

Oil seals are absolutely fitted to the 2002 Daihatsu Gran Move. Technical sources including the Daihatsu Gran Move/Pyzar workshop manual (Engine Mechanical and Manual Transaxle sections) and the Daihatsu Electronic Parts Catalogue list multiple seals: front and rear crankshaft oil seals, camshaft oil seal, and transaxle/drive shaft (axle) output shaft oil seals, along with differential side seals. These seals keep engine and gearbox lubricants where they belong and stop dust and water getting in.

On a Gran Move, oil seals have a straight‑up job: retain oil around fast‑spinning shafts while the engine and driveline cop a daily hiding. The front crank seal sits behind the crank pulley, the rear crank seal lives between the engine and gearbox, the cam seal sits in the timing end of the head, and the transaxle seals hug the drive shafts. When healthy, they protect bearings, timing components, and clutches from oil contamination and help the engine hold proper oil pressure.

As part of routine servicing, give the seals a once‑over whenever the bonnet’s up for a timing belt, clutch, or driveshaft boot job. Look for fresh oil misting, weep lines, or dirt stuck to oily patches. A few common tells:

• Front crank or cam seal: oil inside the timing cover, flicked oil on the lower covers or crossmember, damp belt area.
• Rear main seal: oil at the bellhousing weep hole or clutch slip on take‑off.
• Transaxle output seals: gear oil on the inner CVs or driveway spots with that distinctive sulphury smell.

If a seal’s leaking, replacement beats topping up forever. On this model, it’s smart to pair jobs: do the front crank and cam seals with the timing belt and front main pulley off
