Parts for your 1999 Daihatsu Gran move-Oil seals

1999 Daihatsu Gran Move oil seals

Oil seals are absolutely fitted to the 1999 Daihatsu Gran Move. Factory technical sources for the model (sold locally as the Gran Move and globally as the Daihatsu Pyzar, M100/M110 series) — including the Daihatsu workshop manual and the Daihatsu/Toyota electronic parts catalogue — list multiple engine and transaxle oil seals, such as the front crankshaft seal, rear main seal, camshaft seal, and transaxle/drive-shaft output seals. They’re essential to keeping engine and gearbox oil where it should be.

For this Gran Move, oil seals do the quiet, critical job of holding back oil at rotating shafts. Up front, the crank seal and cam seal sit behind the timing belt covers, stopping oil from weeping onto the belt and pulleys. Down the back of the engine, the rear main seal keeps engine oil from sneaking into the bellhousing. In the gearbox, the drive-shaft (axle) seals prevent transaxle oil leaks where the CV shafts plug in. When these seals age or harden, owners may notice oil mist around the timing covers, a drip from the bellhousing, or wetness at the inner CVs.

As part of regular servicing, it’s smart to:

• Check for oil misting around the timing covers, sump and bellhousing every service.
• Replace the front crank and cam seals whenever the timing belt is off (a common-sense add-on while access is easy).
• Renew axle seals if a CV shaft is removed, or if there’s sweating around the transaxle outputs.
• Inspect the PCV/breather system — excess crankcase pressure can make fresh seals leak.

There’s no fixed kilometre interval for oil-seal replacement
