Vigor oil pan replacement

This is not a simple project.

I haven't done it but I've been reading the Honda Motor Manual about it.

Oil pan is attached to the differential (and the differential is attached to one of the two drive shafts and the intermediate shaft), so after attaching an engine hoist to the engine hoist bracket, support the transmission, draining the engine and differential oil, you'll have to remove, sequentially;

1. The wheels

2 Both driveshafts(and all the steps required for axle job, ie. ball joint, damper forks)

3. Transmission mount(about 6 bolts involved, 40 and 47 ft -lbs)

4.1 33 mm(58 ft-lbs)Extension shaft/secondary gear sealing bolt (to get to the extension shaft)

4.2 Extension shaft(need a special tool)

5. Engine mount damper and left engine bracket

6. Intermediate shaft

7. Differential (and the Power Steering speed sensor attached to it)

8. Oil pan inner pipe

Hopefully I cover all the important steps

If you are not a mechanic like I'm(not), I strongly suggest the Honda very own manual(about 70$) and study what drives what. You'll see that two driveshafts that drive the wheels are driven by a differential carrier that's driven by a pinion gear(in the differential assembly) Only one of the driveshaft is driven directly by the differential carrier while the other is driven throgh an intermediate shaft which is driven by the differential carrier. The pinion gear is driven by a secondary gear in the transmission by means of an extension shaft. And the secondary gear is driven by the countershaft of the tranny itself.

So there are 3 shafts that attach to the differential. One is "to drive" the differential(the extension shaft) and the other two shafts, which drive the wheels, are "driven by" the differential ( one of the two driveshafts and the intermediate shaft). All these three shafts need to be detached from the differential.

If you are doing on the floor like me, the job will be harder, esp the 33 mm bolt that cover the access to the extension shaft. If your car is drivable, I'd first take it to a near by shop and let someone there loosen the 33mm bolt and the transmission mounting bolts(then lightly retighten them), but I would not drive it far after this( and not on highway).

Ps. check YouTube on extension shaft removal. It's for Acura Legend, not Vigor, but you can get the idea.
