Adjusting
If an insufficient or an excessive distance is measured, proceed as follows
If equipped, remove vacuum hose -2- to air guide hose.
Disconnect air guide hose -1- at throttle valve control module -J338-.
Scheme 389
Disconnect mass air flow (MAF) sensor -G70- electrical connector -3-.
Unbolt upper section of air filter housing -arrows-.
Remove filter element.
Pull off air guide cover -1-, disengage clips sideways to do so.
Scheme 390
Unclip air duct -2-.
Remove lower section of air filter housing -arrows-.
Scheme 391
Remove air filter housing bracket -arrows-.
Scheme 392
Secure shackle 10-222 A/12 at right rear engine lifting eye.
Scheme 393
Position 10-222 A with adapters 10-222 A/3 on fender attachment edge.
Engage spindles at lifting eye or shackle.
Raise engine slightly with spindles even.
Remove subframe mounting bolts at engine -arrows-.
Scheme 394
Remove subframe mounting bolts at transmission -arrows-.
Scheme 395
Replace all 5 bolts in succession (if not already done when installing engine) and hand tighten.
Loosen left and right support arm bolts approximately 2 turns.
Using a pry bar between the engine support -4- and engine mount -1-, move the engine so far until the following dimensions are set
- Both bolts -2- must be parallel to edge of support arm -3-.
- A distance of -x- = 16 mm must be present between engine mount -1- and engine support -4-.
Note. Distance -x- = 16 mm can also be checked with a suitable cylindrical rod.
Tighten engine-side assembly mounting bolts.
On transmission side, make sure edges of support arm -1- and transmission mount -2- are parallel.
Scheme 396
- Dimension -x- same size on both sides of bracket.
Tighten transmission-side assembly mounting bolts.
Further installation is in reverse order.
