TORQUE CONVERTER, CHECKING

Check the torque converter hub -arrow- for wear grooves.

Scheme 351

Note. The torque converter must be replaced if it is damaged or faulty.

Special tools and workshop equipment required

1. Extractor T40176
2. Grease for clutch disc shaft splines G 000 100

Removing

Remove the left flange shaft. Refer to LEFT FLANGE SHAFT .

Secure the T40176 to the torque converter -A- with the nut -B-.

Scheme 352

Rotate the T40176 upward.

Scheme 353

Note. To prevent the torque converter from tilting, counterhold it underneath as illustrated. Ignore -arrow-.

Remove the torque from the input shaft -arrows- without tilting the converter.

Set the torque converter down carefully, for example on the workbench.

Installing

Install in reverse order, paying attention to the following

Always clean the torque converter bell housing in the area where the differential is accessed -arrow A- and the shaft seal -arrow B-.

Scheme 354

Note. Replace the shaft seal between the differential and transmission housing -arrow B- if it is damaged. Refer to FRONT FINAL DRIVE OVERVIEW .

Fill the space between the sealing- and dust lip half way with sealing grease G 052 128 A1.

Clean the splines on the input shaft -2- and the torque converter, remove any corrosion and apply a very thin layer of clutch disc spline grease G 000 100 to the splines. Remove any excess grease.

Scheme 355

Slide the torque converter carefully onto the input shaft -arrow- using the T40176. Be careful not to tilt the converter when sliding it on.

Remove the T40176 from the torque converter -A-.

Remove the nut -B-.

Install the left flange shaft. Refer to LEFT FLANGE SHAFT .
