Re: [MBZ] Draining Torque Converter
Someone has gone before you. Your bell housing casting is broken because someone has used the “ribs” as a fulcrum for a screwdriver against those little raised “tabs” you can see on the torque converter. That works, too, when ring gear teeth can’t be accessed. -D > On Apr 18, 2019, at 1:22 PM, Craig via Mercedes wrote: > > On Sat, 13 Apr 2019 19:57:42 -0400 Dan Penoff via Mercedes > wrote: > >> Or…. >> >> Long flat bladed screwdriver.

Re: [MBZ] Draining Torque Converter
Nearly all cars I’ve done this on I’ve been able to turn the engine from below. A deep 27mm socket is important of course, but the ratchet matters too. One with a swivel head will allow you to hook up to the socket and still clear the shroud. Done from under the car, you can put one hand on the TC and feel for the plug, and rotate the engine with the other. Draining the TC is very important, as is frequent changes. In a 722.0,.1,.2,.3,.4 I like to change at 20-25k. Call it overkill, but I’ve never had a transmission fail. And I use Febi 08971, which is outstanding in terms of transmission feeling and performance. Especially in the old fluid coupling boxes.

Re: [MBZ] Draining Torque Converter
Here's an idea. Turn on your smart phone video recorder, place it so it has a good view of the window where the drain should appear. Rotate the engine at the front while reading out loud the crank pointer readings. Review the recording, you'll have a good idea of where the drain is.

Re: [MBZ] Draining Torque Converter
The problem is that it is hard for one person to watch for the torque converter drain (at the back of the engine, underneath) while rotating the engine from the front. I think I used the method Dan described, using a flat screwdriver to rotate at the back of the engine, from underneath. Once I found the drain, I wrote down the reading of the crank pointer, so next time I can rotate from the front of the engine. 27mm socket on the crank pulley. Rather a pain to get in place. -- Max Dillon Charleston SC ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] draining torque converter
In my 84 300D, I could work a huge socket (22mm) onto the crankshaft and 27mm, IIRC. 22mm is the PS pump, usually a fine alternative for turning the engine over. turn it by hand. Now, there's a fan shroud in the way, at the minimum. Is there an easier way to turn the engine? See above! But working the wrench onto the crank nut is best because you can work it while lying under the car looking for the TC drain plug. Also, since I can't start the car right now, which way does the engine turn? Clockwise, when standing in front of it. (Hint: look at fan blades. They work _with_ the prevailing wind through the engine compartment.) -- Jim
Re: [MBZ] draining torque converter
Hello Sunil,
I use a large flat blade screw driver and turn the engine by wedgeing the
screwdriver in the hole next to the one the TC drain plug will appear and
work the engine around - making sure to turn the engine in its normal
direction od travel. Clockwise when viewed standing in front of the car and
looking toward the radiator IIRC.
Good luck - BTW, do me a favor - when you remove the TC plug, look so see if
it has a alum washer on the plug please.
There's some smaller openings you;ll see near a large opening on the bottom
of the torque converter housing - the plug will appear
in the larger opening. Use the smaller openings to wedge the screwdriver
in - and pry the TC around.

Re: [MBZ] draining torque converter
Thanks for all your help - spun the TC around via Larry's method and
drained it. rather, it's draining now. time to put everything back
together.
YES - there IS an aluminum washer on the plug.
