id_gwagen Date registered: Dec 1899 Location: Vehicle(s): | Extending gearbox breather - how Folks, The auto gearbox breather (722.3) which I'm installing on my G looks like this (see pic), the gearbox comes from a sedan. Is this the way it is on the gearbox which come with the G? I'm sure it's not waterproof. Has anyone extend the breather using a hose or any other means. If so it would be nice to see pics of what has been done before. Any help / clues would be appreciated. (breather.jpg) Attachments ---------------- breather.jpg (55KB - 0 downloads) | ||

If so see if there is a nipple of some kind underneath it to attach the black plastic breather line that leads to the cluster in the drivers side shock tower. If/when you pulled out the old transmission out was there not an existing plastic line that you had to disconnect? Mark | ||

id_gwagen Date registered: Dec 1899 Location: Vehicle(s): | RE: Extending gearbox breather - how Unfortunately I didn't get a chance to see the old manual gearbox when it was pulled out, and it was sold not too long after, in fact what's left of the M110 is just the short block :-D I'll have to see whether there's a line going to the front. The cap itself has some play, by looking at another 722.3 being taken apart, it looked like it has a nipple / valve inside. I'm not sure it will shut closed when it's submerged, but I'd like to be on the safe side. I'll check again when I visit the garage tomorrow. Thanks guys. | ||

The mushroom cap should as roughneck suggested be OK for short periods submergered. The mushroom acts as an air bubble which will in most instances keep water/dirt out. However to fully ensure that no water enters in follow all the lines from the shock tower and you will probably find a stray tube that needs a home. If it is not long enough add a piece of rubber tube to make up the difference. Once again unless you are playing submarine on a regular basis it is probably not necessary. Mark | ||

id_gwagen Date registered: Dec 1899 Location: Vehicle(s): | RE: Extending gearbox breather - how Well, I went to the garage today, the mushroom cap is just a plastic cap with 2 small holes on the side. One snap with a screw driver it came off fairly easily. The diameter is 1.5cm (~0.6inch), so I'll plug in a copper/metal tube, put waterproof glue on it, then run a rubber hose to the shock tower. But the original breather lines are so small, I'll probably use slightly bigger hose so the tranny can breathe easier :-) I'm not trying to play submarine, but there are times (every 5 years) when flooding gets heavy that we have to ford 60-70cm deep water .... on the highway :-)) My wife blasted through a 70cm deep road for about 500m, the road was officially closed, only people with rafts were allowed :-) I guess my wife has more guts than me (or more ignorant) :-)) (bline.jpg) (bcap.jpg) (bcap2.jpg) Attachments ---------------- bline.jpg (88KB - 0 downloads) bcap.jpg (43KB - 0 downloads) bcap2.jpg (51KB - 0 downloads) | ||

Starter sists on opposite side Hi Harald, I know it's you :-) No the M110 is the engine that is being swapped to 617A, and it is being parted out, the only thing left is the short block, I'm selling the internals only if anyone interested (not sure about shipping yet), everything in the picture except the block itself (I need the engine number on the block for registration renewal). It's got the high-comp pistons. My 722.315 is actually a one piece gearbox whose starter is on the driver side (RHD), it exactly the same 722.3XX as used on 300Es (and some others) except for the location of the starter (see pic), the internal parts are also interchangeable. AFAIK these gearboxes were used in later W123s (>84) and W126 using M110, 617A, and engines in that generation. Down here, we call these older engines either the Grave engine, due to the fact they look like a grave (M102, OM617a, etc), or we call them also the straight engines, and the newer we call the slanted engines, I think you'll figure out why :-D Nice clean block, don't you think? :-D Edited by id_gwagen 4/16/2007 8:14 AM (722.jpg) (blk1.jpg) (blk2.jpg) Attachments ---------------- 722.jpg (64KB - 0 downloads) blk1.jpg (62KB - 0 downloads) blk2.jpg (72KB - 1 downloads) | ||

But how's that going to affect the 'health' of the gearbox since the link between the TC and the gearbox is supposedly water tight? how's that differ with the G-version of 722s or other auto trannies? I think the easy / temporary solution is to fab a deflector so that water is deflected below the hole. as long as the vehicle is moving I reckon it should be ok, any thoughts? | ||
