170DS Shift Rods

Title: 170ds shifter rods
Post by: richard on May 12, 2008, 07:07:03 PM
Hi Guys,  I have a problem that someone can possibly help me with.  During the assembly of my 170DS, I discovered that I had no shifting rods. These are the rods that go from the transmission levers  to the shift linkage on the steering column. I ordered a pair form the factory but can not make them fit as I think they should. They seem too long.  I am afraid I may have the wrong rods. 
Could I send my set to someone who could compare them with theirs and advise.  thanks,  Richard

Richard, where are you located?  I am traveling and away from my DS but could attend to this mid June.   I redid my column shifting, bushings, etc. last summer and i recall the rods are sort of tricky....they have to be positioned correctly on the shifting body claw and connections....you may have the right ones but they not be in the correct postion on each lever...   If you get no answers or takers here in the meantime....check back with me in about 1 month.

Hi Jim.  Thanks for your offer to look at my shifter rods. If I can not solve the problem, I will send them later.

You asked how the wiring was going.  We are continuing to work with the wiring but still have some unanswered details. For example, we are currently  running wires up the door post to the trafficator  locations.
Accordiig to the wiring diagrams, a wire goes from fuse 5 to the dashboard indicator light and up the doorpost column to the trafficators. Inside the trafficators, both bulb and the solenoid coil have one end grounded.
Therefore, it looks like there is always power to  either the bulbs or the  coils.  I do not think that makes sense, but I would like to have your thoughts.

Richard:  I came across this image I took of my shift rods, after replacing the nylon bushings and having the tranny cover open (during last years operation of redoing the entire shifting mechanism, claw body, etc...
maybe it will help for you to determine if your rods are too long.   I am back to my storage now and can measure them from the engine side (as it is somewhat more difficult for me to pull up the carpeting, and remove the tranny tunnel for this operation.   If an operation causes me to remove the tunnel this summer, then I can get to it from there.

Thank you very much for the photo of your transmission  showing  the shifting rods and the levers.  Mine looks exactly the same. I assume your  transmission was in neutral.  It is the other end of the rod coming from the top of the transmission that I think is wrong, ( too long).. See attached photo 

For  best results, it seems to me that this rod should be at approx, 90 degrees to the steering column lever.
On mine, the rod is close to being in line with the lever. Therefore the lever is bearly able to push or pull on the  shifter.rod.   I think this must be wrong, or maybe I am  thinking wrong.  Can I have your thoughts on this,   Thank you,      Richard

I know these are a pain to get right - I had the same problem on my 300, and they are pretty much identical. Looking at Jim's gearbox photo, and if yours is the same, it looks as though you have quite a bit of adjustment on the spline, so if you move it back, you may be able to get a better angle at the steering column.

Richard:   if I remember correctly there is a situation where the rod will not move at all (or just barely an inch)....it has something to do with the post (with the connection on the top lever (tranny) )which I believe is the one you are having problems with.   If that post assembly drops too far down, it will lock internally.  There is a circlip that holds it up into correct postion.  is it possible yours is missing...you can probably test it by pulling up on that post (take a 14mm wrench and un-loosen the tightening bolt on the claw body part in the engine....so it will move but not actually change gears, etc....

I discovered this when mine locked and I removed the tranny top and looked at the shifting post and noticed, when it drops, it hangs up....I believe it is a circlip that holds it up into postion.   I also resealed the tranny after re-installing the top (or it will leak).

Richard:  getting back to you on the rods.  I had occassion to remove my tranny cover today and remove my rods. 

there are 2 sizes:  I measured in inches:  one is 14+1/4 inch and one is 13+1/4 inch.   [/size] The shorter rod goes to the top of the tranny whereas the 1 inch longer one goes to the side for the main gears.   Today I was trying to get my shifting to work a bit smoother (I've already replaced all the bushings)...and I noticed that my  rods appear to be home-made with welded ends.  They probably made exact dimensions, but I'm not sure the angles are correct.   Did you ever figure yours out?

Richard:   I got some images from Scott Montoney tonight showing the profile of the shift rods at the claw body.   I had him confirm the way they come into the levers, since the workshop manual, I believe page 376 (PDF link below), shows them coming in from the driver side.   According to all my attempts to configure the rods differently, on mine, and scotts, they can only come from the engine side as shown in these images.

Do we have a DIY on this? I am going to have to do my ponton and it uses the same engine=trans as the 170D/Da/Db
Thanks,  Darryl
