Need help with driveshaft/shifter interference

Hello all,

I just had my early model driveshaft rebuilt (shaft has the vibration dampener cup around the guibo) and to get it to balance the shop had to weld a counterweight weight onto the outside of the vibration dampener.

Just got the car back on the ground today, and the counterweight is contacting the selector rod, and pops the tranny out of gear when the driveshaft rotates.

Should I remove my selector rod and bend it so it clears the vibration dampener? Or should I take the dampener off, risking the driveshaft not being in balance due to the counterweight on the dampener not being present, but for sure have no clearance issues with the selector rod?

Any ideas?

I think an e36 shifter has a bent rod... maybe someone else can confirm that.
just find onw and install it! if you bend your it will "move" your shifter knob making shifting awkward.

I got a selector rod with the zf that came with my swap so I'll check that out. I guess if the selector rod is longer, then once I bend it it will hopefully be close to the same length.

They put the weight on the vibration dampner? Eww...mine is on the driveshaft.

There are 2 different selector rods for the E36, a longer bent rod, and a shorter straight rod. You would probably be best getting a hold of the bent rod, and bending it a little more to make it the same length as your straight. If you just use the bent rod without bending it more you will most likely will not be able to grab 2nd 4th and reverse.

Ya I was pissed when I got the shaft back, but not much I can do about it now. I don't really want to pull the exhaust and driveshaft back out at this point.

Is the straight e36 rod longer than the e30 rod? Cause the one on my zf isn't bent right now.

I don't know about the E30 rod, all I know is the straight E36 rod is shorter then the bent E36 rod. When I did my auto to manual swap it came with both, and the first transmission I had the bent would not fit. I just recently swapped the transmission and now the straight won't fit so I used the bent (one transmission was from a 325 one was from a 318 was the issue I believe, as they have different joints on the transmission).

Just make sure if you bend the rod yourself you don't bend it left or right or you won't be able to shift.

I've got a press so keeping it straight shouldn't be a problem. I guess worst case I can cut and weld a section into the center to extend the rod if I need to.

I would take the driveshalf back to where you got it done.

You should have gave them to balance the driveshalf without the vibration damper.

When I took them the driveshaft it didnt have the dampener on it, but he said he needed it to mount the trans end of the shaft in his balancer. I didnt think he was gonna put weights on the outside of the damn thing

It comes apart, the end of the drum is just press fit over the bolts. trust me I've been running fine without it for nearly 2 years.

At first it doesn't seem like it comes apart, but it does.

I know I can run without it, but since he balanced it with the weight on the outside of the dampener, the shaft is now out of balance without it. I'm getting a pretty nasty vibration at 70km/h so I'm gonna have to take the shaft out and have the shop rebalance it properly.

And it's so much easier to remove/install when the balancer isn't in the way.
