Split case : gear shift bushing ?

[paf]

Hello,

I have a euro 58 bug (I know this is for oval only, but split case is more common on oval than on 58-67 bugs, this is why I post here) with a split case transmission. I changed the fluid to a new one 75W90, but I still have the problem so shift down to 2nd when it is cold (grinding) and sometimes to engage first gear when stopped. That was present before, even if the new fluid helped for mild temperature conditions. Some tells me to change the shift bushing, and/or the coupler, but I would like to be sure that the bushing is present on a split case because I found contradictory information on that, for instance on the workshop manual in french for 52-57, not mentioning the bushing. Can someone help me to understand ? thanks.

Are you speaking of the shift rod bushing in the tunnel?
if so 58 didn't have one from the factory just a spring lever to hold tension on the shift rod.

Yes I was dealing with this... So no shift rod bushing... Then the problem is related to the coupler only ?

How does it shift with the engine off?
could be coupler, take off the cover and watch it as you shift. it is just a steel clad piece of rubber and could be soft. Also how is your fee play at the clutch pedal?

Free play is OK (20mm about 4/5"), I set it up recently, when I drain the old fluid : June this year. Can check again. I will check the coupler as well, maybe it is just loose.I do not remember how it is when the engine is not running, I will check as well this evening.

What condition is the nose cone bushing?

Check that the coupler bolts are tight and properly safety wired.

Do check the clutch pedal free play is correct.

Boden tube should only affect the release of the pedal. The proper curve in it acts as a shock absorber so the clutch does not bounce when suddenly released.

waoooo.... I don't know for most of them, but the clutch cable is new, I changed it last year due to a breakage... the bowden tube, is the same because I did not change it as it was correct (maybe I should have done it). The rest, well I do not know...

At least I will check the few item I can check.

Just by curiosity, changing the nose cone bushing needs the tranny to be out of the car ?

Hello,

I checked several thing yesterday evening :

* the coupler is ok, both screws are correctly tightened, safety wires are still present
* the freeplay was maybe to important, I tried to reduce it, but at one moment this is difficult to find the limit between moving freely and resistance is felt... I did not make a run yesterday, but will as soon as possible.
* the strange thing I noticed, is that when using the clutch pedal I can hear a squeak coming from the cable. I checked the Bowden tubes and while on all books the curvature is thru the floor on mine it is thru the top, I do not think this can be the problem, but I am doubtful about the squeaking... I did use lot of grease when i changed the cable however.

The thing I did not mention originally is that my bug is equipped with a SperrWolf shift lock from the factory, and while I wanted to check if the shift plate can be adjusted, I faced the issue that I am unable to understand how to dismantle/remove the shift lock. I will try to find documentation, but this is not similar to the service bulletin I saw on the site.

Next is to tests with the free play reduced.

Been a while since working on ours. Remove the screw in the front of the lock. Turn key to unlocked position and shifter in neutral. Slide top toward rear.

Hello,

I checked again the clutch freeplay setting, and found something strange : the pedal is really loose at the beginning of the movement, whatever is the position of the nut on the lever (tighten or not tighten). I am not able to have it firmly and directly seated by the cable. The issue can come from this, isn't it ? I can confirm that the lever spring is present and not broken.

Not sure, before it broke, I did not meet the problem, I should have done something wrong when replacing it.

so the problem started when you replaced the stretched clutch cable?
could be the TO bearing is not setting on the clutch arm right?
