Unable to hit reverse gear with engine started

[Allanagtig]

Hey again Guys!

So, after ive been doing alot of work on the car, I wanted to take it for a ride. Since I bought it, I have had problems getting it in reverse. I thought I cured it by taking the gearbox down and calibrate the gearshift, but that doesnt seem to help it. It makes a soft grinding noise when I try to drop it in. The funny thing is, that sometimes it can go into reverse with the engine going, but most of the time it wont before I turn off the engine. I must add that the ball joint on the leversystem was somewhat worn and could do some back and forth motion in the joint, so id figured it might be there the problem is, but then again, why only when the engine is running? Also add that I have changed the slavecylinder and bled it afterwards.

Any suggestions on how to calibrate the gearshift as originaly intended? Or could there be some hidden factors that I might not know of?

Best regards

Must be clutch related. If it goes in easy with the engine off then the clutch isn't fully disengaged so it grinds and won't select.

I had the same thought, but nothing happent after the new slavecylinder was attached, plus I also did the bleeding process. I might have to redo it

If it would be clutch related, shouldn't there be issues with all gears, not just reverse?

The other gears arnt straight cut and have a better syncro setup. Do you really need to press the clutch to the floor to get the other gears? Where is the bite point?

I can update you alittle later on it as im on my way out to see if I can fix the problem by re-bleeding the clutch + minor adjustment. What would be nice is to have another mechanic standing under the car while I try to press it in gear and see how much the mechanism move compared to switching directly on the gearbox or with the engine turned off.
Also I tried to roll a bit back and forth to see if it helped, or take it in 1st or 2nd gear first, but without luck.

Ill let you know where the bite point is as soon as I get back home

Try reverse bleeding the clutch by injecting fluid into the nipple. Works for me.

How does that work step by step?

[diesel des]

I fill a syringe with fluid and put a hose on the end of it. Push it so all air is ejected. Then fit hose to clutch slave nipple and open nipple. Force fluid into system with syringe. Close nipple. Fluid tank can overflow so be carefull of that.

I also think this's clutch dragging issue related.
I been lived with this issue for 5 years before getting
The pressure bleeder and bled it with 4-5L
Of brake fluid.i have zero airlock in the clutch
Hose and started to think what the hell is
going on with me for past 5 years lol.you're still be able
to shift forward gear but not buttery smooth
Since synchromesh helping you there but
Reverse is straight cut gear without synchromesh.
It 's going to grind like crazy if your clutch is dragging.
Sometime i needed to switch the engind off
Before shifting reverse.that's ridiculous.
The easy way to tell if the clutch is completely
Disengaged,trying to shift into the reverse.yeah it
Defo stuck in there.pull the shifter boot and
Listening there whilst you're trying to shift her
Into the reverse.you'll be hearing some grind
Noise and kinda gear is spinning.

Edit# damn i hate my mobile screen that too small
For my thumbs typo lol

Just to update the thread. Came back to the car yesterday to rebleed the system. When i got into the car to drive it onto the lift there was no problems getting it in reverse �� grrr. So i drove back and forth trying to provoce it again, but no grinding noise, only smooth shifts. Wierd. No matter what, i decided to rebleed to see if any air was stuck in the system, but there was no air.
Been driving for some time now and it seem to have gone right so far. I just know that its haunted and soon it will do it again ☺
F...... wierd that on a few days it repaired it self. Cars Zzzzz ☺

Maybe the air found its own way out?
