new slave, new master tranny 'chunks'

[ptegler]

pretty sure it's not air in the hydraulics....
My Q revolves around the ball bearing and tallow soaked seal and plates of the tranny input shaft in the back of the crank.

 

Am I assuming correctly if these dry out, it will 'drag' the trans input shaft?  ( ...causing my issue(s) )
EG: reverse always 'chunks', unless I hold the lever against second ever so slightly, then shift quickly to reverse.
Neutral (at a stop light) will almost always 'chunk' going into first.

I haven't driven long enough to think about double clutching and the like.... just trying to understand, where I stand. Tranny was supposedly rebuilt, and I've played with larger master cyls (more throw) none of which seems to have changed my issue, hence my trying to understand what is dragging..making the gear spin when trying to shift.   TIA for any ideas/theories/flames...    🙂

4 spd or 5 spd ?

Are you sure the shifter bracket (the frame that supports the shift lever/linkage that's fastened to the tranny) is firmly fastened to the tranny casting, and the linkage isn't worn or loose?  Difficulty shifting into reverse is a symptom of a loose shifter bracket.

Clutch master pushrod adjustment.

 

What gear oil?

Not enough backstory to formulate a theory.

That seems unlikely .

more likely, there is also adjustment at the pedal

I'm going with pushrod adjustment as well. You'll have to pull the carpet back and expose the pedal box. There is a factory spec.

4 speed...looking for a decent 5 (o/d) but not there yet.  🙂

You may have put the slave cyl eye on the wrong side of the pedal stem.

hmmm.... clearing some cob webs...might be zero'ing in on my issue..... I haven't pulled the engine/tranny interface apart (yet?)
but when mucking about...  I did manage to have the throw out bearing arm slip off the pin when playing with the new slave cyl from underneath.  I thought i had it back in right or I'd hear all kinds of ruckus right? It does shift fine normally, it's just when the engine is spinning and the tranny output is not, you run into speed differences trying to go into gear (hench the crunch).
Having the clutch too tight would not create drag, rather limit it as needed (clutch would slip)

?? stepping back...this is a hydraulic not mech clutch linkage... maybe I'm misunderstadning you comment

I'm sorry, not enough coffee yet, I confused the slave cyl with the master🤔.
