Hi. I have been rebuilding my 34 trans for my fordor so it’s been start and stop over a couple a months over getting time and getting parts. Thought I was finishing it off today.
All seemed good, before I had the front bearing retainer tight just snug, put the shifter in tested the gear shifting , seem to work good, pulled shifter back out, tightened up front bearing retainer, then noticed it’s snug to turn by your hand now to snug grab a rag and twist pretty good by hand.
Slack it off a bit, not much, turns over nice feels like it should.
Bought all my parts pretty much from Mac at Vanpelt sales and a few nos pces. So pretty confident everything is correct there. So I must have done something or missed something.
Before I start to dismantle thought I would throw it out there and see what the most likely cause would be ? Something I missed or did on the main shaft assembly I am assuming .
Thanks in advance.
 
I don’t know maybe there is nothing wrong it’s just snug thought it would be a little looser to turn , maybe it’s the difference in gasket thickness I’m just not sure , just a little tighter than I am use to say with Muncie type four gear.
 
I just put it on feels about the same., Maybe it’s just me maybe there is nothing wrong , it’s not dumb tight it’s just a bit of a grip twist type turn just tighter than I would have thought . More like when you try and turn an automatic input shaft. …
I will try my pinion torque wrench and see what it reads
 
If I put my pinion torque wrench on the nut through the u joint it takes 25 inch pounds to turn it . About the preload of a diff. Is that slightly tight ?
 
All good advice above, pull the top cover, make sure the brass rings are not stuck, and oil things up
 
Yes everything is all oiled up and I did shift through the gears I will put the shifter back in it tomorrow and do it again and see how it acts, but yes used assemby grease in areas and poured some oil I rotating the gears before putting the top on.
Thanks everybody appreciate it
 
Yes that is neutral
I would have to agree it just seems a little to tight
I just loosen off bearing retainer on either end a bit and it makes a noticeable difference and turns more like I think it should.
 
Just to be sure - stock ‘34 transmission? Do you have the oil baffle on the main drive gear? The early synchro is not held by a snap ring and should slide back and forth easily about 1/8”. If it hangs up on the main shaft that can be a problem. We don’t put assembly grease on the brass surfaces as it makes them grab sometimes, but we do spray with a thin lubricant called “power lube”.
 
Hi yes stock 34 transmission, Yes I remember correctly yes on the oil baffle
On the grease, I use a lighter one made by driven that I use for engine bearings during assembly.
I put a new synchro in it and seems to me it was hanging up at first until it was moving freely. Would It be worth trying the shifter , turning trans by hand and going through the gears see if it frees it up ?
Thinking to try a few things like that before I tear things apart which I am hoping not to have to do. It does turn smooth just tight
Thx
 
I would remove the shift tower and make sure the synchro is moving freely - not hung up on the main drive gear or second gear cone. Put the slider in neutral and then see how it feels. Do you have gaskets at the front & rear retainers?
 
Ok I will do that thanks. Yes I have thin gaskets at each end , and it seems like if I doubled one gasket up it would about the right amount of clearance seems like it’s about that close to be correct in my mind.
 
I am using the original earlier one with out the seal I will see if I can figure out some pictures thx
