found out a few things last night

[sw]

well a good friend of mine with a diesel td27t terrano stuffed his manual trans about a week ago, so we dragged it to my garage last night and dropped the manny box.

 

we had a plan, on my pathy i had done a engine and trans swap a long time ago and i had kept my manual gearbox, the box is in good condition so we thought how about putting my good box in his car. now my pathy used to have a Z24 4 cyl petrol engine so more than likely the box's are going to be different. we put them side by side, we looked at the numbers stamped on the boxs - td71c & z71c- DOH!

 

all along we had hoped we would be able to just swap the bell housing on the boxes and wa-la. we noticed that the trannys outer cases are made up of only 2 pieces. so no EASY bell housing swap. so we looked further and found that the numbers stamped on the boxs we had seen earlier were on the front section - the bit that bolts to the motor. so we looked at the back section of the boxes for another number & we found one - X1A#1. we checked both boxs and they both had that same number. GREAT!!.

 

so we pulled the boxs apart to swap the bell housing/outer casing piece. all we had to do was remove the bolts on the tranny, remove the front seal plate & remove one large c clip and then with much, much effort the boxs came apart. the housings were a direct swap. & once re-assembled the z24 gear box with td27t belhousing and t-case all went back in.

 

i know there will be different ratio issues but according to a local very cluey nissan nut it wont be a big difference

 

so there you go gear box mix n match. not bad considering local wreckers want $1200 australian for a second hand box.

 

i assume this would be valid for the v6 manny boxs as well.

Interesting, please update us on how it runs, considering hte ratio differences. Hopefully it does stay within the engines power band

AHHHHHHHHH

 

another night & no love

 

 

 

something not right with the thrust bearing fork................

 

i accidently put the z24 front seal plate on the the td27 bell housing. i think the ball that the fork snaps on to is in a different position.

 

= no drive clutch out and gear selected or crunching gears with clutch in trying to grab a gear.

 

we unbolted the slave cyl & grabbed a gear with the motor off & started her, got drive. something dodgy with the fork/throw out bearing

 

its all gotta come out AGAIN......

i accidently put the z24 front seal plate on the the td27 bell housing.

that turned out to be the exact problem. however its not the location of the ball the fork snaps on to, its the height of it and its also the length of the machined shaft on the plate, were the trans input shaft pops out of.

 

swapped em over and she's sweet as now!

 

 

still a little early to say about ratios, but we both drove it and it did really feel any different

 

so all in all this is a do-able thing to save some big $$$$$

quick update

awhile has gone by now and weve even got in a 4wding trip. as far as ratios are concerned we cant notice any difference. so alround

Nice, glad it worked out and that is good bit of info
