installing transmission...less than 1 inch close - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

onehalfasia · 09-06-2007, 09:16 PM

working on the transmission install, so close but wont go, is it lined up if its that close or do i have to adjust the angle for the final inch. feels like when i try to install it(shaft part) goes up a small lip, then when removing 1mm or so out it slips down off the lip, thats from the 1mm of in/out play, any advice appreciated. transmission rotates freely and is supported by a few jacks.

jack on the bellhousing until the input shaft is lined up in the hole.

After that, grab the tail, and man-handle the hell out of it, shaking/wiggling until it works in.

I got mine as close and even as I could and then started putting the bolts in. Finger screw them in as far as they will go first and then start wrenching them down across from each other.

Wrench one down a little bit, then wrench the one directly opposite of it. Do that around the bellhousing and it will pull it into place. But make SURE it's as straight as you can get it and that you take your time wrenching them down. Wrench them down like in like 25% intervals.

Do what John Griff said first though, what he said is definitely preferred.

Sounds like your input shaft may not be lining up with the pilot bushing correctly... Id try lining the disk up again, and retry sliding the tranny in.

TB? You mean clutch?

WTF are you talking about.

bigOdom1 · 09-06-2007, 09:48 PM

clutch alignment tool properly used?

onehalfasia · 09-06-2007, 10:38 PM

left the clutch alone, had to reconnect/swap the clutch fork clip, i'll try the man-handling and maybe bolts tomorrow, so if its that close it basically just has to be pressed together? thanks for the help

johngriff · 09-06-2007, 10:39 PM

foot on the tail of the trans, wiggle and shove.

s13rookie · 09-06-2007, 10:42 PM

might be dumb, but are you sure the backing plate is not keeping any of the pins/dowels from entering through?

nissandr1ft · 09-06-2007, 10:53 PM

...I meant pilot bushing.

Sometimes having somebody tilt the engine towards the firewall help.

trsilvias13 · 09-07-2007, 12:41 AM

not sure if it just me, but looks like the top is closer to than the bottom, just need a lil more muscle and wiggle in if that is the case.

240tek · 09-07-2007, 12:47 AM

The trans is tough at this point, use your strength, while rotating trans keep it parallel with the shaft. Ive never heard of screwing it in tho. Good luck

holybushoffire · 09-07-2007, 01:06 AM

Just do like everyone else says and be a big burly mountain man about it.

If after so many tries you start to feel you're going nowhere, check the clutch and make sure it's the right one.

I believe it should have 27 splines.

also try a little emry cloth on the inside of the cutch disc. Sometimes the finish could be a little sloppy and just needs to be cleaned up.

Dream240 · 09-07-2007, 09:03 AM

You should never have to use the bolts to "pull" the tranny onto the engine. I can see 2 main problems with this. One, your forcing the input shaft into the pilot without it being properly lined up, this can damage the pilot bushing and cause it to wear prematurely (it's only brass). And two, you can also damage the threads in the block by pulling against the catching spot.

Anytime you have a problem with the re-mount of the tranny, you're clutch/input shaft/pilot bushing alignment is off. Most of the time this happens when you initially push the tranny on and don't have it lined up. You end up wiggling it too much and all it takes is the slightest mis-alignment and you'll never get it on.

All you have to do is pull it the tranny back off, recheck the alignment with the clutch align tool, if that's good then re-mount the tranny only DON'T STOP guiding it on. You should keep ALL the weight of the tranny off the input shaft while guiding it on. And use the tail end to help maneuver the tranny for that last portion. That last inch is the pilot bushing. Also jack up the front of the engine, you should get about 1-2 inches of lift. That will make the alignment much easier. You should get the tranny slid on first try with moderate effort.

Oh yeah I just noticed....WHERE'S YOUR BACKING PLATE?
