Bell housing crack [Merged 2-9]

[ONR]

Can i just weld this back together...with the proper welding of course or should i just suck it up and buy myself a new bell house/tranny, its about i woudl say 6" long and then has anotehr lil part about 1" off that...and is there anywhere in northern/bay area cali that i can pick one up at?....Thanks

[candela]

If it were me, Id just weld it...

[Defiant]

My god, what have you been doing? Try All Foreign in Berkeley, or check around in the classifieds here and eBay.

[miguels3000]

No man just changed the bell housing, buy a core and switch over the insides. Youre going to spend the same.

[ONR]

thats what my dad wants to do is just weld it cuase its the bell housing and thats free oposed to buying a new tranny/bell housing...and i know my throw out bearing is shot...and my clutch is not grabbing/disengaging properly so i can work on that while thats all off...

[miguels3000]

If youre car is awd and you have alot of mods, I would change it, because the integrity is already broken. and with all that force that is going on in there i wouldnt want to risk anything else happening. but i guess you could weld it if you wanted to. And mainly its free.

[ONR]

the car is stock so i dont really have to worry about that yet...i plan on doing alot of stuff but for the time being i just wanted to be able to drive myself around town...and i will within a couple months when i start moding figured id buy a new tranny any ways just for fun...you konw just have it as a spare...ill have to check out that "all foreign" place out in berkely...

[RipperXX]

well i found out what that disturbing pop was when i was bolting it back on.. a wire clamp got inbetwine the motor and trans bell houseing.. it made a 2 1/2" crack down the side of it....

can this hurt anything???

[allwheelTSI]

it can snap off and your transmission can fall out!!









eh,i don't know what could happen..

[turbolover2]

Chances are that it would be ok. But, to be on the safe side, you might want to have it welded.

[RipperXX]

well after talking with my dad about it im going to get it welded when i get the engine rebuilt but it poped again which at that moment i was thinking GAWH DAMN IT!!!! but it actuly went back into place and you can't see the crack anymore...

[NVmyRST]

to make the long story short... blew up a motor, put on new head, and another block i had in my car... all ran fine for 3 days. Heres what happend:

on the 3rd day, the clutch started to feel like jello. So we thought it was the slave cyl, replaced it... still not working. but at the same time, there was this horrible squeeling noise, figured it was the throw out bearing. Went to replace that and realized the bell housing was cracked under the top hole on the intake side of the tranny, towards the exhaust side. Also the top hole on the exhaust side is completely broken off, on the bottom of the block on the exhaust side the ear is broken off.

Now when it was taken apart, there are not marks on the flywheel, pressure plate, disc or input shaft.

The one odd thing is that the line up pins that are in the block are now stuck in the tranny.


What would have caused this to happen? Any ideas are greatly GREATLY appreciated. Just a little background in case anyone needs to know, ACT 2100, RRE Lightened flywheel, and a new transmission. And i hope this makes sense... as to i am about to go insane....

[CleanGS97]

maybe it got "clutchwalk" .,.. honestly im as lost as you.

[Defiant]

Clutch housing bolts hadn't been torqued and worked loose.

Hey I have a 92 AWD 5-speed trans sitting around over here with a cracked bell housing (the part that bolts to the engine block) and with some huge chunks broken off it. I was wondering what year trans I could pull off another bell housing and bolt it up?? Any info would be nice. Thanks.

[Phil Sochor]

Does anyone know anything about this???

[boostedinaz]

You should be able to use one off any 1G trans as long as they are the same IE FWD AWD. The only difference that i can for sure say is the 90 have different levers and spline count.

Ok,

heres the problem

Recently the bolts connecting the bell housing to the block came loose..Making it hard to put into gear and it was grinding into the gears. I tigtened them up and all was fine..until yesterday, when I realized this was happening again. I looked uder the hood and car and all the bolt were tight. Then I realized that by the bolt that is closest to the bottom motor mount, the block was cracked right after the bolt and that the bell housing was shifting because of that everytime I pushed in the clutch. So a mechanic thinks that it can be welded, I need to know if this is possible. He is talking about welding the crack and then welding a plate to the motor mount w/ a 90 degree angle to the bolt and thread the bolt through the holein the plate and back into the block. This may be hard to understaand. I would like to know any input..

[krosTSI]

Allright, ever since i put in my ACT 2600 my gears would grind like crazy and never go into gear. I snooped around and realized that 2 bolts were extremely loose from my bell housing to my block I tightened them up and the problem was resolved. But it keeps on coming back. there always coming loose, bolts arent stripped or anything just like they unthread themselves. Im think there is alot of flex between the B.H. and block that is causing this. also my pedal feels real sloppy no pressure. any one have a clue?
Thanks,

[PogiTSI]

its possible that there streched. try getting some new bolts, and see if that helps. also are your torqueing those monsters???? ALSO are you sure you got all the bolts in on the bottom???????

Also, use some lock-tite on the threads.
Have you recently had the timing belt replaced? It sounds like you might be getting some vibration that may be causing your bolts loosening. I had a problem on a car I picked up and the rear balance shaft was 180 off and causing vibrations that the seller though was bad bearings. Its bolts were coming loose in the bellhousing from that.

[krosTSI]

I use lock tight every time and I torque them down to specifications and i just had my timing belt done 10,000 miles ago. Still dont know why, I'm gonna go out and do a lot of steps to it. Check the slave cylinder, master cylander, mess with the pedal assembly, adjust the something rod. hopefully i figure this out soon can drive it any where.lol
thanks alot guys,

[krosTSI]

hmmm

[95TalonTuner]

Well for future reference, you should get new bolts and use Locktite.

[krosTSI]

how many bolts go into the block from the bellhousing?

[91TalonTSiCT]

I think theres 3 into the block(2 up top and 1 in front) and 1 into the housing underneath by the tcase.

[krosTSI]

Allright all the bolts appear to be tight. But when i press ion the clutch the whole tranny andbell housing shifts towards the passenger side, but the block remains still I cant really determine where the stress is coming from?
Thanks guys,

[krosTSI]

Dude the exact same thing just happened to my block. have you fixed it yet and if so what exactly did you do. Didnt know if the welds would be strong enough to handle the torque of the 2600. please get back to me quickly.
Thanks,
-Ky

[wortdog]

This happened to me a couple of years ago. I never tried welding it, which could work, but it will never be as strong as it was stock. The gusset bracket your mechanic suggests is a pretty good idea, together with the weld it should be enough to hold. My 'solution' to the problem was to buy a different short block, rebuild it, and swap it in.

Before I fixed it, I got by for a while by drilling a hole through both sides of the front motor mount and running a bolt all the way from the trans to the far side of the motormount. That was probably the most ghetto fix ever.

I bet the little 12mm block to bellhousing bolt by the starter is also broken/missing.

The stress is coming from your foot on the clutch pedal I have found that it is very important that you get the rear lower bolt in. If it isnt in tight and not stripped it can make all the other bolts back out. Also driving around with loose tranny bolts can weaken the bellhousing and make micro cracks in the metal. an ACT2600 dont help matters
Hope that helps
