Tranny bellhousing snaped in half!

[67 B-body]

Well, I dropped the trans back down and it seemed like the converter back all the way. I think it even scrubes the pump bolts if you tip it a bit when spinning it. I'm getting some shorter head bolts for the pump from work tomorrow to put in. They stick out a bit more than stock, plus the thickness of the bellhousing itself...... I'm still not sure what's going on yet, but this weekend I'll have a day to work on any issues holding it up. I'm also wondering if 10" converters are to big for it to set back far enough. Maybe they figure you'll be using something smaller like a 9" or less? I think they get thinner when you get to 9" and smaller?......

Make a 1/4 plate spacer if You find it's binding when You pull the bolts up tight...

Boy,,, I keep thinking that the manufacture would say something if spacers are needed for the difference in design. Further more, I hope they would build it into the housing itself and not rely on the end user to figure it out.... I did notice last night when messing with it for a hour or so, that the flex plate seemed to be a little crooked.... I ordered a new one at 10pm, and it showed up at the office at 10am this morning!!! Once again, Summit Racing came through for me.... I always get stuff the next day without any special shipping methods.... :hello2:

Too many variances

There are so many variances & style of TQ converter mfgrs. that they would have to have a book for all of them... I think "maybe" they may assume you have a 1/8"-1/4" mid plate, if you are using a SFI rated bell housing, the 2 go kind of hand in hand, most people that don't have a cage or chassis installed, probably won't go to the expense of a SFI replacement bell housing.... Your right Summit Racing "Rocks" :headbang: , same thing here, if they have it at the Reno, Nevada Distribution center, I get it the very next day, in Sonora Ca., with no additional costs... It's hard to beet that deal...

 

[moparpoor]

Sorry to hear all the problems.I had no troubles with mine.Have you contacted them with the issues.

 

[67 B-body]

Well, I'm pretty sure the bellhousing is to shallow.... The starter nose sets back into the hole, and it has about 1/4 to 5/16" gap to the starter flange. This is about the same gap as between the bellhousing and the block when the converter gets tight against the crankshaft.... It's really pissing me off! I double checked the item description, and it says NOTHING about having to use a mid plate...... JW Ultra-Bell P# is 92457. Is this what you used moparpoor?

 

[moparpoor]

I just put the trans in earlier with no problems.I just checked the part # and it is 92457.I still haven't even picked up the tools yet.

 

[moparpoor]

Is the converter snout going into the flex plate or could that be hanging up.The new PTC converter I just put in was a little tight.Just A thought.I have used many different converters with this setup.The thing litterally fell together for me.Minus a little converter wiggle to get it tight.

 

[moparpoor]

Can you measure to the bottom of the starter hole to the edge of the flange.I will do this also so we can compair specs.

Jim,

I just measured a big block 727 and it's 5 5/8" from the pad on the pump at the top next to the vent to the face of the tranny. See if your's measures the same and it will tell you if you need spaceres.

 

[moparpoor]

I just measured mine.I measures 23/4 inches.to the bottom of the starter hole.

 

[67 B-body]

I'll get the measurements first thing tomorrow morning.... The wife will have me busy watching a movie with her "Husband duty"....
Thanks guys!

 

[67 B-body]

If this thing needs spacers to work correctly, I'll be pulling it back off the trans and selling it!!!!! Then I'll be over to Daves house "dsd1967" and buying a trans from him...

Thanks guys!

I have a great routine to get out of those.I throw hissy fit like I am really pissed.Then she doesn't want to even be near me.Works awsome everytime.If I really pour it on I even get lucky later that night.

It's too bad the new bell housing isn't working out. It would be a little piece of mind.

Regardless.....I got the tranny cabinet open.....you got your choice of at least three big block 727's. Any time....I'm around all next week.

Yep,,, never had such a hard time Dave....
I might just be over to take you up on the offer..... I'll let you know.
I'll be extra busy over the next few weeks working on a large project for Kimberly Clark "baby wipes" Robotic system. Then the first week of May I'll be in LA at another K-C facility performing an upgrade and programming... Then the end of May I'll be out in Washington at Ocean Spray adding a new end of arm tool to a robot I installed a year ago... They also have some new programming options they would like to have..... Busy Busy!!!!

Mine does too,,,, what ind of starter do you use????
I have a factory style starter, and the mounting flange doesn't set against the bellhousing when I get to the point that it doesn't go any further into the starter hole....:angry9:

Jim,

Dave,
I got the same, but I think the trouble comes from the the bellhousing inside mounting flange to pump, and it's fasteners keeping the converter from being able to slide back as far as a factory bellhousing. This bellhousing has a flange that uses the face of the trans pump as its mounting pad. The bolts then go through the flange into the pump bolt holes.

moparpoor:
What compensates for this thickness of the flange? It seems as if the face of the converter can scrub the head of the mounting flange bolts when I push it all the way back into the bellhousing..... Even at this point, I think it sticks out too far for the bellhousing to meet the block.
Are you using a 9" converter that is thinner from the flex plate mounting pads to the highest opposite side point?
Thanks for all the researching guys!!!:icon_eyes:

 

[67 B-body]

Mopar poor,,,,
When and if you get time again, and are willing, could you measure from the mounting surface back to the converter flex plate mounts with it setting all the way back?
Thanks in advance!

Bell diff

67-body,

I just took a look at your pic and moparpoor's pic...and see what i think your issue with the new bell.
Moparpoor's bell mounting bolts are countersunk and you's appear not to be, at least what i see in the pic looks to be the problem.

hope that may solve the mystery

Mike
