My buddy years back put a mercedes 5 cylinder diesel in his 4runner to get the bellhousing done he went to Lakewood Bellhousing, it was awesome just bolted right up, according to my friend. Maybe they could help out? Just a thought. Heres the link.

Not at all.

 

This is great stuff here. To clear my freshly foggy head, Bill is working on a bell to make the 9" fly/clutch work with the T56, which is the alternative to Chad's adapter plate and the custom 11" Fidanza fly that works with the LT1 trans in particular? Chad's also allows for tons of clutch options while Bill's allows for other GM trannies other than just the LT1?

 

or is Bill making the housing for the 4g6x motor? ~ I'm trying to make sense of this and several other archived threads. :rolleye0018:

 

...with both routes intended to beat out the oh-so-painful, slow, & expensive customization otherwise.

 

...I use the term "work with" loosely to mean bolt-on without custom making many other components, using available shelved parts like Bill says.

the original plan was to use the LM-1 T56 on a narrow block 4G63, the only thing I have built for the wide block ( 4G64) is the GM auto trans adaptor

 

I had no intention of making anything for the wide block, I was just going to make a couple of narrow block /Toyota conversions, but then I was asked to do the LM1 then that lead to the wide block and this time use the LT 1 T56 and then that got into a discussion about flywheels and combinations and internal throw out bearings all that stuff

 

The bottom line is this, when I build a bellhousing, I use the clutch controls from the given donor trans or engine depending on what works, I use over the counter parts that are easy to obtain and not a lot of money.

 

Then I ALWAYS use the OEM flywheel, I know a lot of discussion has gone into lightened flywheels and bigger clutches but I keep the engine in original form and the trans in original form and combine the two at the pressure plate and disc, that way I have the original design from both sides without taking anything out of balance .

 

A new custom disc is a little over a $120.00 bucks , the throw out bearing, clutch fork , pivot ball and the slave cylinder will be all OEM Starion parts

Just to clarify, this is built to adopt the T 56 Lm1 six speed to the 4G63 narrow block

I added new gussets in the interior of the bellhousing, they are lighter with better alignment then the original

http://www.billsautofab.com/images/T56build.jpg

I moved all the bolt patterns out by 2% to allow for shrinkage in the casting process

http://www.billsautofab.com/images/T56builda.jpg

I added tubing as guides to build ribs on the outside of the housing to build strength and allow some cooling

http://www.billsautofab.com/images/T56buildc.jpg

at first I thought I would just use an internal throw out bearing but because of the cost I mounted the first gen Mits 4G63 narrow block controls so anyone could get cheaper parts

http://www.billsautofab.com/images/T56buildg.jpg

I just keep trying to lighten this little guy up without sacrificing strength, it was quite a task on the lower trans mounting bolts

http://www.billsautofab.com/images/T56builde.jpg

I will be using the AWD flywheel with a disc built by Dan @ competion clutch, the pressure plate will be the original Mits application

I finished out this t 56 ( LM-1) 6speed trans for the narrow block 4G63, I will be building the wide block T 56 next, but I have a couple other guys waiting for the EVO R 154 set up

http://www.billsautofab.com/images/T56bellhousing062.jpg

http://www.billsautofab.com/images/T56bellhousing066.jpg

This is built to accept eithr the FWD flywheel or the the AWD flywheel depending on the cut ordered

these housings are for the T 56 narrow block 4G63, they have to be proven and machined yet but they look right

http://www.billsautofab.com/images/T56bellhousing085.jpg

these are allheat treated to a T 6 hardness

http://www.billsautofab.com/images/T56bellhousing086.jpg

They will be using an AWD flywheel

http://www.billsautofab.com/images/T56bellhousing087.jpg

they weigh less then 18lbs >;o)

http://www.billsautofab.com/images/T56bellhousing088.jpg

they willuse the first gen clutch fork, pivot ball with a toyota throw out bearing

http://www.billsautofab.com/images/T56bellhousing089.jpg

these are T 56 on the left, R 154's in the center and W 55's on the right, they are all for the narrow block 4g63

http://www.billsautofab.com/images/4-18-2009.jpg

 

I didnt want you guys to think I was relaxin'>;o)

the fit and finish is perfect, very little has to be done to the pattern, what does have to be adjusted only pertains to making it easier for machining process

 

http://www.billsautofab.com/images/T56bellhousing0102.jpg

i am very pleased with the bolt spacing for the bolt patterns, not too big,not too small

http://www.billsautofab.com/images/T56bellhousing0100.jpg

It is centered perfectly

http://www.billsautofab.com/images/T56bellhousing090.jpg

I saved about twenty pounds of aluminun with my lower transmission bolt pattern design

http://www.billsautofab.com/images/T56bellhousing093.jpg

My original thoughts were to use the internal throw out bearing option, but after much thought I decided to include the original first gen clutch fork arraingement to keep the cost down

http://www.billsautofab.com/images/T56bellhousing098.jpg

all the time spent on thinning down the internal sides of the bell housing walls paid off well , it created such an unusual shape because of how the drafting had to be planned out for the casting process , but it saved a lot of wieght and kept its strength

I think what I will do is change where the pilot bearing rides in the crankshaft or flywheel to compensate for long or short shafts between the Lt-1 T 56 and the LM 1 T 56 transmissions

the T 56 is done and its just drop dead gougous >;o) reminds me of the time I was on the russian border on a midnight train ride when I was checked in at the Polish border by a drop dead gourgous russian customs officer >;o) ( true story)

http://www.billsautofab.com/images/T56bellhousing0067.jpg

http://www.billsautofab.com/images/T56bellhousing0068.jpg

http://www.billsautofab.com/images/T56bellhousing0069.jpg

the input shaft depth spacing came in real nice

http://www.billsautofab.com/images/T56bellhousing0070.jpg

this is the original 4G63 first gen clutch fork and pivot ball,the fitting is very nice, I am placing the slave cylinder on the passenger side again to avoid the exhaust heat

http://www.billsautofab.com/images/T56bellhousing0071.jpg

I had to decide how to construct the throw out bearing, it was a toss up between the thicker collar or a custom throw out bearing holder, I went with the collar because it added strength

http://www.billsautofab.com/images/T56bellhousing0072.jpg

I did this in aluminum but the real deal will be done in steel

http://www.billsautofab.com/images/T56bellhousing0073.jpg

http://www.billsautofab.com/images/T56bellhousing0074.jpg

 

http://www.billsautofab.com/images/T56bellhousing0075.jpg

I re used the stock Toyota throw out bearing from the W 55 series trans cheap and common parts

http://www.billsautofab.com/images/T56bellhousing0076.jpg

the pilot bearing was placed in the flywheel on this trans because its the short shaft ( 5 1/8 in) I will place the pilot bearing into the crankshaft on the longer shaft versions, that way I can use one bellhousing for both transmissions

http://www.billsautofab.com/images/T56bellhousing0077.jpg

http://www.billsautofab.com/images/T56bellhousing0078.jpg

BADDUDE fixed me up on the disc, ( he is great to work with ) this set up uses the original AWD flywheel and starter, the cusom disc, and the original Mits clutch pressure plate

http://www.billsautofab.com/images/T56bellhousing0079.jpg

http://www.billsautofab.com/images/T56bellhousing0080.jpg

I have to fit the slave cylider yet, I need to adjust the throw of the clutch fork just a bit but it will be fine

http://www.billsautofab.com/images/T56bellhousing0081.jpg

this is the total assembled package with the clutch all installed

http://www.billsautofab.com/images/T56bellhousing0082.jpg

the starter is the stock Mits unit in the exact same place as the FWD unit, the threads must be drilled out of the starter and the bolts must be started from the engine side back into the bellhousing

http://www.billsautofab.com/images/T56bellhousing0083.jpg

there is plenty of room for any intake manifold unit to be installed

http://www.billsautofab.com/images/T56bellhousing0084.jpg

I will be building two seperater plates,one at the engine /bellhousing location and one at the bellhousing/transmission location

I was sent a LT throw out bearing cover to work with

http://www.billsautofab.com/images/T56bellhousing0116.jpg

the input shaft is almost 2 inches longe in the LT version T 56 soooooooooo somebody had to take one for the team

 

http://www.billsautofab.com/images/T56bellhousing0117.jpg

 

http://www.billsautofab.com/images/T56bellhousing0118.jpg

http://www.billsautofab.com/images/T56bellhousing0119.jpg

this is the LM model that I had built with a 5 1/8th inch input shaft

http://www.billsautofab.com/images/T56bellhousing0120.jpg

I will be building an adjustable trans facing to allow me to build each bellhousing to suit the given input shaft

 

http://www.billsautofab.com/images/T56bellhousing0121.jpg

this first bellhousing will be built as a one of a kind , then I will be adjusting the pattern to accept the longer version
