input shaft stickout lengths

[scotty]

well, i want to get started making some kind of spacer for the t150 bellhousing on my dodge 435 tranny.

im not sure how thick to make it.

basically,i guess i need to know where the end of the input shaft should be in relation the the edge of the bell,in amc applications. i have the dodge bell that came with the tranny,but im not sure if thats comparing "apples to apples" or "apples to oranges." tongue.gif

id hate to have to pull my t18 in order to take this measuremnt :eek: im currently running a v8 t18 behind my 258,so ill assume the input shaft goes into the pilot bushing the same amt for both engines.

anyone have any info? smile.gif

Scotty if i remember right when I put my ford 435 in the input shaft was 6.5 inches from the front of the tranny.I remember worrying about this because the T176 stuck out so much more (it was 7.5 inches I think).But when I got my new pilot bearing it was alot larger and went into the crank farther out than the 1 for the T176.hope this helps.

I don't know if this will help, but when I was shopping for an NV4500, Advanced adapters sold a spacer/adapter between a jeep t150 bellhousing and the Dodge NV4500 tranny. The shaft length on the Dodge NV4500 is 7.5". The spacer adapter was 1" thick. On the AA spacer they machined a hole in the center on one side that was the same diameter as the tranny bearing retainer, and on the other side there was a lip that slipped inside the center hole in the bellhousing.

Laj10,the dodge 435 is a bit different than the ford 435,so im sort of venturing ito uncharted territory, the input shaft is 8.5" long on the dodge 435.

so i am now alittle confused. if the t176 input shaft was 7.5",it seems odd that the dodge nv4500 would need a 1" spacer with the same bell and same input shaft stickout length.

hmmmm. :confused: maybe i will call AA and novak tomorrow and see what they have to say smile.gif

i have had some thots of swapping my dodge output shaft and adapter into a ford 435 to simplify things,but id kind of like the extra couple inches if i can get it to work. that way my shifter will be closer to where it is now than it will be with a 6.5" input shaft(ive become pretty accostomed to where it is with the v8 t18 behind the 6 cyl).also,tyhe dodge case is different,as only the 2 top holes line up. the bottom 2 are no where close.

once i figure out the spacer and the t/o bearig situation,ill stillhave to have a custom pilot made.

thanx for the input thus far. anyone eles have any thots? smile.gif

The hole for the bearing retainer and the
lip on the bell housing side that was mentioned
above is critical to have as this is what
centers the input shaft to the crank center.
If they are not lined up right the input bearing
on the trans will be short lived and just becouse
the bolts go in the holes does not mean the
trans is lined up correctly.

ummm,ok. smile.gif

i understand these things,but the information i require at this point is the input shaft length vs the bell length.

i can prolly just measure a t150 input shaft if no one has any ideas.
