can anyone give me some diagrams with bolt size info, or point me towards where to get a bolt kit for connecting the bellhousing to the engine on my 1990 xj? (5 speed) thanks in advance

 

Ill check the bolt size on my spare engine tonight after work if no body gets you an answer before then

pieced together on my iPhone using all the extra parts from my cherokee...

 

i think the pesky bolt your refering to is an E12 http://www.greatnecksaw.com/product_...oducts_id=7320 star bolt and you need this special socket to get it out.... if i remember right..

 

Upper screws (the E12 ones) are threaded 3/8"-16UNC, the lower ones are 7/16"-14UNC. I don't recall the lengths, but you can match them up when you look for replacements. You need not go to the dealer for these (just get decent quality parts.)

The upper screws may be readily replaced with standard hex heads, socket heads, or even studs - I do it all the time. The Torx head was designed to ease automated assembly - it tends to be located better by the socket, and more torque may be applied to a Torx head than a standard hex or socket head (however, that's not a problem here - they're not exotic high-torque applications.)

(NB: You'd probably have gotten better answers posting in the right section. In this case, OEM Tech. I feel like I've answered this question myself before, in fact...)

 

Welcome to the forum!

 

just use a 3/8 socket for the top 2 bolts! the rest are pretty standard sizes.

 

Dealer gave me these specs: 7/16 and 3/8 too

 

Even odds you'll bugger up the heads - go to Sears, and get a set of E-Torx sockets there (you'll find a set made by Lisle tools that are quite good - they're on a red & white card, skin-packed.)

You'll find them handy.

Recall that Torx was developed by Camcar-Textron in order to facilitate automated manufacturing, not serviceability. My only real complaint with Torx is that the same set of head sizes serves both SAE and ISO - so you don't know what you're taking out until you measure it.
