Guys, this thread is way ancient news...there are quite a bunch of 4.0L powered amc's out there now.
Look at the section above in the six area. And YEA, it is much better than just talking about it! B.T.D.T. (did not get a t-shirt) I've lost track of the exact date mine hit the road, but it's been quite a while now. |

Some of this will be useful for my project - a 94 Grand engine going into a 82 Eagle.

I am doing this swap in a 82 spirit with a 95 jeep grand cherokee 4.0. I am running a 89 mustang t-5 with the stock amc t-5 bellhousing. I drilled a hole in the bellhousing for the cps and then made a plate with two spacers. The spacers move the plate out over the notches in the flywheel (a stock 95 jeep part) and the sensor mounts to the plate. The spacers happen to be the same thickness as the specal intake/exaust washers on 4.0 and 258 six cylinders. The plate and spacers then mount using two bellhousing bolts using longer bolts. Be aware that you must use a 4.0 starter with the 4.0 flywheel or flexplate, and the old big ford starter with the 258 etc flywheel or flexplate. The ring gears are in different places, it bolts up but won't ingage.

Well, the only thing about "rolling your own" (using any method) is that the notches have to be precisely placed, and a precise width.
The 4.0L flywheels have notches, the flex plates have a ring welded perpendicular to the plate with square holes where the notches would be. You can use a 4.0L flywheel or flexplate with an earlier six (as early as 72) with no problem -- bolts right on. The stick is easy, just use the 4.0L pressure plate and get a clutch disc the right diameter to fit the trans shaft. Not hard at all, though might take a little research. The older model clutch may fit also. I don't recall what disc I used for the T-96, think it was a standard 4.0L clutch disc... may have been for an earlier Jeep. If necessary I still have the paperwork in a folder and could look it up. For an auto you have to be careful that the torque converter isn't pushed back in the trans pump too far. When using an AW-4 flex plate with a 904/998 converter you have to shift the converter forward about 3/8". There are some nuts on the flexplate or converter that can be removed. I haven't done it, someone else relayed that info (after destroying the first pump -- changed pump, made the mod, and carried on in an Eagle). Or you can get a TJ flexplate and be done with it. They used a 999 which has the same style TC and flexplate as teh 904/998, but has the ring on the flexplate. For $75-$100 that's the way to go for an auto (http://cgi.ebay.com/ebaymotors/Jeep-Wrangler-TJ-Flywheel-4-0L-Automatic-Trans-97-02_W0QQcmdZViewItemQQ_trksidZp1742Q2em153Q2el1262QQcategoryZ33732QQihZ008QQitemZ180317718104). Measure for sensor clock position as I've already explained in earlier posts. Note that the 87-90 Renix flywheel/flexplate is notched differently than the 91+ H.O. system parts. Renix has notches all around evenly spaced. The sensor doubles as an engine speed sensor as well as crankshaft position. Edited by farna - Jan/16/2009 at 6:37am |
