mariobedayo Posted September 24, 2016 Share Posted September 24, 2016 HI! Moses, Im here again to ask you about my problem with my ax 15 swap, we change the transmission 42 RE to ax 15 , now we have this problem me and the mechanic cannot solve this problem , when he push the clutch pedal engine at idle trans will not engage to 1st gear . we shut off the engine engage 1st gear car on jack it engages wheel turning clutch pedal is depress wheel continue turning shift to neutral it will not disengage very hard., as if the clutch press is not moving. i read to some forums on the jeep who converted 42RE to ax 15 they advice to machine the ax 15 output shaft about 3/4 of an inch. im using the internal release bearing as i dont have the external type that needs to change the bell housing. what will i do first is to use this internal release bearing for the car to run and later if i have money ill buy the external with a bellhousing for this external slave cylinder., what will be your advice about this trouble that we are encountering please Help us.do i need to cut out 3/4 in the output shaft. Thank you. Mario Bedayo Quote Link to comment Share on other sites More sharing options...
Administrators Moses Ludel Posted September 24, 2016 Administrators Share Posted September 24, 2016 Mario...If the transfer case fits up to the AX15 transmission without the AX15's output shaft bottoming in the transfer case input gear, that is not the problem. Measure the stick-out length of the AX15 output shaft and compare this with the depth of the transfer case's input gear splines. It sounds like either: 1) the clutch release bearing is not moving the clutch cover fingers far enough or 2) the AX15 transmission input gear/pilot nose is sticking or binding in the crankshaft pilot bearing. If the release bearing is not moving far enough, check the clutch pedal rod clearance at the clutch master cylinder piston and bleed the hydraulic clutch release bearing. Make sure the pedal pushes enough fluid into the release bearing to move the cover fingers far enough. Moses Quote Link to comment Share on other sites More sharing options...

Administrators Moses Ludel Posted September 28, 2016 Administrators Share Posted September 28, 2016 Mario...The nylon straps hold the release bearing together during installation. Once the hydraulic release bearing is installed against the transmission, you unstrap the nylon straps. Here is a link to AutoZone's steps on installing a Jeep YJ hydraulic clutch release bearing: http://www.autozone.com/repairguides/Jeep-Wrangler-YJ-1987-1995-Repair-Guide/CLUTCH/Hydraulic-Concentric-Bearing-Slave-Cylinder/_/P-0900c1528008ae3f This is the parts installation sequence. Follow the steps. Steps 8-13 cover the hydraulic bearing installation. Moses Quote Link to comment Share on other sites More sharing options...

Administrators Moses Ludel Posted October 8, 2016 Administrators Share Posted October 8, 2016 Mario...If the hydraulic release bearing is new and not leaking (seals good), the only other need is enough fluid volume from the master cylinder. Make sure that when you release the clutch pedal, the clutch master cylinder pushrod retracts all the way. There should be a slight amount of play between the clutch master cylinder pushrod tip and the clutch master cylinder piston. If there is not enough play, see if you can adjust the clutch pedal height to allow for full movement of the pushrod. When the pedal depresses to the floor, there must be enough master cylinder piston movement to provide the fluid volume needed at the release bearing. The piston travel must push the right amount of fluid into the hydraulic release bearing. Be certain that the clutch master cylinder is not leaking internally. If the clutch master cylinder seal does not trap the fluid, the fluid will bypass within the clutch master cylinder and leak past the internal seal. If this happens, too little fluid will be available at the hydraulic release bearing when you depress the pedal. Another possibility is that the clutch cover's release fingers are too low or misaligned. This can be caused by clutch installation issues like the clutch disk being installed backward. Make sure the clutch disk hub/center is facing the right way. Compare this with parts diagrams or online illustrations and photos.

Again Thank you for your time. Sorry that i bothered you a Lot. Mario Bedayo Philippines. Quote Link to comment Share on other sites More sharing options...
Administrators Moses Ludel Posted October 9, 2016 Administrators Share Posted October 9, 2016 1994-up parts will work, Mario. The AX15 transmission does require a front bearing retainer change to accept the mechanical release bearing. You also need the release arm and pivot, the external slave type bellhousing and an external slave cylinder, plus the hose/tube that carries fluid from the clutch master cylinder to the external slave cylinder. Make sure your clutch master cylinder will work with the external slave cylinder and fluid tube. The tube comes with the external slave cylinder. Here is an example of the complete hydraulic system for a YJ or TJ Wrangler, sold as a unit: https://www.summitracing.com/parts/dhb-cc649002?seid=srese1&cm_mmc=pla-google-_-shopping-_-srese1-_-dorman&gclid=Cj0KEQjw1ee_BRD3hK6x993YzeoBEiQA5RH_BOL2pOWP-0cautZ3yXydyuL0tc646Grj1vPTc6Ypi1UaAlJ38P8HAQ. This may not fit your ZJ. It's just an example of the parts. This application fits at the left side of the bellhousing. Not sure which bellhousing you plan to use.

Administrators Moses Ludel Posted October 11, 2016 Administrators Share Posted October 11, 2016 Mario...This 2.5L AX5 bellhousing will not work with your 4.0L/AX15. They are different engine block bolt patterns. Also, the AX5 has a different bolt pattern than the AX15. Moses Quote Link to comment Share on other sites More sharing options...
mariobedayo Posted October 11, 2016 Author Share Posted October 11, 2016 Hi! Moses , Thanks for the advice im looking for AX15 bell housing so that it will fit my requirement . Much thanks, Mario Bedayo Quote Link to comment Share on other sites More sharing options...
mariobedayo Posted October 20, 2016 Author Share Posted October 20, 2016 Hi! Moses , This is just to fllow up or to let you know that the ax15 transmission that i swap has the transfer case attach. we did not remove the transfer case np 231. so i think theres no issue about this.. what do you think? we just have the front drive shaft lenghten. so i think theres no bottoning here what can you say. its just a cluch problem and we ran out of ideas but we will not give up, i believe theres always a solution you... the Guru of Jeep. Thanks.. Mario Bedayo Quote Link to comment Share on other sites More sharing options...
Administrators Moses Ludel Posted October 21, 2016 Administrators Share Posted October 21, 2016 I answered your question about the pilot bearing...You do need a crankshaft pilot bearing...This will keep the transmission's input gear aligned with the crankshaft...
