Evan Purple240zt Posted March 22, 2008 Share Posted March 22, 2008 Was it an auto tranny before? Sounds like the auto tranny pilot is in your way. You must run a pilot bearing. Evan Quote Link to comment Share on other sites More sharing options...

If you have a pilot bush in the rear of the crank already, you will not be able to insert the new one without first removing the old one. If you never had one in the rear of the crank, then listen to the above post. No matter which way it is right now, you shouldn't be bolting your pilot bush into the motor... Please explain your situation better if this did not help you with the install. Quote Link to comment Share on other sites More sharing options...
voltron_boi Posted March 24, 2008 Author Share Posted March 24, 2008 if the rb25 engine was an auto before, how can i switch it into a manual engine, what part will need to be taken off, so the manual pilot bush would bolt in. if this is compacated i will post pictuer later, so u guys will get a better veiw at it. thax Quote Link to comment Share on other sites More sharing options...
pirate87 Posted March 24, 2008 Share Posted March 24, 2008 The auto RB25 bushing is a major PITA to remove, I broke 2 bearing pullers before I decided to just grind it out. Good luck, I hope yours is easier to remove than mine was. Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted March 24, 2008 Share Posted March 24, 2008 Generally cutting it out is the best way. Maybe a jigsaw with a cut down blade would fit in the area. Best of luck man, its a pain to remove as Pirate87 warned! Evan Quote Link to comment Share on other sites More sharing options...
scottyMIz Posted March 24, 2008 Share Posted March 24, 2008 i used a flat chisel and a hammer on mine making a score down the inside of it and then just kept taking a bit more off each time til it got weak enuf or went thru the bearing then used a smaller chisel and bent the two sides in to kinda crush it then it came right out. But it does take time and as stated is a pain in the butt Quote Link to comment Share on other sites More sharing options...
voltron_boi Posted March 24, 2008 Author Share Posted March 24, 2008 i want to confirm if this is an auto or a manul before i start griding the auto piolt bearing. Quote Link to comment Share on other sites More sharing options...
scottyMIz Posted March 24, 2008 Share Posted March 24, 2008 the bearing is tapped into place, i have never seen one without the flywheel on but it looks like that part sticking out needs to come out in order for your bearing to fit. Quote Link to comment Share on other sites More sharing options...
voltron_boi Posted March 24, 2008 Author Share Posted March 24, 2008 my second option is thinking that i should use a thermal to make that hole larger so the manual pilot bush would go in. any suggestion before i do that. Quote Link to comment Share on other sites More sharing options...
scottyMIz Posted March 24, 2008 Share Posted March 24, 2008 dont make the hole bigger all the cranks are the same they can be used for either manual or auto that bushing doesnt slide in it gets tapped in with a hammer and a piece of wood or a soft surface hammer.

voltron_boi Posted March 25, 2008 Author Share Posted March 25, 2008 last night we dermal the hole a lot larger. now can we fit the pilot bush in. but now the pilot bush have cracks on it. plus when putting the tranny on, tranny does not go in all the way. it fits the long tips but rite after the tip it doesnt go in anymore.any suggestion hybridz.

jtmny1999 Posted March 25, 2008 Share Posted March 25, 2008 From the pictures you posted I see another pilot bushing in there already. You have to remove that one or else the new one wont fit all the way in, so the input shaft will be stuck not fitting properly. -JT Quote Link to comment Share on other sites More sharing options...

Did you use the clutch alignment tool? if you didn't then it will also cause problems going in. Quote Link to comment Share on other sites More sharing options...
voltron_boi Posted March 26, 2008 Author Share Posted March 26, 2008 yeah but the pilot bush on the crank is longer(goes all the way into the wall) and a little bigger then the oem one where its short.ets me frustared, so my last option is, just using the pilot bush that is already on the motor.

Evan Purple240zt Posted March 26, 2008 Share Posted March 26, 2008 You have damaged your pilot bushing, pull it back out. FYI you can use one from any nissan for the most part (ie 240sx). If you don't cut the old bushing out the trans will NOT slide on all the way and it will bind against the input shaft. The answer is covered in the beginning of your post.
