Truck wont go in Gear!!!! NV4500 conversion Issue

[MrWinkey]

OK I get everything done. transmission is in T-case is in. Everything is buttoned up. I go to fire up the truck to take it for a quick drive and the truck wont go in gear. Ok... . so I turn off the truck it goes into gear off. If I turn on the truck with it in gear it moves.



So what did I do wrong?



I can look through the belhousing and see the Throwout bearing working on the PP. Everything looks ok. Could it be that the throw out bearing just isnt going in far enough to the PP?



Let me know guys... ... I'm sure I did something wrong.

which hydraulics are you using? if everything is bled properly, you might try shimming the pushrod on the slave cylinder to get a little extra travel. but you really shouldn't have to do that if everything is synched up properly

transmission issue

Your description sounds like the clutch isn't clearing or something is draging so that the input isn't stopping. (Pilot bearing too tight) HOPE you can get a bit more clutch travel and solve the prob. Is the clutch rod moving as soon as you begin to press the pedal? You may have ingested some air into the system.

Yes the piston moves. Throw out bearing depresses the PP. How do I bleed air from the system? The piston had fallen out of the cyl when I went to reassemble it.



It shouldnt be the pilot bearing issue as I have the bushing in it.

 

[MrWinkey]

I'll shim the slave cyl a lil tonight.



I bet I Put in the clutch disk backwards tho... ... .

I had the same problem and it was the pilot bearing. Luck helped me out. I had put a lot of synthetic grease in the bearing and it finally broke loose with no apparent damage. The first hint of a problem was the diffulculty of getting the last 3/4 inch of the transmission installed. I chalked it up to doing the install by myself and old age. That last part was true, but the bearing was still tight. The Getrag bearing had over . 030" clearance. The 4500 bearing was . oo5". Not enough I guess. Good Luck

Putting the disc in backwards shouldn't account for it not disengaging. Did the bellhousing and trans slide in tight easily without a lot of force? The conversion instructions I had when I did the 92 said to cut the sleve around the imput shaft down shorter. I don't remember the dimentions but they came with the Advance adapters stuff. If you didn't shorten that tube and had to force things together it could cause a bind that would feel as if the clutch were dragging and give the symptoms you describe.

BSchindler: Did you use the new ball Pilot bearing from Quad 4x4? Qu51010 Ball Pilot Bearing? I thought that bearing should take care of any issues like that.



It slid in very easy to the last 1/2 of an inch and then it went in a little tighter.



The clutch wont disengage at all. With the truck running it will not go into gear. With the truck turned off and in gear you cant turn the driveshaft when the clutch is depressed.



Should I try and take it out and put a little grease on the clutch splines and in the pilot bearing?



SRadke: Quad 4x4 already cut down the input shaft and everything. It should just bolt together and work..... Dan @ Quad 4x4 has been very helpfull and given me a few things to try also.



After looking at my old clutch I think I put the new one in correctly.....

Did you try putting it in gear and starting the clutch while the clutch is depressed? I'm curious if the cluth is not disengaging at all or just dragging enough that the syncros can't overcome it.



WARNING!!! If you try the above be prepared for the truck to begin moving upon startup! If you drive it through the garage don't say I didn't warn you

I did a similar test as I dont have anywhere safe to do the fire it up in gear w/ the pedal down test.



I would put it in gear and then release the parking brake. (it's on a slight slope)



The truck wouldnt roll back with the clutch depressed or not. Basicly like it was in gear the whole time. With the clutch down and in gear the starter will bump the truck forward.

Clutch draging

As I think on what you have posted, the thing that comes to mind is that any time I have installed a transmission, the last 1/2 inch is the easy one. You might as well pull the transmission and see what is wrong. On most clutches, if you put it in backwards, it would bind to the point that it would be hard to put the pressure plate bolts in all the way. The center section of the clutch would obstruct against the center of the flywheel. I recalled from a previous post about having to shorten the throwout collar. I think that may have already been done on some kits. Hope you can resolve the problem without serious rework.

My kit was from Standard Transmission. Most of the kit was supplied to them by Advance Adapters (Calif. ). My original pilot bearing was a bronze bushing and the replacement was aswell. Just a standard "Bunting" bushing. The way you describe your initial start-up sounds just like mine. But, when I started it the second time (in gear), the truck started to move with the clutch in. By applying the brakes, the pilot bearing broke loose. This is a little risky (snapping off the nose of the input shaft) ,but I had reviewed all that had been done and felt fairly safe. Lucky too. Hope you can resolve this problem. If you have a engine barring tool, maybe you can look in the bell housing while a helper turns the engine over.

DOH... ...



Took it apart last night... . Clutch disk in backwards...



That's what I get for putting it together in a hurry in the dark... ... .



PB do I get a -5 HP deduction for that?

 

[Forrest Nearing]

nope, you get an additional 10hp for not *****ing about it and diving in and getting dirty!

Mine did the exact same thing - Peter at SBC said hydraulics but I didn't think so. I took it all apart measured everything no problems there so I tried 2 different NAPA slave cylinders - no help there. Well Peter was right - when I bought a new Dodge Clutch master slave cylinder the problem was solved.

[MrWinkey]

Truck is back together. transmission works great w/ the clutch disc going the correct way. Drove it down my driveway and back. That NV4500 makes a world of diffrence. Snaps in and out of gear compared to my old getrag.



I would like to thank you guys from the TDR and Dan from quad 4x4.....



I'm going to go lay down in a hot bath..... my back's a lil sore.
