Hey guys,

Just needed some help here. I have a 1982 ford f250 with the 400 and a manual transmission. When I engage the clutch I hear a squealing/spinning noise. Its really loud in the cab. The transmission shifts great. What could this noise be? I just dropped a new transmission in last summer. Is it the throwout bearing? Any ideas I need to fix this and the brakes ASAP. Thanks,

-Evan

 

From your description I would think it is a bad throwout bearing.

 

It might not be a bad throw out bearing it might just need some grease.

Pull the boot off the clutch fork, and ever so carefully try and lube up the transmission input shaft. Heavy grease will work best; but for test purposes, use a canned product with a straw (it MUST have a straw) don't get it on the clutch material!....

Since your truck is a big block, its probably has the NP235, or T-18 4speed with a granny gear, both are heavy transmissions, but easy to remove and install.

If the grease doesn't work your going to have to pull the trans. From inside the cab unscrew the shift boot, and remove it along with any insulating foam. The shift stick retainer unscrews to remove the stick. when you remove the stick carefully remove the alignment dowel pin and put it in a small ziplock bag and put it someplace safe.

Drain the trans fluid, disconnected the springs on the clutch linkage, and unbolt the drive-shaft 1/2" nuts from the trans or both from the transfer case for a 4x4. If its a 4x4 unbolt the transfer case 4x4 shift lever, and t-case bolts 9/16", then drain it, and remove it.

There are four bolts on the trans, unbolt them 5/8", along with the bolts on the transmission mount, cross beam. use a big jack to hold up the tail end of the trans and remove the transmission mount. Use another jack and a block of wood to support the engine by the oil pan (block of wood under the pan) You want to keep the engine the same height for easy reinstall of the trans. Disconnect the reverse light connector. Remove the jack from the tail of the trans.

The T-18 and NP235 are about 240lbs dry; use your head have someone help you. Remove the transmission. The throw-out bearing will be left hanging on the clutch fork.

NEVER EVER get a plastic throw out bearing they are CHEAP for a reason...they break. Spend a few bucks and get the 30$ metal one.

When putting the new bearing in grease the inside diameter of the hole, and the front disc surface that contacts the pressure plate. also apply a THIN layer of grease to the transmission splines, and bearing retainer sleeve that the bearing rides on. Reverse the removal procedure and test it all out.

Sorry for the long post but I just wanted to give a good explanation of what you may have to do. If you have a 4x4 you will need a new t-case to transmission gasket. No Special tools required, but off-set ratcheting wrenches will help a lot.

Tools Needed: 1/2, 5/8, 9/16, (4x4 linkage only: 1" OR 1 1/8") 7/16. You might need a few others just but those are a must.

You'd also do good to replace the clutch Z-bar nylon bushing at this time.

I hope this helps and above all this post isn't to offend you if you already know how to take a trans out. Good Luck!
