First try at replacing a clutch

Seems I am going to have to replace this clutch. I've only had this truck about eight months and I don't really know what the history of the clutch is. I do know that it's gotten hard to shift and makes noises when stopped with the clutch down. My best description of the noise is when you're pushing a lawn mower and you accidentally run over a piece of paper. The noise makes me think something may have broken off the clutch And is flying around inside the bell. I've tried lengthening the clutch Rod Adjustment and that made it shift a little easier but I still have the noise and struggle to get it in gear when stopped. I have a few questions pardon me if I don't know the proper terminology cuz I have zero training and am basically teaching myself this stuff

I have a three speed transmission and it looks like two of the bolts go in to it from inside of the bell housing. I assume that I have to take the pan off the bottom of the bell housing and then I should be able to get to those bolt heads from inside?

Is it better to remove the pins on the shifter linkage arms or unbolt the bolts that go through the shifter arms into the transmission when removing the transmission?

I will likely pick up a clutch kit after I've taken it all apart. Is there a recommended brand? I'm not looking for high speed our performance just solid functionality.

Are there preventive maintenance things I should consider doing since I'm going to have the transmission and clutch out?

I'm sure I'll have more questions and appreciate the input.

Re: First try at replacing a clutch

You nailed it about the bolts come out from the inside. I don't think you are going to have any problems.
Remove the keepers or cotter pins from the shift rods rather the taking off the levers.
I have real good luck with Carquest clutches. You may want to change the lube in the trans. & rear end while you are under there. If you drain the trans. before you pull it you wont get it all over yourself or the floor. If any of the trans seals are leaking now is the time to replace them. If there are any leaks in the engine that are getting oil on the clutch, you need to fix them. Oil can ruin a clutch.

Re: First try at replacing a clutch

Check the flywheel for checking, glazing or cracking. It probably should be surfaced to get the best out of a new clutch.

Definitely, surface the flywheel, even if you don't think it needs it. Your clutch will last longer. You need a clutch disk and pressure plate, a pilot bearing, and a throwout bearing. You also should buy a clutch guide; it will make installation a whole lot easier.

An old mechanic's trick to remove the pilot bearing is to pack it with grease, then place a bolt or a punch close to the inside diameter in the bearing and give it a smack with a hammer. The hydraulic pressure will drive the pilot bearing out.

Make sure you follow any recommended torque sequence and specs when you're reinstalling the clutch.

Re: First try at replacing a clutch

I've not even started but have a few more questions

- there is an electrical connection(spade) next to one of the shifter levers with nothing connected. What was supposed to be there?

-where can I find the recommended torque info for the clutch related bolts?

-the truck does lose some oil. Drips from the cover under the bell. What is the likelihood I am going to find that the oil leak will require an engine tear down to locate?

Thx

The electrical connection is your reverse lights. If you plan to keep your truck for a while, get one with a lifetime warranty. In the last 17 years I've replaced mine three times for free. Torque Specs.

Re: First try at replacing a clutch

It is possible that you only need a new throwout bearing. I don't know what your financial approach to this project is, but there was a day when I would drop a tranny just to fix what was broken (because buying parts was prohibitive for my wallet), and leave a clutch alone if it's not slipping. Now, my time is worth more than parts, so if I tear it down, it's getting rebuilt fully.

If you've got oil in your clutch, you've got to figure out where it's coming from and fix it. It could be a trans seal, rear main seal, oil pan gasket, or if you're lucky, it's a bad pcv hose that's just dripping down the bellhousing and not on your clutch at all.

If you are replacing the disk and pressure plate, I agree that name brand parts make a difference in the long run. Also know that aftermarket "muscle car" and "racing" clutches may have considerably more pedal effort required to operate, which can make them strong but hard to live with.

Expensive lessons are not soon forgotten
