Tips Needed: Clutch Install - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Gumby'sC20 · 02-04-2009, 01:43 AM

Alright folks,

You may remember a few weeks back I posted stating I was having issues shifting, and a few days ago posted about my clutch completely failing. Well, I'm moving forward now and have ordered my new clutch kit, complete with everything needed for a fresh, flawless setup.

As far as the installation goes...that comes as the job me and friends will tackle this weekend. However, we are attempting this in my driveway [obviously no car lift], under the truck pretty much for hours...trying to get my beast moving again.

Any tips or advice, anything I should be aware of for a clean installation?

I appreciate it! Thanks in advance

Take the time and have your flywheel resurfaced before installing the clutch. Its a time consuming job if its your first time. Just disconnect the Battery, remove the starter, Drive shaft, crossmember ( if you have one), clutch linkage, 4 bolts for trans, the 8 or so on the bell housing. Then the clutch and then flywheel. If you have an old yoke stick it in the rear of the trans so you dont get gear oil everywhere. Also change the pilot bearing in the end of the crank. then reverse the process and go go go. Good luck. Ive got 2 flywheels so I keep one surfaced so I have done the turn around in about 4 or 5 hrs.

The key is to plan it carefully before you start.

As I got older the most important thing I did was to rent a transmission jack from a rental place. Makes it almost effortless.

Also, don't forget a good quality clutch installing tool to aline the clutch plate. I used a cheap plastic one once and it was worthless. A solid one is better. I have an input shaft of an old transmission that I use.

Other than that, it's pretty much as smoked68 and truckdude239 said.

If you have a floor jack you can get an adapter like this for pretty cheap: http://www.jcwhitney.com/webapp/wcs/...atalogId=10101
I have never rented a transmission jack, so that may be cheaper. Guess it depends on how many time you think you will use it.

You should use wheel chocks weather you're on a flat surface or not."SH!T HAPPENS" Better to be safe than sorry. Set your park brake also. Like to hear about you driving it rather than laid-up and hurt.

read your service manual and become familiar with the proper steps in installing the clutch and proper adjustment procedure // just go step by step the way it's listed and you won't have a problem

You didnt say weather it is a 3 speed or 4 speed. I gather its 67-72. You dont have to pull the bell housing on these. Just pull the trans. out & remove the clutch from out the bottom of the housing. Then you can pull the flywheel out too if you are going to have it surfaced. Sometimes the flywheel wont quite clear. You can grind a little groove in the houseing to get it out. With a 3 speed this is the easiest clutch job you will ever do.
