I liked my 76 better when it had 53's for sure. One person could roll it with out much of a fight. It'll be easy now until I get an engine in it. :lol:

Any progress on this baby yet?

Nope gotta pull the transmission out and look at the clutch. Dunno when that is going to happen with school and work right now.

Well good luck with it man!

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Well I got the transmission pulled out of the truck tonight. After looking at the clutch and noticing there was nothing wrong with it I came home and looked at some stuff and I think I have found that the 6.2 will use a different pressure plate than a 350. Im going to pick one up this week some time so hopefully I will be able to get the truck up and working correctly soon.

Do you have a 6.2L flywheel on there?

Mattman2010 12-13-2011 09:07 AM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Yes I do. I called the guy I got the 6.2 from and he said that he used his big block clutch and it worked fine. So we got to looking (He works at oriellys) and we found out that the 6.2 and the 454 will use the same clutch and that clutch can also be used on the 350, but the clutch that I have seems to be for a 350 and not used on the 454 or the 6.2. I am going to take my clutch in to see if it is any different than the one they have.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
How much is a clutch? Seeing how you have it torn apart, you might as well replace it with the correct clutch so you know what you have.

Mattman2010 12-13-2011 04:50 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
They are $109 for the whole clutch, but as I have told you it is the exact same one that I have currently. I have narrowed it down to not getting enough stroke out of my current setup. My clutch is not in bad shape so I am just going to leave it alone and try to figure out how to get the stroke I need. I may have to move to a smaller bore slave.

1985-GMC 12-13-2011 05:11 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Or bigger bore master..

Are you going to try to lengthen your rod on your slave first?

1985-GMC 12-13-2011 08:53 PM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Yeah I was going to suggest that. I'll try to find the thread where someone did a pretty clean job of it.

Yes before I go modifying everything else I am going to try to lengthen the rod and see if that will work. If it doesn't than I will have to find a way to get more movement out of the slave.

That would be awesome if you could find that thread. I have the idea of using the old rod off of the mechanical linkage because it is a 3/8 bolt. Im just not sure how to go about making the adjustment part.

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Well I went ahead and bought a new clutch pack for the truck and then put the transmission back into the truck. Turns out it worked the first time, I am not sure why it would not work with the old clutch pack, but it now works. Hopefully it will continue to work.

Sweet, that's always a relief!

You don't know how irritated i was getting with this thing, i kept looking at the fuel tank and lighter. I was going to burn it down, but decided just to put it back together to see what would happen.

1985-GMC 12-19-2011 12:23 AM

Re: 85 GMC Sierra Classic 1 Ton Crew Cab
 
Haha good choice!

I have a little bit of an idea. :lol: I'm glad you got it fixed!

Yeah, you might have some idea :lol:

Well today I went to start the truck and it started cranking really slowly and then i tried it again it the starter motor burnt up. So $170 later I got a new starter in the truck and it starts like a dream! I think the old starter was on its last bit and I finally killed it, every once in a while it would turn the engine over very slowly and was hard to start and other times it would turn the motor good. But now it burnt up and the new starter runs like a champ.

I've decided to keep the project, so I dove back into it again yesterday. First thing was fixing my steering box. It blew a seal and so i fixed that but for some reason the seal has already popped again so I am going to just get a new steering box.

I also have decided that 6 tires is just to much. So I took the bed off and slapped some singles on the back. Yes I am using a dually axle with singles on it, the rear tires I believe the rear axle is 3 inches total wider than the front, so about 1.5 on each side. I dont like how the rear tires tuck under the bed and the front ones stick out so this should hopefully stick them out and make it look better in my opinion. I dropped my good SRW long bed, but I am going to see if I cant bend the parts that are folded in close to where they need to be for now and then maybe find a whole new bed or a good bed side.

I was out seeing if I could tell a difference with the singles. I guess it helps not having the bed on so it road smoother and I decided to do some flexing.

So sunday I am hoping to get a new steering box and get the bed on. Then put my dynamat in the truck and get some heat in it finally.
