Engine/Transmission (1994 - 1998) Installed #6 Plate

[Oil Ape]

I have a general plate question.



I just installed the #6 plate and it seems to work great with little to no smoke. In the instructions however, it said upon reinstallation of the AFC housing to slide it as far forward as possible. I installed it in the same location as it was installed stock. What is the advantage or what would it do if I did slide it all the way forward. Thanks...

Sliding it forward will give you somewhat better low end power

 

[Oil Ape]

But would it smoke more? Would I then have to adjust the starwheel?

 

[Rammin On]

It's possible ... . slide it forward ... then turn your starwheel all the way out ... drive the truck and adjust the starwheel back until you get the desired smoke/response that suits you.

 

[Oil Ape]

I guess another question would be how much do you adjust the star wheel at a time?

 

[Rammin On]

You can see the starwheel in the hole ... when it's loose it will be all the way forward in the hole ... . turn it back about 1/4 of the way for your first adjustment ... see what you have ... then you can start going at it slower . .

When you "adjust" your star wheels, is it like- you drive around the block, come home, take everything off the housing, rotate the wheel, put everything back on, drive again, etc. . Does anyone have a Prime Loc and do this? Must be a pain, cuz when I did my 3000 gsks I was praying my idle would be okay so I would have to go back in.

Just sliding the housing forward does 2 things.

1. It allows more forward travel of the foot. This allows more fueling via your #6 plate once boost is up and the foot moves forward.

2. It also moves the zero boost point up and gives you more off-idle performance.



Does it smoke, yes. Can you control it, yes.

I followed PDR (Piers & Al) advice and only slid it about 2/3 forward.

I moved the starwheel a few clicks forward (looser).

Very controlable smoke.

Kalaehina,



There is a big plug on top of the AFC. Get yourself a big allen key that fits. With that out a screwdriver will turn the star wheel thru the hole.

What bighammer said, plus the prime lok set-up would not be in the way to make this adjustment.

I finally gave up on the Prime lock! It was always in the way when I went to do anything. Move the plate = move the prime lock. Move the AFC = move the prime lock. Change the AFC spring = move the prime lock. Grind a new profile on the plate = move the prime lock. I threw it away and went with the stock set up.

The prime lock was the first add on I bought. It was a bad first choice. After you get acquainted with the 12 valve motor, whats the big deal with changing the stock fuel filter. I can change one in about 10 minutes now.

Your right about the Prime Loc being in the way for most adjustments. I was simply pointing out that to get the top plug out to adjust the star wheel, it's not an issue. As far as other adjustments go, you still need to remove the same number of bolts in most cases, however the Prime Loc is still a hindrance since it has to be moved aside, and even then is a bit of a nuisance. Kind of like boats, there is not one made that can do it all (dingy VS yacht). The same about the location of the fuel filter on these engines. I for one like the power and reliability of the Cummins enough to not fuss to much about the fuel filter location.
