Hey guys,

Quick question.

I'm checking my 3-4 clearance (dry)
and I am getting right around .035"
I'm using 7 x.065" Bw HE friction
6 x.095" frictions
.192" backing plate
.092" snap ring
.220 apply plate

Does the clearance sound right? Everywhere I read indicates I should've had around .065" of clearance using a standard 4l65e stack. Do you guys use a feeler gauge between the snap ring and the backing plate to check clearance correct? Or is it between backing plate and the friction? Sorry for the noob questions.
trying to aim for .025-.030" clearance atm.
using the 1.530 "overall height as a guide btw, seems like this stack gets me right at 1.53

 

Did you intend for 6 x.095"frictions to say 6 x.095 steels?

.035 is good, set band clearance around .060 to .070. to two clearances work together.

 

Yes steels* sorry. Was late when I wrote that

Well my question is, shouldn't my clearance be much greater with that stack?

 

If you have a spare .106 plate that will take up .010 clearance. That's the setup I run a lot. 6) .065 frictions, 5) .095 steels and 1) .106 steel. Once the frictions are wet and compress a little you'll be around .035 clearance.
With 6.095 steels you end up around .045-.050 after wet and compressed.

 

Thank you for the info
is checking between backing plate and the snap ring a proper way to check?

 

I don't think it really matters which way you check it. I check between backing plate and the friction, but you need to be careful that you're not putting so much pressure that you **** the other side of the clutch pack.

 

you probably think I'm an idiot but I damaged the surface of the friction sticking feeler gauges in between the plate and the friction. I also checked the clearance with the 5 return springs. Is that the right way of doing it or do I omit the springs just for checking?

 

I use an old Mopar 518 rear checking tool. It's a long flat bar with a slot int it. It fits across the drum Then you can measure the actual friction movement from released to applied with a dial indicator.

Nice!

 

It is often small things that experience teaches you...

When you want to use Feeler-gauges to check Clutch Clearance...
Do not alternate the last Friction and Steel before the Backing-Plate...
Instead (from the Backing-Plate down) use a Steel, Steel, Friction, Friction, and then the rest of the Stack.

Now you will avoid cutting any of the Frictions with the Feeler-gauges (they will be between two Steels).

Also...
The Modern (1-piece) Apply Plate only goes one way.
Most of the thicker Backing Plates only go one way...
But some of the thinner Backing Plates will go either way.

Just look carefully.

 

This probably doesn't need to be said, but there is always that one guy. Once you are done checking your clearances don't forget to disassemble clutch pack and rearrange pack to steel, friction, steel, friction, steel, friction.

 

Very true.


Although...
You guys better be disassembling from that point anyway to soak your Friction Elements.

 

I ended up stacking all frictions together and all plates together to check clearance lol then I come in after the fact and u pretty much say the same thing (end with a steel) ,thanks vorteciroc !

 

I love tools that ensure work accuracy .....could you make a vid of it in action ?

 

I ordered a tripod to hold my phone. I'll give it a shot after it arrives and I'll post it here...

 

I could not upload a MP4 video file so here is a link to a you tube video on how I check the 3-4 clearance. It's my first one, I hope the link works.
