spacers
'45 mb had spacers between press.plt./flywheel. had lots of power. They were tossed during a clutch change out. Jeep has never had the power like before. Need to know the size of the spacer if anyone has the same setup. Press.plt. bolts through Plate,through spacers(6) into flywheel.

Re: spacers
Obviously not a stock 45 jeep option. Whose clutch? was it a single disc or dual disc setup.

Re: spacers
I've had it since the early 70's and it came to me that way. Everything else is standard. Had several clutch changes over time and always replaced the spacers. Mistake was to have someone else do a change and spacers were gone. Jeep doesn't have the power that it had. Currently had flywheel faced, new plate, disc, carrier/bearing. Plate fingers set at 27/32 to inside plate. About to get new body and want everything in real good order.

Re: spacers
I have no idea why they were there . But the power/torque was never the same without them. Any how I'll re- measure the fingers. Hopefully I get the right measurement at the right spots. Everything new so it should work out fine.

Re: spacers

I think what has folks scratching their heads is that a properly operating clutch/pressure plate assembly has nothing to do with increasing or decreasing the power or torque produced by the engine?
The sole function of the clutch, when engaged, is to transmit the torque produced by the engine to the input shaft of the transmission. As long as it's not "slipping", that is the end of the story.
Power and torque are an "engine tune" thing not a clutch thing.
A "slipping clutch", however, can feel like a loss of power!!
Are you experiencing this "loss of power/torque" while driving? (Typically trying to accelerate)
If so, I can suggest a test for that.

Re: spacers
Right.
I want the OP to explain the spacer theory and how they increased power.
If it does, it will defy the laws of physics.

Re: spacers
I agree with all the response. I have no idea why they were there. And lack of power must be due to adjustments. The jeep is hardly driven because of the problem. I will post future outcome at a later date, hopefully soon. Thanks to all !

Re: spacers
The only reason I can see to fit spacers under a clutch cover (UK parlance) is to allow enough clearance to release the clutch plate if it were a wrong fitment - too thick or something. Definitely a 'bodge'.

Re: spacers
Could it be that the clutch plate was fitted the wrong way round and that instead of turning it over, the "mechanic" fitted spacers so the clutch did disengage.
The chap who replaced that set up has done it the right way round. Hope he also changed the bolts for shorter ones

Re: spacers
some clutches are made for a flywheel with 2 different level surfaces. the disc sat in a recess, so there you would need spacers if you use this clutch with a flat flywheel.
Also some multi disc clutches use spacers since the discs need more room.
you will never know what was in there unless you have the old parts.

Re: spacers
I call them stepped & flat flywheels, Adam. Jeeps I now of are flat.
Like the others here, I don't see the connection between the spacers and power change.
I have no clue why the spacers where there with the old cover. ???
Can only imagine.
Jeep clutches normally don't have spacers but, yours did. And I assume ( there's that word ) the clutch worked OK ???
Now you have changed the old clutch assembly for a new one.
Without spacers. Does this clutch function normally ??
Release and engage like it should ??
If so, installing spacers on the new clutch assembly may cause you grief.
If you space a clutch cover away from the flywheel, two things happen.
1. Before the cover is tightened down by the bolts, there is a gap between the cover & flywheel. That is because the pressure plate comes into contact with the clutch disc before the cover seats up to the flywheel. When the bolts are tightened, the cover seats in place and the plate is pushed into the cover, against the springs, squeezing the plate between the plate & flywheel.
So, if you space the cover up, less pressure on the disc because it is not pushed into the cover as far and the disc might slip.
2. Since the plate is not pressed into the cover as far, because of the spacers, the fingers in the cover will not move down as far. Finger height will be too high.
Don't know what cover assembly you had before but it may have used spacers and don't know what cover you have now but it may not need spacers.
Then, there is the question of, Why you lost power.

Re: spacers
If you do change the clutch you have, I can say that the clutch kit I bought from Ron has been great.
Smooth engagement for 5 years running.

Re: spacers
Power loss is another issue, these jeeps were owned by many different types of people, farmer types who would take a clutch for a stepped flywheel, say from an amc eagle or something like that, and since it was laying around doing nothing and the jeep needed a clutch he would put it in there, some spacers between the pressure plate and flywheel and he got it to work. Not correct parts, but it worked.
