Ironhead Clutch Stud Spacer: 1.530" pn #5995, 0.040" #5996, 0.080" #5997

[XLXLXL]

hello folks,

there are three different clutch stud spacers, how are we using them, and under what circumstances?

is it oversize (0.040and 0.080) or decreased sized (-.040 and -.080)?

I bought alto clutch, I measure each plate 2.45mm, and bought another brand I measure 2.35

I need to learn the combination between friction plate ad the different stud

thanks for the respond

Go with the standard size 1.530.

The different length sleeves are to adjust the pressure plate position, likely to compensate for clutch pack thickness differences.

Clutch assy/disc thickness is measured as a stack, fibers and steels together.

Converting early clutches to use sleeves is my preferred setup, as the sleeves help to get the clutch to release flat by providing a uniform clamping height. It takes a lot of the fiddlling out of clutch setup and also reduces the rotating weight of the clutch.

that's the idea.

noted that about "measured as stack" thx

these will mushroom over time.
i usually will make my own when i need them.

Yes the sleeves will crush so don't get manly on the nuts.
And always use new nylock nuts.
Careful making your own spacers, exact uniform length is needed, OD is critical as you do not want the sleeve to drag on the steel.

when you have that resource, maybe good to work on milling or lathe

thx for the advice on using the nylock nuts. it is 1/4 - 20 right?

[ryder rick]

Yes 1/4 x 20.

The sleeve length difference is ~half the thickness of a steel. So that gives you some wiggle room on stack height.

For when adding or removing a disc would put the stack out of spec.

They don't call me Ironhead Rick just because I'm hard headed
