 Topic: Hand Clutch Question
Posted: 14 Jul 2010 at 7:43am |
|
My neighbor has a D-15 that he bought recently. First one I have seen up close . The hand clutch was "worked on" by the former owner and it has only the two speed function with no neutral or middle position like my D-14? That seems strange. What's likely to have been done? I also noticed his foot clutch engages hard almost as soon as you think about lifting your foot. Is the hand cluch possibly an adjustment issue?

Maybe the best thing for him to do would be to sell it to me and I'll figure it out. LOL I don't know about adjusting the hand clutch but somebody with experience will chime in here.

When you remove shims from a power director clutch, you must add the same amount in thickness to the center or neutral, this is probably the problem. Also the center shims and the high/low shims are different, thats why sometimes people remove the ones from the high/low side and don`t have the ones to reinstall in the center.
Hope this helps.

Listen closely to what is said above about the shims. I never had to do that but when we attended the factory school on power director they stressed that shims removed from one side had to be replaced in the middle so that the exact adjustment would be maintained. If I can recall it had to do with the linkage.
Good Luck!

I would expect the D15 hand clutch to act just like the D14 hand clutch....they are exactly the same. I'd guess they do not have the proper total of .205" shim stack at each of three locations, which if less than .205 will make neutral pretty small. Foot clutch on the D15 is a button clutch which is more aggressive the a D14 fiber clutch.

Is there a way to get into the shims from the side cover or is this a split the tube to fix?

Yup.....just pull the cover off behind ther hand clutch lever....may have to drain the 2 gallons of oil.........drain plug under the clutch pedal...takes 1 1/8" wrench.

What you move from on side you add to the other is correct. The reason for this is so the overall thickness of the power director stays the same. If you dont add what you take out, this makes the clutch thinner, which in turn makes the linkages longer(or vice versa), and keeps it from snapping over center.
Shims between the center plates are longer(to help support the center plates) than those at the actual clutch discs. If you install the longer shims at the clutch disc location the long shims will actually cover the clutch disc lining, which can cause slippage. In a pinch you can take a pair of tin snips and shorten the long shims up to make them work, although I dont recommend this

The key is there are SHORT shims in the front and rear locations and LONG shims in the center location. If you add up the total thicknesses of all three shim stacks (let's say .060" rear(hi range) and .060" center(neutral) and .085" front(low range) ) it has to be .205". Remember there are THREE shim areas and each area has THREE shim stacks. Whenever you remove a shim from the front or rear, you MUST add the same amount (thickness) to the center to maintain the .205" total.
