315 hours on my 3620H ROPS today and I noticed during the day a reduction in hand throttle lever friction then at some point it went completely away and there was about a 40% piece of plastic washer on the floorboard just under the throttle lever which I'm assuming is the friction disk. I looked thru the service manual that was posted here by Asteral and I didn't find any parts diagram for this lever assembly.

Can someone explain what the procedure for replacement is? Based on the piece I found, I should be able to make something equivalent in size and thickness to get me by until a replacement part can be obtained. Are there any special tricks I need to know about when opening up the dash panels and replacing the friction disk.
Thanks.

If like my 2400H it is just sandwiched between a couple of steel washers and has a wave washer for setting tension or friction. On mine hardest part is getting my fat fingers in the area where the washer goes.

Got it fixed with a large washer I made from an old 5 gallon paint can lid then sandwiched it between 2 fender washers. Will have to see how it holds up in the heat.
Access was easy with removal of instrument cluster and right side dash panel.
