I've been in touch with Roy at QDS via email and phone, and over the course of many emails, we have come up with a list of parts for two different scenarios.
The service he has provided is second to none and his patience with my lack of knowledge and understanding is great. He has helped me to figure out what's best by looking at some pictures and reading Torque and HP specs on the diesel engine.
Thus I'm just about to order enough parts for both Gas and Diesel engine 780 Drive, and a couple parts for the 770 driven clutch I have to test with. The 770 had quite a lot of rust on the sheaves and though sanded off and cleaned up it still isn't as nice as I"d like. So if this works OK then I can later order a new 770 and if I still don't have enough LOW gearing a 11 1/4" dia 860 driven.
Parts list as follows...
DRIVEN PARTS:
1 - 703102 - Spring-Black $ 20.00
1 - 703831 - Cam Slipper(3 PER) 3.00
Gas ENGINE Clutch
DRIVE components:
1 - 164-0005 - Weight Asy.-Kit-91grm (3 PER) $ 45.00
Diesel ENGINE Clutch
DRIVE components for 900 RPM engage:
1 - 602253 - Roller wieght asy. (105 grms) 3 per $ 65.00
1 - 703548/49 - Spring kit (green) 35.00
Total for all $168.00
I'll order the 3/4" to 7/8" adapter for my driven clutch as well, that takes me to near 200 bucks for the clutching on my machine, and allows for two engine combinations. First is the gasser setup and then I can work on adding turbo diesel.
Well damn if that aint a bad price for essentially a 3 clutch setup!
Lastly will be locating a new belt for the larger secondary setup. That should be quite fun here we have ID 10 T's for people who work at parts places ROFL
