A few years ago I purchased a, what I think is a Muncie 319 with the Borg Warner R10 overdrive in supposed good working order, he apparently only removed it to put in a T5. I stripped it down today to give it a freshen up before use and my opinion of good working order is a bit different to the sellers. This is what I found. Is there a supplier that has sun and planetary gears, or has anyone discovered a setup using gears from an automatic that are easily available. I am Australian based but will be surprised if I don't have to buy from the states. Thanks for any help Steve
Van pelt probably has em. More than likely used. Most of the r10 set ups seem to share the same parts beteeen makes. Output shafts being brand specific.
At the moment we probably have 3-4 nice good used planetary gears in stock, and plenty of nice used sun gears. It’s impossible to tell from the picture whether the freewheel cam assembly is still okay or not. It needs to be removed from the planetary gear (remove the U clip) then cleaned and inspected. Good freewheel cams are just about as hard to find as good planetary gears. If you’re in Australia just shoot me an email inquiry (sales@vanpeltsales.com).
Thanks Mac VP, I will strip it a bit further, clean, and take some photos and put it all in an email. Much appreciated Steve
Try to keep the freewheel cam assembly together as you separate it and handle it. Although it’s more difficult to clean when assembled, it can be VERY difficult to reassemble the inner hub and the two springs if you let them separate from each other.
Thanks, I have sent you an email. I guess I will get to test my skills, as the photos below will show what I was doing when not on HAMB. When I was much younger I had fairly good hand skills working on F111 aircraft instrumentation. These days the eyes and finger are not as great as they were, but I am sure if I preserver I will get it back together.
MacVP, after I replied I went straight up to the shed, at least it was only 5 minutes and it is all back together. My lucky day. I can relax now and keep catching up on HAMB.
To address the question of the condition of this freewheel cam, the photos of the two parts show two things. The inner hub appears to be in pretty good condition. The “ramps” (the surface where each roller bearing moves in or out) are still pretty smooth. When they are worn badly you’ll see galling and erosion into the steel surfaces. When that happens the roller will settle into the “slot” of wear and fail to move outward fully……and that means the 12 rollers won’t move outward enough to drive the inside surface of the gear and mainshaft that they live in. The outer shell should still maintain its round shape. If it’s been bent it can create assembly and operating problems. I do see some “hammering” wear on the edges of the 12 rectangular slots for the roller bearings. I clean this wear up by running a fine tooth steel file over the edges. For folks wanting to disassemble these cam assemblies, take some photos of the unit….noting the direction of the external spring ends. When you’ve got it disassembled, look at the locations of the little holes in the hub and the outer shell. Each component will have a hole higher up than its opposite side. It must go together back the same way.
