I received my Proline trans yesterday and late last night I first took it apartthen I installed it.
Quality of construction looks great, fit and finish is nice. Clear gear set cover is nice and access opening is large and useable and the retainer tether for the plug is a nice feature.
I wanted to know what was inside and just how much fluid Proline put in to 'fill' a sealed differential, once opened I saw a beautiful gear set coated in fluid, I did 'fill' it before I closed it back up so that may be an area to check before you run yours?
If you notice the slipper spring it is very thin and it takes as much as 4 full turns or so to tighten it down completely, Proline at this point offers no info that I could find on proper slipper setting. After assembly I went from tight and backed off about 5 turns and that was too much. A couple of carpet starts signaled too much slip and some minor particle shredding of disk showed in the case. Going to start at about 4 turns backed off and closely monitor it from here today.
Oversized output bearings are impressive looking and ohhhh so smooth feeling! Nice!
Notice in the internal images of gears the index marks mid-shaft for the spider gear sets, these 'criss-crosss' each other and lock position. Small spider gears float on those shafts, each gear has a metal shim washer at the end of it. ***IMPORTANT*** observation, the side case screws that bind the two halves together were fairly loose when I removed them, the gear set turned very smoothly initially. When I put thm back together I snugged them but far from overtightened and noticed now the gears seems to be very tight, i backed off the screws and everything freed up? Hmmmm, seems to be a touchy area here and I will talk to Proline regarding this concern. I am guessing tight side to side tolerances in these cases and there must be flex that puts side pressure on the drive gears, input/idler/diff ring gears.
OK, here are images that may answer questions and at least give a nice inside look at what we have to tinker with! This thread is open for discussion, I'll share anything I find as I go along and run it. Feel free to join in and ask or comment about this Proline Transmission
And I'll sneak one in of my 2nd airbrush job on my new body! LOL
