Turns out my "spare" saginaw in the garage is a 4-spd... hell, thats too good for my new parts-hauler, I needa save that one for the "someday" t-bucket... So, do ya think this 3-spd is rebuildable? My main bearing and holder: Some bozo didnt put lock***e on the mains-holder bolts, and it all fed itself to the clutch, which seems fine, miraculously. Realistically, I should just go to a junkyard and pull another... but thats such a PITA! What should getting this one rebuilt run me? Theres a lot of play in the output shaft, too. Thanks, Jason
And yes, the synchros were non-existant the one lap around the block I gave it... Thats what double-clutching is for!
standard proceedure is to take the trans completely apart, clean up and inspect the parts, and then you'll know what you need to replace, which will give you an idea of how much it will cost to fix. Looks like it mostly just lost the front bearing, but the pieces could have chewed up other parts that we can't see in the pics.
Did it this way when I rebuilt my 3-sp saginaw box for my T project...I guess we'll see how she does when I get it slapped in...one day! heheh
Some round track will pay loads for that 3 speed unit.. 3 lines on input shaft 3.50 low and 1.89 second. the most common saginaw is no lines which is a 2.85 low and a 1.68 second. ... Bobby...
I got a pair of those gearboxes I just picked up from a swap meet for 20 bucks each...I never knew the gearing difference, that's interesting...if you're in desperate need of parts let me know and I might be able to strip one of them down for ya...
burndup: I'd seriously think about tearing it down and rebuilding it yourself. they are about as simple as ******s get, you don't need much in the way of tools, some good external snapring pliers (snap on SRP1A are the ones I use, don't quote me on the part no. I can check if you want), and a dowel or rod machined a couple thou' under the diameter of the counter gear shaft to support the hand packed bearings during re***embly are about all you need. I built these boxes for my IMCA modified and I did a few for fellow racers as well, with 1st gear removes and I'd lighten second gear. I keep telling myself that next time I do a sag or a muncie I'm going to take some pics and post some tech. Anyhow, they are really nothing to be affraid of, you can find good info in older haynes and chiltons books. PM me if you need any help.
PBR, where's a good place to order new parts? I've got two lathes, a mill, two presses, and at least one pair of snapring pliers, I'd like to attempt it! Thanks, J
End of output shaft is bushed and supported by the U-joint, I believe--play is just because the joint is out. If you just need bearings and synchro rings, all will be easy and fairly cheap. If you need gears, I'd guess that any new single gear will cost lots more than a whole used trans from the junkyard.
