kevinanderson Posted July 14, 2008 Report Posted July 14, 2008 Guys- I ended up putting in a different pilot bushing in the end of the crank(larger), as the tranny wouldn't go in. It now goes in except about a 1/4 of an inch:confused: The end of the tranny spins with the with motor, as the splines are obviously meshing. But I am at a lose? Any good ideas? I hate to force it together. Of course this has caused some heated discussion between my father and me(and the heat and trouble light that shines everywhere except where you want it, and the wrench you threw and now have to crawl back out and get........ ) Quote
kevinanderson Posted July 15, 2008 Author Report Posted July 15, 2008 Gosh, noone have 2 cents for this? Quote
Normspeed Posted July 15, 2008 Report Posted July 15, 2008 I might have missed the earlier part. Is this a trans where you have swapped out the front shaft from another trans? Or changed from fluid drive to 3 speed? I'd hate to give you wrong advice. Mine is a factory OD, 3 speed. I've had trouble on occasion getting the trans to fully go in against the bellhousing, especially with a brand new pilot bushing. I used a couple longer bolts and carefully pulled the trans into place and all was good. But that's in a setup where I was sure the input shaft was the right length for the setup because it was factory stuff. Quote
james curl Posted July 15, 2008 Report Posted July 15, 2008 You could pull the transmission, pressure plate and clutch disc. Re-install the transmission and using a flashlight through the two vent holes or from underneath looking at the relationship of the input shaft and the pilot bearing. If the transmission is still 1/4" out you should be able to see what would happen if you forced it all the way in using the four mounting bolts. Quote
kevinanderson Posted July 15, 2008 Author Report Posted July 15, 2008 Great idea, James. I never thought of thought.......... And Normspeed- i thought of drawing it up, but what if. I'm swapping a OD from a '54 into my straight stick '48. I knew there was help somewhere.... thanks guys. Quote
James_Douglas Posted July 15, 2008 Report Posted July 15, 2008 Thinking ahead a couple of steps...If you need to get a busing out... Get a wood-screw stud. The kind that has a wood screw on one end and a machine screw on the other. Get one that the machine screw side will screw into the end of a slide hammer (use a coupling nut). The screw the thing into the bushing until it bites and side hammer it out. I had one years ago that was bitch to get out and an old timer showed me this way to do it. I would do what norm said AFTER removing the bushing. When the trans is in place and the tip is sticking into the crankshaft, use a black marker and mark trans shaft where it enters the crankshaft flange. When you pull it out, you can then measure the depth of the hole in the crankshaft and can calculate the exact max bushing length. Best, James Quote
james curl Posted July 16, 2008 Report Posted July 16, 2008 You should be able to pack the bushing and the chamber in the crankshaft with wheel bearing grease. Then using wooden dowel or a tight fitting bolt inserted into the end of the bushing hit the dowel or bolt with a three-pound hammer. The bushing should hydraulic out of the crankshaft. Quote
kevinanderson Posted July 16, 2008 Author Report Posted July 16, 2008 Good ideas, Gents. But my Dad was a Diesel mechanic for almost 40 years. He has stuff I have no clue what it is used for. Had a bushing puller that put light threads into the bushing and a 3 fingered slide hammer the goes onto the bushing and catches the shoulder. I am almost 50 and have worked beside him most of them-and I had never seen either one. Quote
Normspeed Posted July 16, 2008 Report Posted July 16, 2008 The Jamses are right, probably the best route would be to yank the trans back out, especially if your pilot bushing was an extremely snug test fit on the transmission shaft. I think the actual transmissions are pretty similar (I recently ran a P15 trans in place of my 53 overdrive trans for several months) If you took the trans back out you could closely compare both shafts. When I pulled mine back up with bolts, believe me I was not cranking down hard. Only very minimal pressure on the wrench. I tightened the bolts 1/2 turn each, then pushed the trans a bit, then another 1/2 turn and so on and it pulled up snug pretty easily. Trans was on a trans jack too. Quote
kevinanderson Posted July 16, 2008 Author Report Posted July 16, 2008 Well boys, it's in. That front housing on the input shaft was snug. A little snugging here and there and in it went. Whew! Thanks guys. Quote
Normspeed Posted July 16, 2008 Report Posted July 16, 2008 Kevin, one other thing...The shift arms on the 53 trans may be a little different than the earlier ones. You may need to either put the Dodge shifter arms on the new trans, or be ready to make some length adjustments to the shift linkage. Quote
kevinanderson Posted July 16, 2008 Author Report Posted July 16, 2008 ok. well watch for this. thank-you Quote
eric wissing Posted July 17, 2008 Report Posted July 17, 2008 Kevin, cool. The OD is a great add on. Whay more people din't order the option is a mystery to me. I guess people weren't traveling that far. You have to Post A Pic for everyone. Eric Quote
