84720FourWheel Posted October 22, 2014 Author Report Share Posted October 22, 2014 So I need to replace the input shaft bearing... Do I have to pull the case apart? Quote Link to comment
datzenmike Posted October 22, 2014 Report Share Posted October 22, 2014 Five speed or trans case?? I guess either way yes. If the trans the counter bearing just below the Main input bearing gets the most wear and growls. Quote Link to comment
84720FourWheel Posted October 23, 2014 Author Report Share Posted October 23, 2014 The shaft has a bit of play, haven't heard any growling. Transmission input shaft bearing. Quote Link to comment
wayno Posted October 23, 2014 Report Share Posted October 23, 2014 I am not saying that changing the input shaft bearing is bad, but as Mike mentioned, the lower cluster gear bearing is the one that usually goes bad, I have had several of them go bad, never had an input bearing go bad. The shaft has a bit of play, haven't heard any growling. Transmission input shaft bearing. Quote Link to comment
84720FourWheel Posted October 23, 2014 Author Report Share Posted October 23, 2014 How much play would you consider acceptable? Quote Link to comment
datzenmike Posted October 23, 2014 Report Share Posted October 23, 2014 That play you feel on the shaft is normally supported by the pilot bushing in the end of the crankshaft so don't worry about it much,. It doesn't flop around like that when installed. You could replace the pilot bushing they are only $3 and 2 minutes to do if the transmission is out. Quote Link to comment

84720FourWheel Posted October 23, 2014 Author Report Share Posted October 23, 2014 That was a carb shake down trip up to Taylor Park Reservoir CO. A twin size air mattress fits perfectly between the wheel wells for camping. Had to make sure that I'd be able to make it over Vail Pass with about 800lbs of tools. Quote Link to comment
JoeCool Posted October 23, 2014 Report Share Posted October 23, 2014 That is a sweet looking truck! I fell in love with a brand new yellow 86 4x4 king cab 720 a long time ago at the Nissan dealership as a teenager before I ever had a license. Fast forward to 94 I bought a brand new black hardbody after having a steady job for two years after graduating. Quote Link to comment
84720FourWheel Posted October 23, 2014 Author Report Share Posted October 23, 2014 I pulled off the cover to take a look at the bearing. The bearing looks good, turns smoothly and the play seems to just be the shaft. So I suppose I'll replace the gasket and seal and finally put the transmission back in. Any tips to get the old gasket scraped off of the transmission? Quote Link to comment
wayno Posted October 24, 2014 Report Share Posted October 24, 2014 How many miles are on that lower cluster gear bearing? That is the weak spot on these transmissions, since it is out............. Quote Link to comment
84720FourWheel Posted October 24, 2014 Author Report Share Posted October 24, 2014 As far as I know 190k. I haven't pulled apart the tranny, just the front cover. I haven't had any noise from the transmission, so I think it should be alright. Quote Link to comment
84720FourWheel Posted November 25, 2014 Author Report Share Posted November 25, 2014 She runs! Hopefully I'll be driving her home today. I'll get some pics up tonight after work. I've been going through Datsun withdrawal. Quote Link to comment
720inOlyWa Posted November 25, 2014 Report Share Posted November 25, 2014 Congrats! I probably would have never chosen white, but now tat I see it, I love it! so clean looking, so right! I can’t wait to see your pics of it run-ready. Quote Link to comment
84720FourWheel Posted November 26, 2014 Author Report Share Posted November 26, 2014 I wanted to paint it Stainless steel silver, but it was easier to just do white. I missed it so much. I've got an exhaust leak right now because its damn hard to get the exhaust downpipe bolts tight. I replaced the gasket, so its not the lack of one. But she purrs like a kitten, and the new clutch feels amazing. I had no idea what I was missing. Tomorrow I'll get everything buttoned up and finalized. Such a huge change from the '91 Saturn SL1 I was borrowing. I'm ready to drive her for another 30 years. 1 Quote Link to comment
84720FourWheel Posted November 26, 2014 Author Report Share Posted November 26, 2014 New shift boot, will get some installed pics later. New clutch fork boot I woke up to this today Pulled in after school. It 1 Quote Link to comment
datzenmike Posted November 27, 2014 Report Share Posted November 27, 2014 That transmission picture is interesting. Usually the oil fill bung is on the left side.... usually. Another is the placement of the reverse lamp switch. It's usually just forward on that other raised boss. Driven through Minn in December before. 1 Quote Link to comment
84720FourWheel Posted November 27, 2014 Author Report Share Posted November 27, 2014 The fill plug is stuck. I add gear lube through the reverse switch hole. 1 Quote Link to comment
720inOlyWa Posted November 29, 2014 Report Share Posted November 29, 2014 I had a persistent flange gasket leak as well. I solved the leak issue by loosening the header at the head before reefing down on the flange gasket bolts themselves. Once you have the flange tightened up nicely, then tighten the exhaust header back down against the head and you should be leak free. 1 Quote Link to comment
84720FourWheel Posted January 14, 2015 Author Report Share Posted January 14, 2015 Got a new washer nozzle, its nice to not have to stop at a gas station to see out the window. Gave her a rinse to get as much of the salt off as I could. Unfortunately, rust is starting to rear its ugly head, Does anyone know where to get new bumpers for the hood? I'd like to be able to adjust the hood height. A pic of the engine sitting back in its home, with some new NGK wires. Soon this will be a clock thanks to Gradyfest The shift boot really quieted down the cab. 2 Quote Link to comment
_chiefjt Posted January 15, 2015 Report Share Posted January 15, 2015 My hood rubbers were cracked and had to break it just to get it off cause it wouldn't twist. But as many times as I went to my junkyard I found the perfect fix. Go to your local junkyard and look for a Nissan Quest. There hood rubbers are exactly the same, just gotta find a quest with some good ones. Also, if your looking for those little rubber stoppers for your gas door. The Quest is also the same. 3 Quote Link to comment

84720FourWheel Posted February 5, 2015 Author Report Share Posted February 5, 2015 I got my "new" gauge cluster. Got it torn apart and the clock out, is there any problems I'll run into pulling the old one out of my truck? Anybody done LED lighting? I want to brighten up the cluster for nighttime driving.
