wayno Posted September 23, 2011 Report Share Posted September 23, 2011 Did the early 521s with the J13 have a carrier bearing? I realize this is a 1970 tagged truck, but that doesn't mean it is a 1970, people move the vin plates as per needed. There is also the possibility that the carrier mount frame brace has been cut out so a one piece driveline could be used, it is hard to say what tranny is in there, is reverse all the way to the left and up(dogleg), or to the right and down? I suspect it is right and down, and is a longshaft 5 spd. Does it whine/make noise when in gear with the clutch pushed in not moving? Does it whine/make noise when in neutral with the clutch out? Do you have play/movement at the slave cyl. push rod to the clutch fork? Quote Link to comment
bustedknuckles Posted September 24, 2011 Author Report Share Posted September 24, 2011 no it is not a dog leg its a standard i wish it was a dog leg my girlfriend has one in her 79 kc that i want to steal from her... there is no play in the slave i had a new one that i threw on when i bled the clutch. it only makes the noise when in gear and it is loudest at lower rpms 5th gear is the worst. and i dont think the vin plates where changed around im the third owner of the truck the original owner had it from new and then gave it to his 16 year old daughter who blew up the l16 that was in it and then he put the l20b in there and sold it to the fella who i got it from and the guy that i got it from put the tranny in there because the original owner could figure out how to make the bracket for the tranny i will get under the truck tomorrow and take some pictures Quote Link to comment
wayno Posted September 24, 2011 Report Share Posted September 24, 2011 The slave rod needs play/movement, otherwise it has pressure against the throwout bearing which will then turn full time, if it turns full time, it will eventually start howling/vibrating and eventually it will seize. A regular 5 spd. tranny is better than a dogleg, dogleg transmissions are car trannys, they are expensive, and if used in a truck that is used as a truck, they won't last 2 years, I should know, I went threw 3 of them in 4 1/2 years. Does the whine get worse the faster you go, or the higher the engine rpms are? I use the 1985-6 shortshaft 5 spd. out of the 720 trucks with the L block tranny case, it lasted over 5 years this time, considering how I use the truck, I am styling. Quote Link to comment
bustedknuckles Posted September 24, 2011 Author Report Share Posted September 24, 2011 so i do have a little bit of play in the rod on the slave. the whine is a higher pitch the faster i go and tends to quiet a bit once i hit freeway speeds but is still there. my girlfriend just uses hers as a driver she doesnt haul anything with it thats what her turbo powerstroke is for. seeing where all of u guys live sure makes me wish i was still in vantucky i lived in orchards off of 49th for 15 years.

wayno Posted September 24, 2011 Report Share Posted September 24, 2011 Does it make noise while idling in neutral with the clutch out? If not then you should check all the u-joints and rearend fluid for color. How much play is there in the pinion shaft? Quote Link to comment
bustedknuckles Posted September 24, 2011 Author Report Share Posted September 24, 2011 no noise in neutral when idling only when in gear and driving the shaft doesnt have any pressure on the fork i am able to wiggle it around a little bit it is not excessive but enough. im not sure if i will be able to check the rear end and the ujoints out today my daughter is around and i have a couple of antique vending machines ive been restoring for a guy that i need to clear coat today. i will let u guys know after i get the time to check them out. thank you everyone for all of your help. in the world of datsuns i would be lost with out ratsun Quote Link to comment

There is a voltage regulator there also, take the old alt. that you pulled to the parts store and see if they can check it. Quote Link to comment
bustedknuckles Posted October 3, 2011 Author Report Share Posted October 3, 2011 the alt i put in is one of the internally regulated ones. same with the kind i took out Quote Link to comment
wayno Posted October 3, 2011 Report Share Posted October 3, 2011 the alt i put in is one of the internally regulated ones. same with the kind i took out The 1970 datsun 521 did not have internally regulated alternators, but they basicly look the same. This is what the plug going to the voltage regulator will look like if you install an internally regulated alternator in a 521 wiring harness, jumper wires will need to be used. You can see the digital voltage regulator behind the plugs. Quote Link to comment
Uncle Laulau Posted October 4, 2011 Report Share Posted October 4, 2011 Cool truck, I love those seats, yah I said I love your seat sssss. Retro racing look, that's what Im talking about yah. Quote Link to comment
bustedknuckles Posted October 30, 2011 Author Report Share Posted October 30, 2011 so just a little update on things ive done recently... new voltage regulator, new alternator, speedo cable, water pump, cap rotor wires plugs, and tuned the weber. i also got a floor plate and shifter boot for it put on... BUT my headlights have randomly stopped working any ideas? Quote Link to comment
skyblue Posted November 1, 2011 Report Share Posted November 1, 2011 mine was doing that too and it turned out it was a dirty fusebox terminal. wiggle the headlight fuse while the lights are on and see if that fixes it. if it does then that's probly it. if not, time to bust out the old wiring diagram.
