    Reverse switch for 71B 5-speed

    Very helpful. Turns out a fuse had blown which explains the lack of reverse lights when the switch was bypassed. Your photo and explanation help me better understand the problem. Am I right in thinking that the pin is dropping into the notch (and thus, not extending to break continuity)? if so, what might cause that situation? The plunger moves relatively freely and has consistent spring tension pushing it outward. There is minor scraping when moving, but nothing that seems restrictive to movement. Perhaps my next step thould be to remove the switch, insert a thin rod into the switch hole, and the feel what happens as the truck is shifter in and out of reverse? (Ignition off, of course) That might add some info, but won’t give me reverse lights.... Better ideas?

    Reverse switch for 71B 5-speed

    No other switches present. I pulled the switch to check function. Plunger extended = no continuity Plunger depressed = continuity while under, I tried directly connecting the truck’s reverse wired together (removing the switch from the circuit). No reverse lights. Because the truck was an automatic, there are two wires that were attached to the old internal neutral switch. These two wires are now connected together. If not connected together, the truck won’t turn over. i ended up just disconnecting the switch so there would be CONTANTLY ON” no reverse lights. So what seems to be occurring is: when the switch is in place ... the plunger remains depressed regardless of gear selection, or even neutral. If so, that is problem #1 Problem #2 then would be why wouldn’t the reverse lights just stay on if the switch is bypassed? is there a lost ground connection with the switch out? Or? i wish this was as simple as having the wrong type of switch installed. ideas?

    Reverse switch for 71B 5-speed

    After switching an automatic to a 5 speed, my reverse lights are always on. From this thread, I’d assume that I need to replace the switch. If so, for what specifically am I searching? Or could the leads just be reversed.? (‘78 620) can I scavenge the switch from the automatic to use with the 280z 5 speed?

    1974 Datsun 620 Wiper Switch Options

    Any options for adding intermittent wiper option? I’ve considered adding a momentary switch to get a single swipe but this seems awkward. (‘78 620)

    Need help identifying dogleg five-speed in my '69

    As always, very. Valuable information. Are these considered good transmissions in terms of -street/hwy driving -repairability ?

    5 Speed for L16

    Help. Which manual transmission(s) will fit a ‘78 620 kc (L20b)? If more than one, which is best for regular driving? F4W71B? F5W71B? Thanks

    Weber 32/36 choke problems

    Jumping on this thread with a choke adjustment question: my L20b (automatic) with a Weber starts right up and the fast idle keeps it going. But, when the fast idle cuts out due to my touching the gas pedal, rhe truck’s idle drops and almost almost stalls. Then after a few minutes more warming up while driving, it rises to a decent 900ish (in gear). I have a feeling that the choke is opening too soon. Inspecting the choke when cold shows me that it is almost closed (as suggested in the literature). Would rotating it help this problem?as it is now , I almost drive it like a manual by slipping it into neutral ,to keep the rpms up until it is sufficiently warm to avoid stalling. BTW, fuel lines are clear, air filter is clean (though not oiled), valves appropriately adjusted, timing seems correct, battery is strong, etc ideas..? j u

    620 front suspension and steering

    What is the original turn radius for these? I may already be there.

    620 front suspension and steering

    I’d like to improve the turning radius of my ‘78 620. Besides cleaning and adjusting the stock box, anything practical to be done?

    620 A/C compressor mount

    I have read a lot of old posts about the difficulties of adding A/C to a l20b 620 truck, but I want to give it a shot. I understand that the appropriate compressor bracket is very hard to come by. If no one has one available, does anyone know of a type that can be modified? Or, even a picture of what a picture or diagram with measurements from which I could fabricate one? I’m assuming it is critical to anchor to the compressor to the engine rather than the frame to avoid mismatched torsion across the belt. Other ideas? Thanks

    Z20 and L20B Interchangibility

    Thanks, Datzenmike! You are a veritable wealth of knowledge.

    Z20 and L20B Interchangibility

    I came across a 1980 200sx with a z20 and 5 speed transmission. Could the entire power train replace the power train in a 620 kc (currently automatic)? If so, how difficult a swap is it and what benefits (besides getting a 5 speed tranny, which I would prefer to an automatic) and losses would this involve. Also, could I ever hope to pass a California smog test?

    Sliding Rear Window - Help!?

    Okay.... Do the sliding windows require a special gasket or do they fit into the regular rear window gasket?

    Moving to Cali.....smog Q's

    I would imagine that a class action lawsuit could be filed against CA based upon impedance of interstate commerce. Putting smog equipment on a vehicle that wasn't originally equipped —especially a vintage vehicle— is onerous. Requiring new residents to either buy a different car or else go through junkyard gymnastics isn’t reasonable. At minimum, there should be one of the following: —incremental changes to later years in the cars that no longer require a smog test —a reasonable pollution abatement fee for non compliant older vehicles —a dollar limit to the expenses incurred in pursuit of the vehicles YOM standard —allowance for newer technology/equipment swapping that would allow DDs to be used on the roads. The fee for non-compliance is really nothing different from what industry is allowed to do. They can even buy carbon credits.

    Sliding Rear Window - Help!?

    Bump....well, would rear windows from a 720 king cab fit in a 1978 620 king cab? All I ever see lister are for years 1980 and on. I’ve seen earlier trucks with sliders, but information is isn’t forthcoming. Lawrence makes a slider but they are not responsive about templates, dimensions, etc. thanks
  23. I recently purchased a 1978 620 pickup (L20b with automatic). It was running quite roughly and barely idling. Going through it I discovered and corrected: -spark plug. Cables for cylinders 2 and 3 were switched. - plugs for # 1: 2, and 4 looked clean but #2 was gunked up. - no response on the idle screw. (Because the car had been sitting for months, the apparent fouling of the idle circuit, and that the hitachi carb was a federal model rather than a California version, I replaced the carb itch a professionally rebuilt one) -electric fuel pump receiving power and seeming to function -gas filter clean -leaky distributor vacuum advance tube -distributor fine adjustment range all the way to the left, i.e. the distributor at counterclockwise extreme -timing mark at tic mark at mild rev., with no apparent way to advance it. -distributor rotor has appropriate play and spring-back -vacuum advance occurs when tube is sucked -new battery -good ground connections -air cleaner clean -fresh gas -Pulling cables from plug 2 or 3 does NOT stall the engine Nevertheless it continues to: idle roughly until warmed up Stumble when reved while in Park Poor running in gear with very weak idle....often stalling. What am I missing here? The timing seems off but I am unable to adequately adjust the distributor. Thank you
  24. Whoa! I just put in a Weber 32/36. What a difference. No srumbles, no hesitations, no roughness. Good bye, Hitachi! so, I suppose next is the head change and cam.
