Differences with speedometer cables

[CRSMP5]

84 jetta is clip on... german started in 82 w clip on... westy bunny thru 84 is screw on... 85+ all clip on..

gas jetta different then diesel too... erg/oxs box....  so if you have screw on.. look for westy bunny, 81-84... diesel better the gas.. but neither have egr/oxs box...

 could have sworn i posted this before...

could have sworn i posted this before...

I deleted our banter as it had no relevance to this for sale thread haha. I have an 84 Jetta that was gas, it is a screw on for sure.

then its a 80 or 81 speedo head... 79 and older the facia is round vs square... dashers had those.. then dasher/jetta in 80, dasher, cabby, jetta in 81.. and 82 rocco/jetta/cabby/quantium went to clip.. also starts the magnetic pick up area being milled out for factory cruise too..

so trust me when i say stock was clip in 84.. but westy speedo cables easier to find as 100% of those will solve your need... diesel vs gas westy cable differs in how the pin goes into the speedo head... the pin is rubber mounted on diesel.. gas is not.. pin tends to be plastic on diesel.. it pulls out of the rubber coupler..

I have three mk1's in my driveway all with screw-on speedo cables.

All German built (obviously as all mk1 Jetta's were), one is a 1981 1.6D, the other two are 1984 1.7 EN gas cars. All three were screw in, all three with factory installed clusters.

I think you are mixing Rabbit facts in with Jetta facts. All mk1 jetta's (1980-1984) are all the same dash wise.

kilo or mph??

the shape of cluster yes... but 80, 81 is pre shift light.. 82-88ish, then ce2 cabby... the pcb is different for all 3... the pre shift light has room to add boost gauge the rest lack..

dasher 78-79 same shape, but speedo/clock round tins vs square..

when shiftlight came out, euro also got maf and eco gauges that uses the magnetic speed pickup like vw cruise does.. so they milled the pickup area out... ad wet to clip vs screw on cable...

now kilo speedo... educate me...

Just in the process of removing my auto trans from my 84 Jetta and was looking at the speedo cable. Looks like the trans. end of the cable has a big nut - but also looks like there is small steel clip. Nut didn't want to turn, removing clip just allowed the gear assembly to turn. So I left it for a beer or 3.

So what do I have?  As I don't want to start breaking stuff. Any pics?

thanks

well what speedo you got??

if you took the "tab" off then lift straight up on the gear/big niut.. holds it in... just the o-ring dry so hard to pull up..

yours gas or diesel?? egr box in speedo cable will determin how or what piece of cable you gotta get..

now kilo speedo... educate me...

The two 84s' are kilo, the 81 miles. All screw on.

[CRSMP5]

81 supposed to be screw on... kilo.. well thats interesting... the fact they have a brass gear vs plastic i thoought they were odd... just never cought on why i never used the kilo cluster i have tucked away for 13+ years... that would be why...

brass vs the plastic break and quit counting distance gear.. fyi.. wrong diameter to try to retro fit...

[RabbitJockey]

maybe all the canadian stuff is different

[8v-of-fury]

I've had several break. A good glob of JB weld all over everything mates the gear to the shaft for life lol.

IIRC, the MotoMeter clusters had the brass gear. The VDO had the plastic gear.
