Iridium Lid Posted March 18, 2012 Share Posted March 18, 2012 Hi there, just wondering why there would be an adapter plate bolted between the driveshaft of my cortina and diff. The cortina has sierra 2L and 5 speed. The adapter plate is a couple of inches thick. Does this mean its not a cortina driveshaft? Which I thought would be long enough to not need anything like that. Is the sierra driveshaft a few inches shorter? ...Forgot to mention the drive shaft is a one piece Quote Link to comment Share on other sites More sharing options...
Raizer Posted March 19, 2012 Share Posted March 19, 2012 What mark Cortina? While working as a wrecker I came across a few MK1s and 2s that had a factory spacer between the shaft and diff. From memory the Sierra driveshaft is the same length as mk3/4/5 Cortinas but the center bearing is in a different spot so the shaft won't fit a Cortina.

Iridium Lid Posted March 20, 2012 Author Share Posted March 20, 2012 Interesting. Its a mk3 1976. However out of the 4 bolt holes only 2 have thread which makes me think it isnt factory ... it has fallen off on me and I'll be needing to get rid of it so I can bolt straight up to the diff.

Iridium Lid Posted March 20, 2012 Author Share Posted March 20, 2012 Wouldn't be the 5 speed sierra bringing it back a couple of inches less than the original 4 speed would it? Quote Link to comment Share on other sites More sharing options...
KKtrips Posted March 20, 2012 Share Posted March 20, 2012 Take a photo - but chances are you'll need to lengthen the driveshaft Quote Link to comment Share on other sites More sharing options...
camo_78 Posted March 20, 2012 Share Posted March 20, 2012 ive used both 4 speed cortina and auto cortina driveshafts with my seirra 5 speed,possibly you have a single piece escort driveshaft??has your mk3 got the centre bearing bolt holes about halfway along trans tunnel??if so any mk3/4 or 5 driveshaft should eliminate the need for the spacer Quote Link to comment Share on other sites More sharing options...
Raizer Posted March 20, 2012 Share Posted March 20, 2012 A lot of MK3's had 1 piece driveshafts factory, sierra box is the same length as the stock 4 speed box. Your car isn't a stock Kent engined car that's been swapped to a pinto is it? Quote Link to comment Share on other sites More sharing options...
Iridium Lid Posted March 21, 2012 Author Share Posted March 21, 2012 Nah it was definitely a 2.0. I'll get a couple of pictures up here for you guys to check out as soon as I can. Also if anyone has a mk3/4/5 driveshaft lying about theres a good chance i'll be happy to buy that. If that is gonna be my solution of course.

Iridium Lid Posted March 25, 2012 Author Share Posted March 25, 2012 Should be getting my hands on a new Trolley jack this week (finally). So watch this space Quote Link to comment Share on other sites More sharing options...
Raizer Posted March 25, 2012 Share Posted March 25, 2012 Sweet, so I have to ask why you really want to ditch the spacer? Quote Link to comment Share on other sites More sharing options...
Iridium Lid Posted March 26, 2012 Author Share Posted March 26, 2012 The reason being, it looks to have been installed poorly the first time. Only set up to accomodate 2 bolts (only 2 bolt holes have thread and those are both different). Rookie mistake not noticing this when I bought it. Drove it from Christchurch to wellington absolutely fine. Got back, was driving around not long after and those 2 poor bolts just quit on me. The bolts themselves were completely rooted. Long story short. Either way im going to be having to do somewhat minor repairs. Would just feel better cutting out the spacer while i've got a chance. Unless of course I can set that spacer up PROPERLY and it will cost me less then replacing driveshaft. But yeah, until I get under there and take some pictures etc I wont truly know what I'll be doing. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted March 26, 2012 Share Posted March 26, 2012 I think having the spacer on there is a terrible idea but you might find that all 4 bolt holes will line up if you rotate the spacer a quarter of a turn.. That said measure the length you want the driveshaft to be - measured with the car at ride height and allow for 30-40mm travel in both directions from neutral for the yoke to slip in and out of the back of the gearbox...

Iridium Lid Posted April 5, 2012 Author Share Posted April 5, 2012 Found a driveshaft for 40 bucks. But the guy says its off a cortina wagon. Can anybody tell me if this would fit a sedan?. I imagine it wouldnt. Cheers Quote Link to comment Share on other sites More sharing options...
Raizer Posted April 5, 2012 Share Posted April 5, 2012 It will if its from a pinto powered Cortina. Same floor pan and driveline. Quote Link to comment Share on other sites More sharing options...
