G5M01 Gearbox into BG Astina
Hey Everyone.
I have acquired a gearbox and put it into my BG astina, at the time not realizing what the exact differences were. turns out it is 28 spline on the gearbox, as opposed to my old gearbox of 26 spline. what are my options in driveshafts and the joint shaft(dummy shaft/lay shaft) i have worked out that the original BG passenger side shaft could be used, all i would need is a 28 spline inner cv joint attached onto to it. what can be done for the correct lengths of the driver side shafts? i have grabbed a BA Astina joint shaft(dummy shaft/lay shaft) think out of a v6 from UPI and it was 28 spline, but too long, I also have a 626 joint shaft(dummy shaft/lay shaft) which is the exact same size of the BA one. were the BA 4cyl shafts that came with these boxes the same size as the BG joint shaft(dummy shaft/lay shaft) or do i have to get one made up? if i do have to get these shafts made up, where can this be done? Im having a spot of difficulties here in SA with OG Driveshafts, and Adelaide CV. any help would be appreciated. Cheers Team. Sam.

you can use your current driveshafts if you switch the inner cups to ba versions and the layshaft from ba.

No-ones really sure about the Lynx switching Gearboxes because they sold so badly that there were 1994 built cars sold/complianced in 1996 etc They sat in holding yards for years apparently. With a $35K+ Onroads price its no wonder they did. It was nearly a $15K premium over the "base" Lasers.

wow thanks so much for that information!
i have found a place in adel with 2 gearboxes, but won separate the gearbox from the layshaft for whatever reason, and another place that has a lynx with the shaft, i'm hoping that its the right 28 spline one, because even though they sold badly, there would still be possibilities of the 24 floating around. I look at the AADI driveshaft book, all the kj's and Ba's are 24, while in a&f driveshafts, there is a clear mention of this switch over, hence the queries. appreciate the feedback guys!! Top stuff!

so ascertain what gearbox it is, g or f. doesn't matter what the sahfts are then as they match the gearboxes.

its a little hard when dealing with these "mechanics"... u give all the information you can, and they still dont wanna comply... oh we'll only remove the gearbox if we are sure you are going to buy it... :/ ... im only gonna spend my casholah with you if you can guarantee thats its what i want... only takes 30 mins to make sure its the right shaft...
hopefully Christies Beach auto wreckers are helpful

it actually takes about 10 seconds to open the bonnet and look at the top of the gearbox. as i said earlier, the shafts match the gearbox.

ctrl+f "lynx" ... and you'll find that it makes a huge mention on the kj2 models... and on another note, when informing the wrecking yard owners of the g series number on the gearbox, how would i describe the location of the box when i'm on the phone to them?

reading the mazda stuff looks like it is 28/24 spline but the lynx is 28/28 that's why they said no other kj shaft will fit a lynx, interesting read.

Yeah the Kia "G-Series is meant to be tough, I suspect it's actually a 626 (2.2L non-Turbo) G-Series internals in the BP G-series casing (which is a valid swap that's documented on FordLaser.com).
Lynx stuff does turn up there's one being parted out on eBay at the moment, Repco claim to do Lynx shafts, I'll try to cross-check to see if they're listing a Kia shaft or if they're just listing KJ shafts...

Scratch the Repco idea, their catalog lists a Lynx as using a KF/KH 1.8 DOHC shaft. And describes them as 26 splines.
A GH 626 shaft may be 28 spline with matching diameter etc though (based on the http://www.repcotrade.com.au/files/d...tCatalogue.pdf)

Oh the Ford wreckers in Athol Park had a Lynx or two when I was there last. Maybe they can sort you out?
