Ra40 w50 to w57 conversion?

[maurice c]

HI guys,
I need to change over my gearbox soon as the bearings are squealing quiet badly in second and fourth when decelerating. I've got a 40 with a rg and w50. I've got hold of a w57 with a 22r belhousing that was already fitted to a rg so i'm confident that it will fit ok. The questions that I have are, has anybody already fitted a w57 in a 40? (I'm sure they have). if so what shifter postion have they used and what thruss bearing and slave cylinder have they used? I have searched for this but cant get any info.
Heres a picture of the w50 in teh car, the car used to be an automatic and the gearbox is from a manual ra40 that I though was pretty standard.

It looks pretty far back but seems to line up with the edge of the dust cover for the driveshaft, please excuse shite photo, it was starting to get dark.
Heres the box i'm putting in, its from a ra65 i think.

I think that its about 45 mm more forward. Has anybody used this shifter position? If so is it too close to the dashboard? Thanks maurice.

If you can get a shifter positioner from and MA70 it will put the shifter in the same position.

Thrust bearing and slave cylinder that you want are from an RT142 Corona or RA65 Celica. Spigot bearing remains unchanged from the W50 item. As mentioned, the shifter position can be changed, you want it as far back as possible, and as short as possible. Although the W50 item from an RA40 fits, the later shifters are shorter and much better to use.

The W50 shifter is not compatible with a W5x box.
The 'ball' is about 2mm bigger.
While technically it does fit, it doesn't fit properly and doesn't engage easily.

[o_man_ra23]

Umm... beg to differ. There were 2 different W50 shifters, the early pre-RA40 items and the RA40 on items. The RA40 on items had the same ball, and same bush (part number the same) engaging. The early items had the larger ball, and no bush, and do not fit properly as you suggested. Found all this out not long ago when I had a pre-RA40 W50, RA40 W50 and RT142 W5x all in my carport at the same time and was sorting out bushes. Ended up using the good secondhand bush from the W5x in the RA40 W50 and the new bush I bought for the W50 for the W5x... and the ol pre-RA40 W50 wouldn't fit a bush over the ball.

[CrUZida]

Which ball are you talking about ?
The one at the bottom (white bush) or the one in the middle ('green' bush) ?

[o_man_ra23]

White bush at the bottom... didn't compare the middle ball as I didn't change them over (though I still do have the pre-RA40 gear lever in the shed)

[CrUZida]

Yeah, I'm talking about the middle ball.
The W50 shifter I compared had a middle ball that was 2mm bigger than the W5x shifter.

Wilbo found the same thing when he compared his.

Hmm... might have to find an RA40 to compare balls with...

[maurice c]

Well the thrust bearing seems to be the same according to the exedy catalogue.

The thrust bearing may be the same (depending on what thrust bearing carrier you use) but the thrust bearing carrier is different. As is the fork. And the slave cyl.

[maurice c]

The carriers may be the same as well, I have an old w50 from a 23 in the shed and I remember that the fork is completely different on the 23/28 to the 40. The 23/28 looks a lot stronger as does the bell housing. I'm guesstimateing that the carrier and retaining pins are the same. So far I havent heard from anybody that has one in their 40 yet, i'll have to post a bit of a how to when i get the chance. Ironically, i've actually got this gearbox from Mitch from the CCG. As we all know he is a notorious 40 Hater. I'm guessing that he hasnt realised that the gearbox is going in a 40. If he could just get over the 40 problem he would be a top bloke.

[CrUZida]

If the fork is the same then chances are the carrier will be the same too.

I know the fork in my old W50 was different to what I've used for the W5x range.

NIce one Maurice, now lets all gang up on Mitch.
