Fitting propshaft
locoboy - 17/9/06 at 10:05 AM

I got my MK prop yesterday and have a bit of a problem on my hands now fitting it to my GTS

The rear flange on the prop that butts up to the diff it too wide to pass through the tunnel from front to back, as is the centre bearing (2 piece BEC shaft).

Removing the diff and putting the shaft in from back to front would not work either because the centre bearing is too wide for the tunnel.

Can the rear UJ on a sierra shaft be dismantled and re assembled in the tunnel?

thanks

I take it you have your engine installed. We were able to remove and replace the complete propshaft from underneath and on the offside, although this was on an MK not a GTS.

The propshaft can be split in half at the centre UJ and installed in two pieces and bolted back together in the tunnel.

Cheers Phil.

Yep eingine is in, but even wth the engine out i could not slide the flange from front to back in the tunnel.

I can see where it unbolts but what i need to do is to take the rear flange off the prop, fit the prop in the tunnel then re-fit the flange.

Can this be take off and re fitted?

No, the rear flange that mounts to the diff cannot be removed. Have you tried installing it with the flange at an angle?

How have others done it?

again not a GTS, but to get mine into the locost, i took the tunnel cover off, went in through the top heading forwards, dipped under the engine, theh dropped the back end in and pulled it back, up to the diff.

Yep,

tried it on the wee and it doesnt have the angle to clear the tunnel side rails.

The gap in the tunnel is 100mm and the prop flange IIRC is 109mm.

Its close when its on the slant but not close enough!

It must go. How have others managed to get the propshaft in?

If the Diff flange it bolts to goes into the Tunnel then the prop flange must also fit up the tunnel?

Can you take the Diff out and push it up/through into the tunnel?

Unfortunately not

Im thinking the only way to do this is to split the prop at the centre bearing (leaving the bearing on the front section) then remove the diff and slide the back section in from the diff end.

What a bloody ball ache just to fit the prop

any other ideas?

The flange will fit up the tunnel. Its a tight fit, and t needs to be at an angle and the prop wiggled about to get it in. Its easier with 2 people.

Is this the tunnel that also houses 2 petrol pipes, a brake pipe and a wiring loom ?

How does that work ?

I would much rather run the above inside where not exposed to road crud, but nobody seems to do this - or do they ?

The tunnel is enclosed on pretty much every car ive seen as the floor covers the entire width of the car.
