Bit like it say's on the tin really.

After hours of exhaustive searching on the tinternet, I'm stumped for a solution.

Finally got the engine running to a point where I was happy to drive the car under its own power (yay!) threw the car in reverse and clunk clunk clunk.

From what I can gather my prop shaft is about 20mm too short and when in reverse the splines of the gearbox are not quite engaging on the prop. The best solution I guess is to get a new prop shaft made up, but for the mean time I was wondering were to get hold of a spacer. I saw one on ebay for sale not too long ago, so it must be possible.

Any ideas?

Cheers

What gearbox is fitted?

The splines don't move in relation to the prop. They are engaged as soon as the prop nose enters the gearbox tailshaft whether you are in forward or reverse gear. With a live axle you need some leeway on the amount of prop in the gearbox to allow for movement of the axle. It sounds more like a gearbox problem than propshaft.

Tunnel and prop angle

looking at your pic pete, my shaft () is in no way, shape or form, as far in as yours! will take a pic today whilst at work

Its an old mk2 escort box with the gear lever that screws down (no idea of mk number)

Sounds to me like you probably need more than 20mm. You want as much of the splined section engaged as possible whilst leaving enough clearance so that it doesn't bottom out when the axles moves around.

Bit of a bodge and definatly not safe for use but to get you rolling what about extending your present prop? If you can find a prop with the same internal diameter as your present outside diameter could cut and sleeve it until your happy with the length. Then you have a pattern to get new one made up. Bailey Morris are just down the A1 at Eaton Socon near St Neots.

Right, took some pics, looks like a trip to the spare prop man....

I'm sure that is very dangerous. I reckon it will launch itself if you try to use it at high speed.
For the sake of your legs I would get a new prop. MK Sportcars will make one for you at a good price.

I would hazard a guess that the prop was designed for a type 9, but a 4 speed escort box is fitted

Thats my thinking, need to take some measurements and get me a new one. Gutted! Just got the engine running right!

That was my next post. There's five granada's and one auto sierra sat outside the club at the mo. Is the type 9 fitted to the Granada and if so is it a straight swap? Will do some searching about it too.

Many thanks

Right, been searching for hours and I've found out that the gearbox is a mt75 (bloke wants a pint of lager and 2 packets of crisps).

My big question is, can I fit the mt75 into my bog standard book chassis without any mods? Been looking though hundreds of posts and still none the wiser. I gather the engine and gearbox will just slide together, but do I need to change the clutch from the standard xflow one? It's all bloody confusing!!!

The MT75 is a lot bigger in the bellhousing area and tailshaft is different, a type 9 prop would not fit it as it uses a flange and donut type output instead of the splines .I also think that the 4 speed output shaft is smaller than a type 9 so your drive shaft may not fit a type 9 either.
You could always move the engine mounts, or remake them if you have enough space around the bell housing to move the engine back this may be your best option .
