Growly gearbox

Post by DARK STAR » Sat Jun 23, 2018 4:50 pm

Posting (again) in the Middlebridge section because I have a type 9 gearbox in the Coupé.
However, it is not a normal type 9, I broke that first time out at Harewood :roll:
It is an RS spec box which is supposed to be able to handle 500 bhp, so presumably reinforced a bit here and there.

The problem is apparently the input shaft bearing which is making very ominous noises.
It seems worse in neutral but that's probably because the engine makes so much noise when in gear :wink:
Two questions, first, if I keep using the car will I do any terminal damage to the box (or anything else) ?
And is the bearing in question a standard one or do I need to ask Mr Ford for his R$ catalogue ?

Burton's have normal ones in stock, but they don't mention 2,9 engines in the applications ...

Odd as I can’t think of a single RS vehicle that uses a type 9 gearbox. Likewise, if yours is supposed to be safe to 500bhp then that’s about twice what BGH can make them safe to - and they’re pretty much “the” gurus fit the type 9.
I think someone managed to pull a fast one on you there, Chris..as the only RS-spec 2WD RWD 5 speed gearbox is the Borg Warner T5.

The type 9 was used behind a 2.9i in a few Granadas but I’m pretty sure it was the “V6” version with the bigger layshaft bearing.

Hmm ok thanks Phil.
It was probably me who misunderstood what was said or forgotten over 25 years :roll:
It certainly looks like a type 9 gearbox, so presumably a "V6" Granada version.
Seems strong enough in general and very sweet to use with the Quickshift.

So, is the input shaft bearing standard? (if I am I right in thinking this is the problem)
And will using the car damage anything in the meantime?

XR (as in XR4i) or V6 spec at a guess.

The type 9 can tend to grumble for years before throwing in the towel.

If it is the layshaft bearings, it will be quieter (normally) in 4th and 5th gear but in standard spec was just about strong enough for the standard 2.8/2.9 V6.

The pic looks like what I’d call a “spigot” bearing which goes in the end of the crank - I’m assuming that’s what we are referring to? In which case, when they fail, they’ll take the main gearbox input shaft bearing with it as the first motion shaft is then unsupported. MikeyBikey is the king of gearbox destruction and seems to kill them with regularity (although the Essex one is different in looks, it does the same job).

I would be tempted to do a exchange gbox with BGH, they will not pull their punches about the type 9s limitations.

My experience is the same as Phil’s, noisey boxes seem to keep going ok, for awhile.. until they go bang :w

I got one off Don Ross, he used it for a few years in his triple carbed sprint 5a.

I used it on my sprinting 5a behind a 200bhp 2.9 12v ok too.

Later that engine and box was fitted to a MB (400-500kg more weight) and used for some towing, it didn’t last long!

Your light weight Coupe on road tyres shouldn’t give its gbox too much trouble.

The only way of telling if it’s the later “uprated” box is to look at the front when it’s removed - the plate with the blue bolts shows it has the extra bearing.

"Extra bearing"? I'm curious. Are you saying some Type 9 gearboxes have an additional bearing? If so what does it support and why?
Thanks

Excellent article Roger.
Though it mentions the 2.8 engine it is silent on the 2.9 so my questions are:-
(1) Is the uprated "extra" bearing a Ford improvement or is it purely an after-market thing?
(2) If Ford, then do the Type 9 'boxes that Middlebridge used with the 2.9 engine have the uprated "extra" bearing?

It’s a Ford modification.
