Gearbox help needed !!!

[charri42]

Hi all,

Thanks for all your informative responses to my earlier post..

I'm in the processes of buying donor parts prior to the arrival of the starter kit..  Anyway, going to see a few gearboxes this w/end, MT75 and Type 9 (still haven't finalised choice with Westfield yet) to mate with the Zetec (hopefully 2 liter) that I haven't yet bought.

Is there anything I should check externally ? - one claims to have been reconditioned, the other only seen 40K miles.

Do I need the bellhousing from this ?? - or the bellhousing from the Zetec engines ??

As you can probably tell, I'm a first timer, so lots of head scratching !!

Also, never thought it would be so difficult to choose the colour !! - shortlisted to PO Red, Black, Yellow or the bright blue..  decisions, decisions....

Cheers all,

Chris

You have Mail

My engine cost me £175 plus £400 to recon myself a T9 box that is in the car and has done over 1000 miles cost £20 diff can be had for £25 [3.92] picking it up Monday to get the crown wheel to swap with the one in the car as it is 3.62 and LSD there are a few recomended companys to recon the diff and box Phil Stewart & Steve Parks or just risk it you pays your money....

Hi Charri

I'm faffing around with my type9 and zetec at the mo.

I've had some help from this site and others as to the best way to join'em up. Fingers crossed all should be ok during launch

Here's where I'm at.

Spigot bearing into Zetec crank (Finis 1596468)

I'm using the standard mondeo clutch and flywheel. Others like to lighten/change etc, but I'm a tight git !

My Type 9 came from a 1.8CVH Sierra donor. The box was joined to the CVH with a conveniently shaped spacer about 2mm thick to keep the crap out of the bell-housing.

The starter motor from the 1.8 CVH bolts straight on if you shave a bit of the side of the sump.

The thrust bearing I've been told is a QH133. This is slightly thicker than the 1.8CVH setup but exactly the same shape. If it works I'll let you know.

All the best

Charri,

the MT75 has an integral belhousing, the Type 9 does not.

I shouldn't worry about the condition of the box, just check there is not debris in the oil if possible.

They generally have an easier time in our cars than the sierra/granada they came from.

Thanks for your help guys (esp the detailed mail Paul). Think that clears up a few things.....

So, the bellhousing belongs to the TYpe 9 box - as opposed to the Zetec engine if that makes sense..  Hoping to get an engine with all the ancillaries - including clutch / flywheel and see how I get on. Has anybody tried running their 2.0 zetec on the standard fuel injection & ECU ?

Thought about doing this as an interim measure.. I'd have thought that without the cat, the early 2.0 zetec should improve on the standard 136ps - perhaps 145 ish ?

Cheers,

Chris

One final thought....

Are all Sierra / Granada Type 9 boxes the same ??

Do some have different ration ? - or did Ford simpy alter gearing ratios via the diff ?

Are some of the type 9's stronger (perhaps bigger engined Granadas ?)

i.e. will anything do ! - or am I better searching for a type 9 from a particular model / spec

Thanks again....

Chris.

Type 9's are stronger than MT75's (according to the chap at Ford I spoke to) and have a far greater set of ratios available from the after market specialists.

The type 9, from the 2.8i Sierra XR4 (and Capri, I think) has a slightly longer 1st than the "standard" Sierra/Granada fitment, but not by much. In a car with a 3.9 diff or shorter (4.1, 4.4 etc) 1st will be next to useless, and not much better with a 3.62. If you are stuck with a standard set of ratios, then match them to a 3.62 diff. If you plan on getting the internal ratios changed, then a 2.8 or 2.6 ratio first is available (I think) as well as longer ratios, down to 2.04 (or something like that). It depends on what diff you have as to which ratio 1st (and, sometimes 2nd) you fit.

There is lots more info on   Dave Andrews web site, which has details of most of the 'boxes and ratios available, as well as a downloadable gearing programme, which is very useful.

MT75 boxes are meant to be stronger as they generaaly came from Cosworth and 4x4 derivatives. The type 9s are not far behing and as blatman says have a larger variety of different ratios available from Qaaife / Tran X etc. They also have detachable bellhousings which mean that the original cast iron job can be swapped for a lighter aluminium job or another one to suit other than Ford engines. Some early Sierras had 4 speed type 9s which are 12kg lighter than the 5 speed, but the mounting point is approx 2" further forward. The MT75 box has an intergral bell housing and hence will only fit Ford engines. The MT75 is also fatter hence using a type 9 in  a tunnel on a chassis meant for an MT75 means that the engine / box will go futher back in the tunnel for better weight distribution. Type 9 boxes from V6 engined Sierra have a slightly longer input shaft meaning that a spacer will be needed to take up the extra distance between the gearbox and engine. These V6 boxes also have slightly taller 1st gears which is a marginal advantage, but using a non V6 box can be overcome by choosing a suitable diff ratio.
