Bellhousing bulge
James - 1/10/03 at 11:57 AM

Just curious really:

On the Type9 bellhousing there's a cylindrical bulge on the side that leads away from the starter motor. What is it for?
I'm not intending to bother but if it's unnecessary has anyone chopped it off and replaced with a plate over the hole?

I realise there maybe strength issues but if Hicost has managed to get away with chopping two holes in his bellhousing and have 415+BHP I think it'd cope with a Pinto!

Cheers,

James

slightly related (well, sort of...)

I thought i'd cut the back mounting lug off my sierra irs dif, only to find the casting goes up and in where the bolts go, so now i need to swap backplates over with my spare one as it has a hole in it!

ooops...

I think it's meant to provide space for the drive gear on an inertia starter motor - it sits in that space until it's pulled back onto the flywheel when the starter spins.

Strange, 'cos the Pinto uses a pre-engaged starter, doesn't it?

If inertia starter motor is the type where the gear jumps backward*** on a solenoid then you're correct- the Pinto does not have one of these. Or, atleast, my '205' injection one doesn't!
Maybe the older engines with Type9's did't have pre-engaged and it was cheaper to use the same bell-housing mould than to cast new ones???

Thinking about it though- the part of the bellhousing I'm refering to is about 7-8" long! Seems a little excessive for a small gear on a rod!

James,

Are you serious that the Hicost mibile has 415 Bhp?!

Holy sheeeet that must be like poo of a teflon shovel.

Have you been in it?

I went in a Blackbird Formula 27 last night, my first taste of bikedom, that was fast. Wouldnt be a patch in Hicosts thoug if its pumping out 415.

Of course I have!

And a fantastic bit of kit it is too.

It's atleast 415BHP possibly more. I think he's got some old dyno printouts in his photo archive?
Bear in mind there was a large NOS bottle strapped behind the passenger aswell for those times when 415BHP just wasn't enough! That's gone now- I think it was boring beating Mr Schumacher off the line!

the type 9 box was an evolution of the earlier 4 speed box as fitted to the cortina granada type which in the early days had inertia types starters.

slightly more on topic with this question,

I have a cranky old 4 speed at the moment, does a more modern 5 speed have the same dimension from the bell housing / Gear box joint to point where the gear stick comes out? I want to fir a 5 speed at some point and dont really want to have to hut different holes for the gear stick.

Also is the measurement from the aforementioned g/b and B/h joint to the mounting bolt hole the same on both boxes?

Possibly....but depends on the type of four speed box fitted (of which there are many choices)
