Crossflow/Escort Box/Clutch conundrum

[Gridgway]

It's a bit complicated, so bear with...

I have a 1600 crossflow with the Escort 4 speed (type 2?) box.  It has a clutch cover with curly fingers and this CRB Release bearing

Now the engine has been rebuilt to a 1700 and the engine builder has put a new Helix HD clutch in with straight fingers (Burton didn't have the Helix one with curly fingers in stock).  This one Clutch

This needs a different CRB with a curved face, this one CRB

Burton have said to use that bearing with a bearing carrier, this one Carrier

The trouble is that the ID of that carrier is 34mm (ish) and the nose is 30mm (as is the ID of the original bearing carrier), So that doesn;t work, and I am looking for options from the clever people of blatchat.

The obvious option is to go for a curly finger Helix clutch - but they are very much out of stock at Burton and I am pretty sure that the clutch was part of the balancing, so I don't want to change it.

I'm not sure that I could easily have a bearing carrier machined.

Is there a 34mm diameter nose for the box perhaps?

I know that the engine builder should sort it (and will do, he's a proper chap), but I'm looking for all ideas to throw in the mix.

Sorry for the length of post.  Cheers Graham

Hi Graham,

You should be able to get a carrier / adaptor to suit that cover / bearing but that doesn't look like the right one - have another word with Burton. 

Interested to know how you get on with the Helix; are you planning to use the car on track?

Try Mardi Gras Motorsport they are Helix stockists, and use the Helix crb for your cover, it's their part number 40-3259, as listed in their catalogue against an Escort Mecico Mk1

I think Graham has that CRB sorted but needs to swap the carrier as he's gone from a curly to straight finger plate. A chat with Mardi Gras may well help out with that

Thanks all.  The other plan we have is to change the gearbox nose to the 34mm (ish) one that will suite the bearing and carrier I have.  We'#ve got one tracked down, so I'll see how that goes.

I will use it on track Robert, but on road as well.  I don't think the Helix HD clutch from Burton is particularly badly behaved, but we'll find out!
