Urgent help needed on Lotus UCR gearset

Dear all,

I’m in the process of installing the Lotus UCR gearset LOTAC05225 into the standard S1 gearbox with 3.9 final drive, but I’m now stuck halfway because the 3rd and 5th gear synchro hubs from the old gearbox do not fit onto the new driveshaft that came with the gearset.

Pictures can found over at seloc:

Does anybody here have this helical UCR gearset installed in your Exige or 340R? If so, do you recall this problem during installation?

Many thanks.

I had the UCR gearset installed by my dealer. They didn’t say anything about any problems. Sorry I can’t be of any more help

I fitted 3 gearset myself, never had any prob.
I bought the kits from quaife.
