I have acquired a DMOD Lotus Europa with a MK9 in it. I would like to check the gears out as the previous driver said it was popping out of second gear-also there seems to be no reverse. I live in Allen Park,Michigan and am willing to pay someone to give me a hand the first time as that is what was recommended I do for the first attempt. Thanks Rich Torres (cell) 313-377-9542
That car looks stinking fast. And if Bill Gendron built it, I'm sure it is fast.
To get back on topic, I agree it would be great to have someone help with the first gear change, and then afterwards you should be good to go. There are a few tricks to make it easier, and you'll pick them up quick. Hewland has manuals online. They are hany to print off beforehand to help see how all the parts go together. A few minutes of Googling will find some instructions on line, too.
Go to the hewland website and download the MK9 manual. Study that for about 30 minutes. Get your tools out and take the thing apart. If you want take pictures but if you look in the manual and look at the parts, you can do it. Poping out of gear can be worn dogs on gear or dog ring, weak detent spring on shift rod, or worn detent groove on shift rod. Take it apart and look at what you have. Have fun
Ahhh Dr. Schauf's car. Will you be running it in CenDiv Solo events?
John Carierre who is an Engineer at GM co-drove this car for a couple seasons, he lives in Ann Arbor. If you send me a PM I can get you his contact info, as he may have some insight into the car or how to get ahold of Larry Schauf.
I know Bill Gendron at Small Fortune Racing in MA did a lot of the development work on this car.
BTW- I know the DM/EM group as a Yahoo Groups discussion forum that can be helpful also on topics specific to those classes.

You will find that working on the Hewland is MUCH easier than it would be to work on the original Renault gearbox Lotus used.
I've done both by myself with no training and minimal previous gearbox experience. I am NOT a mechanic.
You may want to have Keith or Taylor (or others) freshen the rear section of the Hewland. Even if everything else is pretty sound except for gear dogs and dog rings there are some things that wear in the "back" that can be freshened or modified to improve shifting. Taylor did this for me many years ago. They only needed the rear portion of the box. However, my car had relatively few racing miles when I bought it in 1991 so it was, and is, in good shape. Given how HARD your car has been used with a LOT more power other things may be worn out.

If you're anywhere near Keith, I'd urge you to get with him so he can show you "how to." After watching once or twice, you'll understand the process. It's not really difficult, but it helps if you have small hands and long fingers. Learning how to use your hands to hold the stacks can make life much easier.
