Puted the things back together an made a testdrive. Grinded a little of the housing. ![](https://lh5.googleusercontent.com/-bRAK5TGPcds/T2mXxKy7BkI/AAAAAAAABKc/dl7NoswxhYU/s800/P1010276.JPG) ![](https://lh3.googleusercontent.com/-8T5B7AFamWo/T2mXxn2LzAI/AAAAAAAABKg/MC3c0eKo9cg/s800/P1010277.JPG) ![](https://lh4.googleusercontent.com/-f74ej0Mlp_c/T2mXyBF2tyI/AAAAAAAABKo/_0kfEcdtte4/s800/P1010278.JPG) RPM before modification http://www.youtube.com/watch?v=Huez4YZ7Zgo120kmh = 3500 RPM 160kmh = 4700 RPM After modification. Driving 120kmh 3200RPM http://www.youtube.com/watch?v=1N_I1Wd0-ek Driving 160kmh 4400 RPM http://www.youtube.com/watch?v=qZOTFz3bjoY About 8-9% better. I have to do the job again, because after modification a little noise is coming from the gearbox. Have to find out what the problem is. Edit: After driving 2 seasons with the car the noise is almost gone. I think the gears had to set. Herman

Nice work. Why did you have to grind off the housing? To accomodate the larger gears? Nice videos too ![Smiley](http://www.matrasport.dk/forum/Smileys/default/smiley.gif) Maybe you should find a friend to hold the camera next time...? ![Wink](http://www.matrasport.dk/forum/Smileys/default/wink.gif) I have to do the job again, because after modification a little noise is coming from the gearbox. Have to find out what the problem is.
Ouch. Well now at least you know how to do the operation and won't have to spend hours taking the trailing arm off! I hope you will be able to spot the problem. Is it gear of bearing noise? By the way: Your videos lead me to this one (Murena leading 1984 rally cross championship at Brands Hatch): http://www.youtube.com/watch?v=Ng7i5eHx0VU/Anders

There seems to be differences in gearboxes on the Murena to. Another Murena that is in the work for a modification is clearly different. Other bushing Other gears and smaller. ![](https://lh3.googleusercontent.com/-50n0wMkChsY/T2wwwT4xxOI/AAAAAAAAB9k/AuduN_VObGU/s800/P1030310.JPG) Also the fork is smaller and doesn't fit around the gearsurround. Probably a older type gearbox?? They are preparing a set of spacers and another synchoring to make it work. It is not in all cases a straight forward job, so be warned. Herman
