crash gear box changing gear

[Ganmain Tony]

I must confess to not posting as I was hoping for another (and more embarassing) bit of film of someone doing worse gear changes than your's truly.

Alas it has not eventuated, or in any case, it may not have been humanly possible.

Well done on getting it sorted..

Do you have a picture you could post of your throttle return spring setup?

Bit rude I know, having not helped, then asking for it... but I am from West Island.

Hi Tony

I had some fun this week doing road test on my Pattern 12, with the Go Pro mounted. Been trying to get camera angle right to show clutch, gas, pedal, lever and view of the road.

Now I'm trying to figure how to down load the video to YouTub.

One thing is very certain as a cause of gear crunch, any clutch drag at all. My Pat 12 Chevy had a problem in that the surface of the clutch was sticky and that really screwed the shifts unless you got a perfect match on speeds. With a new really clean clutch it shifts like a dream. Only real crunches are going down from 3rd to 2nd.

Will work on the video.

Cheers Phil

Have had quite a lot of practice lately, as my F15A is back on the road after many years in storage. I did not have any previous experience driving non-synchromesh gearboxes before driving my CMP. Apart from the theory I have had very little guidance, so it's just a matter of practice.

What I learned till now is that the engine idle settings have to be right, too high and you'll grind when shifting. Also, take your time between shifts. If you try to shift too quickly, you'll grind the gears. Shifting up can be learned quickly, shifting down is more difficult. Here I find that the engine revs need to be much lower than expected. This is all due to being accustomed to synchromesh gearboxes which can shift very quickly of course.

Another point is that I find the pedal setup ideal, with the throttle pedal in the middle and lower than the brake pedal, it is very easy to use your heel to blip the throttle during downshift.

I have been reading this thread with great interest as there are some very good pointers which I will try out. Also I am looking out for the videos Phil has made.

Hi Tony,my extra throttle return spring is two bits of wire tied to carb throttle leaver and the other one mounted to the oil filler tube with a small spring in between,not very authentic i know but it works,and i think i have a heavy foot on the throttle and am in too much of a hurry when changing gears,so i need to improve MY skills a lot,well this is what i have arrived at after reading all the good advice from everyone,thanks guys.

Ken, great to hear your throttle return set is the same as mine
