tweaking a major

Hi - I was speaking to someone at a rally who said he'd 'wound up' the fuel pump on his new performance to get more revs to increase the road speed - so 2 questions:
- is this a good/bad/stupid idea?
- can it be done to a '52 E1A?
Regards,
Dan.

Hi Dan
Its your tractor you can do what you like
on a personal note i would not bother why stress that engine you could end up with bouncing valves if you go too much. The original cranks are not that strong in a 52 motor if it still has it fitted anything could let go in there
. most of them broke cranks at regular RPMs
.
I used to tractor pull and push motors way past the limit but it was my risk if it blew up, it was not going to be a suprise you kinda just expected it one day
Regards Robert

Hi Dan,
You are not the first person who wants to make his Major runs faster on the road.
I would like that too, but I haven't found a good solution yet.
Revving up the engine can be done till 2.000 rpm (without pulling a load), so that doesn't increase the roadspeed much (standard 1.800 rpm).
Revving up the engine more will ruin your engine.
Every bolt will come loose.
You could take some bigger wheels (18.4x38), but than you will have to higher the mudguards (and perhaps mount bigger front wheels?).
The effect will be limited to 10 km/h, but the costs wil be quite high.

Hi Dan,
If you really want to speedy up, its best to buy a JCB Fasttrac.
The Major engine, steering and brakes are not really suited to speeding. Think about your health.
Reving up a little, as Pascal says, doesn't hurt, but the fuel bill wil rise more quickly then the road speed.
Larger wheels and tyres is the best. HOw many time you can save per year?
Kind regards,

Thanks All,
I rather like keeping my major original, but when someone mentioned getting a couple extra mph from a little adjustment it sounded too good to be true - the current 12mph is a nicely relaxed pace, but I know from my orange tractor that 15-16mph makes a big difference - think I'll leave be and stick to the orange tractor for speedier road runs.
Regards,
Dan.
