Gear ratios.
Posted: Thu Jun 18, 2020 8:12 am
Hi all,
Wondering if anyone could advise on the following. I have a Mk1 Haf I am restoring with the four speed gearbox, I want to increase the road speed by changing to the higher ratio gears in the hubs, will this exert too much strain on the engine? if so I have a spare five speed gearbox & shorter centre tube which I can fit, basically are the ratio's of the four gears used in the Mk1 box the same as the one's in the five speed box other than the crawler (fifth) gear & the different intermediate shaft i.e. the gears in the larger front section of the five speed box? To put it another way, if I just change the ratios in the hubs & retain the Mk1 four speed box will the gearing be the same as a Mk2 five speed box other than the crawler gear?
I hope this makes sense! any advice would be appreciated.
Thanks in advance Bill.
