No problem. Just confirm ratio and tyre size to work out how many teeth needed on the speedo gear.

Hi,
Have got a Series 80 Landcruiser 1991 and need to correct the speedo for 35" tyres.
Presume the odo driven by the cable.
Is the speedo driven by the cable or is it electronic from the speedo drive.
In theory as it is a diesel need to correct the odo.

Who sells adaptors to correct the odo ???

Other option if it is electronic speedo to just correct speedo and hope certifier doesn't object.

Thanks
Tim

my certifier was happy with me testing the speed on my gps and just putting marks where 50, 80 and 100 were

hi suzolla ,i went to 4wd accesories i think it was in chch,let them kno what ratio i needed and they ordered in the right adaptor,it just screws into the original gearbox output and the cable then goes into the adaoptor,or if urs in electronic u can get units installed to correect this,my adaptor cos 230 i think from memory but its a 1 min job to put in,also if i ever put oringinal wheels back on i just pull it out,hope this helps

(Just along from Grove Mitre 10 - or what is left of it)

They do mechanical and electronic speedo drive correction and have a rolling road to get it perfect.
I will be using them in the near future to get a mechanical to electronic speedo drive made as I am putting a SJ410K transfer box in my Jimny.
