I just replaced the oil in the gearbox lovely new oil which GB oils made up specially and it started running out of the underside of the belt pulley on the side I have drained the oil back out of the gearbox and now i am needing some information on how to fix this leak I assume its just a seal gone? where would I get one and how do I go about taking the pulley out?
thanks all
Oli

Hi Oli,

Just undo all the bolts and the pulley should just come out. Ive just used Loctite sealant when i replaced my pulley. we use it all the time at work to seal hydraulic mating faces.

its leaking between the pully and the housing which bolts to the side of the gearbox

if it's leaking between the pullywheel and the pully housing you have to change the seal 64mm x 90mm x 13 mm it;s not a standart size , but is availeble ( i dont know the english size )

losse the big nut, and get the pullywheel off, then change the seal , and at last , mount the pully wheel

(and look if there is much play on the bearings) if there is a lot off play replace the bearings too , the two bearings are 6406 and 6210

I believe you can get this seal from Old 20 tractor spares. They have a shop on eBay

Thanks ive discovered the problem my major didn't have a seal in .... that's why the oil was low when i bought it got a seal ordered on its way

thanks for the help
