Hi all.
So last week i decided to change the gearbox and transfer box oil, They were both very low on oil
After refilling with EP90 I noticed a slow drip from where the output shaft meets the transfer box (from part no, 236548) See red arrow below
So i ordered a new oil seal (FRC1780). I read some advice that I should buy a Corteco seal, so I did, and to do the job properly I bought a new oil seal housing (236541) and even a costly new output flange (539993) plus gasket, nuts, bolts.......etc.
After fitting it all I gave myself a pat on the back, admired the shiny new parts, and pumped in 2.5lts of oil.........................and then noticed a steady drip from exactly the same place as before
When I was seating the oil seal in the housing i tested the flange and it wasn't a tight fit, but I thought it must be ok as they were all new parts! Although I don't understand how it can seal 100% if it has to rotate?
So I was hoping for some advice on the seal etc. Is there a better brand I can buy? Could I have done something wrong? I have noticed some seals are part metal (see below) where most (including the one I ordered) are hard black rubber.....confused
Thanks in advance,
Mart
