4rt gear oil white

Featured Replies

hy is this normal iv just dropped the gear oil on my 4rt and its like a white colour i havnt changed it for a while and cant remeber what colour it was when i put it in but it was motul there isnt any extra oil just normal amount so it shudnt be the water pump water passing

A milky white fluid generally is condensation of some kind. It could be two things: one, if coolant is leaking into the gear oil and, two, if the transmission vent is blocked, moisture will be drawn in when the bike cools.

i was hopeing you wernt going to say that it could be coolant cos that would mean water pump seal and shaft are gone could it just be the oil has had its life because i havnt changed it for over 20hrs use

Even old oil will not turn white.

not sure thats the first thing ill check the thing i dont get is there was hardly any oil come out would it do it any harm putting some other oil in and running it abit to see again

if it is water pump is it just a seal change or more to it and ruffly how much regards ste

Some of those questions are above my pay grade as, i bought mine new and haven't had to do those type of repairs yet. The diagnosis came from 50 years experience. Sorry i could not help you further.

B40RT had a good question. Has there been a loss of coolant? That would be a good indicator that it wound up in the gearbox, if so. The other thing that bothers me is, you mentioned the gear oil level was low. Has that gone into the coolant system? Is the coolant a muddy brown liquid now? This could open a whole new can of worms.

Stand a warm bike in a stream and the cooling gearbox will suck water up the vent pipe.

And is a very good reason to have the vent go up to the headstock.....
