Blur gear oil

[zuman]

I just got my new Blur home two days ago and noticed today that the nylon gear oil plug was nearly completely unscrewed. How can I tell if there is an appropriate amount of oil in the case?
Thanks.

Check the dipstick to see if it has oil in there, otherwise you may just want to change the oil, adding some can be done, but you dont know what brand was used, so you may just want to drain the oil and put some new oil in there.

Since that opening is used for filling the tranny gear case, you might be OK. Unlike the engine oil filler cap, however, there is no dipstick. Probably the best way to tell if you've lost too much lube is to remove the nylon plug completely, then remove the drain plug on the bottom of the case and collect the lube in a measuring cup that reads in cc's (milliliters). The service manual indicates that there should be anywhere between 90 and 110 cc's in the case.

Coupla things to watch out for:

1) When re-tightening both the fill and drain plugs, take care not to overtighten. The nylon plug can strip very easily, and the metal drain plug can strip out the threads in the case body. Best to use a torque wrench for that one.

2) When replacing the gear lube, do not exceed the recommended amount. Doing so may cause excess lube to be expelled from a weep hole behind the case, and it'll wind up on your rear wheel and tire. Enough lube on the tire, and it's gonna be skid city. Been there, done that.

If you're not comfortable with doing the wrenching/draining/filling yourself, then your best bet is to take it back to the dealer since he's the one that probably didn't tighten the plug properly in the first place.
