Making a BGB last another 30 years

Recommended Posts

I am pretty particular to make sure my BGB's always have the right fluid level. But, I was thinking, should the fluid be changed annually or at some other interval? My tractors get little use, maybe 2-4 hours per month. Anything I can do to make sure they go as long as possible, I'll do.

Scott, No need to change them very often. Based on what you mow, even the mower could go for at least 5 years between changes. There is really no need to change the fluid annually, especially on the show machine or the parts machines.

Ok thanks guys. On some things, I am happy to be an over-maintainer. I'll keep up my routine of regular level checks and maybe drain/refill every couple of years just to make myself feel better :D

I do mine annually for paranoia sake and keep topped off with Lucas sticky gear oil. One dead give away is the gear whine, same as the trans. If the seals are good the outside is clean, and the consumption should be minimal. If the outside is leaking and wet, it would be worth the minimal cost to redo the seals.

Rod, I was just going to mention the water thing, that's important but also as you all know you can get water in a gear case through condensation particularly if the machine is exposed to temperature swings like being stored outside. Also frequent washing can lead to water in the bgb as for some reason there is a vented plug at the top of the bgb just where water collects when you wash it! As mentioned annual changing really isn't needed but checking the level and watching it's condition is needed at a minimum of at least twice a year IMO, more often if it leaks. The lube should definately be changed anytime it starts looking like a choclate milkshake! Just my 2 cents, value accordingly!

avoid lucas many hard core gear heads will tell you that it causes foaming and high RPM those little crank deals at the store are funny at 10 rpm sm00. Please please never ever run it in a engine. But hey that's just my opinion! Anyway run a good sythetic 90w gear oil and never chnage it and it works better when cold.

I had an issue with Lucas foaming in the BGB a while back. It has Mobile 1 80-90w synthetic gear oil now.

Glad to hear you have good luck with it.
