Are you trying to get more speed out of it? Is the cart stock?

Thanks for the response, 20X10-10 tires, 3 inch lift, speed code 4. Yep, more speed.

Can't believe no one out there has changed the gearing in a Graziano differential that can comment here.

How much more speed are you looking for?

Not really looking for help in the quest for speed. Just want a little insight into changing the gears, any special tools needed and things to be watchful for, etc. Thanks for your reply.

Sorry about that... thought that was the purpose for changing out the gears.

It is about speed of course, but just wanted some insight on changing the gears since this will be the last upgrade concerning speed I will be doing in the near future. I will be doing the gear change this weekend and will post back an answer to my own question for others that may need this kind of info.

Thanks for your response, I appreciate it.

I completed the 8 to 1 gear change this weekend and it isn't too bad a job. Remove the battery plus/minus cables after switching to TOW. Remove the cables at the motor and drain the differential oil. Remove the differential then remove the motor. Only loosen the bolts that hold the differntial housing together then stand the axle upright with the short end down. Remove all but two of the loosened bolts (these should be across from one another, back them off about 1/4 inch so in the next step the housing doesn't come apart unexpectedly) while stabalizing the unit tap the housing with a deadblow hammer to break the sealant bond then remove the last two bolts and separate. The gears will now be exposed, they will have to be remove all together (3 pieces). Once removed the bearings will need to be removed using a bearing separator with puller and then mounted on the new gears using a small press. Reassembly is the opposite of the above also refill with oil (22oz). My cart gained about 7 MPH (up to 26.8 from 19. but has a slight whine from the new gearing but the knobby tires are just as loud. I am pleased and hope this information helps someone in the future.
