Changing gear lube

troper

I have a 99 g16 gas. I checked the rear end fluid and it looks milky and I do not know if it has ever been changed. Can you just pump out the old fluid or should I remove the cover and make sure it drains completely. Also, what is the best lube to use.
Thanks
Troy

My cart is an 83 G1A and I change the gear oil every 2 years with straight synthetic.I have't had any trouble

If your oil is milky its gotten some water in it.Mine gets lots of miles and its cheap insurance.

75w90 rearend gear oil (walmart brand is fine) and I change mine once a year unless I'm doing a lot of creek riding where the rear chunk gets under water. Also grease your clutches at least once a year.

I've been lurking here for a few weeks since I got my cart. Is there any step by steps on how to lube the clutches? Also any other routine maintenance that is suggested.

I've enjoyed seeing everyones projects and it's given me some ideas. I've got some corvette yellow from my old racing days. I'm thinking of lifting my G1 and painting it up and adding a few amenities.

Thanks!

I'm sure there is some threads around here somewhere about routine maintenance. You can also click on Yamaha in my sig, look up the owners manual and it should give you tips for routine maintenance.

As for greasing the clutches, it really depends on how much you use the cart. But on average once to twice a year should be fine. Just pump 2 to 3 in the drive and driven clutch. It's best to pull the cover off the drive clutch, clean it out best you can and then grease it. I usually never put more than 2 pumps in the rear clutch. If it seaps onto the shaft between the sheaves and onto your belt, it is a nightmare. It's also a good idea to keep an eye on your king pins in the front end. Good idea to regrease them if the cart is of some age.

If you have any questions or need help, just post them here and someone will help out. Lots of knowledgeable guys and tech's here on the site.

Ok, I had already downloaded the user manual but doesn't give much detail other than maintenance intervals.

When you say just a couple of pumps into the clutches, is there a zerk on them? If so I haven't seen it but I may be looking in the wrong place. Or do you smear it on surfaces? It's a '84 G1 if that helps. I found the zerks on the front king pins but that's been it.

Thanks!

Early buggies did not have zerks on the clutches. All you can do is disassemble and clean them, and smear a little grease on the sliding surfaces. You will need a puller to get the secondary clutch apart. See the sticky above about installing a power spring. The primary does not have to be completely removed from the engine, just the outer cover and sheave. Remove the big bolt in the center of the clutch to get to the cover and weights, then the snapring to remove the outer sheave. The snapring is under moderate spring pressure, it helps to push the sheave towards the engine to ease removal and installation.
