Folks, I know this forum is all about things gator. But maybe someone has experience with a Buck? It's one tough son-of-a-gun and has served me well for MANY years. I've never done anything but change engine oil/filters/batteries. It just goes and goes. But I'm getting concerned about the front differential. It has started to "yowl" in reverse. I have no idea of the lube required - I'm sure its way past time to change it out.

Advice? Lube type?

Thx, JRH

I have the original Ops manual. In the maintenance section for service intervals anything other than the most simple of simple tasks state "Dealer Service Required" or something to the same. As for Lubrication nothing is specified for the differentials.

Over all the years it still has just less than 100 hours on it. The seals are tight without any signs of seepage. Overall its had just transportation duty. It has the power and gearing of much more but its over all weight is less than adequate for safety. It's just a low speed, light load work-a-holic with a solid rear axle, swing-arm suspension. I've always loved the geared automatic/manual xmission.

Guess I'll have to find and buy the danged shop manual.

Mr 200mph, Thank you sincerely. It's not in my OEM manual but no matter - I will absolve my lack of maintenance sins tomorrow. I just happened to have a case of gear lube for everything else ready for this small project. If the lube comes out nasty I'll submit myself for a threshing.

The Buck gets more use now. The Land Cruiser in the background has yet another sheared front axle. Sigh. Use a tractor when a tractor is justified. A Land Cruiser is not a tractor. It wouldn't be problem except for a gov-locker in the front. The axles just can't handle a locker in low range.

No problem. The info was in the owners manual provided using the link posted earlier.

Good luck with everything!!!

Here is a link to the Operators Manual for the Buck 500.

Look at the index on left hand side under 鈥淪pecifications鈥 from there you should have all the information you requested.

Yeah, yeah. You are right. Back in another era this Buck 500 got much more use. But where we are now the 6x4 gets much more use. I mainly use the Buck when I don't need to carry anything which is rare. I do have a 'lil plastic JD dump trailer but the past the gate is very rough and ancient logging trail(s). The trailer tends to empty itself regardless of speed :-(.

So, here is another question: The grease zirks on this Buck are straight. There is no way for a std coupler to hold on so greasing the front end is messy. In addition, several of these zirks are in places that a right angle coupler is needed. I haven't found a coupler for this style of zirk - let alone a right angle coupler. These zirks do not have a hex so it leads me to believe they were pressed in and not threaded.

The 6x4 has standard zirks.... Any ideas?

BTW 200mph, thanks for the specs sent previously.

Check out Lock n Lube for grease gun couplings, these couplings make servicing your grease fittings so much easier. They also have 90 degree couplings for those pesky right angle zirks.

If you should ever need parts look at Power Sports Nation in Norfolk Nebraska they鈥檙e a large used part warehouse for UTV鈥檚. I noticed they have a fairly large assortment of used parts for the Buck.
