hi millva'

by standard size i meant 1/4 inch fitting and the opening centered on the tip...

there are other standard (sae) sizes and metric too!

also there are a variety of the 1/4 inch tips (angled, side) and they all will work on the haha zerks.

i suggest getting a typical hand pump like the 1st pic and adding a 12 inch flex tube, if it doesn't come with the kit...

most auto supply shops will have all of these things...

the final product looks like the 2nd picture..

AND if you want absolute assurance the fitting will fit...

take along one of your EXTRA ZERKS to be sure,

you do get some extra zerks right?

cheers

i use the same g.gun and same tip, to lube the stabilizer jacks on the trailer.

Thanks once again 2air'

Any specific grease?

from the pix associated with the earlier posting on this u can see i use...

red grease

it's a syn lube forumula.

there are almost as many threads here on 'type of grease' as there are axles or tow vehicles...

i'm sure most of the typical automotive greases will work, lithium, molyb, syn and so on...

i use the red stuff because i can SEE it better when it oozes out of the bushings (which are black) and displaces the dark, older stuff...

What great timing on a very good topic. Expecting to pick up my 25' fb next week, I have decided to trade in the Sequoia and purchase a solid tow vehicle. (Any suggestions? I was going to look at a Dodge 2500) My other potential investment was going to be the ha ha (great abbrev!). Keep up the thread and educate this first time RV'er.

With the location of the zerks, the style of gun with the flexible hose, like shown on the right above, is really the most convenient and easy to use.

[SRW]

I have pretty much used all of two small tubes of grease (6" x 1/1/4 dia) and have never seen grease oozing from anywhere. This is after the dealer said they had greased the hitch.

Probably should buy a larger grease gun and use larger tubes?

[SRW]

I still use the ratchet that came with the hitch to tighten the spring bars' 3/4" hex nuts, but I have noticed that some folks use an electric drill.

Will any electric drill do for tighting the hex nuts?

Also, where do you get a 3/4" socket that has a fitting that will go into the drill's chuck?

I have looked with no success.

Have always had good luck with Makita

Just bought the combo set, needed a new drill anyway, the 1/2 drive socket

adapter I got at Home Depot.

Got a good deal on the combo set on e-bay

yea the small grease gun cartridges hold about 1/5th as much grease as the standard size...

as i recall richL used the small size (4 awhile) and it took 20+? pumps before old grease was dispelled from the bushings.

since the haha springbar head/bushings should be greased OFTEN (manual says 500 miles) those little cardridges don't last long...

typically requires 4-6 pumps with the bigger gun, AFTER the bushings are really really filled the first time.

i'm using about 2-3 cartridges/year, and they are also used on the stabilizer jacks.

depends on if you are using the tongue jack to raise the trailer, which reduces the torque required on the screw jacks....

IF tightening without the tongue jack my 18v cordless will just handle the torque needed,

but it spins 'em right up quickly IF the tongue jack is used to establish 'level' first.

i use a typical 3/4" craftsman socket which takes a 1/2" ratchet driver...

there are hex/driver-drill-ractchet adapter-thingies, in all the popular driver sizes that match the socket set...

see pic below.

Thanks for the reply.

You may have touched on the something that I am doing out of sequence when I hook up.

I have not been tensioning the spring bars until after I raise the tongue jack.

Got to ask another question, and as far as I know its not in the haha manual, is the correct hook-up sequnce to first tension the spring bars and then raise the tongue jack?

it may not be in their manual? but we've covered it in the users guide some

i don't think it matters, but it IS a lot easier to tighten/loosen the screw jacks,

manually or with the cordless driver, IF the trailer tongue jack is still supporting the load.

the key is knowing which notch/mark on the lower jacks is right for your rig...

typically i put the tongue jack down before loosening them and raise the tongue jack up after tightening...

occasionally in a really odd campsite (with extreme inclines or dips) i don't use the tongue jack assist.

OK, belay last.

After a careful reread I do see that "Step 10" says raise the tongue jack.

That's NOTwhat I have been doing. As I said I have been raising the tongue jack, and then tensioning the spring bars.

I suppose the key is learning how to read.

Thanks again.

[SRW]

A HAHA workshop at this summer's international would be a great idea.

I am off to get a full size grease gun.

Just hooked up and did not raise the tongue jack until after I tensioned the spring bars.

My drill did just fine. Plenty of battery and torque.

Greased using the full size gun. On the right zerk it took about 5 pumps before grease oozed out of the bottom.

For some reason couldn't get any grease into the left zerk?

Very little, but still some groaning when I pulled out.
