2airishuman,

I would only add a procedure that I use when tightening the bolts in the stinger (relevant to your post number 133). Before I tighten the bolts, I put a floor jack under the rear of the stinger and force it into the upper most position, where it should be after the WD forces are put onto it.

I do this on any hitch that has slots and a rivet to stop the movement. By doing this, I am assured the adjustment is against the rivet stop, and not somewhere in the adjustment of the slots. Not necessary for sure, but just gives me a little peace of mind that I had the adjustment correct when I tightened the bolts and it did not slip while tightening.

good idea steveH!

i fiddle around with lifting on the stinger while tightening,

and never considered using the jack that was right behind me, DUH!

cheers

Hi, and if you don't have a jack, shame on you; You can insert the stinger into your receiver upside down and gravity will hold it in place while you tighten the bolts.

Bob, That's a good idea. On just about any other hitch, I'm sure it would work great. However, at least on my paticular ProPride, the fit was very tight, and I had trouble getting it to adjust, so used the floor jack procedure.

It was almost too tight, but I guess that's a lot better than too loose.

Is this sour grapes, or is there something to this information? Having two different tow vehicles, I would love to have a height-adjustable hitch bar.

What are your thoughts?

Brian

Hey Brian,

I'm not sure I saw an answer to this so I thought I'd chime in.

Their answer is ALWAYS they tried it and it didn't work. They say the same thing about the yoke. I guess I had my head under the desk for all the years they were trying these ideas with none of them working. I was only the vice president of the company and had lunch with the owner on an almost daily basis when he wasn't in Florida. All the trying of different parts and designs must have been HIGHLY classified. {sarcasm intended}

It works GREAT. In fact, every other hitch company on the planet has figured out how to make an adjustable hitch bar work.

You can draw your own conclusions as to why they can't.

Sorry about the hijack 2Air'. Sometimes I just can't help myself.

This is a GREAT thread and has been VERY helpful to a number of people who have decided to become new ProPride hitch owners.

Big Brown Truck delivered my PP today. Its raining here so I'll install it tomorrow, but for now, let me just say that this hitch is pure beef. Pictures do not do it justice. Well packaged too.

2air,

Is there any appreciable difference between the PP and HaHa in terms of backing up?

yep the packaging is really something.

i was planning to post pics of the 'pak in place' expanding foam.

it's amazing stuff and SO much better than the cardboard internals used by the other brand.

with parts that weight so much ANY movement inside a normal box results in cosmetic damage to the contents.

this is NOT an issue with the pp packaging.

i am SURE sean spent time AND effort and $ getting this packaging issue right.

gotta love attention to details, even the wrapper.

hi aage

no not really.

they both FIRST move the tongue slightly L/R before the wheels start rolling.

the jacks are slightly different and the yoke replaces the 'strut bars' so there are some subtle differences...

but from a functional view backing is the same.

as covered in the haha thread, one can use must sharper angles when backing or turning...

and THAT is an acquired skill or booby trap.

DISCONNECTING is somewhat easier with the pp since the hitch head/box seems to LET GO of the stinger with less fiddling.

do you have a specific concern or issue?

are u thinking about using one of these contraptions?

tell us more.

cheers

Well, it quit raining, so I have begun the install. So far I've got the stinger set up for my rig, but I've ran into a small issue with the W/D jacks. The adjustment bolt that you tighten against the frame is about 2" too long due to interference with my battery box. The other I think has been mentioned, I need to get a little longer bolts and a few washers to space the LP tank base about 0.5" off the frame to clear the u-bolts for the yoke crossmember. Nothing a quick trip to Lowes can't fix.

right u are!

the long bolt/short bolt issue is covered by devo in post #39...

1/2 inch full thread in 1.5-2.5 inches can be substituted OR SHORTEN the ones shipped.

devo also did the LP tray/tank lift mod in post #40...

and you may end up cutting OFF the forward jack guards/bumpers to properly fit the LP tank cover, see post #43.

don't forget to take pics and hang 'em here !

cheers

Okay, on my list...

INCLUDE the shorter adjustment bolts along with the longer bolts we now send.

The longer bolts were meant to kill two birds with one stone (bolt). If a trailer has a C-Channel frame the longer bolts will reach all the way under the flange of the 'C' and all the way to the upright of the 'C'. That's the reasoning.

Anyway, I know it won't help Airstream01 but it will help in the future.

So I was doing a little research last night on bolt torques. I tend to overthink things, and there was a line in the PP instructions that gave me pause. On page 21 it states: "Check that the hitch bar bolts are tight and torqued. These should be as tight as you can get them. 150 ft-lbs or more of torque."

Now an over-torqued bolt is on its way towards failure, so I did a little research to determine the SAE rated torque spec for the primary load bearing bolts in the PP hitch apparatus.

For the 5/8-11 grade 8 bolts used on the stinger, the max torque is 190 ft-lbs
For the 3/4-16 grade 5 bolts used on the yoke, the max torque is 270 ft-lbs

Basically my point is do not tighten any of these bolts as tight as you can get them, especially if using a 4ft cheater bar. Use a torque wrench properly rated for the amount of torque. And if I remember correctly you should ideally use a large enough torque wrench so that the value you need to reach (ie 250 ft-lbs) falls within a 20%-80% range of the max rating of the wrench. So in this case you'd want the torque wrench to be rated to around 325 ft-lbs so the 250 ft-lbs falls in that range.

2air, on post 17 your photos clearly show you have the big arse flat washers on both sides of the bronze bushing. The instructions do not mention this (unless I missed it--quite possible), but only say to put one flat washer under the head of each big arse bolt. I believe the way you have it is correct, however and will be how I am going to install it in a few minutes.

Sean, is this the correct way? Thanks

Brian

Yes, one on each side of the bronze bushing.

Previously, we only used one washer but I changed it to one on each side just because it made more sense to me.
