Offset Extension Wrench: The Secret to DIY RV Repairs in Tight Spaces

[mevman]

But have you got it yet?

yes...came DHL. Not sure what trouble others are having with the site. Safari had no warnings and ordering was straightforward.

These have been around for many years: Crescent CX6RWS7 - 7 Piece X6™ Black Oxide Spline Open End Ratcheting

And now I see these are available: https://www.summitracing.com/parts/wra-05020022001

I do have some of the first type shown. I find they don't fit a lot of tight spots because they are a bit too wide and require more movement.

The 2nd type (which is out of stock) I will need to try out. I cannot tell much by the photo.

How about a ratcheting crescent wrench? Be the first kid on your block to own one! Something you'd see on an infomercial.

Maybe it's just me but I've found most if not all of the inexpensive specialty tools that are infomercial type material to be mostly useless. Usually they are too bulky or clumsy, or hard/slow to use, or don't really do a job as well as a quality standard tool. One example I can think of is the socket with all the rods in it that is supposed to be universal. I've had one in my box for decades and never once have I found a use for it.

A lot of these tools are probably sold to people who give them as gifts to their mechanic/handy person thinking it is a revelation, and they end up in a corner of the tool box never to be used. I have several of those but I keep them because they were gifts from loved ones and I can't bear to throw them out.

If you are even close to advanced at doing mechanical work you know the feeling of a quality tool designed for a single task. No infomercial tool can replace that, best to stick with the wheel that has already been invented.

I tend to agree, but such a tool can really be a lifesaver in the right situation

My favorite is a hughe "Swiss army knife" with an incredable number of tools
I think it's this one

Totally useless of course

Running a distant 2nd to the offset extension is the flexible socket wrench extension.

 

[DonTom]

Running a distant 2nd

"Distant" is correct. I don't think I ever found a use for mine.

I just received my Klen Mate Offset Extension Wrench wrench today.

Mine is too thick and too large to be all that useful to me for most things. I will look for a much smaller one

This one is 15" long, but 1.5" wide x 0.5" and that 0.5" will be more when the socket is added.

The blue nut/bolt holder thingies look like they will be more handy than the main tool.

I will just put this in with my countless other tools that "I may need some day". I am not sure if that day will ever come.

We used to call a crescent wrench a Chinese socket set or knuckle buster.

I wish I had that problem.. LOL

If you use a tool once, then it is greatest invention since the wheel. (OR, I finally found a use for that $1,000.00 hunk of iron)

 

[CharlesinGA]

My Avast anti-virus also did not like the Wild Bear site. Note the basic unit comes in two different lengths, 13 inch and 16 inch, in addition to the different colors. The torque capability seems to be the same. If you have a lot of tools already, just buy the ones with the adapters.

A mobile mechanic wanted $1,975 to replace a $210 power steering pump on our diesel pusher.
I asked how replacing a pump could possibly cost that much. He just smiled. "Four bolts you can't see. Done a dozen of these. They're designed backwards — five hours minimum just for access."
My daughter's graduation in Colorado was three days away.
Then the guy in the next campsite came over and asked if we needed help.
What he showed me changed how we handle every repair now.
Let me back up.
Sandra and I have been living full-time on the road for just over two years. Sold our place in Pennsylvania, bought a 38-foot Class A — Cummins diesel, Freightliner chassis. Roomy enough to live in, tough enough to take anywhere.
The plan was simple. Chase the good weather. Winters in Arizona. Summers in Montana near family. No more property taxes. No more $500 electric bills. No more putting off life until retirement finally showed up.
For twenty-six months, it worked exactly like we'd hoped.
We did the Southwest. The Pacific Coast. Four months hitting Utah's national parks. Last summer we made our way through Idaho, timed it just right to get to Glacier before the crowds hit.
We were at a Forest Service campground outside Durango — a beautiful spot right on the river — when the steering went stiff.
I wasn't even driving. Just backing into our site. Power steering quit on me. I had to muscle the wheel with both hands just to get us straight.
I noticed fluid on the ground first. Little puddle under the engine bay. Popped the hood and saw it — power steering pump leaking from the seal.
No big deal, I thought. I've done power steering pumps before. Did one on my F-250 back in Pennsylvania maybe eight years ago. Took most of an afternoon, but nothing too complicated.
That was before I saw where Cummins decided to mount the pump on these ISL engines.
It sits down low on the driver's side, jammed between the AC compressor and the front engine mount. The mounting bolts face backward — toward the firewall — with maybe two inches of clearance if you're lucky.
I could see three of the four bolts. I could reach down and feel all of them with my fingers.
But I couldn't get a socket on any of them.
I tried my regular ratchet. The handle hit the compressor housing before the socket even touched the bolt.
I tried my stubby. Got it on one bolt, but I had maybe three degrees of swing. Would've taken all day just to back out one bolt.
I tried my flex-head. The joint collapsed sideways the instant I put any real pressure on it.
I tried my U-joint extension. Got the socket seated twice, started turning, and it popped off both times. Almost lost it down into the frame rail.
Five hours I fought that engine compartment. Five hours in the Colorado heat, hunched over a diesel that was still warm, sweat soaking through my shirt, knuckles all scraped up.
Sandra kept bringing me water. Keep saying we should take a break. I didn't want a break. I wanted to fix this thing so we could get to Fort Collins.
Our daughter Melissa was getting her Master's on Friday. We'd been planning this trip since January. Sandra had flown back in March to help her find the perfect outfit. I'd been working on my speech for weeks.
Fort Collins was four hours north. Graduation was in three days.
And I couldn't get four bolts off a power steering pump.
I finally gave up and started calling mobile mechanics. Found one who could come out the next morning.
He showed up around 9 AM. Looked under the hood for maybe twenty seconds.
"Yeah, these are a pain," he said. "I can do it, but it's gonna take most of the day."
He walked back to his van and came back with a written quote.
$1,975.
I asked him to break down the numbers.
"Pump's about $210 if I order it. Labor's $1,765. I charge $245 an hour, and this is a minimum five-hour job. Usually runs closer to six with these Cummins setups."
Six hours. For four bolts.
I told him I needed to talk it over with my wife.
He nodded, handed me his card, and drove off.
I went back inside. Sandra was at the table looking at her laptop.
"How much?"
I told her.
She closed the laptop and stared out the window at the aspens.
"We could fly up," she finally said. "Rent a car at the airport. Deal with the motorhome when we get back."
She was right. We could. But that meant leaving our home sitting here. Paying to hold the site. Paying for plane tickets. Paying for a rental. Paying for the repair whenever we got back. Coming back here instead of heading west to see friends in Oregon like we'd planned.
One busted pump was snowballing into a month of headaches.
I went outside and sat on the picnic table, just staring at nothing.
That's when our neighbor walked over.
Younger guy, maybe late forties. Name was Marcus. We'd chatted a few times over morning coffee — said he'd been on the road about six years. Used to be a heavy equipment mechanic down in Texas.
"Saw the mobile guy leave," he said. "Power steering pump?"
I nodded.
"What'd he quote you?"
I told him.
He let out a low whistle. "Let me guess. Cummins ISL. Bolts facing the firewall. Said it was five to six hours."
I nodded again.
"You got twenty minutes?"
I wasn't sure what he meant.
"Come on."
We walked over to his site — a gorgeous 2018 Newmar that looked like it just came off the showroom floor. He opened his basement storage and pulled out something I'd never seen before.
Flat steel bar, about 15 inches long. Socket connection on one end. Square drive on the other. Some kind of gear mechanism inside.
"Offset extension," he said. "Gear-driven. The only way to get at those rear-facing bolts without pulling the radiator and half the front end."
I told him I'd already tried every extension I owned. There just wasn't enough room.
He just grinned. "Watch."
We walked back to my coach. I popped the hood.
Marcus slid that tool down into the gap between the compressor and the mount. It went right past the obstruction that had been blocking me all morning.
The socket clicked onto the first bolt.
He handed me the drive end. "Go ahead."
I turned it.
The bolt moved.
Thirty seconds later, it was out.
Second bolt was seized — corroded to the bracket. But the wrench came at it from a completely different angle, got solid contact, and with some effort, it finally broke loose.
Third bolt was actually hidden behind a wiring harness. Took a minute just to find it. But once we did, the tool reached it no problem.
Fourth bolt came out easy.
All four bolts removed in under ten minutes.
I just stood there holding the pump, trying to make sense of what just happened.
Marcus was already wiping down his tool. "First time's always like that," he said. "You think it's impossible. Then you get the right tool and realize the only impossible part was what you were using."
I asked where I could get one.
"Online. About ninety bucks. I've got three of them. I wouldn't travel without them."
I asked if I could borrow his to finish the job.
"Keep it till yours shows up. I know where you're camped."
That afternoon, I drove into Durango and found an auto parts store with the right pump. $198.
Went online and ordered the same tool Marcus had lent me. Offset Extension Wrench. $79. Comes with adapters for 1/4", 3/8", and 1/2" drive.
Had it shipped to the campground host's office. Showed up three days later.
By then, I'd already installed the new pump using Marcus's tool. Total time: just over an hour.
Total cost: $198 for the pump. $79 for the tool. $0 for labor.
$287.
The mobile mechanic wanted $1,975.
I saved $1,688.
And we graduated.
Drove up to Fort Collins Thursday afternoon. I watched Melissa walk across that stage Friday morning. Gave my speech without missing a word. Took her and her roommates out to dinner and laughed until midnight.
None of that happens if I'd waited on that mobile mechanic. Or if I'd paid him $1,975 and blown through our travel budget on labor instead of celebrating with family.
Since that week in Durango, I've used the tool more times than I can count.
Starter motor on the generator — same issue Marcus had warned me about. Buried behind the turbo heat shield.
Transmission cooler line fitting — some engineer at Freightliner stuck it about an inch from the frame, which apparently counts as accessible.
Helped a retired couple at a KOA in Wyoming — their alternator bracket bolt had backed out and the whole alternator was hanging by the belt. Husband was ready to call a tow truck. Took me fifteen minutes.
Engine mount bolt — Cummins put it behind the oil filter housing where apparently nobody would ever need to get to it.
Every single one of those would've meant a shop visit. A tow truck. A labor bill that made no sense for the actual work involved.
Now they're just Saturday projects I knock out at the campsite.
Here's what I've learned after two years on the road.
These rigs aren't built for owners to work on. They're built for service centers with $200/hour rates and month-long wait lists.
Every fastener is buried. Every repair is "complicated." Every job needs "special access" that somehow takes six hours and costs three times the parts.
But it's not complicated. It's just hard to reach.
And hard to reach is a tool problem, not a skill problem.
When you have something that actually fits those spaces — thin enough to slide past obstructions and strong enough to apply real torque — the "six-hour dealer job" becomes an hour at your campsite.
Suddenly you're not at the mercy of mobile mechanics charging $245 an hour.
Suddenly you're not missing graduations and anniversaries and all the moments you sold your house to go experience.
Suddenly you remember why you're out here in the first place.
The tool is called the Offset Extension Wrench. $79. Works with whatever socket set you already have.
I'm not saying it fixes everything.
But I am telling you that someday — probably at the worst possible time, in the worst possible place — some bolt is going to be the only thing standing between you and the life you worked thirty-five years to finally start living.
And when that moment comes, you're either going to reach it or you're not.
I couldn't reach it.
Now I can.
If you're out here doing this — if you're sick of being told simple jobs cost $1,900 because of "access," if you're done watching your travel fund disappear into labor charges — this belongs in your tool kit.
Not because I said so.
Because a neighbor named Marcus in the Colorado mountains showed me what I'd been doing wrong for two years.
Link below if you want one.
Safe travels out there.
And if you see a gray 38-footer with Pennsylvania plates and a bike rack on back, give us a wave. That's us — still rolling, still doing our own repairs, still making every graduation we're invited to.
Sandra says your wife's got this.
