My laptop has been giving me fits, so I haven’t posted for several days. I thought my hard drive was about to crash. The cursor would suddenly freeze and the laptop would become unresponsive for long periods of time. A couple of days ago, when it started working again after about 40 minutes of no response, I found Malwarebytes was running in the background. I ended the task once the laptop resumed working and the laptop seemed fine. Last night it happened again. This time I uninstalled Malewarebytes and the laptop has been fine. I’ll keep my fingers crossed.
The weekend weather was nice in Sutherlin – temps climbed daily from 70 degrees on Friday to mid-70s on Saturday and Sunday, hitting the 80s on Monday. Saturday morning we disconnected the 50amp electric service, water and sewer and battened down the hatches for a short drive into town. Les Schwab called around 9:30am and said our tires had arrived.
We pulled behind the shop and were directed to an outdoor covered work station. I checked the codes on the new tires to confirm the production dates – they were all 1419. As I wrote in my last post, tires have Department of Transportation (DOT) codes on the sidewall. The codes are alpha-numeric. The letters indicate the factory that produced the tire and the numbers are the calendar week and year of production, so 1419 means these tires were made the 14th calendar week of 2019.
Having fresh tires on an RV is an important consideration. Tires begin aging soon after they’re made – especially if they’re exposed to sunlight. Our old tires had lots of tread left – the tread depth was 13/32″ deep. Tires aren’t considered worn out until the tread depth is 3/32″. But, our tires had aged out. I found weather checking on the sidewall of two of our tires.
The checking was wasn’t deep and we would most likely be okay for a while longer. But I don’t like pushing such an important safety issue as tires. A blowout on a motorhome can be a catastrophic event.
The guys at Les Schwab did a fantastic job and had all six tires replaced in about an hour and a half. I had Equal Flexx brand balancing beads put in all six wheels. New shoes and a smooth ride!
With the Spyder down, we had nowhere to go and not much to do all weekend. Donna took the time to make a few dishes of “comfort food” so we would have some leftovers – we plan to boondock for a few nights as we head north. She made a Greek pork stew that was tasty and a big pot of pea soup.
Monday morning we hitched up the trailer and I pulled it into the street. I tried to back the Spyder into the trailer with its wounded engine thumping on one cylinder, but it wouldn’t go up the ramp without stalling. Luckily, a couple of guys were working nearby and helped me push it up the ramp into the trailer.
We drove about 15 miles up I-5 and exited near Anlauf. From there we hit a county road called Territorial Highway. This was a twisty road with lots of short, steep climbs and downgrades – and no shoulder in parts. All along this route, we saw signs for wineries. If the Spyder was operational, I could see us taking winery tours in this area.
Our destination was Richardson Park – a county park/campground on Fern Ridge Lake near Veneta, west of Eugene, Oregon. I had an appointment set for Tuesday morning at Source Engineering in Veneta – about 10 minutes away from Richardson Park.
Last summer, we had a cooling fan failure on the coach. The cooling fan is driven by a hydraulic motor. The speed of the fan is regulated by a wax-valve thermostat. The wax in the valve expands with heat and drives a tapered piston into a seat where the fluid bypasses the fan motor. When the piston fully seats and closes the bypass, the fan runs at its highest speed. When the wax is cold – meaning the coolant is cold – the valve is open and fluid bypasses the hydraulic motor and the fan doesn’t turn.
When our wax-valve failed, the only replacement parts I could find were in England and would take a week to arrive. So, I had a stop-gap repair made that was intended to be temporary. I had the line for the bypass capped off so no fluid could bypass the hydraulic motor. This meant the fan always ran at full speed regardless of temperature. This really wasn’t harmful – the coolant temperature in the engine block was regulated by the thermostat in the coolant passage. But it has drawbacks – it takes horsepower to drive the fan. The amount varies with engine speed, but it takes an average of more than 30 horsepower to drive the fan. This in turn reduces fuel economy. Also, there’s the wear and tear of running the hydraulic motor full-speed, full time.
Later, I found out that Source Engineering had the Sauer Danfoss wax valves. They make a conversion kit to retrofit the mechanical wax valve system into late model coaches with electronically controlled cooling fan motors. The electronic control units have a high failure rate – I often hear newer Monacos or Holiday Ramblers with their fans running at high speed at start up as they leave an RV park with a cold engine. The mechanical wax-valve system rarely fails.
On Tuesday morning, we left the trailer in our site and drove to Source Engineering’s shop. We arrived at 8:15am and they took our coach in straight away. It took about an hour and a half to get the hydraulic lines uncapped and sorted and the new valve installed. They also added a restrictor to the bypass line so the fan will always run at a minimum of about 800 rpm. This is a good idea – regardless of temperature, the fan will draw air across the charge-air cooler and condenser and if the wax valve ever fails, the fan will provide some cooling. At full speed with the wax valve fully closed – this occurs at 198 degrees of coolant temperature – the fan turns at 2,500-3,000 rpm.
I had another issue for them to look at. Our front sway bar bushings are worn and the sway bar is loose. I tried to tighten it, but it seems the loose bushings allowed the bar to rub and damage the link rod threads. I couldn’t tighten it. They checked it out and confirmed the links needed to be replaced. The bad news was, they didn’t have the links we needed in stock. The good news was, they could get them from Roadmaster in Vancouver, Washington and have the parts in a day or two.
So, we extended our stay at Richardson Park until Thursday, possibly Friday. Richardson Park isn’t a bad place to be stuck. It’s a beautiful park with paved sites and grassy areas and lots of trees. And it’s right on the lake. Fern Ridge Lake is a reservoir on the Long Tom River. It covers over 9,300 acres and is a little over four miles long. It’s a popular spot for sailboats, power boats, water skiing and fishing. In the summer, the prevailing wind from the north is strong in the afternoon making it ideal for sailing. There are boat clubs and marinas on the lake.
Before we returned from Source Engineering, we made a detour to hit Walmart in west Eugene – about 12 miles away from Veneta. Donna needed to pick up a few items to meet her menu plans for the rest of the week and I took the opportunity to stock up the beer supply.
Between the Spyder, the sway bar links and my laptop troubles, it seems like everything is going down at once. We’ll get it sorted. Next week I’ll drop off the Spyder for repairs while we visit family in Arlington, Washington.
The weather here has been unusually warm. Yesterday the high was 91 degrees – about 20 degrees higher than average. Today will hit the mid-to-upper-90s before things start cooling off. Mid-70s should be the high by the end of the week.
