MX83 Cressida starter solenoid contacts

My starter solenoid contacts wore out. Here is info for a Cressida/Crown/Supra with a denso starter.

Although the denso starter solenoids are fairly common, I wanted to make sure I was ordering the right parts. Many rebuild kits on ebay and amazon are vague in their application list, and vague is never good.

I checked my part number of my starter solenoid as 28150-41060 as used on 5M, 6M, 7M, RZ engines. As I couldn’t find a rebuild kit listing exactly that part number, I took it apart and here are the dimensions I measured:

  • ~20.65mm Plunger body diameter
  • ~36.8mm Plunger ring contact diameter
  • ~96.65mm Overall rod length including top hat
  • 8mm diameter terminal posts outside the body of the solenoid
  • Extended wing (‘C’ shape) contacts – ~21.5 mm wide. Type 1 on the photo below:

This is valid for 28150-41060 only. If yours is a different P/N I encourage you to measure it – you need to take it apart anyway. When getting a kit, make sure to get one that includes a plunger, as the ring on it is a wearing contact too.

D-Link DWA-131 rev. E on Linux

Today’s topic: The D-Link DWA-131 Wireless N Nano USB Adapter.

Early models in round cases used chipsets which now have inbuilt support (rev A- realtek 8192su, rev B – realtek 8192cu), but the newer ones (revision E) use a realtek 8192eu. There is a driver available from D-Link, but for me it was a kernel-panicky mess.

This is a list of instructions that I used to install a driver hosted by github user jpostma which seems to be the official realtek driver with patches (for what? not sure, but it works) applied.

User Brainiarc7 suggests using https://github.com/Mange/rtl8192eu-linux-driver which also has patches applied, as it is “Newer, and currently under maintenance.” I had a look at it, and it already has the DWA-131 device id, so I recommend you use it first.

This is for an ubuntu based linux distribution, but for others the principle is the same.

Plug the adapter in and determine the device ID, ensure it is 2001:3319 otherwise you have a different device:

$ lsusb
Bus 001 Device 004: ID 2001:3319 D-Link Corp.
...

Ensure you have the necessary prerequisites:

$ sudo apt-get install linux-headers-generic build-essential git

Clone the github repository with the driver source code:

$ git clone https://github.com/jpostma/rtl8192eu.git

Once the repository is downloaded, edit rtl8192eu/os_dep/linux/usb_intf.c
and add the device ID of our card, at around line 321.

#ifdef CONFIG_RTL8192E
    /*=== Realtek demoboard ===*/
    {USB_DEVICE_AND_INTERFACE_INFO(USB_VENDER_ID_REALTEK, 0x818B,0xff,0xff,0xff),.driver_info = RTL8192E},/* Default ID */
    {USB_DEVICE_AND_INTERFACE_INFO(USB_VENDER_ID_REALTEK, 0x818C,0xff,0xff,0xff),.driver_info = RTL8192E},/* Default ID */
    {USB_DEVICE(0x2001, 0x3319),.driver_info = RTL8192E}, /* D-Link - DWA131 Rev. E */
#endif

Edit rtl8192eu/Makefile and change 2 things:

  1. At about line 16 add a # to comment out a flag that causes compile problems on recent kernels:
    #EXTRA_CFLAGS += -Wno-error=date-time
    
  2. At about line 42 edit the line to switch power saving off:
    From:

    CONFIG_POWER_SAVING = y
    

    To:

    CONFIG_POWER_SAVING = n
    

Compile the driver:

$ cd rtl8192eu
$ make

If there are any problems with compilation go back and fix them (install libraries, etc.) before proceeding.

Install and load the driver:

$ sudo make install
$ sudo modprobe 8192eu

This is what worked for me, and since setting it up it’s been flawless.

McCulloch 4000 chainsaw parts diagram and tuning information

Here’s a scanned parts diagram for an old McCulloch 4000 chainsaw, made in Italy, with a Tillotson carb. This is a little different than the ‘4000 California’ model.

The operator manual shared for the 3500/4000 series doesn’t have anything too interesting, but here’s the key information:

Fuel Mixture:

  • McCulloch oil 40:1
  • SAE40 2t 20:1

Chain Oil:

  • SAE 30 motor oil, or McCulloch chain oil no.201349
  • Refill the oil tank each time the saw is refueled

Tuning specs:

  • Spark plug gap: .5-.6 mm
  • Low speed base tune: 1 full turn out from closed
  • High speed base tune: 1 full turn out from closed

Service specs:

  • Chain tooth angle: 35 degrees
  • Every 10 hours: Remove sparkplug, clean and adjust gap
  • Every 20 hours: Replace sparkplug
  • Once a year: Contact your dealer for a full service (no explanation of what this includes)

There are 2 part numbers on the Toyota diagram!

If there are 2 or more part numbers for one part on your Toyota diagram, marked with a ※ (the x with dots means reference mark), look for a legend to explain further. Sometimes it’s on the next page. Different trim levels and equipment specification are fitted with different parts, usually this is made clear in the legend or part name.

However, sometimes you find something like this:

toyotaparts2

… Without an accompanying explanation. At first I thought it was a range of chassis numbers, but they’re actually date codes in the form YYMM. I don’t know how Toyota aligns the change over, so ask your parts guy if you need to.

It took me a little while to figure out, so now you know.
