Here's a shot of the switches. The leftmost switch spot is for a reverse light, so you can leave it out if you don't have one. The thread is M16x2.

Check out Nelson's article at

You're going to be stripping and reassembling the cover anyway.

However, on all of my covers, standard O-rings did not fit the recesses snugly. So I bought some "teflon backing washers" from MMC to take up the extra space. Also used "double seal" O-rings from MMC, which seemed to work very well.

Yup, thass right. Seems like I post a link to them at least twice a day, thought maybe I could get by without for once. Oh well, sorry bout that.

Not the cheapest source of such things, but they offer an amazing variety of hardware, tools and chemicals; and almost always ship them the same day.

The boxes they ship in are way too big,




but I may be pettty

Here's a photo of the top of my gearbox in my 1958 TR3A

And the hole for the dip-stick in my tunnel

I added a large hole with a large rubber plug for easier access to the solenoid on the left side. I also cut two smaller holes ( filled with rubber plugs) way up above the screws for access to the screws using a very long screwdriver. And I use regular slotted round-head screws to hole the solenoid that I can easily un-screw with the long screwdriver.

 

[TR3driver]

Wow, Don, do you really mess with the solenoid that often?!

Pulling the tunnel is no fun, I'll admit, but once it's set up you should be able to go at least 10 years without touching the OD other than changing oil.

Thanks much all. As soon as I saw the McMaster name it hit me, just never had occasion to go there before... and just when I thought I would get to bond with the Mercury boys. Going to need an assortment of nuts and bolts on hand for future use. And a tap and die set. I do have Nelsons article printed out, should have looked, just haven't gotten past the first page and the 1 1/4" nut yet. Just got back from Sears with the socket. This should be interesting.
