Hi Everyone - I plan to replace leaking oil pressure switch - can I do this with bike on centerstand and something to catch oil or will a flood of oil be released when I remove switch? Better to put bike on it's side?

What tool do you use to loosen nut - I tried a 15/16" short socket but will need a long socket to remove it - just wondering if there's any other way.

Otherwise, looks pretty straight forward.

Thank You,

Ken

You will need a long socket, I'm sure it's a metric size not in inches.

Not that much oil will come out, just have a few rags handy.

Make sure you have the proper crush washer.

Don't over torque it.

Good luck!

It's been a while since I changed mine but I recall the procedure called for draining the tranny oil first. Should be no leaking at all if you do that. If it's brand new oil just use a clean container and put it right back in when done if you like. I always use new gear oil since it's really inexpensive and good insurance.

I think we talk about the motor oil here

oil pressure switch <-> draining the tranny oil

15/16" socket was used to remove leaky existing oil pressure switch that did not have a crush washer.

Metric socket was used to install new oil pressure switch from EME (their house brand) with crush washer.

No more leaking R65LS

Well done!
Another happy ending!

Yes, 15/16 is 23.8 mm or about 0.008" smaller than a true 24 mm socket. Bolt heads aren't held to that tight a tolerance, so a 15/16 works on a 24 mm bolt head.

Some other SAE to metric equivalents can be found here:

It may be a bit confusing, but the values in the column "standard" refer to the SAE wrench size and the "metric" calls out the "pretty close" metric wrench that ought to fit. Or, vice versa, a SAE wrench of the size in the "standard" column ought to fit the metric head size in the metric column.

Hope this helps.

Best.

I'm over 60 now but still remember my high school science teacher saying OK.. we're all going to learn METRIC!!! Groaning and mumbling ensued of course but we had to learn it as Canada was committed to go metric. You know, like the rest of the world except the USA and Botswana or someplace like that. The Weights and Measures Act was re-written. The US was to follow us in a few short years. The gas pumps alone cost a small fortune to convert over or at least it seemed so at the time. And some things went metric in the US at first but then Reagan got elected and decided he was not going to spend the money and it all died there.

Many of us old fart still use both and when it comes to how tall you are and how much you weigh we seem to still use inches and pounds a lot. Meat lovers still tell the butcher they want a pound of whatever. But they get kilograms not pounds.

Having lived with both I can say with some certainty that the metric system is SO MUCH EASIER! Once you get used to it of course. There is no 16ths and 32nds and stuff like that. It's all based on 10 and multiples thereof.

Try baby steps. Get a set of metric sockets and wrenches at Harbour Freight and stop struggling with something that is a little too tight or a little too loose but sort of works.

Anyone convinced? Yeah... didn't think so.

I do like working in metric because of the easy measurements...tenths of mm, etc. It's easier to visualize a couple of millimeters than 3/16" of an inch. I've been tinkering with mechanical clocks and when using my digital caliper, I almost always use the metric scale to make my measurements.

But some (not very many) places in the US tried to convert and still have signs that show that. I was just on a road trip from Maine back to the Midwest. In New Hampshire (I believe), distances to exits on the interstate listed miles, and in smaller letters, also showed kilometers.

Bottom line - finally solved the nasty mysterious oil leak that took a few tries before zeroing in on OP unit - replaced oil pan gasket with real gasket & also replaced neutral switch - just grateful it wasn't rest main seal!

 

[brittrunyon]

Glad you solved your oil leak (for now) lol.
Neutral switches are often the culprit.
Ride On!

Road the Trans Lab in 2009 and while at the end of the road in Goose Bay, went into an Ace Hardware for a couple of items. I happened to notice that they had many inch spec fasteners and I asked a clerk about that. He told me that much of the stuff there that has to be fixed is inch spec, so it needs inch spec hardware. I also asked if they had any BSF or BSW English spec hardware and he told me I missed that by quite a few years.
