I seem to remember a few instances where a through bolt had a different nut size from the head size. Some farm equipment. I think the reason was that you didn't need two wrenches of the same size to hold one end and turn the other. That helped keep your tool set on the equipment a little smaller, I guess. I've encountered that a few other times in my life, as well. Different bolt head and nut sizes. But, I can't remember the exact items that had that.
Yes, fair comment!
But I grew up with British cars, almost all of which just needed standard tools. Still work on a lot.
With the switch to cartridge oil filters, I acquired a Facom oil filter wrench, (below - superb tool) with a stainless strap that’s able to handle every cartridge filter I’ve ever encountered, which is most British or Euro cars since.
I know that many makers have switched back to separate housings, and special tools, but I don’t see many Chevy’s and Jeeps in my part of the world (and I’m pretty sure the last Suburu I saw had a cartridge filter), so it’s only really BMW’s (and Mini’s) that I find myself needing these big sockets for.
If it’s a single purpose tool, it’s a “special”!Not to beat a dead horse, but . . . 'special tool' ^^^^
That Facom strap wrench does look handy, I have the circular kind in two sizes to fit various diameter spin on filters. And I had to buy specific fluted cup filters for some spin-on's because they're deep in a hole where a strap wrench won't fit. Then of course various filter housing sockets for top-side cartridge filters. Yes, I have found myself with many "special tools" for oil filters.
9mm for Solex carb on older VWs
I used a 9mm today on a Mopar 2.7l cooling system bleed screw................
Meh. I own nothing in 3/4" drive and have had a 36mm BMW oil filter socket for decades. I mean you can find them for less than a tenner delivered to your door. Same as any oil filter strap wrench, plier, or cup, if you DIY, you're going to need something. Plus, one can torque the filter cap correctly with 3/8" drive.
Nice!
I love it when the filters are on top of the engine.
We have three subarus, all have fumoto valves. Tractors and mowers to. Haven’t had oil on my hands in a long time!
Yep. Fumoto valve on both cars (BMW, Jeep) and both have topside filters too. Easy no mess oil changes
On my Grand Cherokee I don't need to jack it up to get to the oil pan drain. Although I do need to lift our E46, it gives me a chance to inspect the front end so I don't mind so much. I never did trust those oil extractors to do a thorough jib, maybe I'm just stuck in my ways. Going to yell at clouds now . . .
Suzuki vehicles use 9mm nuts on the studs for the fan clutch.
Did you try a 19/32" socket?
15mm is Chevy drain plugs IIRC. I forget what 18mm is used for, but I know I had to buy one several years ago. There's a bunch of 7mm on (actually under) Fords
[checks $6 Walmart wrench set...] Nope, doesn't have one.
The missing 16mm is the one that always gets me...........................
CTS front caliper bolts for one, they seem to use 18mm alot for that, I've also seen them on struts.
Ford and GM use a lot of 7mm for interior trim.
I have a pedal wrench like this. Has the open end for the pedals, and a socket end for wheel nuts. Came with my first bike "tool kit" I bought last century, still use it. A 15mm wrench from a normal wrench set is too short and sometimes too thick to deal with pedals. I know because I have one. If you can remove it with those, you likely haven't tightened it enough.
TOPTUL sells an identical tool. Likely a Facom copy as Rotar makes wrenches for Facom. https://www.toptul.com/en/product-324194/Metal-Strap-Oil-Filter-Wrench.html I bought a box of these and I did manage to sell them but personally I found them not that useful compared to cup wrenches. Where do you have that kind of space on a modern car? Maybe they are useful on farm machinery of something like that but they were useless on my Hyundai as it didn't fit where I needed it to go. Also, it's not like a pliers type oil filter wrench that can be used at an angle. These must be absolutely perpendicular to the filter during use.
To get you back into the store… to buy the missing sizes, that you… all of a sudden, need so badly.
actually even on all metric cars, sometimes I can find a bolt that fits better in an SAE socket and I will use the SAE one.
All SAE sets skip. That stupid system can have 64 as denominator and it is just hard to spot the missing one, like 7/64 or 9/64. I have never seen a set start from 4/64 to 64/64.
A nice feature of the fractional system is the jumps can get larger as the fastener gets larger. So the sizes jump by a 32nd then by 16ths then 8ths. With 1mm jumps it would make sense to skip sizes but which ones? Toyota skips 13, 15 and 16. Germans use 13s. Shimano and the bike industry uses 15mm. This is less an issue with things built using SAE sizing. Of course SAE has a whole host of it's own problems...
