Guy's thanks for the info on the Fuel Bowl w/shutoff, I ordered one for my 122, it will be nice to not have the $4 a gallon gas leak!
Graeme, thanks for the great information on Stainless Steel.
Here’s possibly some more useless information, directly from Cliff Klaven…
There are 2 basic type of Stainless Steel used in the Hardware/Fastener Industry. 316 SS and 304 SS, if a person had a 304(most common) bolt and they were tightening a 304 nut onto it, the 2 MAY gall together. Meaning they MAY weld themselves together, no way of removing the nut or finishing the job of tightening this nut. This would be most common in a manufacturing application where an assembler on a line could install this several times or maybe do this for a couple hours, then all of a sudden one will gall. It has to do with heat buildup between the surfaces, it can happen whether the nut is spun slow or fast. Fast would heat up faster due to speed, but turning slow would trap the little heat build up in the threads between the nut and bolt.
Stainless does not gall to steel, it galls to the same style stainless. It has to do with the low carbon of Stainless Steel as Graeme said.
In an application where Stainless is needed, a 316 nut should be used with a 304 bolt or screw. Or 304 Bolt or screw is used with a Standard steel nut. Check out all the road signs in the state of Minnesota, they should be using 304 Stainless Bolts and Standard Steel Nylock Nuts. 304 SS is the lower grade Stainless, less expensive.
Also I would not use lock washers on Cub Cadets, I would use the Standard Steel Nylock Nuts. Lock washers will vibrate loose on a high vibration application such as a Cub with a Kohler.
18-8 SS is the same as garden variety 304 Stainless, 316 SS is stronger. Although I do believe 18-8 or 304 is as strong as Grade 5 hardware.
Also the standard hardware that is bought at a hardware store, Menards or Fleet Farm barely(or maybe not) meets the Grade 2 Standard. With today’s steel prices I would expect the quality of these fasteners at Menard’s and Fleet Farm to decrease, yet I am sure the price will only increase…
There, whew, that was a mouthful… Let me know if it makes sense – maybe I learned something from selling fasteners.
