Mounting pressure washer pump

[Donald]

I bought a used Craftsman pressure washer with engine and frame for $35 I think. Nothing else. And I have a new AR pump I have had on the shelf for 10 years. Engine runs great.

Horizontal shaft. Standard 4 hole mounting. 5/16 fine thread.

The way the pump housing is cast the only thing I can use is a cap bolt for an Allen wrench. Not even room for a standard split lock washer.

Do they sell lock washers where the outside diameter is the same diameter as that of the head of a cap bolt?

Or Locktite?

Or keep my eye on the bolts?

Now will Ace hardware have them?

loctite seems easy mode if you cant find something at ace.

Cat pump sells a 10ml locitite for only 1000% markup so I dont see an issue with using regular loctite.

So they are called high-hat split ring lock washers. Nothing local I could find.

Bolt Depot had them for $0.11 each plus $4 in shipping. While $4.50 seems high for 4 washers, it probably the same as some Locktite or gas used to find them locally if I even could.

The local ACE Hardware store than has tons of nuts & bolts in the usual drawers did not have these.

Bolt Depot did not require me to buy a bag of 50.
