Low-cost bypass filter

Hi,

Here are a few thoughts from last weekend:

As a low-cost alternative to a bypass filter or fine filter (less than 5-7 μm), a fuel filter without a drain plug (made of plastic) can be used.
For example, these could be models WK723, WK731, etc., or, if you need a larger size, WK962/4.

The filter is mounted on a universal filter head with M14x1.5 connections.

It's important not to eliminate the throttle, as this would result in too much oil pressure being lost through the bypass. In this case, an "OUT" screw from a Bosch VE pump with a 0.55mm bore would be suitable. Since it has a 12x1.5 thread, an adapter from 14x1.5 to 12x1.5 is required here.

The entire system is connected, for example, using hollow screws and ring terminals, with low-pressure hydraulic hose (20-30 bar), ideally as thin as possible (6mm).

Hm, what's the point of all this ? No more oil changes?

The ways of the Lord are mysterious. Hopefully, nothing bad happened to him.

Hi,

There are engines that only have an oil filter screen, which results in relatively short oil change intervals and, consequently, higher wear. Here, it is often cheaper and easier to use a bypass filter .

Hi!

Where are we right now?

Lawnmowers, pre-war tractors, plate compactors?

For example, the VW Beetle and the original Fiat 500 only have a very basic oil filter.

Generators, for example... where an oil change is often quite tedious, especially in soundproofed versions .
