Re: PS pump check valves removal problem

[Phil Rose <pjrose@servtech.com>]

Igor,
I've been looking for a set like that for a while. Seems I can find all
kinds of 1/4" hex-drive bits (torx, Phillips, square...) but not metric
Allens. I'll start looking at Makita suppliers for it.

That type of setup is nice because you can also use the bits with a 1/4"
sq. drive socket in places where a 3/8" drive can't fit. For example--the
"water collector pipe" (manifold) that runs along the side of the cyl. head
in my 3B engine. It's the one that the afterrun switch and multifunction
sensor are screwed into. One of the pipe's flanges has started to leak
coolant and the 5 mm Allen-head bolts that attach it to the cyl. head are
in very tight places--only reached by 1/4" drive. Oh, and its a component
that's almost impossible to work on unless the PS pump is first removed. So
I'm in the "kill two birds with one stone" mode, I hope. Well, kill or be
killed.

Back I go--to the hardware stores on Monday.

Thanks again,

Phil
