Valve Guide Bolt Removal

Jimmy Z · 07-10-2008, 08:48 PM

Right... I have come across a KP2.. and got the parts for refurbing it from PPS.

I have it all stripped down EXCEPT the Valve Guide nut. Before you say it... yes, I've read the stickies, yes I've done a search of the site.

Problem I have, the damned thing is seized in solid. Tried brute force, tried pentrating spray. One thing I haven't tried (hence reason for posting before I go and do myself or it a serious mischief... ) is Heat.

Obviously, the amount of solder / etc holding everything together is a concern. BUT is heat an option? I've already knackered one removal tool (the head is twisted out of proportion... and I really don't fancy having to order yet another one from PPS.

Help?

Melting point of Brass: 900°C to 940°C
Melting point of Aluminium 660.25 °C

A Propane torch can give off up to 1995 °C

I would try and dunk it in hot or boiling water first.

:edit:
Wait ... what exactly do you mean with valve guide bolt?

Do you mean the valve retaining nut?

Have you try'd really long handles on the valve tool? Thats what has worked for me in the past before...

Hot water is my suggestion. Or if your wife has a hair dryer that puts out some good heat.

damn. i've had some tight ones before but never have seen it tear the tool up like that. try some heat for sure.

who made that tool???

I'm surprised the valve retaining nut didn't give out first... it is softer.

Are you turning it the right way?
