I'm in the process of installing an original equipment Vickers external valve on my 550.( I have the large, very complete factory manual and Larry's email by the way "old"). The problem is the two pipe plugs that need to be removed won't budge. My question is,would it be safe to use some heat on and around these plugs with out damaging anything inside the housing?

There are "O" ring seals in the pump heat not suggested. A heavy vise and pipe wrench should work as there is no telling what thread sealant was used.

Thanks,but I think you misunderstood.The plug in question is 1/8 pipe thread(to small for pipe wrench)and the housing I refered to is the tractor hydraulic unit that is also the transmission cover and still in place.I got a Big Vise but just couldn't lift the whole tractor up into it.Hope you can laugh out loud as I did when envisioning this.Thanks again for the reply.

I got the 1/4 pipe one out,but the small one even with a little heat and the wrench set up I explained to J. Schwiebert hasn't worked. The small square head is about to twist off.I may try to tig weld a hex nut to what remains or drill it out,but for now I'm putting it back,repainting the cleaned surface as I have more important fish to fry and need the tractor.

The mexican assembled plastic/aluminum radiator in low mileage F 250 diesel just came apart(Built Ford Tough)I think not.

Regarding the manual,it's a copy of the factory manual,covers (if I'm not mistaken) 66 thru 880.Hundreds of pages. Cost 150 dollars plus shipping(hard binder included)from the museum in Charles City Iowa.It's dollars well spent in my opinion.

Take a good pipe wrench put some muscle on it,let someone tap on the plug with a flat punch while you pull, some PB BLASTER penetrating oil might help. If this does not work I do not think heat will hurt as long as you keep oil in the resivor. After you get one plug loose run tractor a minute to circulate hot oil inside,then do other plug. this is what I would try

I'd try tapping on them with a hammer not hard of course, doing that works well on brake bleeders and a lot of other pipe fittings. And I don't alway refer people to Larry, I only do that when I think it will really help a person, which is the only reason I ever answer any of these question on this forum. I just like to help people with there problems.

I only answer that way when I don't know that you know and when its something like will this cam shaft fit this other engine. I would also like to know about the bees wax thing I have a good guess at it but not sure right now. It may be like the hot oil trick, Which is heating oil up real hot and pouring it on to the thing that won't move for you. Which by the way you could try.
I've even heard of putting boiling diesel in to and engine to un stick them.

When I worked on the engine side and we did block schools many times we could not get the pipe plugs out of the oil galleries. We would then heat the area around the plug to a dull red which also heated the plug. We would then apply bees wax. The theory is the expansion would allow the wax to melt and be pulled in the threads which then acted like a lubricant. Sometimes we had to do it twice, but I would say we had over 80% sucess rate.

Thanks,I guessed it was as you explained.I got the larger of the two loose(1/4 pipe thread)without heat.I used a 3/8drive 5/16 6point socket,put the sq.drive end on the plug and a5/16 hex adapter to another 5/16 socket and long handled ratchet.I tried a similar set up using 1/4 drive on the 1/8 pipe plug to no avail,being careful as to not twist it off.Next step will be a little heat and wax.Thanks again for the reply.

There were times when I needed to check the pressure to the power steering on 1600 & 1800 models and when I used my quarter inch drive I would use a flex handle and lock a vise grip on the pivot point and then use both hands (two hands for beginners you know) I found I did not break any more flex handles and I did not slip off as much either for what it is worth. Good Luck
