How to replace valve guide, Case 1370.

Henrik Jansson · Mar 2, 2015

Hi!
How should I do to get the old valve guide out and get the new one in, on a Case 1370.
Shell i press the guide up or down when I remove it?
Shall I use a hammer or a hydraulic press?
Is there any risk that the cylinder head cracks?

Hello Henrick. I service manual says to press them out from bowl side and then press them in from the same side, using an arbor that fits a pilot in the hole and has a diameter just smaller than the guide itself. Measure how far the one that is in the head pokes out now and install the new one to the same height. Do not install higher than what is already there or you may have valve spring retainer issues. If anything a bit shorter, wont hurt.

Ok.. thanks.
I have some difficulties to understand this in english.
"bowl" side? Is that the bottom?

Lets say like this instead:
If the cylinder head is in the same position as it is when it sits on the engine, shall I press the guides up or down?
And, in the same position, shall I press the new guides up or down when I install them?

Shall I use a hammer or a hydraulic press? Do they sit hard?
Is there any risk I crack the cylinder head?

Henrick, With the head setting on the tractor, you would press from the side the head gasket mates to, towards the side that has the rocker arms and is covered by the valve cover. The bowl is what is uncovered when the valve is removed.

I would recommend using a press. With a press there is less likely hood the you would make a bad job. They do set in the head pretty tight, that is why the press is the best way.

I used to like to put the new guides in a small pan, then spray them with refrigerant till there was some liquid refrigerant in the pan (that indicated that the refrigerant was as cold as it was going to get. Then press them ih as quickly as possible. Some times I would spray the refrigerant down the guide for a bit B4 removing the guides, that cools and shrinks them a little to help in removal. On the old Chrysler flathead sixes ,I would spray the valve seats, hit them with an old chisel causing them to crack. Remove the pieces - cool the new seats in the refrigerant and usually they would fall in place then a tap with a block of aluminum and they were done.
