How do you remove the valve guides to replace them?

Postby Wrose2 » Fri Jul 15, 2016 4:29 pm

Ok. I've removed the valves, Springs, and keepers. Now I'm trying to get the valve guides out so I can replace them with new ones. Question is how do you get them out?

Short answer. Old valve guides are pressed out and new guides pressed in.
I have an excuse. CRS.

Hi,
Here is a page from the Cub parts book. The valve guides are number 7 in the pic.
Like Eugene said, pressing them out at a shop is probably the easy way, but you have to remove the engine and have it at the shop first.
There was a post some time back about someone replacing them without removing the engine, not sure how he did it. :)

guides can be driven out easily, they need to be pressed back in carefully

Service manual, page 1-21, has a picture of valve guide installation measurement.

The measurement is 1 3/32" from top of block to valve guide center line. You should take a look at the parts manual to see how the measurement is taken.

I was able to get them out using a 5/16 grade 8 bolt with large washers on top and a nut under the guide. Tightened the nut and bolt which pulled them up and out. Now we'll see if I can get the new ones in.

Has anyone tried putting the guides in a cooler with dry ice prior to inserting them?

It is about 100 degrees F colder than a typical home freezer. I have been thinking about trying this just wondering if anyone has tried it.

I've been told that dry ice works well. I plan on getting some and trying it when I reinstall the new ones. I'll let you know how it works

Here are pictures of a simple tool I made to pull the guides.

I've got a question about installing the guides. The service manual is clear about the depth from the surface of the block to the center of the guide -- measured vertically from the block -- should be 1 3/32". My old guides measure 15/16" very consistently. Could they simply have been installed incorrectly? Here is a picture of what the old guides look like installed.

They clearly did not get pressed down any where near the bottom of the guide cavity. They are at least 1/8" proud of the the bottom of the cavity. It seem like if I press the new guides in to 1 3/32" the top of the guide will be very near the bottom of the guide cavity. Is this correct?
