Am I barking at the moon? Heat Riser Valve removal

MnBoy · May 20, 2019

So, I got the exhaust manifold off the '53 UB with no issues. Now, removing the heat riser valve from the manifold is another issue. Appears to be fused [rusted] on. Not real surprising as it has been together for some 66 years. Is it possible [practical] to keep trying to separate these parts? I have been using a large hammer with a cold chisel. I don't see any movement thus far. Probably better just to buy the replacement part. Your thoughts? Thanks.

Here is a picture of the manifold and heat riser valve.

If you're scrapping the manifold, you could cut the manifold apart to salvage the heat riser.

Cliff, thanks for the reply. That would likely do it, but sounds like a boat load of work as I do not have the right cutting tools to do the job. The manifold is built like a Sherman tank.

Well, the riser does not look too good itself. Replace both.

Thanks for the reply. I have a "heat riser valve" on order. Sometimes I feel that the vintage MM tractor is a big money pit, but it does things that no other machine I have can do....plus it is fun when it runs well.

You will be sorely disappointed if you only look at the $ side of owning an old tractor.

You are spot on. My interest in having a MM is that both my dad and grandpa worked at MM [Lake Street plant in Mpls] for a long time. Still have my grandpa's retirement ring from MM after some 35 years of service. So, it is sentimental and you can't really put a price on that.
