Replace the pinch roller and if there is an internal idler, replace that too. >Those are wear items that just need to be done every five or ten years. >--scott

Scott,
Where are these parts available? Thanks. Chuck
Terry's Rubber Rollers should be willing to rebuild the existing ones if
you don't have a source for spares. Russell Industries may have spares
for belts and internal idlers on the shelf.
I have a circa 1968 Sony 250A that I have been using to convert my original=

Okay, so you have a machine that has maybe fifty years of deferred maintenance.Actually, probably about 10 years on the Sony, but I get your point. When I got started
When was the last time it got a clean and lube? Forty years ago maybe?
You need to go through the complete lubrication procedure in the manual,
and it's going to be harder than it would normally be because there is
crusty varnished-up stuff all over everything. Everything comes apart,
gets oiled or greased, goes back together. All rubber parts get replaced,
and all of the connectors needs to be cleaned with DeOxit or Cramolin.
Then you do the alignment and see what else is wrong. Which will almost certainly involve capacitor replacement.
I don't think the TEAC had much care before I found it, but it did work. I cleanedI also want to add a bit on using other recorders to play old tapes.

Sure, it could be a head alignment issue. But it might also be that you are trying to play back half-track tapes on a quarter-track machine. Almost certainly it has bad electrolytics throughout the electronics and all of the contacts are dirty. When you put the alignment tape on the thing it will likely become clear what is going on. There is fifty years worth of maintenance on this machine that hasn't been done and now you need to do it all at once.
Budget maybe ten hours for a tech who knows what he is doing to tear one of these things down and get it meet original specs. But please be aware that original specs aren't really all that good... it really is not worth the time to work on single-motor consumer machines.Good advice. Fortunately none of the music is irreplaceable original recordings.

on this project I was more worried about the tapes than the reel-to-reall, but turns out the old machines are more in need of attention. What "manual" do
you mean? I have the original owner's manual which includes routine lubrication
and cleaning instructions, but not much detail about other things. Are there detailed
repair manuals and where would I find them?

I have not tried aligning the tape heads, but about 25 years ago I had a local
repair place, now long gone, do an overhaul. What kind of equipment does it require and where can I find alignment tapes?

and oiled it recently, but that's all. I doubt I have any half-track tapes kicking
around; but some tapes play quite differently on the two machines,
with the TEAC being weaker on the right channel. Others seem to play
the same on both. If I can get both machines up and running, I may try
to figure out what's going on. I recorded some on new tapes, some on used tapes, and bought some used tapes and saved the music on them.

Ok. Y friends,where the heck do I get rubber wheels and belts and whatever turns theserereels around anyway??

Isn’t there anyone who makes reel to reel affordable tape machines anymore??
Hi again gents, I got a Sony TC-252 reel to reel with speakers . Was listening to some of my old 1970's 4 track studio hits. As the tape went through a few songs it got slower and slower. I don't think it's sludge on the heads from the tape. It'sMaxell and is just fine. My father in law gave me this machine and it did the same thing with one of his tapes. It might start 1/2 step flat then after about 8 songs it's 2 steps flat.
Is this because of a loose belt? Thanks if you can help. Glenn.
