Has anyone had success in replacing just the rubber or “tire” on the roller? It seems the biggest challenge for me is that the pinch roller in my V-1010 is an all one piece unit with a plastic hub and shaft so sourcing just the roller is not possible. There are websites selling just the “tire”, but I guess that it may be a complete fluke to get an exact inner diameter size. See pic below

Hi Netlist,
I looked on their website yesterday, have reached out and received a response from Marian who believed they have the correct diameter and width roller, but I was asked if my pinch roller has the plastic shaft or through hole. I replied providing the pic of the one installed in my deck but have not as of yet heard back. The pictures of the rollers on their website only show the “non shaft” type which is why I’m pondering the tire only possibility.

Thought to pass on this additional website that has replacement parts for many brands of cassette players. Unfortunately the pinch roller I need is currently out of stock. The manufacture date says 2023 so I hope they will indeed continue to offer parts for cassette players. They also carry pinch roller shafts. I’ve signed up to get notified when they are back in stock. They also have an eBay store but only seem to offer capstan belts and not the rollers.

Not sure what the pinch roller shafts are intended for. They're typically a press fit into the head block, and are hard-chromed so last forever. You might have some luck mic'ing the factory roller, diameter and height, and it's shaft diameter, and maybe a supplier can work from that. Probably a limited number of common sizes for single roller machines.
All good fortune,
Chris

I’m thinking that in a case like mine where the pinch roller/shaft is all one piece that it offers the possibility of a replacement pinch roller that fits the dimensions needed but does not have the shaft built in? This seems like it may be my only option.

Well, the pinch roller's central shaft is mounted to a spring loaded rocker arm, and maybe with this plastic rocker arm the shaft must be pressed out (and later, pressed back in) to exchange the pinch roller? I've never seen one like that, so you learn something new every day, if you're lucky.
Much thanks,
Chris

I’ve removed the pinch roller from my cassette deck and measured it with digital callipers. The outside diameter is 12.79mm, the rubber width is 7.01mm, and the hub width is 7.91mm. The shaft is 1.96mm diameter, and 11.77mm long.
In looking for a replacement I’ve found one that is 13mm diameter, with 8mm hub, but the width of the rubber is 6.3mm. How critical is the width of the rubber? Will the 0.7mm smaller width make that much of a difference?

Isopropyl alcohol is a fairly gentle cleaning product, and generally the 'go to' fluid. Metho. really works just as well.
It is when rubber is at the stage of perishing that solvents can cause 'stickiness' and should be avoided.
If you 'refurbish' a pinch-roller with Wet&Dry, you should start to use solvents very sparingly, or water diluted.
PS.
You should see what Trichloroethylene can do for a 'never cleaned' roller > it is quite astonishing 🙂

When you find a replacement, if it has a plastic hub, you may have to sand down the sides of the hub to fit the holder...did that a lot but at least the rubber is new
I had also thought about that, I guess I will see if any adjustments need to be made on the new roller. Any insite to share about the new rubber width being slightly narrower? The possible roller replacement I’ve found has rubber that is 6.3mm wide, and the original is 7mm wide. Will this be an issue? I’m “thinking that as long as the rubber width is wider than the tape (and the roller is centred) that it “should” be ok. Thoughts?

This is actually one of the places that I may be sourcing the pinch roller from. I was in contact with Marian before removing the existing pinch roller. He asked me to confirm what size mine was.
The rubber width is not critical as long as the tape is flat and is straight running.
If you find, particularly at the start of playing a tape, that the tape is drifting towards the edge of the pinch roller rubber, you must check the play take up tension on the take up reel. If it is too strong you will have chewing tapes issue as its tension overcomes the rubber pinch roller grip at the beginning of play. Very common fault and people keep changing pinch rollers buts its the play take up clutch that is causing the issue.
To check correctly a torque tension tape should be used, hard to get these days though, I still have my valuable Sony one!
If no torque tension tape available just use your finger and thumb on the take reel in play mode, a light to moderate pressure should make the take up reel stop, if you require strong pressure your take up reel tension it too high and the clutch will require a service. If a very light pressure makes it stop your reel idle tyre is probably slipping and will require replacement. Correct Play torque tensions are specified in the service manuals.
But note in play mode without a tape inserted you will most likely have to overcome the auto stop action, either opto or mechanical type, by turning the reel tables, otherwise the deck will keep auto stopping as your checking the tension...also you will have overcome the tape insert detect switch...so much fun

Update on my tape deck… IT LIVES AGAIN!!! I reached out to FixYourAudio.com and ordered two new pinch rollers. It took almost 3 weeks to get me up and running but it was worth the wait.
The removal and replacement in my case was actually very easy. Whether by design or not by Teac, the pinch roller and arm swing/sit very low when the unit is stopped so the roller just pops out and can be reinstalled without removing the capstan.
Thank you to everyone that offered help and advice, it is truly appreciated!

I did order a new capstan drive belt at the same time as the pinch roller. I’ve yet to install it, that’s a project for another day. I’ll have to go through the service manual and see which other/how many additional belts there are (I think there’s only one other) and order those as well. As far as I know I’m the second owner of the unit. It was purchased about 25 years ago from my best friends Father who was meticulous about the care of his equipment.
At the moment it seems to play my tapes very well without any noticeable speed fluctuations. With that said, I don’t have any equipment to test wow and flutter.
