Clutch pedal movement

While having a look at the brake and clutch pedal firewall seal (or what used to be) I noticed a lot of sideways movement or slop in the clutch pedal. Checking the parts catalogue indicates a pedal bushing - part number 71 91C R1. Does anybody know where this bushing can be obtained or can cross reference it to another bushing or is there another cure for this problem ? It won't take the truck off the road but nice to be fixed.

Re: Clutch pedal movement

I was not able to find a proper bushing, so I made one out of DELRIN. If you do not have a lathe, maybe you know someone who can make one for you. Another possibility is to look for bushings in a bearing catalogue. Call a bearing supply with some numbers. You will need a vernier caliper. Bushings have an inside and an outside measurement. Your pedal pivot opening may need to be reamed straight, this will change the fit of an OEM part. I had to chuck the pedal pivot in my big lathe and clean it up. New parts on work parts usually does not work well.
I hope the pictures help a little.

I went here for bushing stock for my pedals.

Re: Clutch pedal movement

It may or may not make a difference to your search, but that bushing number is 71 910 R1

Re: Clutch pedal movement

Thank you all for your replies and suggestions. I had resigned myself to not being able to source a replacement bushing, having done some online research so your replies and photos have now firmed up my plans.

Re: Clutch pedal movement

I made mine out of Delrin also. As said, it is usually not a simple remove/replace with a new bushing. Required new thrust washers and swivel joint for the clutch shaft.

Re: Clutch pedal movement

Thanks, Bill. I am nearly ready to attack this job - are you able to tell me the part numbers you refer to when you talk of "thrust washers and swivel joint" so I can be more prepared when I remove the clutch pedal unit? I have the parts diagram but nothing is shown in those terms.

Re: Clutch pedal movement

Sorry no numbers. I made a washer to fit (see left side of photo). I used an off-the-shelf ball socket from Tractor Supply. I had to face off each side to get the correct width and weld it to a plate for mounting. I may have bored it to fit the shaft, but I don't remember. Hard to see it in the photo. End of the clutch shaft on the side of the bell housing.

Re: Clutch pedal movement

I used Ash Bearing for the bushing as well, but don't recall the part number. I do remember it was too long and I had to cut it to fit.

That clutch shaft bearing had me stumped for a bit. I was working on fabbing one until I found out its the same as used in the early Scouts. The Scouts use 2 on a long shaft.
