Danny152 Posted September 7 Share Posted September 7 (edited) I have been told there is a special UNC threaded tool needed to remove the dowel type pin keeping the torsion bars in on a CVRT. Does anyone they have spare for sale, or provide drawing, photos etc so I can make one? Thanks Dan Edited September 7 by Danny152 Spelling Quote Link to comment Share on other sites More sharing options...
teletech Posted September 8 Share Posted September 8 (edited) Here's a picture of what I used to pull the pin. It consisted of: short threaded rod in #10-32(or#10/24, but I think it's 32TPI), thread adapter to tie the allthread together., #10-32 allthread rod, deep socket (5-16"?), thick washer so the nut won't slip into the socket, #10-32 nut. Actually, looking at it now, it night be the case the thread adapter is actually a nut to lock the allthread into the dowl. I'll see if I find the tool on the shelf and document it better, but it did work. I had to replace the allthread a time or two since it can take a lot of force to remove those pins and I used what was on hand rather than buying high-strength rod to start.. It helps if you have someone wiggle the bar while you remove the nut. I recall there's a grubscrew over the pin you have to remove first.

Danny152 Posted September 9 Author Share Posted September 9 Great, that is really helpful! It looks quite a device considering it just pulls on something, 😂 Quote Link to comment Share on other sites More sharing options...
teletech Posted September 9 Share Posted September 9 basically it's a threaded rod to pull out the pin, but since the pins have been there a while, it takes some real force to do that, so you have to provide something for them to pull against. One could try using a slide-hammer, but I found slowly-increasing force valuable for overcoming the gelled grease consistency of crud in there. This thread reminds me that I need to make some replacement pins to replace the ones that were damaged. Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted September 10 Share Posted September 10 Just hope you don't find that the proper pins have been replaced by plain rod which then needs drilling out from beneath the hull like I have! Quote Link to comment Share on other sites More sharing options...

Oh, OUCH. That's gotta hurt. I had to drill out a couple of mine, but at least they were the correct material and so had effectively a really good pilot hole.

Danny152 Posted September 10 Author Share Posted September 10 It sounds daunting lol! But will get the tool made, just to confirm the rod is 32 TPI? Sorry to ask again. Will get one made. I am sure there will be some more questions to follow! Thanks Quote Link to comment Share on other sites More sharing options...
Grasshopper Posted Wednesday at 07:49 AM Share Posted Wednesday at 07:49 AM (edited) Another problem can be if you have a seized radial arm bush. When non-destructive methods, special tools and heat failed, we had to resort to a telehandler. Not recommended, but did the job!
