I have a broken roll pin or spring pin in a blind hole in a payloader trany.How would you remove or drill it ? Drilling from the back side is not an option.It has to be replaced as it keeps a sleeve with oil ports in alignment. thanks for any help

Hi John, The grease trick will work. wrap a heavy rag around the top of the hole. The grease will come out in a hurry. The pin will scoot out and side cutters should help it out.

just an idea: can you get a small "E-Z" out tool in there? if so maybe you can work it out like a broken off bolt. also if you have a left handed drill bit, it may catch enough to turn the roll pin out. only other idea would be like someone else said: grind it out with a dremel or air die grinder.

"Norseman" makes "hard steel drills" with a strait flute shank and carbide cutting tip in a variety of sizes and at very reasonable prices, just got a 1/2" one a couple weeks back for around 15 bucks. These are rated for drilling steel to 65r or so and do work very well. Slow speed operation, easy on the feed pressure and dry cut. I have drilled numerous hardened set screws and roll pins myself with these. Drilling roll pins is a bit tricky because of the split in one side which the bit will try to grab onto. Using a light feed pressure usually eliminates the problem.

The roll pin is only 1/4 inch so there is not alot of space to work in,less than 1/2 inch in depth though. might try a concrete bit .that dremel bit may work too.Not going to rush as the housing could be worth several grand.The 2ft shaft that enters it is $7200 cnd.thanks for all the advice and will keep you posted.John

have you tried a die grinder with a tungeston carbide burr to grind it out ? i have a electric dremel tool that i have used on some pretty hard things as well as a air die grinder . the dremel would probably be best if he pin is small as you can get much smaller burrs .would probably be best to only remove only enough of the pin to weaken it so you can work it out

IF the spring pin is not hard up against the bottom of the blind hole and IF the circumferential gap in the pin is near zero or can be blocked up in some way, I would try the following: 1) obtain or make a steel drift with a running fit with the ID of the spring pin, 2) Fill the cavity of the spring pin completely with a heavy grease, 3) Insert drift in spring pin and rap hard with hammer. Watch your eyes! The idea is to create a large hydraulic pressure at the base of the spring pin...hopefully enough to move it out at least a little at a time.

Just a wild thought. The method has worked for me with bronze brgs in blind holes. No circumferential gap to have to deal with there though.

You didn't say how big or how deep the roll pin is, but on larger rollpins that aren't excessivly deep, I have used a die grinder with a small deburing bit and cut another slot opposite the existing one and pull the two pieces out. This, however does not work on the coiled up type of rollpin. Good luck!

If is a spring roll pin it is made of a very hard material drilling may be a problem if it is big enough you may tap threads on the inside of it and thread a screw with a allen head on it and pull it out. GOOD LUCK

A machine shop with a EDM machine can burn the pin out to the bottom and the hole will be close enough to the same size that you can use the same size spring pin.

if you have room to use a punch they make regular splt pin punches don,t use anything else they have like a ball on end will drive them out we used a lot of them in power plant drilling is not good as they are hard and drill will wander and cut softer material along side any good tool supply should handle them and try for america made

Got the roll pin out. Went to a local machine shop with it.Young owner/welder/machinest placed a small rod with a small homemade slidehammer near the edge and welded the other side with very small special rod the only arcs staight down. Two raps with the slidehammer removed it.No damage to the hole. A job very well done. p.s. there was no charge as he would like to use the payloader in the spring
