Bad t-20 pin need help

[micmac]

I discovered I had a bad pin on the bottom of my diamond shifter. Jp said that I can just replace the pin. I tried pulling it out with some pliers without luck. Anyone have any ideas how to remove it?

Also the bottom of the diamond shifter plunger is slightly damaged do you guys think I should replace the whole shifter or will it be OK?

Here is a picture of it:

The pin's a press fit, and if you can get a good enough bite on it with vice-grips, you should be able to turn it out. I've had reasonably good luck warming the cylinder with a propane torch if the pin doesn't come out easily. Put the vice-grips on the pin first to act as a heat sink (pull the o-ring off the cylinder first, of course).

Thanks Don I'll give that a try. What do you think about the shifter damage? I was thinking about smoothing it out with some fine sandpaper or emory cloth.

Thanks for the tip on the oring. That's something I would do!!! Whats that smell!!

I had a bad pin too...

I had a bad pin too and I ended up buying a new set they were only 25 bucks each, I had got one from route 6x6 and the pin was not the same length as the two I got from max, but one of the pins I got with my hustler when I bought it was home made they ground the pin to fit but it had two flat sides on it and it was wearing on the shift coller inside the tranny so I think it would be better to get new one's....

I agree, I would just give recreative a call and get a new one. Better safe then sorry plus you won't have to worry about it anymore. Amphibious Six-Wheel Drive All-Terrain Vehicles: MaxATVs - Call 1-800-255-2511

You know it Greasemonkey, but I'd have a hard time convincing the wife that i need one of those to keep from having to buy a $25 part

[GREASEMONKEY]

I have the same problem!

( Hey honey, I need this $500 equipment to make my own parts! It's gonna save us a bumch of money! What do ya think???)

The self induced Saga continues:

Before finding the bad pin I took the trans apart thinking I had a problem inside. While apart again (I had just put it back together to replace the O-rings) I broke one of the thrust washers. I gave a call to RI and the parts came yesterday. Well, what should have been a ten min job turned out to be 2 hours. Every time I put the cases together the clutch side wouldn't turn. I think I found the reason for it. I think the lower snap ring wasn't seated all the way in it's pocket so when I put the cases together it would get pinched.

During all the exploration I damaged some Orings on a band which was the original reason for opening up the transmission!!!

After some professional level swearing I just walked away, no cleanup, wrenches scattered, parts everywhere, sometimes you've got to just walk away.


I'm going to try and find some exact match O-rings locally today if not looks like I'll be calling RI again!


I did discover one thing that I'd like to pass on as a tip. I discovered you can assemble the inner drum /needle bearings/ washers and separator plate outside the transmission. Then If you pull a piece of dental floss tight around the bottom of the assembled unit you can lower it into the transmission case and then slip the dental floss out. Whola everything sits in place nicely.

I guess you know you can use vaseline for assy if that helps any

[liflod]

Looks like the pin has been riding on the shift drum and wearing it away. Aren't you using the spring loaded shifters on your machine ? If you are, you may need to put some stops on the diamonds to keep them from eating your pins.

Thanks liflod and Roger,

After taking a break from the machine I found some Orings and the trans went together without much problem today.

The Orings for the lateral plungers are #30 7/8 x 3/4 x 1/16 that was what was labeled on the package.

Another assembly tip: When putting the two cases together I threaded the break plunger bolt into the plunger on the non clutch side. That way I could hold everything in the case by holding the band tight.

Of course that never happened to me or anyone else Never been in a T20, but have been through more automatics than I can count. Of course the first time is the learning course, then it's supposed to be easier. Some day you'll advise someone, "oh yeah, I did that job, nothing to it"

Vaseline and Dental Floss

I have great respect for anybody who has enough self confidence to repair their own T-20 ,but if I had not read this thread and I walked into my buddies shop and saw on the shelf, right next to the red Locktite--DENTAL FLOSS and Vaseline I might have jumped to the wrong conclusion!

Phillip,

You can only imagine my wifes reaction when she was looking for the dental floss this morning!!
