First time Attex owner needs help with rebuild.

You could send the t pins to me if wanted. Lol

You want it? i think it would work if it was the right size. It has more contact area with the channel. it seems like a good idea in theory.

The older brittle bodies are ABS and can be repaired with ABS melted into a goo with acetone and reinforced with cloth.....Or with special epoxy, and cloth makes that easier too.
The HDPE (high density polyethylene) was used in the newer bodies more mid to late 70's.....That is better repaired with the epoxy. I've had mixed results with plastic welding.

I seen that G/flex and was wondering if it was any good? Also anyone know where to get the axle gaskets for my Attex chief?

its ABS polyethen yaa cant match it..you gott to get crafty with general plastic and cloth resin....your hole...you should go about what i did it worked great with inginuity and some different materials of apllied techichs ile have to explain it in a email to ya personally

Thanks for the advice everyone. With the shifting levers removed I got the transmission to go into reverse with a screwdriver. So i made a replacement pin for the left side and put it back together and IT WORKS!!! Again thank you guys for all the great advice.

The next thing i need to do is fix the holes and small cracks in the tub. What's the best way to repair the plastic in these old machines? What kind of plastic is it?

[racerone3]

The T shaped pin in the pic above fits loosely in the hole. Do you think that's the reason it will not engage reverse? The hole measures 0.25 inches in diameter and the pin measures 0.24 inches diameter.

The T-pins had to be able to rotate as the shifter moved and that is why they have clearance. replace with a round pin that has a tight interference fit

[mfenmor]

I would change those T pins as they will not get any better with time.
Buy oversize hardened dowel pins, .002 over, McMaster-Carr has them, and a reamer to get an interference fit.
Press them in, not hammer in.

[dirtdobber]

The slack in the T pin may not be the problem, but .010" is a lot of clearance. It seems like if all was working properly it would get the shift collar close enough that the detent spring would pull it on into place. So, try this first - with the diamond out of the transmission, reach into the transmission and see if you can put it in reverse with a screwdriver.

If all works fine, put the diamond shifter back in and see if reverse will engage by hand (no linkage attached). Be careful not to drop that T pin down in the transmission. If it works fine by hand, then check to see if your linkage needs to be adjusted.

One other thing - It is possible to install the diamonds backwards which will keep it from working properly. You will notice the bore in the casing is offset with respect to the shift collar. When the diamond is installed, the pin is directly over the shift collar. If not, it's backwards.

That's an old T20. I can't tell you the year, but I've only seen a couple like that. You can replace the shifters with newer style or drive oversize pins into the existing shifters.

So i took my shifting levers out and found something that don't look right. take a look and tell me what you think.

hahaha nodody could months and months and thousands invested too bad i lossed all the interior engine compartment piping shots that detailed all the stainless loops and exaust connection science planned out it was brutal to do it but fachinating to see...the machibe became valued over 7000 dollars..then the bitch gott stolen!!!!! long story never could trace it...it was the coolest super chief in the country years ago richard of route 6x6 site the owner..had all the pics oploaded years ago on his site it bleww away people..all kinds of special mechanical adjustment tricks invented inside...i ran jet fuel octane mixture in it 52 miles per hour...im still not over to this day losing it..countless hours of inguienty to do what i did it was a mezmerizing machine.....if i EVER!!! found the ****er that stole it he would be so DEAD....

Sorry to hear that man, that sucks. I bet it was really cool.
