Repair shop?

I would take the engine cover off and get in the back seat and let someone else drive and look down in the engine compartment to see if everything looks ok and try to pin point where the sound is coming from.Just a suggestion.

Yes everything is turning fine everything seems fine going straight Just that loud pop and grind when I turn right

where in NC are you located? If Statesville (Just north of Charlotte) is a doable day trip, bring it by Saturday or Sunday afternoon... We can take a drive, find a problem, Try to fix it... let me know if you want to swing by. 704-902-3734....... Brian

Ok so you have splined axles so its not axle bolts. If possible I would put the vehicle on sturdy blocks and see if you can replicate the sound and determine if the source is outside the transmission ie chains and sprockets. Or sit in the back seat with the floorboards and engine cover off and have a buddy drive to locate the noise. Be careful of the chains!!
Silly question but the chains are adjusted properly correct? Hopefully someone will chime in about the engine as I'm not an engine expert (or even close)

Might have found the problem today. One of the bolts that holds the transmission in place is missing so when I pull the right stick the whole transmission moves a little. I will post a pic as soon as I can figure out how to post one using a iPad.

Now that I am a lot deeper into this thing both bolt that hold the transmission on the right side are gone . Is this a common problem?

[hydromike]

I wouldn't say it's all that "common" on a Max IV, but as a regular maintenance item it's a good idea to check all of the nuts and bolts on the machine. A side effect of the bolts coming loose on the T-20s (on almost any T-20 machine) is that the bolt holes in the aluminum case halves tend to get wallowed out as the machine is driven and the transmission jostles around. It's going to be a bit more of a pain, but it's important to verify that the holes in the transmission are still in useable shape, and that you're going to be able to safely tighten up the bolts when you reinstall them.

If you're lucky enough that the holes are OK, it's a good idea to put some lockwashers (if they're not present) on the bolts, some locktite in the hole, or even safety wire the bolts together on that side. The transmission on the Max IV (as you know) is a bit harder to access, but all the work will be a security investment in the long run. Congrats on tackling the job yourself! We knew you could do it.

EDIT::

And here's the tutorial on posting pictures. I don't know if any of it is irrelevent as far as the iPad is concerned.

well i got it out and this is what it looks like

[micmac]

Not good unfortunately. They looked to be wallowed out like Hydromike said. I know there is a thread on here somewhere about repairing the case holes but can't find it. Just wanted to let you know that it will need to be addressed before putting it back into the machine. Congrats for tackling it yourself now you'll have a greater understand of the machine. I highly recommend cleaning up the t-20 case and adjusting it while it's out of the machine, also a fluid replacement too ATF AND LIMITED SLIP FRICTION MODIFIER ONLY NO GEAR OIL!!! I'd also clean the interior of the machine while the engine and t-20 are out. Sounds like this machine wasn't taken care of so you probably will find some other stuff in there. Check the bearings, if good grease them, if bad replace them.

[Cory]

Thanks guys for all the help. Do you think I should just replace that half of the case? I called someone yesterday they said that half is 100.00 plus shipping. Is that a good price?

[micmac]

That sounds like a decent price. Make sure you get the correct side as I don't believe that they are interchangeable. Something else to think about is reinforcing the T-20 mounting system. Many different ways to do it but here is what I did. Warning once you get a taste of modifying your machine you'll never stop

[JoeMeg]

Mike, that's a good idea and a nice clean looking job. I was not comfortable with the slots either. This is what I did.
