Max IV, T20 or clutch issue?

[msafi65]

4" of total travel front to rear is a bit tight. MaxIV should be 7". If the stick travel is correct the bands are adjusted properly. The symptoms are classic for the clutch. Spinning on the input shaft, they hold a bit then slip again. Try prying out on the driven clutch and see if it will move on the shaft. Normal is about .020" to 1/16" of end play. All the workshop manuals as such are available if not on this site I have electronic copies. The manuals are pretty basic but helpfull. The t20 rebuild section here is great info. Good luck

Hard to see but that spring looks sprung, get a better/closer pic of the clutch.

Since I have no idea what the clutch is supposed to look like I'll have to take the word of an expert. Now ask me about helicopters and I can tell you just about anything

Here are some pics I took tonight, I had to illuminate the clutch to get a decent pic. Whadya think?

I had to do some tinkering on the carb since apparently my fuel tank cleaning didn't quite get all the garbage out of the tank. Anyway, I had it running and tried to prove my point about the steering fading after a few minutes. Needless to say it did fade but I let it sit idle for a minute or so and tried it again and it worked, a little jerky it seemed to me but it steered regardless. So I got about 20 minutes of total ride time around my place on grass and clay, other than the apparent brief slippage it seemed to run fine.

Maybe I was seeing things, anyone else have an opinion on the spring?

I think I would swap it out for a red one. It looks a little worn, and the 18 is a pretty small engine for a IV. Other than that, it looks ok. I'm still going with adjusting the bands.

Is there a way to adjust the bands without the special tool?

In my eagerness to get the show on the road after 7 months I guess it was just wishful thinking. Ugh, lifting heavy stuff~~~~~
