Argo conquest trans 'freshen up'

[mitchamus]

hi there,

just wondering if anyone can point me towards a good resource on refreshing an Argo conquest trans?

I was thinking of just replacing all the bearings in it....

The one I have doesn't sound too good, and doesn't shift unless the clutch assembly is stationary

...also sounds like bolts in a blender...

I have just managed to download the service manual.... looks fairly straight forward...

finding the time is going to be the hard part...

Follow the manual. Its very straight forward. Check you transmission model number before you start. Order a gasket, oil seals, and blanking plates before you start. The tranny was my first argo project. The manual is very clear on removal, and splitting the tranny. I didn't disassemble the differential unit, as my problem was on the reverse idler shaft. Take Pictures as you take it apart, and ay attention to the orientation of the gears. I wouldn't try it without a service manual in hand.

thanks for the advice.

I also must make a new friend with a bearing press

I hope it's just the bearings that need replacing.

the price on the gears is a bit shocking....

Where did you get your transmission parts from. I thinking of doing the same thing down the road before something do,s go wrong.

No parts as yet... Still doing my homework

I did mine with only simple tools, and the parts manual drawing. Make sure you have a freezer available, and a bearing heater (hot plate with a piece of sheet metal on it). You will need to take the differential apart to get all the bearings changed. None of it is hard to do. Just be patient and take your time. Don't force anything because stuff is expensive if you break it.

I ordered gaskets and gears from our local argo dealer. I have one of the early transmissions (CHK Series) and was scared parts wouldn't be available. I didn't really like the price but what I needed was available, so ya gotta pay to play. Bearings, Oil Seals, and Blanking plates I ordered from a local industrial bearing supply. Gears are pricey, $100 for the reverse idler gear here, I didn't price out the rest.

[mitchamus]

Yes - I'm hoping that I don;t need any new gears!!!

first thing I need to do is service the driven clutch and then give it another test run to see what the real transmission noises are...

reverse sounds horrid!! like someone is strangling a feral cat!!!

Reverse gear idler 34-16

Apparently the reverse idler gear is upgrade from oilite brass bushings to bearings and that cost 90 usd to change.

Any experience is IT really needed to change to the new 34-16a reverse idler gear with bearing ?

The reverse gear (if it is full length cut) is reversible if the bushing is good.

Now if you are riding local or in a group the extent you go can differ.

What I seen in your pics, kinda, looks as if the input shaft and the high low gear are pitted probably from all the water in the oil, they both have wear and are sharpening which will eventually cause jumping out of gear on deceleration, generally the bolt noise you may be describing is in the planetary/spider gears which also sharpen and often one end breaks yet stays in place so you will want to open the cage (which you did not show). While the cage is open do the bushings and be sure to Loctite the 3 bolts (been there done that, again), if they are sharp replace them. The main gears generally stay decent if the metal has not gotten chewed by them, if so your bill just went way up.

Often times some excessive noise is actually coming from the driven clutch bushing wear throwing the movable face out of round.


Lastly, if the trans is a G it will wine like a cut cat, that's expected but grumbles and the like are not. One way to tell if the shaft and hi/lo gear is bad is if the wine changes tone significantly on deceleration.
