Hello there!

Have a Rubicon that when any load is given it would seem to slips and vibrates , I removed the motor and took off the covers to find the gears all in mint condition but the clutch shows signs of ware. The drum has signs of being over heated and the pads look worn, Is this a common problem or am I looking in the wrong place, perhaps this is over my head!

Signed Confused.



Thanks in advance Mike :huh:

Still looking for help!

I replaced the cluch and basket reassembled the motor and installed it,
The problem still there, have now taken the motor back out and inspected all gears and all is mint, When any tork is added it feels like a gear slipping, the motor revs up but the power is lost in something slipping, and vibrating as a gear would feel like when jumping? All the gears are mint and no sign of jumping?

Any ideas? Mike
:wacko:confuse

Welcome to the forums. The Rubicon has the Hondamatic tranny, which I know nothing about, except according to the service manual, it has to be replaced as a unit. That might be where your issue lies. The only other thing that I can tell you is that I've read that low oil pressure or a bad check valve can cause the problems you are describing, but I've not had any experience with the Hondamatic, myself.

What kind of oil are you running? If it's not the right stuff it's gonna slip like hell and burn up the clutches just like you've seen. The Rubicon trans uses the engine oil as hydraulic fluid and if the oil is synthetic or marketed as 'long life' or has 'friction modifiers' etc etc it may have undesireable consequences.

Honda recommends 10w40 or 5w30 (in cold climates) oil. The Honda GN4 oil might cost a little more than the Wal Mart bargain brand but it's designed for these bikes. For $20 and a half hour of your time it's a pretty cheap way to see if that fixes your transmission.

Oil formulated for cars engines is not the same as oil formulated for bike engines with wet clutches. Make sure you have the right stuff...it will take a while to get the wrong oil out if that was the problem.

I don't believe the oil is a problem i used regular 10w30, I have replaced the oil twice now dismantling it.
The clutch now replaced, and the exposed gears inspected, no fault found, yet it still skips when any extra trok is asked for,
When put into 5th the pattern of skipping changes frequency, the local mechanic suggested its in the rear diff, the output from the motor is solid
through the motor so i don't believe him or the front diff would be trash and the output would be turning, This ones getting frustrating and still looking for more suggestions.
I would seem its definitely in the case somewhere but where?

Thanks Mike

I have plenty of photos of it apart but dosent show much wrong?
I am swaying on it being the Hondamatic tranny but was told that part is bullet prof

slipping gears

low oil pressure or a bad check valve!

hummmm this is the next step perhaps the first one I should of tried:shocked:!

 

[micmut]

Found the problem

Took a bit of doing :lifting: but I replaced the Hondamatic trans and this solved it! Bike runs fantastic!
