so after all day ride it sounded like fork in a garbage disposal! Rearend is locked so I pulled it apart an pinion gear is locked! (as far as I tore in) Think its the trans or the shaft?

 

Make sure your oil filter is in correctlly....I had an rancher in m shop that had oil filter in backwards an lock transmission down in 3rd gear.Do you have an 4wd? if so sometimes front brakes will lock down an stop transmission from turning! do alil more checking on these things an get back here with us. Good Luck

 

differential is good,final drive is locked. pretty sure its the transmission(damn)! its 4wd an has a diff unlock put on the front so it can be 2wd, hmf exhaust, 5' lift, snorkled, bored 30 over. oil is clean an shifted perfect? how would the oil filter be in backwards???? guess its time for a complete tear down(damn)! if the trans locked because of oil filter how do i fix that, tear it apart?

 

Oil filter is directional but can be installed backward by flipping it over an oil filter cover is hard to installed with oil filter in backwards but can be installed..The oil filter has an rubber seal on one side an that seal goes toward cover also it has an one way value on the other side an one way value goes toward engine and spring...Yes an complete tear down is needed to repair transmission just look at oil filter before you go any further so you will know what will be the next step.I oil filter is installed correct then get on here an we all can assist you further.

 

Can you take the rear drive shaft off under swingarm boot an see it engine turns with drive shaft off of output shaft? should be able to its spring loaded just slide yoke backwards an this should free the shaft from engine shaft.

 

If this frees up engine then check rear brakes or adjustment or you can try loosing rear brakes up first tho an try that to see if rearend will rotate

 

no rear brakes (as i go in mud!) took whole rear diff off, need to remove drive shaft next. Swing arm lock nut has a tack weld holdin it! SOB!!! slowing me down from tearing in further! oil filter was fine an oil is clean, no problems shifting either. Any an all advice is helpfuls I'm new to these machines
