intermittent skip on lesco wb

[coldgin]

i have a 36 in lesco wb with a intermittent skip in 1st and 3rd....i changed the drive belt and the idler pulley was worn but still skipped after replacing....i changed the shift keys and it worked fine for about 3 months....what gives?i inspected all the gears and they look fine...this mower mows all day long in 2nd but shift to 1st or 3rd the skip starts...any input is appreciated...

The flat thrust washers that are between the gears are probably worn out..
The washers are what lock the keys into the gears...
Also look at the gears to see if there is any wear in the area that the keys ride in.

thanks for the info piston slapper....i will order me some washers...i already changed the gears also failed to mention that in the thread...i will let you know how they work out...

The washers are directional...make sure they go in the right direction.

piston slapper what do i need to look for when installing the washers?would you put new keys in with it or use the ones i have....they probably dont have 25 hours on them...

The washers have a hump on 1 side....look at them when you disassemble the shaft..
I realize you need to run the mower till you get the parts...
Ideally ....I would disassemble and inspect before I ordered the parts.

i clicked on the icon for jacks small engines and they have the washers for 2.75 per washer...probably will change out all the washers on the forward gears but i am going to order them after i tear it down and check them out...i will let you know what i find...

ok the tranny is apart....i inspected the washers and now of them seem bent,any abnormal wear,they all look the same...i did have one washer oriented the wrong way...and i am assuming the taper on the washer faces away from the gear so when the shift keys have engaged the washer it will keep tension on it...also i found a schematic online so i am going to compare what i have done to what is in the schematic...anything else i need to look for?
