Hestiation in 3rd Gear - Lesco Beldrive Walkbehind

I have a 3 year old Lesco 48" belt driven walk behind mower with a 15HP Kawasaki. I've noticed an intermittent problem when in third gear only. When cutting and the drive train is in third gear, it hestitates as if the brakes were put on for a moment. This occurs about every 30-40 seconds. The motor does not miss a beat. When in other gears other than third, this does not occur. Any help appreciated.........

third gear smoked, rebuild yourself about 30 or 40 bucks plus your time, having someone else do it about 180 bucks, or a new transmission 250 bucks.

Guys, thanks for the quick reply!! I was coming to the same conclusion but wanted to float it past the forum. So, if I try rebuilding third gear, is that just a sprocket that get's replaced? Being that I've never done this before, I was wondering if there is any "gotcha's" to be aware of?

I've never had one apart. Pinto sounds like he's had to deal with them before. Maybe he can fill you in more.

I have found rebuilding the peerless Tecumseh transmissions to be a worthless effort.
The aluminum cases are fragile, the bronzed bearings are pressed into the trans cases and are almost non replaceable and if one part of the tranny is crapped out the rest is following.
Try adjusting the shifting fork first as I have seen some improvement in the tranny staying in gear. If this doesn't work just find a replacement off of the internet for a $125.00 or so and install to be done with the problem.
Also belt drives are not really set up for running a sulkie so if you have one you MUST come to a complete stop before changing gears. This means clutching the mower to a stop, shifting the transmission into neutral and seeing the output shafts come to a complete stop, then shifting into whatever gear you select then resuming mowing.
The aluminum cased tranny's are extremely susceptible to accelerated wear when running a sulkie and shifting on the move, even with out a sulkie.

never tried to rebuild one before. Had one apart, and I knew why I never tried it. Best bet find a new one on the internet or somewhere.

Ah, they aren't hard to rebuild - they are just not worth the effort time wise.
The single biggest issue is proper spacing between the gears and the end play on the reverse shaft. Once these are removed for replacement specs get all out of whack so you have to have the shims and plasti-gauges for reassembly - like I said, not worth the effort.

Less than $200 for most of them.

Make sure you get the right spline.
