when I look at my manual I have listed 532141416 drive belt which seems to be a 83 3/4" belt? Ideas of "which" belt is correct for this mower so I can finish this off.....

Model number is LTH125 I went to the Husqvarna dealer, asked for a belt and they gave me the one that matched the parts list.....it runs and drives now but I had to take the idler pully off as the belt was way to tight to run with it on.....even with it not on there I cannot remove the belt...

now all I need is the proper driver belt for the machine, even though I bought the proper one from the Husqvarna dealer here it is much to tight it appears and jams against the belt keepers on the idler pully part.

Everyone likes updates right? RIGHT? well here is what happened I think. The drive belt being too tight on the machine and binding made excessive friction and would not allow the engine to rotate enough to start. Due to my not being aware of this fact it pushed the starter beyond its normal...

The plan is to leave the drive belt off until it runs well.

Main issue that I found with the "slow" turning of the engine was the belt I bought was too short. I believe the replacement for this tractor was a 82 2/3" belt when the original belt was a 84 1/3" belt or something in that range. Some people think size doesn't matter but it definitely does...

So I took the starter off and apart.....I found that 1x bush was disconnected, and another wire came apart from the brush when I touched it. these were on the "neg" end of the starter. Tried bench testing both before and after I thought I fixed it and nothing, no spinny spin. I'm hoping that...

I should also mention that i think the starter is dead, it still turns over the starter on the key, however the stsrter does not engage the flywheel to turn the engine over. This has been quite the project, never again will i attempt this type of mower repair....lol

So just a random update on this. Everything is all back together and still the problem persisted.... So I started looking deeper. I found one problem was the main drive belt is way too tight, and it binds on 2 of the "keepers" and just doesn't allow the machine to turn over. I loosened the...

Can anyone confirm if on 286707-0441-01 12.5hp Briggs engine has a compression relief built into the Crank/valves? Ie does the crank keep one of the valves open slightly to bleed off the compression to allow the engine to rotate to start? when I rotate the engine clockwise by hand, there is a...

Noted, I'll keep that in my records for the next(if ever) time I do it. I have to fabricate a spring compressor so I don't buy yet another tool for a 1x build. I thought I had it done but the one I built didn't' work on the exhaust valve spring. with that I'll pull it apart again and reset...

I used a flex hone...I think. the arms were not rigid, there was nothing in the cylinder that looked bad, nothing that was pitted, gouges, nothing to catch a finger nail on or anything. it seems to seal well with the new rings installed, but also seems to build compression to the point of...

This is my first time adjusting the valves. I removed the valve springs, removed the valves, cleaned them with wire wheel, cleaned up the seats with emery cloth. Once everything looked clean... I lapped them in with lapping compound and a lapping tool but doing the quick back and forth in my...

Thanks for the reply! it's a Briggs L-Head, with the side Valve cover off and the top of the head removed to expose the Piston and valves I rotate the engine and the valves go in and out as normal as the piston cycles though it's stroke. The rocker arms were snug against the intake valve stem...

minor update on this. I just pulled it out again and started working on this "winter" project. both valve clearance were 0.00 I couldn't fit anything between the tappet and valve with the engine at TDC. I've curious now though about how this might effect my slow turning over problem? it...

There was nothing that hung a nail on, just some glazing from the engine sitting with old oil/water in it. the cylinder wall was clean when I finished and the new rings seemed to seal well, when I installed them on the piston and then into the cylinder id didn't appear to have any ovaling to my...

thanks all, I'm feeling more and more like I can get this thing running again and well. I've had luck with another tractor rebuild I did and hoping this one goes well too.

my god I love those guys....their videos make me laugh!

excellent and thank you. Yes when I pulled the camshaft out the lifters fell out....actually more then once. they appeared to be the same length and size so I didn't really think much of it and just stuck them back in the way they came out. Is it possible that something else was stuck up the...

it's an L head or flat head, not a OHV engine. I had the head off the cylinder but didn't remove the cylinder from the block only removed the piston from the cylinder and then honed it. I used medium stones on my power drill. Sorry I don't know what the different terminology are for...

I'm stumped....but then this is literally the first engine I've gone into this much depth on. Background: Briggs 286707-0441-01 12.5 HP I/C Quiet engine that slept in a flood for a year. I grabbed it, drained the oil and fluids etc....replaced the carb with a chineasium one and it fired up and...

Hi. nothing to really see here....just a guy frustrated with working on old Lawn Mowers.... From Canada
