Default L175 trans rebuild

Group,

Been using my L175 for years with a grinding pilot and or throwout bearing, Little reverse gear left and fear that it would all someday come to a screeching halt. It has not but I have amassed the parts I feel I need to rebuild the tranny including Main and reverse shafts, reverse gear, bearings, seals and a complete clutch setup.

Was thinking about sending the hard parts out to be Cryo-treated, but have been more concerened with making time and patience to split this unit both front and rear, lay it on a table and disect and rebuild it after a good cleaning.

Anyone have any pointers in doing so, any shortcuts or time savers in either the breakdown or rebuild, tooling or upgrading while in there...

Thanks,

Joe-NJ

Replace all the transmission gears that are ground up, chipped or "sharp". Use new thrust washers and take your time. You don't want to find that you missed putting in a PTO gear when you're bolting down the stick shift! (Ummmm, ya, been there)

Joe,

Like Vic said replace all questionable parts; it is easier to do things once than several times.

I have neve been inside a tractors transnission, but I have rebuilt manual transmissions for pickup trucks, and a lot of gearboxes for gun mounts while in the Navy.

I wil be watching this thread for info; my L175 likes to pop out of reverse.

Hey Robert, if that's what's happening, the square edge of that reverse gear is worn down. Simple fix for a Navyman!

Thanks Vic,

I will probably wait for spring to work on it as my shop is not heated;although waiting has drawbacks since this is my primary lawn mower. The Woods L59 cuts the best and most even of anything I have ever used.

Robert,

Whaddayathink? Should we dive into these while the time is right? Luckilly I work in my familys automotive shop and have a few young apprentices that I may trick into helping me. Got my manuals and parts, just not the experience. Splitting the unit is probably the most intimidating but not being under the gun, may make it actually interesting. Just getting tired of not being able to look behind me while holding it in reverse .

Joe,

If you have the manuals, parts, and time to do it; now would be the perfect time to work on it. Just be careful when splitting the tractor, and maybe make some splitting stands to support it while you are working on it.


Good Luck,


Robert

Hi Guys. When I split my B7200 I also put blocks on the axle stops. Otherwise the front end will tilt sideways when you split it. Keep us posted. pics lots of pics. Dusty

So the tranny worked out well. Replaced most if the gears, bearings and seals. Its just nuts and bolts. Sourced gears everwhere I could. Part numbers are vital. Used tractor oil and it was noisey. Swapped back to gear oil and lucas and smooth sailing. The fork is more intimidating than difficult. Had one shaft down deep that was seized and had my machinest massage it smooth again so it glides over the pall with balls in it. Was not cost effective but its right and will last for another 50 years. Painted her up, upgraded steering gear and put on a rops. Up next, lights.
