I have worked on these gear boxes from Different models and have found that the ones with different shafts the gears are slightly different. the main thing is the I.D. bore. The one thing I have done is to swap the complete gear box from one tractor to another. the bolt pattern to mount to the frame has been the same and just use the pulleys and the pto clutch from this unit.
Simplicity 7110 BGB gears
I bought a simplicity 7110 that owned new from the guy I bought it from.The tractor runs very nice,however he did say it was making a lot of noise comming from the gear shift lever area.As soon as I heard it run I shut it off,because of all the noise it was making I knew there was a problem with the BGB.I struck a deal with him and it was mine.After getting it home the first thing I did was remove the MMM and took the shaft off the motor.I knew there was a big problem with the BGB as the front brg and seal were gone and the gears wouldn't mesh.Anyway I picked up a older landlord just last week that has seen better days,however the BGB seems to be good.Now my question to anyone who knows are the bevel gears the same in all of them.I know that the shafts are different that come out each side but what I'am hoping is that the internal gears and front shaft are the same.Anyone have any ideas.Thanks.Larry

Thanks for the advice.I haven't had time to pull either yet but hopefully will get a chance in a couple weeks time.LarryI have worked on these gear boxes from Different models and have found that the ones with different shafts the gears are slightly different. the main thing is the I.D. bore. The one thing I have done is to swap the complete gear box from one tractor to another. the bolt pattern to mount to the frame has been the same and just use the pulleys and the pto clutch from this unit.
When you get the bad one apart check the teeth on the gears for wear or breakage. If they aren't bad you may be able to just replace the bearings and seals. Let us know what you find.:fing32:
3400 series up through the last of the sovereigns produced should share the same input shaft. I'm not sure what the 3300's had but prior to that (basically all of your 60's tractors) had an input shaft with a smaller diameter and cannot be used in your housing. The output shafts are different on many models also.
Thanks for all the replies.I guess the only way I'am going to find out is for me to dig into them and see. I did take a quick look out at the parts one,and it can probably be brought back to life if I really want to. Its a Landlord ser# 001818 couldn't find any model # by the ser#.The tag is on the steering wheel/tower,dash on the lower left corner right about the shift lever cover.This tractor has the front grill that bolts onto the front and then the hood fits on top.Its a standard tractor with the variable speed slector also.There's a hydralic pump under the gas tank and the lift or control valve lever comes out that side.The motor has been changed I know this because I had sold the motor to the guy who had put it into the tractor.It has the starter generator on it.In fact I also have the original motor that he gave to me a couple years ago when it put a hole in the block.Anyway I should have taken some pics of the tractor but its kinda not put together at this time however its all there. I took a good look at the BGB and the shaft that goes thru the box is different then the one thats On the 7110.Guess the only way I'll know if the bevel gears will work is when I tear into them.Hope there the same.Larry
Sounds like the Landlord is a foot dragging tractor. The input shaft is too small and I believe the input gear is different. Most of the internals do not interchange between the foot draggers and the running board tractors.
