Hi Daryl, where is the rest of the teeth? Do you need a dentist?

I would replace it or if its a parade tractor just switch it to the other side of the tractor if you have the the other side apart. Might have to replace the pinion gear too.

Hello Daryl,

The good news is that if those bad teeth are on the pressure side for reverse, then you can get away with keeping it, if it's for a show pony.

If it's not, and you can't get a new one (at a good price) then I would spend some time cleaning the teeth and then carefully fill the pitted areas with phosphor bronze and then dress back to the correct profile in a shaper or similar. Oh, and I would quench the teeth as soon as the bronzing is done on each tooth. That should maintain some hardness. They are usually only induction hardened on large gears. Plus the bronze will add some great bearing properties.

At least it's repairable. 😖mile:


Cheers,

Phill.

Hola Daryl,

You need to put out some rat poison, that's a rat eaten gear. What would I do? reverse the gear and drive on, it will last for years. Some tractors you can reverse the gear on the same side, others you have to swap sides.

How is PON?

Hey Neil, I'm surprised you and D23J have time to be on the Forum, the Barmaid at the Tintaldra Pub must be shaking in her uggboots when you and Andrew darken her doorstep each night for a pre-dinner cocktail, by the time Mrs Wombat drags your sad and sorry backsides home for dinner I bet there isn't a dry eye in the Pub with all the great jokes that get told, I'd love to be a fly on the Pub wall this week, beer sales will be up 200% easy!!😖mile:

Sorry to go sideways on this thread rax200, you know Neil better than I do, but we both know his sense of humor is second to none so I thought I better throw a biscuit of hay to the Colt from Old Regret and keep him poking along, maybe he will find time to write a few words for the next ACMOC magazine about what he and D23J are getting up to this week.

I reckon the boys are on the right path about turning those bull gears around too, sounds like you are doing a full recondition of your D4, keep up the good work.
All the best

Hi all i have decide to put it back in and just drive in reverse that will fix all the problems, and the gear box had the same rat problem so i'll put them in reverse that way when i go in reverse i'll go forward. :bowl:

ROME/KG Yep the pinion and most of gears in the box was buggered too, so i replaced them all with the ones from the spare machine and i be will this weekend start pulling the bull gears from the donor too as i now they are like new

Andrew i put some rat sack around to keep'em out

Wombat Pon's good she will be coming to the meeting on Friday

Hi Phill thanks for your reply i would never thought of that a very good solution i will keep the gears in case some one requires any

PS: this is the good side i post some more pics when i do the other side.

This reminds me of a story...when I was at the John Deere shop, the salesman who was always doing deals on his own came up with a nice D4 Cat with a bad bearing in the right side final drive. He parked it on the pad outside the shop & proceeded to tear into the final, where he found that the pinion bearing had wadded up & caused the main case to crack, up from the bearing bore...so, what to do? The Cat sat outside the shop for almost a year, until he found a welder that wanted to mess with it. He came & stitched the case back together, & did a nice job...Salesman had pulled the whole rear end apart, steering clutches, crown gear, etc...he got her all back together, fired it up, put it in 1st, & it went backwards! Put it in reverse, & it went forward! The look on his face was priceless, he tried several different gears with the same result, shut it off & cussed for about 5 minutes. He had put the crown gear back on the wrong side of the pinion...had one forward & 5 reverse. He said "I didn't think it would go in the wrong way." I said I didn't know either, but I guess we do now. I didn't dare laugh, he was too pissed, but he got more of a sense of humor about it after he cooled off. He pulled it all back down, flipped the ring gear over, & it worked fine. Sold it to a farmer & he got a lot of work out of it...
