PTO Shaft Replacement

[dactura]

FYI, thank you soundguy et. al. for the directions on how to replace my PTO shaft! Ridiculously easy!!

Soundguy is a guru so it took him 15 minutes to do the job... for a rookie such as I, it took 15 minutes to find the correct wrench in my tool box. Nonetheless, the replacement was quick and easy.

The photo is the old shaft and the newer shaft. New shaft was about $100.

I hope your front transmission seal was in good shape. If not, the 5 minutes you saved by not draining the oil out could result in filling the bell housing w/ oil.

Neither the front transmission seal or the rear wheel seals were meant to be immersed in oil.

So the tractors were never meant to run down or up hills?

HaHaHaHa :roll:

They weren't meant to have the seals
immersed in oil 24/7. That's a big
difference between operating it on unlevel
ground isn't it?

I don't think that what he did was 24/7. he will find out if the front seal is bad but if it was he probably already has oil leaking out the drip hole.

Yep, if it was bad it would be dripping out of the hole, so I don't see how completely immersing a bad seal in oil for any length of time is a good idea.

It keeps the rust down in the bell housing!!

Well, that's all good to know. I was wondering about running the PTO on a slope... reasoning that for a few minutes is okay, but for a few hours would not be. Then I was thinking maybe that's why there are three chambers for the fluid... but that's for you guys to decide.

I don't know where the front seal is, so maybe that will be a bonus for parking it for a while like that... I'll soon find out where the front seal is by the drip of the fluid.

I noticed an impressive amount of sludge when I pulled out the pto shaft! Thought I'd do the "drive around with diesel" in place of the hydraulic fluid - then drain and refill.

I live in the mountains and the 8n does go up a steep hill now and then. It is quite impressive as a skidder. 35 years ago, I drove a CAT 518 skidder. Pulling half a dozen logs at a time - the 8n will do okay with a single 12" 20' Douglas Fir.

There some cotter pins in drains hole on thes belly of tractor, they keep the hole open so if oil gets in there it will drain out. Front trans input seal is aft of the clutch. to replace you have to split the tractor.
When pulling with a N, pull from draw bar and be real careful, they will flip over real easy. I use my JD crawler for pulling doug fir logs. most of my property is pretty steep.

I cleaned out one of mine this winter, I removed top cover and used a spray nozzle with diesel and got it real clean. both the tans cover and hyd cover was removed to get to everything as much as possible. was happy with results. Replaced pump and piston and cylinder so good to go for years.

It would probably affect one in a million the odds are in your favor... Even it it did cause a issue you had the issue before and you already knew it...

I thought that cotter pin was what held the tractor together.

I guess this guy had some pretty bad luck.

Don't matter it was leaking before he ditched it... A good seal is not going to leak ditching it is not going to ruin the seal. For the record jack the rear tires off the ground no more than a foot problem solved...

Yes, I've read a lot about flipping those tractors. I hated the tires I have on the front when I first got the tractor because they look so cheesy.... but they are quite heavy with water. I have one of those CarryAll platforms from tractor supply (https://www.external_link.com/tsc/product/countyline-carry-all) and have the illusion the platform will help prevent any flipping. I put a hitch on the back that is attached to a solid walnut plank - 3" x 8". I drive slowly and watch the front tires. A crawler would be nice... but I'm not a mechanic. You may enjoy seeing the 1971 Lamborghini crawler owned by J Rickards https://www.yelp.com/biz_photos/j-r...AL9gUX7iQ&reviewid=gppVwxU9wLCVg7m7G-fZVA He uses it to plow the vineyard. He makes good wine also.

For some reason this picture looks obscene. Looks like the rear wheels were raised off the ground to keep the little tractor from getting away.

Hank has one of those front bumper/cow-catchers and it will accept IHC suitcase weights. I hang 4 sixty pounders on it sometimes. gm
