Should I?

I dont know if most of you have been following my situation. As of now, I have the hydraulic res on my 300u cleaned out, and an external filter installed. I have the cover back on and torqued up. Now I'm wondering if i should have taken off the tranny cover to inspect the rear end. I'm thinking that 2 of the res cover bolts go through the cover, and the tranny cover and thread into the tranny, which would be fine, as I dont think it would effect the res cover gasket when removing the assembly. Now there is maybe 4 other bolts that might thread into the tranny, instead of the tranny cover and that might be a problem messing with those after the gasket has been installed.

It would be nice to catch any bearings going bad or gears going out. there is no abnormal noise, but just knowing everything is in good shape would help me eliminate one of the 4 areas of concern. These areas are the following...
1. rear end and gears/shift fork - I have no idea what shape they are in
2. engine condition - The engine oil pressure is around 55psi and tapers to about 50-55 when warm, no real noticeable difference when its warm. engine runs good and only has a slight noise to it, more of a tapping sound, but only when reved up loud, and it is still barely noticeable then, I just pick up on these things. The engine was ran without a good header system for years unfortunately, and has been repaired since i got it. One day I'll try to get a recording and get your guys' input, but for the most part I think the engine is in good shape for its age.
3. Clutch - I have had the inspection cover off when i was working on my starter problems. The clutch disc is worn fairly good, but I'm not addressing it until need be, no slipping at all.
4. Hydraulic pump - I was getting the notorious hydraulic pump whine. I'm hoping my expendition into the hydraulic system addresses this, or helps to alleviate it. either way, the pump is more then capable of lifting over 1200lbs with my loader, so I'm happy, and theres been no noticeable decrease in power. I'd like to get a pressure test on her sometime just out of curiousity. The whining bothers me the most, but as I have read, it is not necessarily symptomatic of impending doom.

I'd like to get one more of these possible problems/main cost areas assertained.

Any knowledge on whether 2 or 6 of these res cover bolts thread into the tranny case in addition to the standard tranny cover bolts would be greatly appreciated.
Thanks guys
I checked out caseih and theres no exploded with the tranny cover that shows what bolts thread where.

JayWalt; You can remove those broken bolts if you can get to them with a welder, a mig works best. j ust place nut "not me" over the broken bolt. Even if it is broken down into the threads,with wire welder, you can weld up to the nut. Most times it turns right out. I sheared the flywheel bolts of of Cummins engine.Our company welder used this method to take brokem bolts out of the crank,run a tap thru. the threads,new bolts,two days, she was up and running. Welder said ,the reason bolts broke,was they had crystalized. He used 20 nuts 6 bolts in 1/4 lenghs. Did learn one thing,grade 8 bolts didn't last but 3 mos. Ordered bolts from cummins second time.1 1/2 yrs. later shes still running fine Steve

Yup. My dad is the mantainence forman for a local quarry, he actually works for a dif company, but is contracted out. There is a time and a place for grade 8 bolts. They rebuilt one of their towers with all grade 8 bolts. Well needless to say, they were replacing bolts left and right. Dad suggested using grade 5 bolts, they laughed. So dad was the one responsible for changing them, so he put grade 5 bolts in, after about 2 years he had them all changed and no more breaking bolts. Grade 8 bolts are too brittle for a stone crusher, the vibration just snaps them.

It depends on what your objective is and how much time you have. When I buy a tractor, I check compression on the engine, unless it is more than a "reasonable" difference from new specs, and if the readings differ less than 10% from each other, I leave it alone. But, I ALWAYS pull the trans cover, look inside and clean all the old oil, crud, etc out of it. You will likely find that the gears are worn about 30%. With no missing teeth or ready to fail bearings, if you heard no noises, that is probably OK, unless you plan to really use the tractor. Word of warning. If the top cover on your 300U is like the one on my 460U, you many have trouble getting the thing off. The 460U cover is 2-3"? inches thick, meaning that the bolts are rusted in that depth. I broke a couple of mine off and then hung the rear of the tractor by the boltless rear cover for a couple of days before I was able to work it loose -- have fun!

Jay, from your own description, it is fine in the finals/trans. Opening it will introduce more issues than leaving it alone. Probale cause is needed for exploratory surgery. Change the fluid and go on with life. By the way, I feel (even if it was my idea) that the added filter is not cobbled, but an improvement no different than adding lights. JimN

Thanks Jim. I had thought of the filter way back when before i even considered taking the res cover off. Your suggestion helped to affirm my course of action. It was TOUGH finding a location for it to mount, but I think I got it squared away. The best thing about the filter setup is it has bleeders on it, so i can open them, and shoot a litile air, (probly set the regulator at like 5-15psi) into the resevoir to get the suction tube full of oil (I already filled the filter with oil) to help get the system primed as fast as possible. Today I also addressed my lift arm hydraulic lines, welded on some mounting tabs to a pipe that goes behind the battery so its not flopping all around. I also fixed my seat, the groove most uses was broken over to another goove which slides the seat back and forth. IT could moved about 2 inch eithr way and made for a weird ride. I took it apaprt, welded it up, reground the groves and relubed it. Theres 2 big ball bearings in there on each rail, pretty cool setup, now adays, it would just ride on the rails.
I've decided not to mess with the tranny cover. I will check the plugs tomorrow and see how things look. It would be nice to get it off, but its simply too much work.
I have to say I really appreciate your input, as well as the rest of the forum members. Without you guys I would be lost. I'm failry mechanically inclined, but lack the confidence when it comes to new things, to just jump in there and "mess it up" =)
Tomorrow I hope to get her finished up so I can run her a bit and check it out. This summer I'll give her a good wipe down. In my opinion its the best way to clean it is just a crapload of dry shop rags. It gets the majority of the grime off and makes it look a little better. Power washing it would do so much wrong to it. First, it would get water in everything I'm sure. Second, it removes all of the oil and the rusty areas just continue to rust faster. My tractor is far from pretty, but I like it. My next project is the rear axles. Seem the right side grease zerk doesnt want to take any grease. I'll do some reseach first...

Jay, ol' pard, why look for trouble? The way your luck has been going lately with your tractor, you're bound to find something that looks less than ideal. If the gears are working fine and are not making any strange noises - then I'd suggest changing the fluid, pray over it, and leave it alone. mike

well i thought about it, and i'd have to remove the darn hydraulic cylinder mount, the rear rockshaft mount, which already i have broke one boltoff in, hah. not right now i guess, come summer maybe i will mess with it get that broken bolt out and helicoil it, it just would be nice to know. ill check the fluid level and condition to give me an idea.
boy if i had the room, funds and equiment, i would love to restore this tractor properly instead of cobbing together stuff like thefilter tomake it work. haha. oh well, least its not rusting in a field.
Least it doesnt have a TA, which would be nice if it was a NEW one, but given the option of no TA, or a 50 year old one in unknown condition, ill just do without =)
Yeah, it'd be nice to go slower sometimes, but not too often for what i do.

JayWalt,

I feel your pain as I have a 350ute that I have removed the same cover.
As far as looking into the rearend, why couldn't you remove 1 bolt at a time & hold on the outside to see if in fact it is threaded into the rearend or just the cover.
