'48 JD G main case gasket leak-Clooney, JohnT

Hi guys. I have a 48 JD G with narrow front. The main case gasket is leaking where it bolts together above the drawbar. I tried tightening bolts, but they were already tight. It is pretty much the only leak on the tractor, and gets pretty damp under there pretty fast after washing. I've been all through the engine, but never back there in that area.
I wanted to know what all fell out or came loose when splitting the tractor here and how to hold on to each half while doing this gasket replacement. I have thought of making some stands on rollers to bolt to frame and rear axle housings...
Wondering if anyone has done this and how they hold on to the tractor halfs and if anything will fall out when doing this.
Also, should I use just a gasket, just gasket maker, or both??
Just seeing if I can handle this or not. Maybe I am better off to let it be, there's nothing saying it won't leak after I replace it!!!!
Any help appreciated.

Nathan

Nathan, first, of course, drain all that nasty oil and we try to let it drain a long time first. Mine that we had to split and when I helped others were done at Henrys shop cuz he has a power chain hoist on a roller track in the shop floors center. The only thing I remember (its been a while though) we had to be concerned with was the PTO shaft, it has a male splined (inside tractor) end that slips into a female coupler and Im pretty sure she pulls straight out no problem. WE got oak blocks under the front and had it blocked and chocked up secure as a drum. We used the power hoist with chain around the rear and had another like an adjustable height roller frame (I'm not sure if thats what he uses for a transmission jack, I forget??) and loosened her up then put some rear presure on the track hoist and she cracked and more nasty oil ran out and she came apart. The pump and PTO all drive off that splined shaft and I dont rememebr having to unhook anythign else for the split. Theres external steel hydraulic lines on later tracors, but I dont think on that G and all I have here at home now is a 620 and 38 B??

WE use new gaskets and I thoroughly clean and polish and smooth and have dry all mating surfaces. I use maybe only a light spray on type gasket sealer to stick the gasket in place (Sorry, I forget if it has any dowell locators???) and DO NOT use any silicone type form a gaskes in such a place with a new paper gasket.

Its not my favotite job and I hate that nasty oil lol but with a chain roller hoist and air tools and plenty of oak blocks and that jack and the buddies all there and a good country music radio station on how bad can it be??

Good luck n God Bless, sorry its been a while since we split one so my old brain cells dont remember anymore. Im sure others here have split some more often and not as long ago who can help.

Use Caution and double chockign and safety n security. God Bless ya Nathan John T

PS Im glad to help where I can on these mechanical type questions, but Im more experienced in electrical matters remember and an electrical not any mechanical engineer fer darn sure.

Nathan, you shouldn't have any problem splitting that tractor at that area.. Just pull the PTO shaft first so you don't bend it..

~As far a splitting stands go..You have a few different options.. I usually just bolt pieces of angle iron to the sides of the front frame at the rear to stabilize it, then place a few blocks under the main housing , then roll the rear part away with the wheels still on it using a floor jack under the drawbar [you might have to add a little weight to the drawbar to keep it from tipping]� The other way I have done it is to pull both rear wheels & just use a floor jack under the center of the axle housing [kind of balance it on the jack]..

~One thing you might consider doing is to go a little farther & install new rear axle seals in the rear housing as you will be close to that anyhow..

~On the rear gasket, I definitely recommend a gasket. That gasket eliminator is sure to cause you a future problem as those cast pieces expand & contract.. I do use a gasket reinforcement on the gasket though [like Loc-Tite 518]..

~One thing you might consider�Years ago I had an �A� leaking like yours is.. I just pulled the rear housing apart about an inch or so using blocks to hold the front up & long bolts to slide the rear back on & stabilize it.. That allowed enough room to scrape the old gasket off & clean the surfaces.. Then I split the new gasket on the top using a puzzle like cut.. Then I installed that gasket between the two halves & pulled the long bolts out as I added new ones through the lower gasket holes.. When I was done I used sealer at the top gasket cut & bolted it back together.. It was kind of a pain but did work good & never leaked

~I split an unstyled �A� a year or so ago using the angle iron legs I spoke of above. I�m not sure but I might have a picture in my archives showing that stand set-up.. Send me your E-Mail address & if I find a picture of those angle irons on that �A� I will send it to you..
