Case 644 loader repairs

[Jancoe]

My 6018lbh had the cover plate on the top of axle. So bottom of frame. On my 6018l the cover plate was on top of my frame. When I serviced both, cover plate went on top frame. I installed gasket maker between frame and axle. Then gasket maker between cover plate and frame. No cork gasket. Then I used pipe sealant on the bolts that threaded into the axle case to prevent water intrusion. I do believe Bill at Barneveld said they don't sell many and his brother used gasket maker when they service ones in shop.

Hm, I suppose I need to clean and seal the space between frame and axle too. What's the gasket maker of choice for you guys? I have used Permatex "The right stuff" on the car a few times.

Is there a reason you didn't use a little gasket maker under the hex cap of the bolts, rather than using pipe sealant?

My go to for casting surface like that is Permatex Ultra Grey.

Eugen, the service manual for the rear axle calls out for pipe sealant to be used on the top bolts. Like David, I also like ultra Grey sealant also.

Thank you @Jancoe and @DavidBarkey!


At this point this isn't the most enjoyable type of work to do on the tractor, but needs to be done. Frame separated from the axle. No evidence of rust in between, none at all. Same holds for the gear box interior. This is good news. With fresh oil and sealed well it should last many years.

@Eugen Only one way to know for sure , and now you know it is right .

There was a Napa near me, about half the distance from me to the Canadian Tire store, which is where I'd normally get the Permatex Ultra Grey from. Besides the fact that Napa is closer, it's a smaller store too, and I like supporting the little guy around here as much as I can. Went there yesterday to the the Ultra Grey, turns out they moved location to a spiffier building, up the street. Fine, I go to the new location, obviously they're still moving stuff, so nothing got prices on. Grabbed the Ultra Grey from the wall display, and also asked about the o-ring used on the inlet tube where it inserts into the hydraulic pump. He didn't make much of an effort to find me an o-ring of the same size, ok, fine, they're busy with the move and such. Ring me the Ultra Grey then, please, I say. He does, and I'm shocked the total is almost $20. So, I say, how come on the Napa website it's 12.99, it's 12.99 at Canadian Tire, and 12.99 on Amazon (free shipping). He says "I dunno". Paid and went home, resolved that for the $5 bucks they greedily gouged me on I will never shop there again. My first ramble for today.

I went to home hardware today to get light bulbs. Saw a buddie of mine there, who works at the store. We were shooting the you know what and I noticed a price on a spray can of red rust check. $15.99. Jumpins.
Not to long ago they were $9.99? It’s expensive to stock your home hobby shop with stuff needed to do your hobby repairs.

There now, a quick ramble on hobby shops.

It has held up for the past 7 years on the machine in the video. This is a paste and is the an replication of product that is used in CNC grinding equipment that was OEM at $75.00 per tube. Permatex is 10X cheaper and is what I use on Case Ingersoll differential covers.

Thank you @Spike188 , if I had know about this before getting the Ultra Grey I'd have ordered it from Amazon.

I looked at the receipt from Napa and apparently the Ultra Grey from them is non-returnable. Oh well, live and learn.
