oleman Posted May 20 Posted May 20 Gland Wrench is just an adjustable pin type spanner wrench, mostly same as the wrench that rotates the hold down nut on a Red Chinese angle grinder. I have made several over many years, none have ever come from Snap-on. BUT I can see how a profession hydraulic Tech would want a perfect fit every time. Quote

Previous options will tax the abilities of a six armed ape to hold everything. I have one and the only reason it doesn't go to Norfolk and get melted down is my reluctance to spend money on a better option. Quote
mmi Posted May 20 Author Posted May 20 If it was a 6K hr 590 never kept in ,never opened,abused ,locktite,yes I would want $500 -NLA ,4 pin+ 4'pipe wrench+ 4' pipe+ heat ,10 hands ,4t vise mtd to floor. original 530 with screws holding gland on not so much... 2 hours ago, Gearclash said: is my reluctance to spend money on a better option. Which are........ no afraid of real tools 1x As their ALL china, not seeing the $350 difference. And only the most well paid kids, at steeler are going to have Co owned snap OFF!! 2 hours ago, Gearclash said: Last one is maybe OK Most steelers use/sell that one in $$$ fancy box. Waiting for bids on seal kits.....will try to borrow,until $ OTC or 3-4 pin..... Quote
New Englander Posted May 21 Posted May 21 I made one for my bucket truck's lower boom cylinder. Trunion pins would not pull so I disassembled it in place. I made it out of half inch plate with grade 9 socket head screws for pins. It was a bear to get apart. I rested the boom against a tree so I could remove the cylinder piston, used a heavy ratchet strap to keep the spanner pins firmly engaged while using another strap on a long bar inserted in the pipe welded on the top of the spanner to keep a constant counter clockwise heavy tension on it. With that setup it still took a lot of 10lb sledge work to get the nut loose. Here's the top view with the pipe for a bar that I thought would give me enough leverage to simply unscrew the gland nut - wishful thinking. Pin side: Hammer persuasion marks: Quote

These should be 3' pipe or less While most after'80 require BIG tools and heat + loosen on machine,otherwise (all ) threads were backing out with new pressure and # loads. NE 's tool is nice ,but "cut " steel is $2x a factory tool here Where are (all) ordering seal (kits)? These are STD but not off the shelf any more. https://www.mycnhstore.com/us/en/casece/na/light-equipment/loader-backhoes/naes49loa211backhoe/backhoe-and-loader-for-530ck-tractors/complete-machine/lift-cylinder/cn/CEE50978-8FBF-E111-9FCE-005056875BD6/9DCD6496-EFBE-E111-9FCE-005056875BD6?modelSerialSearch=true Quote
acem Posted May 23 Posted May 23 If my spanners don't work I get out the 48" Ridged. Seems to work good breaking them loose. If y'all'd quit soaking everything in salt you would solve alot of problems. Quote
acem Posted May 23 Posted May 23 I get my supplies for resealing cylinders from different sources. If I take it apart, everything looks ok and it's not hard to get on and off. I just put new O rings on. Get the O rings in bulk. Use N Buna Druo 90 O rings. Wipers can usually be replaced with a seal from a bearing store. Rare more than $5. If I need to get all the parts I disassemble the cylinder into the major groups (barrel, ram, piston, end). I take these to my local hydraulic shop and match them up. Typically 20- to $100 (for a big one). Very rarely go to the dealer. Quote
acem Posted May 23 Posted May 23 When I take a cylinder in to my shop that has that type of piston they will offer to build a replacement piston that uses standard O rings and Backup washers. They say they last much longer and the rebuild parts are cheaper. Expensive the first time but cheaper from then on. They have their own lathe & mill for making replacement parts. Quote

They say they last much longer and the rebuild parts are cheaper. Expensive the first time but cheaper from then on. They have their own lathe & mill for making replacement parts. We (neighbor )did that on one t340 30 yrs ago as no "shops" then. (And have re-contacted the blanks supplier,(son) ....buy new.) Prior, local contractor had 10000's cyls on gradall/dozer etc, full time builder and 1000' of parts to hunt. We did have a (3hr drive ) shop reopen, at "cheap" $125/hr ,decent work on broken but usually $ 90% of new. 3-9 week wait. As it is time for 14 cyl on just this one $2500/10 + $1200/4.....Add $2 in" for 50' of hoses too.........like everything today keep the paint and drive "new" machine under for less $ "leathers" in kit form are +- $12/more vs "gland " $12-32 kit on both ends.But last 2-3x. Most of these are 1.5-1.75 x 2-2.5-3..so looking for supplier to offer 1 master "kit " and then 50/100 ea pcs. Watched some vids said china kits are cheapest buna n (dont like NE low use) and $380/ea from stealer are overkill for 40/h wk Quote
New Englander Posted May 24 Posted May 24 The cylinder I made the spanner for was 6". Gland nut was flush thus the need for a pin spanner. Seals were not simple O rings and piston had wear bands too. It took a 1" impact wrench to get the nut off the piston. It laughed at my 1/2", a 3/4" wouldn't budge it. Bucket truck gave me the sinking feeling😁. One of the outriggers on that truck started leaking badly, so badly I finally put the foot in a cutoff end of a plastic 55 gallon drum to finish the job. Getting the cylinder out of the truck required cutting an access hole and a lot of bad words. I was so tired of it that I just brought the whole cylinder to the hydraulic shop where it cost me nearly 300 bucks to ransom it. The lift cylinder on my backhoe is bypassing but I don't use it much and don't anticipate using except for a small job where it'll probably work ok. That cylinder is probably O rings as the bucket cylinder was and a simple reseal. Bull work and I'm getting too old for that. Quote
acem Posted May 24 Posted May 24 I get most of mine local at RGA and other industrial sources but there are many places to get o rings on the interweb. Here's a good online source for various types including N Buna, Mil Spec, FDA, pharmaceutical, square rings, quad rings, backup rings, etc https://www.theoringstore.com/store/ They are not expensive if you purchase in quantity. You can also make custom o rings with a kit. Can be handy for quick fixes. Ideally you look up the o ring size in the parts books, IH was great for that. Otherwise use the cone of knowledge as a guide. Sometimes they seem to swell or otherwise change. Quote
