    Deere 748GIII engine oil filter

    I have a customer with a 748GIII, 8.1 liter. Last spring he changed engine oil & filter, it sat for a couple of months and a week ago went to move it. He checked the oil before starting and it was fine, started it and let it warm up. He loaded it on a low bed and moved it to the next job...

    JD 290GLC Engine Squeal.

    I work on a 644K that does the same thing, sounds like a turbo about to come apart but it's an exhaust manifold gasket. With everything involved in changing that gasket the owner is content to let it squeal for awhile.

    Hitachi EX75UR-3 Center joint

    I wouldn't worry about the dents in the housing, they are from the balls (#18 in the parts schematic) riding between the post and the housing. Alot of the rebuilders turn down the post and replace the balls with a brass bushing. I have resealed many that looked like this without any issues. When...

    40F JLG High Lift

    Having dealt with the older JLG machines in the past I can say pretty confidently that the manual will not likely cover this. The older JLG manuals left lots to the imagination. If you have not already done so I would move this post to the one that Willie59 referred to, you will get more...

    1994 case 9020 excavator pilot pump

    Not sure if the 94 year is the straight 9020 or the B series but either way it should have a Kawasaki pump and the pilot pump should be very easy to find. Many manufactures used kawasaki, Kobelco, Link Belt, Daewoo/Doosan are just a couple.

    Kobelco K903A

    Feenaughty Equipment in Portland has been a dealer for years, Farmers Equipment in Lynden & Burlington has been a good company to deal with. Years ago I had a customer with an SK03 which is the grey market version of the 903 and I was able to get most parts although if I remember correctly the...

    Water in hydraulic oil

    Water removal filters only remove approx. 1 teaspoon of water per filter and cost around $50.00 each so that isn't really an economical option. Water contaminated oil is a common problem in all hydraulic equipment and there is no known quick solution. Flush, refill operate the machine and...

    Hitachi Ex120-2 slowly armor plating

    Looks good! We've done that for years around here and it works great. Just remember to beef up the frame work that the doors swing on also. Otherwise a good hit will push them in against your pumps.

    Z45 Engine pivots!

    And they gave us enough room so that even an old fat guy can get back there. The engine on a JLG on the other hand swings out but not far enough, you still have to get down on your hands and knees to get back there.

    Hitachi EX300LC-1 Hydraulic Oil Selection (ISO 68 vs ISO 46)

    In 1991 we knew nothing of zinc free oil, use regular 46 and it will function fine. Back then, and even today many used tractor hydraulic oil. It's not recommended but when they have done it for 8-10,000 hours it's also hard to argue that it's bad for the machine.

    Diagnostic tools

    Deere will sell EDL to anyone, unless you happen to have a dealer who has an attitude. I bought one through the ag dealer.

    1987 c7000 body panels

    Those share the same cab as the pickups so maybe look there.

    Hitachi EX120 1E4-01602, what year is it?

    I can't say for sure what year but the 1E4 serial tells me it's an EX120-5 and they were built from 1996 -2005.

    644k Deere hydraulic hose

    So a few weeks later and the fan pump hose off the front of the tank started leaking. Both times the hose fitting was hand tight. This time, rather than jacking up the cab I built a wrench, 3 foot long piece of flatbar with a 1/2" drive ratchet and a crows foot on the end. Snuck it down...
