Looking for a service manual for this machine. Anyone have one they would like to sell or tell me where to find one at a price less than what John Deere wants? Where is the hydraulic pickup screen located? The hydraulics chatter about half way up.
Both the backhoe and loader do this. Seems like it is starving for oil? Any help appreciated! Thanks for any help!

Take your pick.You can't guess at this.You will have to put gauges in the pump and troubleshoot the problem.There are many posts in the 'archives' that will help you figure out your hydraulic woes.

When it plugs, the hydraulics will work fine at first, but then when part-way through a function - the front pump runs out of oil and things stop working as they should.
It is at the bottom of the transmission case and goes in sideways. There will be plug you remove, and then pull it out.
You'll need to drain the entire trans to get it out. Often, you'll find it plugged with brake lining material, cylinder packing pieces, etc. I've got a complete Deere 300B backhoe/loader service manual in a PDF file. I'd give it to you except I cannot send files that large from my satellite Internet connection. 300B is very similar to your machine. Tech manual is 68 megabytes and the operators manual is 12 Megabytes. Send me a blank CD with a self-addressed envelope and I'll burn and send you a copy.
By the way, my 300B is serial # 141965T and is a 1972 machine. Has the 152 c.i., three-cylinder diesel. 310A was made 1975 to 1982. Sounds like your's is a 1978 vintage.
Gary Schafer Guest Posted: Sun Sep 26, 2010 3:36 pm Post subject: Re: John Deere 310A Thanks for all the comments! I have sent you an email with my email address. The 310A has a 4 cylinder engine.
I think that the plain 310 has a 3 cylinder engine. I am surprised that the 310B also has a 3 cylinder?
I looked on the John Deere site at their parts manual to try and locate where the pickup screen is located but could not find where it is. Thanks for the help!

Deere made a zillion variations of Dubque-type backhoe loaders. Some with three-banger and some with four. 300, 301, 302, 310, 400, 401, 410, all kinds of As. All pretty much use the same basics for the trans, reverser, hydraulics, rear, etc.
You're looking in the wrong place. For the 310A, Deere shows it their parts under 'F' for 'filter, transmission case.'
Item # 9, Deere part # AR26375. I didn't get any forwarded email - but it seems I never do with this Website. Lots of people say they've sent me email, but I've never gotten any. I'll try your's.
