Cat 40 Scraper on the Job

Got a couple of questions maybe you can answer......not sale related.

I assume you've been pulling your #40 with a D4D. Questions are whether you have been using a surge tank with the hydraulic unit and what size GPM pump are you using. Thanks and good luck with the sale, looks to be a fine unit.

Hi AJ, I have a cat hydraulic book and a service manual on the 40 and I think they both have that same picture in them. thanks

Thanks for the feedback.
Those are most likely 35 to 37 GPM pumps, depending on model.
If it works ok I guess that's the answer.

There doesn't seem to be any info about #40 to D4D application.
Closest thing I could find is a dozer, tilt, backhoe combination which utilizes a surge tank.

Thanks Old Magnet for more info, what is the smallest to the largest gpm pumps available and are they just marked with a part number or are they stamped as to gpm? I've never noticed a surge tank in any of my D model parts books but I'll go back through them. Also, take a good look at the hitch on my 40, its twice as heavy as my secound machine but it looks like genuine cat. Somewhere in the past someone mentioned an optional heavy hitch, is this true? thanks

Hi Team,
from my OMI for the 44 Hyd. Control, Form No 31677-1, Dated 10-56, this book has a Factory sticker over the printed S/No position with 22D1-up on it. However the specs are for W S/No units.
Scanned is the pump outputs for the respective S/No Control Units.
Also scanned are the notes for the Surge Tank Applications.
Hope this helps.
Cheers,
Eddie B.
