A 611B Filter Question.

L.Fure · Jun 1, 2020

I'll eventually change the fluid in the torque tube in the 611B. I can find a listing for the hydraulic filter, but not the case-o-matic filter. Is the filter used for the hydraulics the same as the case-o-matic filter? I know the original was an end wound filter that can be cleaned and refused, but it could have been replaced with a disposable filter in the past 60 years. I want to get new filters when I buy the oil just in case they have been switched.

The edge wound filter was the original in both housings, the new paper pleat is OK for the com housing but the rear hydraulic housing has a
lump of casting which will accept the paper pleat filter as it has a milled seat for the edge wound, I have taken cartridge filters out of

the rear casting badly deformed as they cannot seat, make sure that the paper pleat can seat fully and if so use it, if the casting are as many I've seen you will surely see the problem.

Thanks. Hopefully my 611B has the original end wound filters. I'll take the filters out before heading to town to the oil and filters.

Found that both filters are the edge wound reusable type. One is in great shape, but the other is kind of rough. I'll use the new pleated filter for the case-o-matic and the other for the hydraulics. I did see the casting do-dad in the hydraulic filter casting. I think it was put there to hold the filter in position while the cap is installed. Can new edge wound filters be found for these tractors?

L,

Check with John Saeli 315 651 2779 about that filter, DonL 507 433 0073 may be able to source it also, they both are up on what is or is not available

Thanks MEL. After giving it some thought, I doubt I'll put enough hours on the tractor to have to deal with these filters again. Unless you have another idea on the subject.

Whatever you decide, the edge wound would definitely have to be used in the back housing and the new style up front if you wished.
