Re: 2004 T-180 Floating before applying down pressure. 7/14/2014 6:30:44 AM   (Total replies: 0)

Sounds like a problem with one of the load holding valves in the loader control.  There is a valve in the output port of the control that prevents the load from dropping when you have the bucket raised and go to raise it some more.  With an open center hydraulic system, it takes a split second for the system to react to an incoming load and build pressure, hence without the holding valves, the load will drop a bit before it begins to ...

Item 7 is the boom lift spool, items 11 &12 are the load check valves (load holding vlaves) and the seats.  There are 2 sets shown, the ones on the right are for the bucket tilt, the ones on the ...

If you are just trying to keep dirt and moisture out, I would use a sandwich bag and a rubber band, one set per hose.  Put the bag over the hose and secure it in place with the rubber band.  This will catch any oil drips as well.

If you need something more robust than this, you can buy JIC plugs from a hydraulic shop to screw into the ends of the hoses.

I don't mean to burst your bubble, but in my opinion, trying a different oil is just a band-aid solution.  It might work, but for how long? And what else could get wrecked the process? 

You need to get to the bottom of the issue to fix it right.  10w30 is the right oil for these old machines, so it needs to operate with it.

Can you rent a machine for a couple of days?

I am going to take a shot in the dark and say that you should not be revving your engine much beyond 3000 RPM.  Your VW motor has the capability of going to 5000 RPM, so you definitely need to throttle back.  Over revving the hydraulic system will definitely have negative performance effects, and could cause damage.

Installing a governor (speed regulator) on your VW engine is highly recommended.  If the one off of the old Ford engine is still serviceable, you ...


Mini Bobtach Adapter - Pre-463 to S70/MT-5X Type 7/7/2014 6:36:44 AM   (Total replies: 2)

In my ongoing quest to keep my old 440b as current as possible, I built up another Bobtach adapter.  I have been wanting to do this one for a while, and the stars finally aligned.

We have a local rental shop that rents MT-52 attachments for very reasonable rates, and I have had my eye on the trencher attachment that they have.  I have had some interest from some of my customers in having some trenchs dug, so I did not want anything standing in way from doing ...

Re: BobTach cylinder 7/9/2014 1:22:37 PM   (Total replies: 2)

I don't have all the dimensions handy, but they are a very customised cylinder, not something you can buy off-the-shelf (except at the Bobcat dealer).  If memory serves me correctly, they are a 1.5” bore with a 1” rod. 

I have an old bobtach at home that was power, I will take the extended and retracted pin lengths off of it for you if you wish.

If you are wanting to convert to a power Bobtach, here is a link you may find ...
