RE: Rusty 996, what do do?

Afternoon BAM
I did my bonnet not that long ago. With a good cleaning and light hand sanding and then a rust paint. It did not come out too badly. It is not 100% but as you have said. A good patch until the time is right. At least it will not get worse.

DB 990- Engine issue

Afternoon All Time to get the Db dusted off from the winter.  My 990 has a little oil coming out of the joint between the exhaust manifold connection and the block when I work her very hard. Example hay bailer. How concerned should I be? I have heard that some causes are piston ring cracking. Is th...

Well I split the DB drown again to check the orientation of the clutch plate and all was well. Everything was sitting flat a free moving and yes the dowls are good.

So I put her back together and adjusted the 3 set screws to 0.05â€Â￾ instead of 0.07
I also want to remove the 0.06 slim under the arms I put, because if I advance too much now, I think I will have a problem later in that as the clutch disks wear the arms move up. Right? And I will not have any adjustment left.

So I am thinking if my pedal screw is almost all the way screwed it. It is not too bad since as time goes on I will have to back it off to maintain the gap between the trust bearing and the small pressure plate as my clutch plated wears (Maintain the 2â€Â￾ free play at start of pedal stroke). Is my logic correct?

I really don’t like reducing the 0.07 to 0.05 or 0.04 but I don’t see anything else.
Anyone see something I am missing?

Cheers Don

Ok
I will recheck the clutch plates just to make sure.

DB780 what does “you have dished it on reassemblyâ€Â￾ mean?
Bowing the clutch plate?

Powerrabbit I am fine to check what you recommend. I just did not follow the “ 2 dowelsâ€Â￾ part . I know about the three springs. Does the 990 sel have these dowels? Where about .

Thanks Guys

RE: DB Brown at wits end!!!

Yes I notice the stickers too. The cone end for the pto clutch pointing forward. Goes in the little coned plate I was not sure about the cover that applies pressure to the separate plate though. It looks like it sits directly mid way on the teeth. That would mean to me that the max distance the sepa...

DB Brown at wits end!!!

Good afternoon all

Well I have just about finished the installation of my new clutch in my DB 990 sel. But I am having a real challenge.
The PTO plate will not to disengage under the proper settings.
The tractor is fully open so I can see and adjust everything , but it is just not happening. I have the technical manual and am running out of ideas. So any help would be appreciated.

I have changed for new the following, PTO clutch disk, Main drive clutch disk plate, the full cover plate assembly new front bearing and new snout support.
I have reground the separator plate by .01-.015â€Â￾ to remove some grooves
And the three set screws are set to 0.07â€Â￾

So here is my problem

In order for me to disengage the main and PTO clutch I must adjust the pedal screw almost all the way in. Therefore this is making contact between the PLATE, (release levers) and the thrust bearing. However there should be at least 1/8â€Â￾ gap between right for that 2â€Â￾ free pedal play before the stroke?

So I came to the conclusion that my stroke length of the pedal and the stoke length of the clutch/pedal was out (Clutch more to the front and the trust bearing more to the back) .
So If I increased the slims under the adjusting pad that would lift the release leavers, which would shift my stroke range on the clutch towards the back. Now I would have the full coverage.
I calculated 0.06â€Â￾ increase. (Which I thought was a lot)
Well I did advance it. But still was not enough. ïÂ￾Å’ Again the thrust bearing and , plate(release levers) had to be in contact for me to reach the PTO . Oh and when I am in this setting I get the 1/3 PTO stroke and 2/3 Main Clutch range on the pedal. Which is good.


I am at wits end any ideas? Thanks

Cheers Don

RE: 990 DB Conclusions

Thanks guys I was pushing the clutch all the way. Example snow removal. Drive foward unit your bucket is full and then clutch in full. Then lift. If I only push the clutch for the first stage, I should have real power then. Ivan thanks for your help. I am almost down with the rebuild. Just pulling t...

990 DB Conclusions

Morning All I am in the process of changing my clutch on a 990 DB sel and just realised something when I had it apart and am very interested in what you think of my conclusions. I noticed that I did not have as much power in my hydraulics as I thought I should have, and decided to take a look at the...

RE: PTO - Will not disengage

Well I have good news and bad. I did that test that you recommended (Clutch in full PTO engaged and tried turning the PTO drive) and sure enough the engine turned. ïÂ￾Å’
So I have possibly two sources right? PTO disk warn out or PTO disk stuck to plate right?
I have started to prepare for the split.
Is there any trick or things I should know when splitting her or is it easy? (Remove the bolts and she pulls apart very easily).
I would hate to split her and have spring and parts fly everywhere. I hate when that happens.
I also have the service manual for the 995(I have 990 SEL). They talk about straight edges when reinstalling the clutch for adjustment. How good are these instructions?
I guess I am back to any tricks?

Cheers Don

RE: PTO - Will not disengage

Ouch !!!
Now that will take me a while to change.
Is there any other tests besides pressing the clutch pedal in that will confirm the PTO plate is worn out?
Thanks for the feed back by the way.

PTO - Will not disengage

On the subject of PTO adjustment, do the three set screws affect the disengagement of the PTO slip clutch on the clutch assembly? I have a problem where the PTO will not run free when I put the clutch in. When I push on the clutch pedal I can see a disk moving up to the three set screws that were me...

RE: DB Loader power issue

Thanks Guys I.F - I changed the filter on the left hand of the seat! Is that the filter you are referering to? Is there another screen I missed. As for the rest, I shut off the valve for the rear lifting hydraulics and ensure the valaue is open for the loader. The big level to the right of the seat ...
