D905E injector pump governor springs and linkage arms please help!!!

I'm extremely happy to find this thread, and its recent as well (you know how when you google something on forums every thread you find is ancient).

I have been working on a Power Tech generator out of a motor home. It has a Kubota D905E, and much like the OP I am missing pieces. But, its due to my stupidity more than anything. The rack is semi frozen on the IP, and while pushing/pulling the rack pin, I broke the darned "trust lever." Talk about bummed. It broke in two, and I was able to retrieve the parts. It appears the rack was so tight because cylinder #3 on the IP is having something go wrong (the bottom roller is stuck in the up position, not touching the IP cam.

So I was worried I was going to have to CAD this piece up and get it made up someplace, but low and behold...ITS RIGHT HERE! Makes me excited. Now, the only problem I see is that lever (the main part in the part #50 assembly) has those two rivets(?) that the "trust lever" sits behind...and thats the problem. That trust lever sits behind those rivets.

To get the new trust lever in place, those rivets (or whatever you want to call them) can not be there, which has me wondering how you would go about this. The lazy way would be to buy the whole assembly, but I would much rather just buy the trust lever. Perhaps grind the back of them off, and the weld them back on after installing the trust lever? I just dont know...

I dont suppose we cant just pull them out of the lever?

With that said, looks like I will be ordering just that part! Thanks!

So that piece has enough meat to drill two holes big enough to fit over those rivets?

hi guys, I have just done rebuilt injector pump and removed all governor parts and replaced. New thrust levers are now hardened steel and sold ex Japan $65 plus freight plus GST

The thrust lever you are refering to is easier than you expect....take the plate of the outside of the engine housing that the governor shaft pivots on ( 2 10mm bolts ), remove gasket, remove collar then insert a small machine screw into the end of the shaft, slowly pull the shaft out and hold govenor at the same time. Take it nice and slow as there is only 1 washer closet to you on the governor...it may stay on governor...do not pull shaft out all the way only as far as you can lift the governor out. Put in vice carefully

sand the rear side of the 2 rivets flush and then tap them out with a small punch. Put your new thrust lever on, rivets back in and then braze the rear of the rivets...do not weld as this is cast

carefully put everything back to together in the reverse order not forgeting to place the shaft washer back as you slide it all together. Springs back in and job done...simple

Hope this helps you all as any other way is just a nightmare and not good

the other thing is if you have broken the thrust lever you will of most certainly broken the throttle control slide on the injector pump...if you have then these are almost not available from Japan any more and if you can find one you will be paying about $295 plus costs. These need to be sweated out using propane or gas, another pin machined to match the old broken one and the sweated back in...not so hard or scary but damn annoying when all this happens

Good luck guys, as always take the calm, and slow approach it will always pay off in the end

Good afternoon,

We’re working on a 2005 BX 23 with a D905 engine. One of the trust levers is broke. Do we have to remove the injection pump in order to pull the rest of the levers out?
