John Deere Roosa Master injection pump rebuild at home. Did I screw it up? 350C dozer

Be sure to come back for part 2 where we get this old 350C running.

I thought rebuilding mine was coming shortly. I bought my 78 410 backhoe to clear part of my forest to build a pole barn. Day after I was done she would crank but not start. After a few months pulled the tank full of junk. Then had to weld up the pinhole leaks in the tank. So found the transfer pump was bad first. Then the starter went tits up. No fuel to the injectors ended up being the 12v fuel cut off solenoid. Barely audible when keyed on. She runs like a champ again! Oh the roosamaster was super clean inside, was happy to see that. Dig the channel! I will end up buying a jd350 or 450 for clearing around my lake and property. Brian in Oregon

Good luck! These old machines are great but only if you don’t mind repairing often (sounds like your on a great path)

[@trickstothetrades1801]

I borrowed the tools to install the umbrella seals and ended up just installing them like you did. Also the tool to compress the ring when installing the pump was only partially helpful. So no need to wish that you had them

[@anthonyshaw7251]

Nice job👌🙏 impressed at what you do etc, that was a weird way to measure the depth of the bush to 50 thou, the other end comes out of the vernier, if you put that end on the case & the main body of the rear of the vernier on the bush, close the vernier until it touches the bush that is the depth of the bush sticking out, looks weird when writing it out, hope you understand. 👍

[@spankranchgarage]

Thanks 👍 I use that end a lot. The top is just as good a surface but because it’s wider I can rest it on the bushing so I know it’s square

[@stew6338]

Well done, some other KZbinrs have had lots of issues dismantling these pumps. With that said though your pump was in much better condition than their pump was.

[@spankranchgarage]

Thanks. Some of these models have a vent wire that can tear up the case if disassembled in the wrong order. Thankfully this pump didn’t have that design but I did learn that watching other guys try

[@brandonscarfe8803]

Can’t wait to watch this one afterwork! Thanks for the content!

[@Tubroos_Bz]

That's on my list of things to do one day...

[@tectalabyss]

So where is a good place to buy parts from, for these pumps ? Thank you for showing this. Liked and shared.

[@trickstothetrades1801]

I hate that bottom nut on that pump, very hard to start the nut back on and get to even with the specially wrench for it that I borrowed

[@ProjectTrailerz]

You’re spitting out fairly accurate information

[@spankranchgarage]

I try. I’m sure some is wrong but I’m learning every time

[@ProjectTrailerz]

Ya you’re doing fine, post some videos of the buggy haven’t seen it in a while.

[@spankranchgarage]

Im glad you remember the buggy. I have 1 or 2 more things to wrap up in the shop then ill be hitting the buggy HARD this winter. Not riding it for a year has me very motivated to make it great.

[@JamesColeman1]

Nice work

[@resto_roller]

Just a tip on those umbrella seals, if you don’t have the proper tool you can use a small cable tie to compress the first seal.

[@spankranchgarage]

Great tip I’ll try that next time. Thanks

[@jamesblanke9175]

A quick note ,if you cant wait for the rubber ring for the cage and dont want to spend 100 .00 for a newer style, just align them where they need to be and tack weld them together and you have the newer style .The rings are hard to get on but can be heated in hot water. As for the brass bushing you can use a small brake hone and that should take out the wear spots that are ruining the cup seals ,the new seals should have no problem keeping the fuel from entering the engine oil , vasaline helps when installing them also. My question with mine a 2010 is where is the old ring gone. Im thinking towards the injectors or they liquified . I shall soon find out. It did run fine but the shaft seals and brass bushing was worn allowing fuel into the oil.

[@spankranchgarage]

I considered welding. This machine is getting sold to a customer so I wanted to use new stuff. But on my own machine I would try tacking it. The ring disintegrates into the case/return side of the pump. It won’t go into the injectors as that circuit is fed direct from the vane pump. If yours has the glass check ball removed, it’s all likely in the fuel tank by now. No big deal the filter will catch it on the next time round. Mine was clogging the check ball every few minutes but ran with it removed.

[@JeffWahl-m2c]

I was just watching your video and I was wondering where you got that cam wrench from thank you

[@kielbasakevin]

42 minutes of spank, sign me up

[@ProjectTrailerz]

I’m ready for more updates on that buggy, is it still having CV shaft issues

[@spankranchgarage]

I cant wait to start working on the buggy again. Should be just a few more weeks until it gets in the shop for a total makeover. I have a lot of changes I want to make to fix the CV geometry, increase suspension travel, and even add more power and comfort. I am really excited to get back to it

[@bdcharles-dk7rd]

Area diesel service is good shop !!!!!!

[@HorsleyLandy88]

Is that the same Area Diesel Service Schmoo?

[@spankranchgarage]

Quite possibly!

[@johnr8476]

Where did you get the Bristol tool replacement from?

[@spankranchgarage]

mgs4u.com its a radio component company called max-gain systems. The wrench is called 0.291" 6-flute spline tool. Heres a link mgs4u.com/product/0-291-6-flute-spline-tools/

[@chrisallen3741]
