79' Ford 1300 4WD

[sasdakota]

So this thread will be an on going project.

I bought a 79' 1300 4WD with a Schwartz 1200 FEL.

It is lacking on power being 0.8L and rated for 16hp. SO I made the only logical decision and bought an RHF4 turbo for it. Data on the tractor and the turbo is almost non-existent on general google searches. My plan is to update this thread as I go with fitment and how I made it all work (or not work)..

If FedEx does not disappoint, turbo should arrive today and I will begin measuring with some photos. If anyone has worked on this injection pump I'd like to speak with you. :thumbsup:

Looking forward to this project.

"The Fred" is a member here. He added a turbo to a non turbo Kubota. As you progress I'm sure he'll chime in.

Welcome to TBN.

ovrszd, Thanks for the welcoming post. I am excited to see the results from this project.

Turbo arrived, I promptly removed the exhaust and went to bolt on my new turbo... No go. We have clearance issues. See attached photos. I have a game plan for moving forward and will update as I gather more pieces to continue mockup. ENJOY


Here is the turbo. The exhaust flange is a perfect match to the head outlet BUT the 1300 hydraulic pump is in the way, see below.


Stock exhaust removed.


Hyd. pump/filter housing interference.


Spacing the turbine housing straight out away from the hyd. All photos following this are taken with turbo spaced out.


Intake filter will be reversed in the bracket to allow inlet to make a direct line to compressor. The stock rubber tubing will be cut up with other tubing to make the charge pipe and boost reference.


Looking down the side of the hood, turbine sticks out every so slightly but with far better clearance than stock muffler.


Flanges are being ordered to fab a custom outlet back into the factory muffler.

Showcattle,

Do you still have your 1100? If so, would you mind snapping some photos of the hydraulic pump and exhaust outlet area of the engine? I am curious how much different it is to the 1300.

You are going to have a fun time with your project just like I did.

Here's a pile of parts I just removed/replaced on my L3940. I installed a turbo and cranked the fuel, went from 39 to 60 hp.

Engine went bad in 400 hours of hard working. Not saying yours will but most of my work is blowing snow at 3000 RPM full tilt, boost was 6.5 pounds no more. Timing was stock 17 BTDC and I checked it twice all 4 cylinders.

I noticed a little uneven running at idle and when I split the machine to replace a bad HST input shaft seal I figured I would check the engine for leakdown and found out 3 of the 4 pistons were damaged.

Turbo is off now just getting the machine back together and until I finish the thing I guess my wife can plow the driveway with a hand shovel after the foot os snow we got this week.

Also 3 of the 4 intake valves didn't seal correctly and the valves were perfect, the seats had moved around or something I am not sure why. I cut the seats and lapped the valves and they seal just fine now.

Regards, Fred


Good luck, be careful not to go crazy with the fuel setting.

Yes we still have it. I'll try to get pics later today

Any heat damage on the pistons?

The Fred, Thanks for taking the time to share that info! I've done quite a bit of diesel tuning (trucks and conversions) so fuel strategy is not lost on me. I read your thread, you went through **** over there.. Doing some crude math I figure you gained 53% output if you made your 60hp target. I am shooting for a bit more modest goal of 25-35% gain. Hopefully it lives, if not I had fun trying. Look forward to talking with you more.

Showcattle, That is great thanks for doing that.

Agvg, I have not completed the conversion to turbo yet so I am not sure I understand your question? Maybe that was geared towards The Fred but this isn't his thread. Try here, https://www.tractorbynet.com/forums/kubota-owning-operating/311706-i-still-hate-my-tractor.html

I invited Fred over here thinking he might have some offerings. Sorry.
