While most folks here seem to own the newer tractors, I know there are still some guys that have the older machines out there. I'm posting this here as much for the "technical documentation" aspect as anything - Have to keep me honest!

A friend of mine recently relocated, and gave me his Cub Cadet 2165, it is only a 16hp, but it's in really nice shape with only 400 hrs. I figured it was a huge technological jump from my Onan P218, so why not give it a go?

First thing's first: Out with the old!

I also separated the driveshaft from the shaft adapter on the Onan. I haven't decided if I want to use the 317 shaft on the Vanguard, as I have larger joints and shafting available (same as used on 318, etc).

I pulled the Vanguard out of the Cub, and started to reconfigure it for my Deere. After removing he Cub driveshaft adapter and screen, I installed the new stub shaft adapter (841580):

Next, I started working on the PTO adapter plate. I did most of the drilling with a hand drill, as I've never moved the old drill press from my parents' house out to our place... Talk about positional tolerance.... It's made of 1/2" aluminum that I had a scrap of laying around.

I need to pick up a few bolts tonight on my way home from work, and try to get this bolted up/fitted so that I can make sure I have the engine placement right in the frame.

Just as a teaser, I had to test fit it, sure looks great in there!

More to follow!

Nice work :fing32: Is there something wrong with the Onan? You should have an easy time selling the Onan install kit for the 317 they always go quickly.

Thanks for the interest guys, I'll be sure to update with more info later this week. For now though, I've hit a snag waiting on the muffler and ended up ordering bolts for the PTO adapter since the local hardware store didn't have the 5/16-24 flat head screws I needed.

By the way, that's not canine, it's mud from playing in the garden last weekend when it was almost 60deg! Today was 30deg with 6" of snow... Crazy March weather!

I am very interested in how you plan to modify the drive shaft to fit the stub shaft that you have on the Vanguard. SEW and Jim's includes an adapter for their 318 kits that allows you to use drive shaft without modifications. However, I think the stub shaft is the way to go when you are not using a kit.

It should be pretty simple for a 318 since they use more readily available u-joints. This Neapco yoke will replace the current flange yoke on the 318 and accept a 1" shaft (on the engine).

Here's the 317 shaft with the adapter removed:

The re-power sounds like a good idea. I will be following the thread.

I feel a bit silly with my latest discovery, but it's an important one so here goes...

The Engine actually has the correct mounting pattern for the Ogura PTO clutch, so the adapter that I made is completely unnecessary. What I do need to do is install spacers behind the winding/mounting plate in order to allow proper spacing between the field coil and the rotor. I'll be working on that tonight....

Glad I figured it out before I got much further though...

John U, was there anything wrong with your Onan P218G? I am just curious, was it showing signs of it's age or being worn out?

Nothing wrong with it other than a bit of surging that I didn't want to have to tinker with to figure out. That, and I'm rather tired of the "Onan cologne".

I received some parts to keep me moving along....
Shiny new muffler from SEW!

Assembled the PTO clutch.

Bolted up shiny new muffler..

Worked a while today, but it almost looks like I'm moving backwards...

You will love the Vanguard in the 317 - I cheated and used a SEW kit for my repower, it was like getting a new tractor!

Between the engine and the other upgrades I'm working on, it practically will be a completely different tractor!

Surprisingly, yes! I was expecting regular low-carbon steel with a black coating, but this is a nice touch. It'll give it that "hot rod" look!
