Replacing starter and ignition coils on PT422

[BobRip]

I am sending a few pictures.
The one of the fuel pump side does not really give you an idea of the advantage of this removal, but by removing the fuel pump I was able to slide the engine and bracket about two inches towards the fuel pump side and then was able to remove the start which is on the other side.

This picture shows the starter motor side of the engine. The starter motor has already been removed. Please note that one ignition coil is visible. Also both front and back hydraulic pumps have been unbolted. It may not be necessary to unbolt the back pump. I have rebolted it with one bolt and will try to finish the job with it installed. Also note that the gas tank and gas tank bracket have been removed.
I am not quite sure how to get to the coil on the fuel pump side of the engine, but I will investigate this further once I have replaced the starter motor side coil and the starter motor.

This is a picture of the gas tank. Pretty boring. Please note that on the left side is a little white valve. I had previously installed this so that I would not have to drain the fuel tank when I removed it. This saved me a little time.

So far I have not had to disconnect any hydraulic lines.

Hey BobRip,

What is the part number of the NAPA filter that you are using for a hydraulic filter.

It's NAPA 1551. NAPA crossed referenced it from the number of the original filter. I have been using it for four years.

I called Jack Gawecki of Robin today. I gave him the model number off of the old starter and the engine model number, spec number, and serial number. I sent him a fax with this info and my address and then called him back. He stated he would send out a starter and two ignition coils today. My hat is off to Robin. The tractor is four years old and they still send me parts free.
Jack stated that I should be running synthetic oil in the engine and transmission to help with cold starting.

I have one of the valve covers off and it looks very clean inside. I will be adjusting the valve clearance while I have it off. Robin recommends this at 500 hours and I am over 400.

Again, thanks Jack for the support. It looks like Power Trac made the right decision in going with Robin.

I thought it might be a good idea to attach a picture of the starter. The left end of the starter goes towards the front of the tractor. You can see the 0.8 KW rating. The new one is 1 KW. This is about 25% more power and probably torque.
The label on mine was coated with dirt and I could not read or see the label until I removed the starter and wiped the dirt off. The label is up and maybe you can see it with a mirror when the cylinder baffel is on. I did not try that.

I got the new starter and ignition coils today. It took about a week. I started the installation of the new coils. It looks like the gap between the coil and the armature is about 0.014 inches. Does anyone know exactly what it should be.
I hate to set it wrong.

I checked my notes. Jack told me .012 to .020 was the spec. That is what I used and they work. Replacing the coils is an interesting project isn't it?

Thanks again. Yes this is tight. I had to remove the battery last night. I have a lot of bolts out right now. I am going to adjust the valve backlash and clean the cooling fins while I have it apart.
