Throttle Cable

[Frank Sorbello]

How hard is it to replace the throttle cable on a PT 422? And is there an aftermarket one vs Power Trac?

Thanks

Frank

Looking to replace my throttle cable. Does anyone have a part number or size of the cable?

I replaced it on my 1430 in less than 45 minutes. It was sticking when the temperature dropped below 30, which was a big deal last winter in Wisconsin. I was worried about snaking it through tunnel from the front half to the back half, but it was very simple. There are access panels that are easily removed so I could push it straight through. The toughest part was straightening out the s bend at the engine end so I could attach it to the throttle lever on the engine. I was able to move the dash enough to get at the throttle bolts without disconnecting anything.

Frank,
I'd measure the throttle cable and then try here:

Hi Bill,

Do you happen to know the length of that cable? (Maybe you didn't need to think about it if you ordered from PT.) Thank-you in advance.

My throttle cable 'died' today. Since it is attached at both ends, I presume the cable broke/separated inside the housing/sheathing. (I've never seen this on any machine...!!) It could very well be that, somewhere along the line, after ten years, the sheathing wore out from vibrations/rubbing, and the cable eventually also did so.

I'll find out when I pull it out, which I'll do when I have a replacement in my hands. If I'm not going to buy from PT, I need to know the length...

I'm happy to upgrade the quality, if that can be done.

So, I decided to remove the throttle cable to measure it. That way, I could contemplate a non-PT part...

I started by detaching cable at engine, since it seems the easiest way to remove would be by pulling out from the dash. Once everything was unbolted at the engine, the cable/core was free to be pulled out. I was surprised to find out the cable had broken only 4.5in away from its end...??!! Pretty clean cut; no signs of wear/chaffing/rubbing. A bit surprising/bizarre.

I realized that the cable's routing is longer than it needs to be to reach the engine. Presumably, to avoid engine heat. I thought rerouting cable on a shorter path might give me a temporary solution that might make up the 4.5in that was lost.

I removed 4.5in of sheathing and rerouted the cable; it worked. However, the cable now runs below the oil pan, where it will be exposed to a lot more heat... Time will tell...

I'll still inquire from PT about the cost for a replacement. I also thought of replacing and relocating throttle with a much shorter length that does not run through tunnel. As long as one hand can easily reach a lever from the tractor's seat, the lever does not need to be in the dash... Anyone MacGiver'ed something like that...?

Congratulations on getting it working.

Universal throttle cables are pretty easy to find and pretty cheap, if the PT turns out to be an issue.

I wouldn't reroute the throttle cable, but that is me. I think anywhere that is not routed through the tunnel is likely to be awkward, and hard to use quickly in case of an emergency.

All the best,

Peter
