Hello all,

 

Been a while since I have trekked over here. Quad bypass and health has had me set back a bit and still not 100% but life goes on.

 

So, I had unfinished motor details on my 1053. Trans went out on the 850. My thought at this point is to move the good S8D over on to the 1053 until I can fix the TRA-10D.

 

So I ask this ... will the pulley from the S8D fit onto the TRA-10D ? Both have the same wiring, ignition switch, etc.

 

Happy winter to all.

I can't remember if the shaft sizes are the same but another thing to consider will be the belt fitment, I don't think the S8D and TRA engines are the same physical size. You may need to adapt custom belts.

Welcome Back!

 

Besides the differences in HP you'll have to swap over the engine pulley's as the S8D is going to have the wrong sheaves on it, the 1050 one used dual drive belts on the Drive and PTO

 

Pulleys will change over no problem

I belive the shaft size is the same,so you may have to use the engine pulley from the other engine,I don't think the belt grooves will line up from the 8 hp pulley

Thanks for all of the replies, guys. Motors have been pulled and pulleys are swapped. The S8D now sits on the 1053 and I will be measuring from the bottom of the motor casing to the center of the crankshaft extension of each to be certain a custom belt fitting is not required.

 

I can't remember if the shaft sizes are the same but another thing to consider will be the belt fitment, I don't think the S8D and TRA engines are the same physical size. You may need to adapt custom belts.

 

Thanks for the tip to check this, chubien.  :thumbs:

The engines will sit the exact same height and take OEM size belts :thumbs:

It sure does. I did learn one thing. Before securing the pulley in place on the crankshaft extension leave it back somewhat and tap it in place to align with the transmission pulleys below. Otherwise, you will be pulling the motor again to pull it out enough to align it (like I did  :wallbanging:  ). 

 

I hope my lesson will save another the time. :smilewink:

I'm happy that the swap over works. Best of luck with your health that comes first.

Well ,went well with the swap. I did end up swapping carbs and intake manifold from the TRA-10D to the S8D. Intake on the blocks are the same bolting pattern.

 

With new belts on, fluids changed or topped off this machine was no match for what Mother Nature just dumped on us. Not with a snowplow.

 

Between my shoveling, my neighbor's snow blower and the owner of Arden Tractor Center (John Deere) using a new Deere with a 48" snow thrower I was finally able to get some ride time to help with some cleanup and give the 1053 a workout.

Now to plan the 10HP rebuild in Spring AND snow thrower resurrection.

How does it run with with the L63 carb? There was another post about someone doing this swap and claims it runs flawless. This being the case I may consider trying it on some of mine as a have a spare L63.

I started with setting the carb like instructed in the repair manual for a TRA-10D motor. One and a half turns out from close for the bottom screw. Can't remember the top screw next to the venturi. Once I got it running and warmed, finalized the adjustments, It ran very well. Had a hiccup at full throttle (surging) but backed off enough until it smoothed out.

I'll wait until Spring, when I can mount the mower deck, to adjust it again when I can put a load on it with the PTO.
