v1902 rering or replace

Welcome to the forum from Alabama. I can't help on that but someone will shortly.

I picked up a Scat Trak 1300HD with a V1902 that smokes bad & has no power. The previous owner had the head gone through - new valves, springs, seats..

Compression test
#1 = 390psi, 500psi w/40wt
#2 = 320psi, 400psi w/40wt
#3 = 290psi, 390psi w/40wt
#4 = 320psi, 400psi w/40wt

I talks to the guy that rebuild the head and there are no cross hash marks anymore. He was not paid to measure the bore so he did not.

Should I pull the engine, hone & re-ring or just replace with a good used v2203 from e-bay $1500?

From a purely economic and time standpoint that used motor sounds real good, for that price, but I'd want to hear it run...

I'm not really sure that a V2203 will be a direct replacement for a V1902?
It possible that you might need to rework the bell housing , flywheel, motor mounts and maybe radiator to make it fit.

There is a guy on ebay that will take your old motor replace it with a 2203 for around 1500$ plus shipping. You first must send him your motor so he can mod to all of the things N. I. Wolfman was talking about.

When I get my 743 sealed up on the transmission/hydraulic end I'm pulling my 1702 and upgrading.

I will be the devils advocate here. I had a VW rabbit with 180k miles on it. I bought new rings and bearings, both crank and rod, cut the rim out of the block to remove the pistons, honed it with a simple Craftsman 3 hone and re-assembled. Man that thing ran like a crazy horse, didn't use any oil and I sold it 110K later. I did have the head gone through when it was apart and a friend had the tools to to re-time the injection.

My point is that if you have the skills to re-ring and put new in new bearings I think you would be surprised how long this thing can last.

I simply wanted to upgrade an alternator on one of my machines and that took more work and fabrication than it was worth. I wouldn't want to think of something as major as a engine upgrade. These machines are not like replacing a small block chevy with a bigger small block chevy.

My .02, no offense to anyone here.

Happy trails my friend.

With all of the "new" EPA laws coming into effect...I'd suggest rebuilding it as opposed to replacing it
