Description
When your Allis Chalmers starts running rough or losing power, worn exhaust valves are often the culprit. These valves take a beating from the constant heat and pressure of combustion, and when they start warping or not seating properly, you’ll notice it right away. Poor compression, backfiring, and that distinctive popping sound through the exhaust are all telltale signs it’s time for new valves.
What You’re Getting
- Precision-machined valve designed specifically for 201 CID and 226 CID 4-cylinder gas engines
- Heat-treated construction that handles the extreme temperatures of exhaust gases
- Proper stem diameter and valve face angle for a tight seal every time
- Direct replacement – no modifications needed to get back to work
Built for Classic Allis Chalmers Work
This exhaust valve fits the reliable 4-cylinder gas engines that powered many classic Allis Chalmers tractors through decades of farm work. These engines were workhorses in their day, powering everything from cultivation and planting to hay making and loader work. Whether you’re restoring a vintage machine or keeping an old faithful running, this valve helps maintain the compression and performance these engines were known for.
Made to Last
Farm engines don’t get babied, and exhaust valves see some of the harshest conditions in the whole motor. This valve is built with materials that can handle the constant heating and cooling cycles, plus the corrosive effects of combustion gases. The precision machining ensures proper valve guide clearance and seat contact for reliable sealing.
Good to Know
You’ll need four of these valves for a complete engine rebuild since each cylinder uses one exhaust valve. While you’re in there, it’s smart to check your valve guides and seats – if they’re worn, even new valves won’t seal properly. A light valve job at the machine shop will ensure everything seats up tight and your engine runs like it should.
