bobcotkg Posted April 21, 2009 Share Posted April 21, 2009 I bought a Jake to put on my 237. I tore into it today only to find the disc that sit on top of the exhaust valves won't fit. I measured and found the ring in the center of the disc was too thick to let it sit down in where it belongs. Kind of sucks because it would have been back together before now. So, do they make different discs or am I going to have to change valves. Hopefully I can just buy them or I have a lathe and the knowledge to make my own. Whats my best bet?Bob Quote Link to comment https://www.bigmacktrucks.com/topic/9112-237-jake-question/ Share on other sites More sharing options...
b61fred Posted April 21, 2009 Share Posted April 21, 2009 hi, sounds like you have the big dia. valve stems. I think the valve stems are .435 or .485 dia. measure the dia of the valve stems and see what they are. The tec brake company makes both sizes. I am needing some of the .435 dia "buttons" I have 4 of the larger size. Maybe we could trade or something? Fred Quote 15 gears...no waiting!

I just bought 6 used ones for $25 clams each. I would have definately considered swapping my 6 for your 4 and some cash. Let me get mine all back together and I'll get ahold of you, if your interested.
