Valves For Mack Lanova


Recommended Posts

I am having a Mack Lanova Diesel rebuilt from a 1950 LFT. The heads are cracked and I have a second set of heads, but they are different angles and I do not have enough good valves for either set. Does any one have a source for valves? They have the 45 degree seat. Parts numbers 690GC291 inlet and 688GC2180 exhaust. I tried John Chalmers, but did not get an answer. Watts does not have them. Mechanic has found them at $85 each. I need eight so $680 plus shipping. Maybe I should just buck up and buy them. Sorry guys, I bought the truck apart so I do not have any good pictures.

Thanks,

Michael Yarnall

A decent automotive machine shop can make generic valves fit your engine. I've had them made in the past. I don't know as to cost but really wasn't cost prohibitive 10 years ago for an old Chrysler inline six cylinder, (218 cubic inch).

Where have you looked so far? I assume you searched the Buda and Allis-Chalmers suppliers that are out there?

Have you tried the ATHS web site yet. There are several A-C owners there that may be able to help you out.

Money, sex, and fire; everybody thinks everyone else is getting more than they are!

Michael, I have had good luck finding odd parts on ebay. If you know the dimensions of the valves you need you may be able to do some cross referencing and find a match either on ebay or elsewhere. Are your valves different than a 673 ? the block is pretty much the same isn't it ? You could also change your valve seats to match the valves you have, if you ended up with a different seat angle on each head, you'd never know the difference. Good luck, Steve

Rev Racing can make any valve that you need. Give them a call.
