yarnall Posted March 11, 2011 Share Posted March 11, 2011 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 YarnallA 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).

fxfymn Posted March 11, 2011 Share Posted March 11, 2011 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.

Joe Ditchkus Posted March 12, 2011 Share Posted March 12, 2011 Mike Did you find a source for parts for the Lanova? What size is it? I have a END 510 Diesel in a Mack A-51 T. I have been looking for parts for years not much out there i have found. Thanks Joe D.

steve s. Posted March 14, 2011 Share Posted March 14, 2011 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.
