The Heinz Posted 10 hours ago Share Posted 10 hours ago Aight ya'll, the parts guy is calling for help for once. Customer has the oldest truck I've ever looked up parts for, a 1967 DM607S, and needs a whole clutch. Impact actually brings up a little information believe it or not, but it's impossible to read. Truck has an END673P with a TRQ7220 quardruplex. He told me the disc was 15" diameter, and the lookup confirms with him that it has a 2" x 10 spline. Any ideas? I found similar on PAI, but I'm not confident given they are a smaller diameter than what he is telling me.

I kinda remember them being smaller than 15 though. There was s single disk CL58 too, but I never remember seeing one Quote Link to comment https://www.bigmacktrucks.com/topic/75284-1967-trq7220-clutch/#findComment-571377 Share on other sites More sharing options...
Joseph Cummings Posted 10 hours ago Share Posted 10 hours ago Joe at Hotrod Clutch probably has them or can build you one. I used to deal with them a lot years ago http://hrclutch.com/ Quote Link to comment https://www.bigmacktrucks.com/topic/75284-1967-trq7220-clutch/#findComment-571378 Share on other sites More sharing options...
Freightrain Posted 7 hours ago Share Posted 7 hours ago Single or dual disc? My Triplex was 2" input, so that sounds correct. I don't remember diameter? 14-15"? I had mine rebuilt at DW Clutch in Maryland. Quote Larry 1959 B61 Liv'n Large......................

Joseph Cummings Posted 5 hours ago Share Posted 5 hours ago Oh BTW, there are shims needed to install a new cl50 clutch. You remove shims to compensate for wear. If his is worn out somebody probably took all the shims out already. Make sure he has them Quote Link to comment https://www.bigmacktrucks.com/topic/75284-1967-trq7220-clutch/#findComment-571393 Share on other sites More sharing options...
