I just took delivery of a DMC 1450. While greasing it, we couldn't find any grease zerks on the front idlers??? I hope they aren't like a car wheel whereas I'd have to take the track apart and pull the wheel hub off to grease it. There is a cap on the hub but I didn't have time yet to see if it screws on or is a friction fit. It it screws on, I'll take it off and install a zerk in it. If it's a friction fit, I'll have to study it a little more, maybe tap in some bolts from the side to keep the cap on. However, if someone knows there's supposed to be zirk there, and how to find it, it will save me some trouble. Thanks.
