  1. done two JLG 600's in my day, put new power cords all the way (21 to 40 wireS) thru the booms and put all new ends on both ends(you couldnt buy the cord with ends on anymore) and its not really a bad job long as your patient. elements kills any of these machines, the upper controls always need to be covered with the canvas cover.

  2. I agree.nothin is original anymore and who knows what some one did. Google search for 673 or711 valve seals shows different results to.guess I'm looking for a part number for those oil shield s and the thick square cut seal that goes inside them.seems to me years ago mack sold the whole kit in like a blister pack with the tophat shields and seals?

  3. There must have been a year these came out?63 711 I'm doing heads on has the tophat collarette s to hold a thick probably 1/2 or 3/8 seal.a bunch are broke...1965 711 I took apart for parts has totally different intake valve spring retainers,  with a liner and a common o ring around top of valves?

  4. Anyone have a part number for the tophats that hold the seals? Took.one motor is apart that had no seals......the other had seals in these tophat things but about half are broke. Of course no one you talk to at mack has a clue...

  5. sounds like your better off finding a truck already built. the motor is an easy change as long as you stick with a 237, 250, 285 anything e6. Matt Pfahl is the one to talk to or Kevin All. they have built many and know what fits.  the front axle gets tricky as the U bolts in a B model are a weird spacing. i know some IH and Freightliner axles will fit

  6. on this taboo topic again. workin on a 711, new heads and top end. anyone have a part number for the valve seals on the intakes? one i pulled apart for the heads had NO intake seals, other motor with a good bottom end has 5 out of 6 seals and the last had an O ring someone put on. didnt Mack use to sell a kit with the metal shrouds and washers with the seals with them????

  7. i know none of the Gurus are on here anymore. my end707 has the 20 stud, 237 head gaskets and fire rings. another 711 im working on has the 18 stud heads with the big corner bolts. when they went to the big corner bolts, did  simply ream the hole out in the gasket for the bigger bolts or did Mack actually make a bigger gasket??? and is the 3029-8213C - head gasket - EN707/END(T)673/END711 with 18 studs the newer version with the corner bolts bigger or the older version
    ?? btw Mack is in love with that part number. they want $258.77 a piece for head gaskets
