I'm in need of a rear main seal retainer for an E6 engine, the style with the rubber lip seal. Thanks in advance for any help.

Hello, I'm looking for the panel that bolts on the front of the flywheel cover (bell housing) on a B model with a 711 or 673 engine. It's about 12" long and covers the large bell housing opening near the rear of the engine oil pan. It attaches with two 3/8" bolts. Thanks in advance for any help.

Thanks guys. I'm still not quite sure what applies to my 711 though. Here's a table for 673's in my Operation and Maintenance manual.... Here's a table in the back of that same manual for 673P's specifically. It seems like there are different numbers for each pump on each engine. It's unbelievable how difficult it is to find anything specific to the mid 60's END711. My pump number has a P8 suffix, but I can't even find a 673 spec for a "P8" pump. Maybe the Mack Museum like was suggested earlier? It looks like they stopped giving this info in the Mack repair manuals, like Steve said above.

Thanks JoJo, the engine and pump info is in my first post, except that it's in a B61. Also, it's an ENDL engine, if that helps. Hopefully it'll be in your books. None of the TS442 repair manuals I have list it, but I don't have the earliest edition.

Thanks for the replies. We must have the same O&M manual, because those 673P specs are the closest ones I can find too. I didn't think that the museum might be able to help, maybe I'll reach out to them.

Would anyone happen to have the rack setting specs for the injection pump on my truck? None of the manuals I have list mine. 1965 711 engine American Bosch APE6BB-90Q-5069B8 Mack 313GC4135AP8 Thanks for any help

Yeah, that's what I was afraid of. I'll plan on having to take them out in pieces. Thanks for the help BTW, it's an END711

I have several leaking threaded block plugs (freeze plugs) that I'd like to replace the o-rings on. Just wondering how big of a headache it typically is to get them out? Are the block threads usually ok? I think I have the right 1/2" drive socket for them, but when I tried to remove one out of a head it won't be re-using, it wouldn't budge. I'm assuming they're right-hand threads. Hopefully I won't have to cut them out or something. Any words of wisdom would be greatly appreciated.

I think what you're looking for is for sale on eBay now. It looks like the one on my 711. Just search Mack B Model Oil Filter Neck 673/711

Thanks for your reply. The ones you referred to are the shorter and more common ones, 616GC116. I'm looking for 616GC156 which are about 1/2" longer. If you have any suggestions on where I could find them, I'd really appreciate it.

I'm in need of a set of 12 fuel injector studs for a 711 engine, the part number is 616GC156. These are longer than the more common ones, I think these are about 2.75" long. They have a longer wrench area than the other type. I'd be interested in new or good used. Thanks for any help.

Thanks for posting the chart. To tell you the truth, I didn't even know if the jacks that Mack provided were hydraulic or mechanical. So it looks like a B61 would have gotten an 8 or 12 ton. The build sheet lists the lug wrenches that came with the truck too, but I can't even find a picture anywhere of what those things looked like.

I was just wondering what style & brand the jacks were that came with the B model trucks? Assuming they originally came with one. Would anyone happen to know?

This reminded me of one day (at least 15 yrs ago) when I was coming home from work through Boyertown, PA. I came around a bend on the main street, and there was a truck that I think was delivering coal to one of the old row houses in town. It was a late 30's or early 40's vintage truck sitting across both lanes, and the truck bed was raised quite a ways up in the air and had a long trough that went down to I guess the basement window. I assume he was delivering coal (maybe it was wood chips?), but it was pretty cool to see that old truck still getting things done. It was probably a pretty common sight back in the day. I don't know why I didn't take a picture, probably just so surprised to see it sitting there.

Thanks for the reply. I've found a partial kit that should work and will help, but I haven't found the top cover gaskets yet. Maybe they're not available anymore.
