Tinman22 Posted October 16, 2022 Author Share Posted October 16, 2022 What i've got is an e7 that I would like to put in this 85' R . From what i've seen the e7 had a different front mount than the e6 thats in it now. So im looking for a part number maybe or a pic of the correct mount. I have searched every salvage yard and haven't so much as seen an e7 R model. I tried google images but no luck. I heard there is an R show truck with an e7 that lives about 30 miles from hear but haven't seen it yet.

Joey Mack Posted October 16, 2022 Share Posted October 16, 2022 can you post a picture of the front of your E-7? Quote Link to comment https://www.bigmacktrucks.com/topic/70578-r-model-e7/#findComment-512258 Share on other sites More sharing options...
Tinman22 Posted October 16, 2022 Author Share Posted October 16, 2022 (edited) I'll get one tomorrow when I get back to the shop. But it looks like this. The E6 has a plate from right rail across the front cover and bolts to mount that clamps behind the balancer to the cover then angles behind the stearing box to the frame.

JoeH Posted October 17, 2022 Share Posted October 17, 2022 Looks like it bolts right to the front of the block/timing cover. I didn't look real close. 1995 RD688S, e7-350, mechanical.

Joey Mack Posted October 18, 2022 Share Posted October 18, 2022 yes JoeH, it does.. You have to remove the balancer to remove/replace it.. Im still curious as to how much he needs.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70578-r-model-e7/#findComment-512366 Share on other sites More sharing options...
Tinman22 Posted October 19, 2022 Author Share Posted October 19, 2022 (edited) I got that for $60.00. Now a crossmember for an 85' R . I have a 93' RD dump truck frame I'll go measure that.

Tinman22 Posted October 19, 2022 Author Share Posted October 19, 2022 As far as what I need...Well ,The plan is to remove the e6/t2090 and replace it with the e7/2130. The only parts I THINK. im missing is the crossmember and rubber mounts but im sure everyone will agree its probably not.

Joey Mack Posted October 19, 2022 Share Posted October 19, 2022 you'll be fine.. I'm curious about the swap from an E-6 x-mem to one that will hold the E-7? Quote Link to comment https://www.bigmacktrucks.com/topic/70578-r-model-e7/#findComment-513000 Share on other sites More sharing options...
JoeH Posted October 19, 2022 Share Posted October 19, 2022 The frames are virtually unchanged over the years. You should have no problems finding donor parts from a wide range of years that should work with whatever spec your truck is. Mack did a good job reusing cast frame and suspension components for decades. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70578-r-model-e7/#findComment-513001 Share on other sites More sharing options...
Tinman22 Posted January 20, 2023 Author Share Posted January 20, 2023 Well in the engine swap crossmwmber saga i'm at a dead end. 85' crossmember is a piece of plate 9/16th thick by 10" tall with a 45* bend to go behind the stearing box that the nose of the timing cover sits in and a gets clamped in. the 94' donor truck has a stamped steel "u" shaped crossmember with an appliance that bolts to front of the timing cover and sits on the crossmember. Dealer says the vin numbers ive gotten aren't long enough to use "need last 8 at least" Pic is of the 85' from the top pass. side. Any more ideas?

Joey Mack Posted January 20, 2023 Share Posted January 20, 2023 since when does Mack need more than the last '6' of the VIN.. Im sorry I dont have the whole vin to re-post.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70578-r-model-e7/#findComment-523351 Share on other sites More sharing options...
Tinman22 Posted January 20, 2023 Author Share Posted January 20, 2023 Don't know. They always need my last 8 FA011995 sometimes depending on the part they need the whole number? Nontheless I appreciate the effort. I did hear of an r with an e7 at Boeke and sons over in indiana I might be able to get an eye on. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70578-r-model-e7/#findComment-523352 Share on other sites More sharing options...
