farmer52 Posted 12 hours ago Share Posted 12 hours ago The dipstick guide tube is rusty and broke at the outer support. The guide PN is 715GB530M and NLA from Mack and no dealers show any stock. Seeking a decent guide. Send me an email at mhrollhauler612 at outlook dot com if you have one or know of one for sale. I plan to be at Macungie. Thanks!

Geoff Weeks Posted 10 hours ago Share Posted 10 hours ago I don't know what the MH one looks like, but for my cabovers I made a new tube from 1/2" stainless tubing. length is the critical dimension to get right. On mine the bottom end was a compression fitting and the top end was a bell mouth to accept the "stopper" end of the dipstick, it was a separate piece from the tube itself, and was brazed on to the tube, I heated, removed from the old tube and brazed to the new. Stainless tube is hard to bend, you could use plain steel tube, which is easier to bend. Trick to bend tubeing: make the tube longer than it needs to be by an inch or more. flare both ends with a flaring tool, after installing(temporary) flare nuts. cap off one end and fill the tube full of "sugar sand" tapping several times to make sure it is well packed, then install the other cap. With the tube packed with sand, ends capped off, bends can be made without kinking it. If you try and make too tight a bend you can still split it, but most bends can be made easily. When bent to fit, cut to length blow and wash any sand residue out of the tube, and braze on the bellmouth! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75629-dipstick-guide-tube-for-mh-e7/#findComment-577094 Share on other sites More sharing options...

farmer52 Posted 5 hours ago Author Share Posted 5 hours ago Geoff, Thanks for the information. I am not a fabricator but it sounds easy. The MH guide is similar to one you pictured. I do not know anyone local that can make the part. I requested a print from the Mack Museum and then I will search for a fabricator. Thanks again!

Geoff Weeks Posted 5 hours ago Share Posted 5 hours ago Ken, I wouldn't say it was easy (esp in stainless steel) but is doable by someone who can flare and braze. If you have your old one to use as a pattern, you'll not need a drawing.

farmer52 Posted 5 hours ago Author Share Posted 5 hours ago I will not be able to remove it to use as a pattern since I will be driving the MH to shows this summer. If by winter I still do not have one, I can remove it then.
