  • New Issue; need advice on how to address
  • I got both running boards off. I found an issue in the process. On both sides where the rear running board bracket mounts to the inspection plate and the PTO lever; the bolts were buggered; very loose. I had noticed fluid seeping out at the inspection plate and now I know why. One of the bolts at the PTO lever had ATV applied; I guess to help seal it. I have no history of this; I have no knowledge of the running boards being removed the last time the hydraulics were worked on. This is a work tractor, it has never been restored; just repair work; engine overhauled, etc. It needs some care and I am trying to address the issues as I can.

    The question now is how can it be repaired so that the bolts do the proper fastening job?

    I hope all my questions is not a nuisance.

  • Thread repair inserts - lots of styles to choose from. This is low strength application and easy to fix. If you have room for them I like the standard thread ones over teh helical inserts that require a special tap and installation tool. McMaster is your friend:

  • OK, thanks. How do I order? Do I look in the parts catalog for the bolt size and then order an insert for that size bolt? Looking at the page for inserts I am confused at what to get; can you help on which ones I need? These are the holes at the inspection cover and PTO lever.

  • Helical thread repair inserts are ordered by the thread size. They are basically a double sided coiled thread of the size and pitch being repaired - e.g. a spring with coils in a double sided thread form. A spacial tap is used to re-thread the damaged hole just large enough to screw the OD of the helically coiled thread in and the other side magically forms the repaired threads. This requires almost no removal of material from the damaged female part making it ideal for use in close quarters.

    The thin wall, thick wall, and extra thick wall inserts are solid but hollow steel with a standard female thread on the inside and larger standard thread on the outside. Nothing more than a hollow plug with threaded ID and OD. They are also available with a number of different locking mechanisms for keeping them in place. The down side for them is they require drilling a much larger hole for installation. For your application these are the least expensive and easiest to use and a thin wall insert with adhesive for insert retention should work fine:

    3/8-16 x 1/2-13 steel thread locking insert

    You will have to drill and tap the damaged holes for the outer thread - requires a 29/64 tap drill and 1/2-13 tap. Then simply screw the insert into the hole flush with the top (big screw driver will work) and allow the adhesive to cure before installing the cover bolts.

    McMaster is quick and will ship your order UPS the same day you order. I am close to the NJ warehouse and I get my orders around noon the following day.

  • Thanks TOH, much appreciated. And I will be sure to check the thread size.

  • PS>
  • I chose the insert based on the assumption all of the damaged holes are 3/8-16. You should double check me on that before ordering. Pick the insert that matches the thread on the bolts.
