Engine Mounts: IPC v. Lord Catalogue Discrepancy for 67F

[Mooney-Shiner]

Hey, guys, just wanted to post for posterity sake about this discrepancy.

I was looking to gather some info about the engine shock mounts replacement. According to our IPC, my 67F takes J-7402-1 (made by Lord Aviation).  But according to Lord's guide, the appropriate P/N is J-9613-12.  I contacted the vendor about this correct P/N and the shelf life of their cushions and this is what I got back:

Hi Yuriy,

 

Thank you for contacting Parker LORD. According to our internal reference guide, we also call out four of the J-9613-12 engine mounting kits for the Mooney M20F 1967 model. Looking at the component part numbers that come in the J-9613-12 kit compared to those included in the J-7402-1 kit, it appears that the Mooney manual made an error. They have the components listed that correspond to the J-9613-12 mounts as our application guide notes, but yet list the J-7402-1 kit number. For verification, I have included the components of the J-9613-12 and J-7402-1 kits below.

J-9613-12 Assembly:

1. J-7763-1 sandwich mount

1. J-9612-8 sandwich mount

1. J-7766-9 spacer

J-7402-1 Assembly:

2. J-7401-1 sandwich mounts

1. J-7588-1 spacer

These mounts do have a shelf life. The recommended shelf life of the J-9613-12 mounts is 5 years from the date of manufacture (cure date printed on the mounts). However, this limit only applies to the time period when the mounts are in their new, unused condition prior to being installed. Once they are installed, on-condition inspections take over and shelf life no longer applies. We do not specify a set in service life for our GA engine mounts for it varies with application, environment, flight patterns etc.

If you need any additional assistance, please let us know.

Thanks,

Emily"

I'm not sure if anyone ran into these issues yet, but I want to give you a heads up.

Let’s see if @Davidv is cruising by... he may know other people that may be interested in these details...

I believe you are not reading this correctly:

J-7402-1 is a Mount assy intended for M20 C and D models.

Our F models take three parts J-6212-8 + J-7766-9 + J7763-1 which, according to Lord is J-9613-12 assy.

Ah, makes sense now. For whatever reason, I thought my IPC was dedicated F Model pub.  But I'm a better man now.
