ISO: M977 HEMTT crane seal kit or TM for crane

[bigmike]

I’ve been searching for the TM which covers the M977 crane. No luck. There is a seal kit on E-bay but I don’t know which crane it is for. If anyone has the seal kit and/or the TM for the M977 crane, I’m interested.

Have you looked at or searched for TM 9-2320-279-20-3? There are a lot of references to the crane and some of it's parts in that. If you are not familiar with the military TM numbering system, this is the third of many 20 level manuals published, so if it's not here, it may be in one of the others or even in a 30 level manual. And the correct number for a seal kit would be on the -P series.

There are at least two cranes for the M997. Grove and HIAB.

I have never seen any other than the Grove MHC on the M977. And in that TM it is the only one covered.

There is a seal kit on E-bay but I don’t know which crane it is for.

I'm sure you are referring to this kit...
If you zoom over the package it shows a part number: 9-752-100507
And that part number is the seal kit for each one of the two crane lift cylinders on the M977 (code H01 and H06)
Find that number - as well as all the various components of that kit - in Fig. 329 of that parts TM (link in post #3).

In the early 80's, when PATRIOT came out, we were given the M997 with the HIAB crane. It was decided that for some reason I never heard, that the Grove was not "good enough" for transporting and moving the PATRIOT missile rounds from the ground to truck, truck to truck, truck to Launcher and so on. Later, maybe 1987(?) the PATRIOT Project Office had decided to go back to the Grove crane, due to the leakage problems of the HIAB crane. We also had lots of problems getting HIAB repair parts and the TM for the HIAB, (a completely separate TM) was very much sub par. But indeed, for a while, there were two cranes.

There were some m939s with Hiab cranes out on the Arizona GSA last year

Perfect. That’s exactly what I was looking for.

Mine has the Grove crane.

I believe the cylinder I have that is leaking is the...don’t laugh...erection cylinder. Seal kit 9-752-100501

 

[gringeltaube]

Well, that's exactly what they do: erect the mast... So I consider it a well-chosen term.

Sadly, there is not one single part in that kit offered that would fit, in your case.

Guided Missile Transporter
The guided missile transporter (GMT),
located normally with the HHB, is a modified
HEMTT M985. It is used for delivery,
recovery, and loading of guided missiles,
using a heavy duty material handling crane
attached at the rear of the vehicle.
The M985 Guided Missile Transporter (GMT) was developed specifically for use with the Patriot system and it can be distinguished easily from other cargo models by its rear-mounted Hiab 8108/2 materials
