View Full Version : Fitting IIA 88 Tub

I fit the tub on my 88 (on galvy frame) to check on it's fit relative to bulkhead, and hit a snag.

First, the holes for the tub don't match up with the Marsland chassis attachment points. They are outboard of the chassis tabs by a good few inches. Have others run into this? I suppose that's what a drill is for.

Second, are the extra brackets in the second shot below, an additional attachment point for Series III's that aren't found in IIA's or something? There is no attachment point for my tub and they sit too low anyhow.

Thanks.

Those inner brakets are for seat belt anchors.I'm not sure what is happening with those outter attachment points.I'm heading up to the shop now ,I'll look at mine .I'll report back if someone doesn't chime in before.I assume the rears are lined up?

Marsland chassis are set up for the S3 front tab location, not S2A, so, yes, you have to drill new holes. Before you do, get the front of the tub at the proper height for door/tub, and door/bulkhead alignment. Cut some shims with a taper and keep tapping them in till you have a good straight shot from the curve of the bulkhead, door and tub.

Thanks for the info guys. I will definitely take my time before drilling. Sean, are you sure those inner brackets are for seatbelt attachment points? Wish I had pics of my original set up.

As an aside, I gotta say, for the money, the brackets should line up (or this should be sold as a III frame only, not marketed interchangeably as a IIA and III).

I'll survive....somehow. ;)

Well ,as you can see I've been wrong before :D So am I positive no,but a good friend and a person who I think is in the know had me cut and weld them on my IIa frame before I had it galvied so I had an option to add seats with a hard point anchor in the future ,as per later models (?).I took the measurements off a newly purchased galvy frame. From what I understand there is a L shaped braket that attaches to those and then through the seat base. I'm sure I will be set straight if I'm misleading you :D

your probably right. just having a hard time imagining it.

then again, growing up when i did, seat belts were optional. just as likely to be lying on a mattress in the back as buckled in!

Many a camping trip ,four kids bouncing around in the back of a volkswagon van ,cross counrty and back.Seatbelts, they were in the way ,we tucked them down in the seats .Parents would be brought up on child endangerment charges now days with what my folks did :eek:

Jack, did you install the gas tank before putting on the tub? If so did you replace the following?


Foam Seal - Fuel Filler Tube - Genuine Ref: 504233 /
Gasket - Fuel Fill Tube - Genuine
Ref: 504673

I can't remember if they go between the tank and the tub, or on the tank after the tub is mounted. Does anyone know and does it matter if you use them or not?

On mine (no idea if this is correct, the seal went on the tank, then the foam and then the tub over it all.

Classic memories! Sounds like our parents would be sharing adjoining rooms in cellblock 6.

Mountain - I didn't fit the gasket or foam, this is just a dry run b/c of a bulkhead fit issue. But if I remember correctly, the gasket first, then the foam before the tank would be fitted. At least, when I pulled everything before, that stuff remained 'fitted' until I dissassembled the tank, so I'd assume the reverse would be true.

I don't really know the point of that foam, except to reduce the risk of abrasion possibly against higher points in the truck?

I just bought it b/c it's cheap and figured it must have some purpose.

Reminds me of the urban legend of the Russians reverse engineering a F-15 photo montage for their new MIG. They put a tailhook on their MIG because photos showed it on the F-15. But the F-15 was obviously carrier based. The MIG wasn't of course. I guess I'm Russian when it comes to thinking this through.

I sure would like to know what it does .I bought new as well, but forgot to put it on .I'm not pulling the tank again just for that unless someone here has a reason for its importance

F-14 was Carrier based. I think the Russians used the excuse of - "it is for short runways!"

It's a seal. The holes in the tub for the fuel filler are oversized. The seal keeps little creatures, dirt, etc. from getting inside.

Most US fast jets since the century series have had arrestor hooks. Its quite common for air fields operating these jets to have arrestor gear (http://en.wikipedia.org/wiki/Arresting_gear)in place on the runway.

Jeff ,I'm not sure if I'm talking about the same thing.This is a foam piece with a corresponding thin plastic piece that slides over the fill and vent tubes on the tank.Are we talking about the same thing ,cause if so I dont see how it seals out anything.It may be a cushion or something. I know ,I know this thread is worthless with out pics.

Its 12 and 13 I dont see what they seal.Do they keep crude from going up and over the filler tube underneth the hose clamp.

The seal is sandwiched between the tank and the tub, which slightly compresses the foam and forms a seal.

Does it work as well as the door seals, vent seals, windshield top gasket, front and real crank seals, output shaft seals, axle seals and swivel ball seals ? Probably.

I used to build runway arresting systems back in '81. There were several different types, but all had steel cables attached to thick nylon ribbon on reels. As the aircraft tailhook grabbed and pulled the cable, the ribbon unwound off the reel causing it to rotate. As the reel rotated it spun a hydraulic pump that actuated an aircraft type disc brake on the inside of the drum, slowing it down. An electric motor or gas engine would then retract the ribbon and cable. The gas engines used were two cylinder Wisconsin THD or TJDs.

The cables were held off of the runway surface by a series of hard rubber discs, or held below the runway surface in a trough by air operated actuators. When needed the control tower would release air pressure and the actuators would pop the cable above the surface, held in place by a slit rubber block. The tailhook would then just pull the cable out of the blocks.

In all cases some labor was required to rewind the reels or pop the cable back into the slit rubber blocks before the cable was lowered back below the runway surface.

The neatest system was portable, with the retract reels mounted on trailers. The trailers could be bolted in place at pre made locations (all along the autobahn) or could be set down alongside a runway or roadway. A large hydraulic drill would drive large screws into the ground thru holes in the trailer, and PSP runway sections would be burried alongside attached to the trailer by large turnbuckles. The PSP would give a large surface area to resist rolling the trailer over.

We also made the large nets and towers that would lift up to catch the runaways. I had the opportunity to be an installer overseas, but instead left the business for commercial nuclear power.

Very cool Bob. Simple in concept but complex in execution.


Sean - you were right about those tabs. Straight from the source (Marsland) they are indeed to attach the seat belt female ends to the frame. PO incorrectly installed mine on the tub wall and changed the belts out (I believe). That was enough to throw me off.
