help needed

Hi all,

I bought a servo for my 109 project, the supplier said it came off a 1983 Landy.
It needed the valve for the vacuum hose. The one I bought(britpart # 18G8953L)
is too large for the hole in the servo.
An inquiry to Britpart says yes there were 2 different sizes and the smaller is
no longer being made (#606406). An online search show this number to be a servo rebuild kit.
If I fail to find one can someone measure and tell me what size the hole in
thier servo is, without the seal, please?


Thanks,
gene

Hey Gene:

No luck with those lazy buggers on the mendo list? I'm not sure if I still have a servo in my pile but I'll take a look.

Thanks Daniel,

Not a peep out of those guys! I guess they are too busy with OT threads. ;^)

From your description it sounded like you have a 50 series servo unit. Much better than the SIII servo unit but never imported into the US on a truck so unlikely to be in anyone's spare parts pile. If it is a 50 series servo unit I hope you have an early Defender pedestal to go with it. The Santana version of the type 50 servo will bolt to a Series tower but not the LR version of the type 50.

I didn't replay to your mendo message because the only thing I have in my pile that would fit a LR type 50 servo is a NOS brake tower assembly. I plan to use it in a future type 80 servo upgrade.

I think you can still get type 50 servo rebuild kits. Did you check to see if a new one way valve comes with the kit? There are one way valves available that connect to the hose and not the servo. Most auto parts stores carry blister pack one way valves. You might find a universal one that fits there.

I am curious. Since you have a diesel, where are you getting your vacuum for the servo?

TeriAnn,

I bought a brake tower, servo, m/c, pedal as all one unit. Don't know how to tell a 50 from an 80 (other than the hole). At his point I've contacted Britpart and Craddocks, both tell me the same thing "need a new servo". All my other online searched ended up with zilch. So now I am at either buy a new servo or open the hole on the one I have. For that I need to know to what size.
The 2.5DT motor has the injector pump run off the timing chain, a vacuum pump is located at the old injector/distributor site.

Why not just buy a hose locally?

Red90,

It is not an issue of hose, it is the oneway valve which is inserted into a seal in the face of the servo. In my case the new valve is larger than the hole and the old valve is not available any longer. You can hopefully tell from the pics the size difference of the seals and how the valve won't fit the servo.

Hey Gene:

I didn't see a servo in the pile. I think I remember getting rid of it when I sold the last pedal tower! Have you considered finding a plastic nipple that is the correct size for your servo and then adding a generic one way valve in the line to your vacuum pump? These should be easy to find. Congrats again on getting the rig running! I need to get off my butt and start working on my rig again. I'm closing in on 3 years since I started!

Daniel

Update!

OK, so I found the correct part. It is part # STC493 Valve, non-return in servo HA-WA 90/110. I bought one from Craddocks for $13.36USD. Came with valve and seal.

Thanks to those who helped!
