Dear Listers,
The percentage of members making a Contribution to support the Lists this year
is currently behind last year by at this time by roughly 22%. Please take this
opportunity to show your support for the Matronics Lists and Forums!
Please remember that it is *solely* your direct Contributions that keep these Lists

don't want to support the Lists directly, then I might have to add advertisements
to offset the costs of running the Lists. But I don't want to have to do
that. I really like the non-commercial atmosphere here and I think that a lot
of the members appreciate that too.

| Subject: | Maintenance manual numbers |
This note will be posted to the Jabiru USA, the Matronics, and Yahoo engine
forums. I have solid lifter Jabiru 2200 serial number 988.
Below are data I pulled from several Jabiru documents.
1. Minimum oil temperature started at 59 F but was changed to 122 F in 2005
due to oil pump pressure spikes by SERVICE BULLETIN: JSB 004-3. A recommen
ded (for 2200) modification to the pump fixed the problem. However, later m
aintenance manuals all have minimum oil temperature at 59 F.=C2- I guess
Jabiru assumes all pumps are modified.=C2- The 122 F minimum oil temperat
ure is not in any maintenance manual.
2. Head bolt check torque went from 24 ft lb to 20 ft lt (April, 2011) and
back to 24 ft lb (1 October, 2015).=C2- This is of real importance, why t
he change and is 20 ft lb OK for head bolt torque check?
3. Spark plug torque went from 8 ft lb to 12 to 14 ft lb in 1 October, 2015
. Why?
4. EGT changes, not sure what is cause here.

ru Engine Oil Pump/Oil Cooler
Requires oil pump plate port to be smoothed to avoid cavitation at oil temp

is SB is recommended for 2200 but is mandatory for 3300. Without, modificat
ion oil temp must be 122 F before full power.
