Hi all
I just purchased a new Beta 38 for installation into a Valiant Esprit 37. So far the install is progressing well. Turkish dealer, shipped direct from the UK to Turkey.
Questions:
I opted to purchase the standard APV instrument panel.Tach only, No gauges. I want to reuse my existing gauges. The Water temp sender location is easy to fit but the 2nd Oil Pressure port is not as obvious.
Any suggestions.
: Are all of the pipe fittings on this engine NPT type, Beta components and Kubota base engine.
Thanks for the help
Tom
Congratulations on your purchase. This engine works extremely well in the 37 and you will enjoy the smooth and quiet power. You have a bit more work cut out for you with the gauges and senders. The threads are not NPT. The oil and temp sender threads are BSP (also known as JSP) and these threads are standards in Europe and Asia. There is no second oil pressure port so you will have to use a T piece and make sure that it is properly grounded to the engine. You should be able to find a hose from a grease gun with the correct threads that will work for connecting the T piece to the block.
Hi again.. Hope everyone has a good Holiday.
My next question has to do with the fittings for the hot water heater / calorifier.
I see the fitting under the heat exchanger, above the starter. But in the location, as noted in the Operators Manual, air intake side, I only find a very small 1/8 BSP plug??
Help.
Thanks Tom
The 1/8" fitting is correct. Beta Marine has special fittings to make use of this and the resulting system actually works extremely well. Just make sure that you have a fair lead from the fittings on the engine to the hot water heater. The heater needs to be at or below the level of the fill point of the engine so that you dont get any air locks in the system. Below are some instructions that we supply with the fittings when they are sold loose after someone has done their installation.

Addition of hot water heater connections to Super 5 & Super 3 series
Heat exchanger cooled engine
Hot Water to Heater
1.Remove 1/8 plug from side of cylinder head (use 5mm allen wrench on 05 series).
2.Fit 1/8 x ¼ BSP adaptor and then fit ¼ x 5/8 hose connector in position illustrated below last injector at rear starboard side of engine.
Cool Water from Hot Water Tank
1.Remove bung from underside of heat exchanger tank with 8mm hex key.
2.Fit 3/8 BSP male x female elbow.
3.Fit unrestricted 3/8 BSP x 5/8 hose connector.
Note:All fittings to be sealed with Teflon tape or pipe sealant to prevent water leaks when engine is at operating temperature and pressure.
Hi Ok so we are all go here. Engine purring away in the background...
Question what should the oil pressure be running at? With engine warm, it is showing 20-22 psi at fast idle and 40-42 at 2000 rpms, does not change much at higher revs. . This a new VDO gauge and sender. Seems low to me but???
Thanks Tom
The official spec from the Kubota workshop manual is as follows:
at idle speed -- 9.9 PSI
at rated speed -- 28.5 to 63.9 PSI with an allowable limit of 21.3 PSI.
I have never seen an oil pressure problem on one of these engines when new. I think that your new gauge and sender are not matched to each other. Use a mechanical gauge to varify your readings.
Hi
I am using Shell Rimula R3 X 15-40 oil.
I setup a Mechanical gauge and got 28 psi. at idle and 52 psi at speed.
I double checked the VDO sender and it is correct but I did find a grounding issue with the sender. The VDO is now reading 35 and 47 psi min /max.
I really appreciate your help Tom
My setup is Beta 38, Paragon P20 Transmission and Walter Vee drive. Engine mounts are as supplied by Beta, 140 centers and 45 shore.
With the engine in forward and tied to the dock. As I increase RPMs the whole engine / trans is lifting at the coupling/Vee end by about + 1/4 inch. The front the engine is not lifting. I can watch the shaft actuate in/out with changes in load.
My concern is shaft alignment.
BETA UK is saying they have used these mounts sucessfully on other VEE drive setups but they are not sure if it was a short compact ZF vee dr. at 15 deg vee angle or my longer 24 deg setup.
I did get a new mount recommendation from R&D. That they say will correct the problem.
