Turbo - like for like swaps???

Post by amos » Thu Jan 06, 2011 7:25 pm

A question dear Brethren.....

My thought process was has anyone used a Holset turbo knowing the engine size, max speed and power rating?

I'm not sure about engines fitted, but if we know that the engine fitted to a 1394/1494 is the same (swept volume, rated power and max speed) as that fitted to a 1410, 1412, 1490, 1690 or 1694 (for which we have turbos specified) and the inlet/outlet connections are the same, then we can assume that even though we are not listed as original fit on those tractors, we can safely assume that we can use one of those turbos.

I'm sure we'd all rather use Holset that Schwitzer!

Amos :D

What you tryin to do?

Have you got a turbo off a certain model of Brown and wondering if it will fit your certain model of Brown or what? Specify what you have got and what you need. The engines you mentioned are similar apart from the 16s which are six cylinder engines. :?

I think Amos and I have been in contact before - if I understand him correctly, he requires a replacement turbo for his 1394 or 1494. We know the Holset turbos that were fitted to the engine(s) fitted to the 1410, 1412 and 1490 tractors, but the 1394 and 1494 are not listed. To know if the same turbo can be fitted to the unlisted 13/1494, we need to know the engine specs for all the listed tractors.

From WesBrown's reply, am I correct in understanding the same engine (i.e. swept volume, max speed and max power) was fitted to the 13/1494 and the 1410/12/90 tractors? If so, we can match a turbo for his engine, even though it may not have been fitted, or at least listed in the Holset records.

Many thanks for any info shared.

1410-1412 used schwitzer turbos as far as I know and going by my own,I personally would rather have the schwitzer as it lasts better than holset but others may disagree it personal preference

Turbos

Post by WesBrown » Sat Jan 08, 2011 10:35 pm

I think the 1394 had a 4/55 engine, with around 72hp. 1490 and 1494 used the 4/55T engine with around 83hp. 1410/12 also used the 4/55T engine but had around 91hp. The 1390 used a naturally aspirated 4/55 engine. The turbo on the 1410/12s looked a different (larger diameter) item altogether than that fitted to 90/94 series engines. My uncle had a 1412 and that motor had some stomp!

The schwitzer turbo went on my 1494 about 10 years ago .I couldn't pickup a schwitzer turbo secondhand So i fitted a holset turbo that was on a 1490 and bought a new oil supply pipe for the holset turbo

It has worked perfectly since i fitted it to my 1494.
