In Reply to: super M hydralic pump on a regular M posted by Paul G. in Mn on April 25, 2004 at 18:45:49:

Paul I have collected parts to do the same conversion on an early
M. Have not done it yet but have searched old archives for info
and advice. The plate between the front cover and block will
need to match (3 holes match and one is about 1/2 hole off so
some posts claimed to drill plate, fill & re-tap cover). I am going
to replace plate, cover, and gears. The pump and cam gear is the
same fit, but the ones that came out with the SM, 400 & 450
were made of stronger material, so there were posts of gears
sometimes breaking with this conversion when gears are not
changed. I found this link to pix of timing gear repair by Bob M
VERY helpful to get me ready to do this job.

The manifold I got with SM pump has one compression fitting
and one line requires a clamp, but manifold has a hump. The
400 that I have seen has the same manifold with short soft lines
between it and the steel lines. One about 4" long with clamps.
The other about a foot long made on the smaller metal line with
a compression end.
Good luck_hope this helps

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th ... [Read Article]
