Part 7. MF 35 Rebuild. Engine block.

[@nikolanikic3494]

First of all, I want to thank you for your help with the semmering dimensions. I was able to fix the leaking fault on the gimbal switch lever. And if possible one more piece of information. When we look at the correctness of the assembly with a compression test (measurement) with a pressure gauge of the Perkins A 3152 engine in the cylinder, how much pressure in (bar or psi) should it be on the new engine and what are the permissible oscillations. pressure between the cylinders. As well as below what pressure value in the cylinder is the engine considered faulty. Thank you.

It should be around 350 psi when it’s new, and 300 psi is the lowest pressure, and need a rebuild. If it’s a hard starter and there’s a lot of blowby, usually the top piston rings is broken.

@@Mr.MillersWorkshopThank you very much for the information because I did not have that information. If I understand 350 psi cylinder pressure, good engine condition. 300 psi and below is bad. And what brand of parts manufacturer do you advise me to install. Piston, piston rings, liner, valves and crankshaft bearings. Thank you very much and I wish you all the best..

I can’t tell you where to buy parts, because I don’t know where you’re living.

@@Mr.MillersWorkshop I live in Croatia and have no problem looking for parts anywhere in Europe. It is important for me to know which manufacturer the quality is. I have heard of Sparek is good and where is it available except UK and if you can tell me which other manufacturers also have quality I am asking because in our market they only offer IPL India, Jenmack Turkey, SM and NPR, Germany but all bad and questionable origin and quality, so I wouldn't mount them because I just need quality. I build the engine exclusively for myself, not for resale. If you understand me.. Greetings and congratulations, you helped me a lot through clips to overhaul the MF 35 from my grandfather.

If you can get it from sparex it’s good quality.
