    1972 BMW R75/5 - Tool for Push Rod Tube Removal

    Good morning, but in looking outside, perhaps Merry Christmas should be the word!

    I am wanting to remove my push rod tubes from my 1972 BMW R75/5 engine project to replace. They are so caked in from the PO paint and time that I want to replace them with new ones.

    My question is does anyone have the machining dimensions for making a drift tool to remove the tubes.

    I have a copy of the Matra 530a tool which I used on my R69S. On the Cycleworks site:

    https://www.cycleworks.net/index.php...854a5d4f683cd6

    he says that he "believes" it's also for post 1969. I don't really think so. Vech has two entries on his site for pushrod tube drifts indicating there are different diameters and lengths. The /2 one is 16mm while the after 9/75 tool is 18mm.

    I've not been able to find anything about the early /5s. Might be the same as the /2, but I wouldn't count on it.

    Update: Ran across this thread where a member made a drift for his /7, with dimensions...for a /7, though:
