simple A1 strut replacement question

Oct 11, 2003 6 Replies

I going to install my new Boge pro-gas struts cartridges tomorrow. The instructions say that some manufactures require you to add motor oil to the strut housing prior to inserting the cartridge into the housing. I'm not sure it is for some kind of damping or to prevent noises. I don't see anything in the Bentley about putting oil in the housing. should I add oil and how much.



Thanks Steve


Boge Pro gas suck...don't waste your money

Originally the a1 struts were rebuildable with pistons, rings, seals and so forth. The outer shell was the "cylinder wall". When you took it appart to put in a cartridge you dumped the oil and all those parts out. Then slid in a new self contained insert. I've seen what your talking about mentioned, I think it's to prevent rust inside the shell.

Well, nobody had the correct answer yet. You add a little oil so that the strut insert can get rid of heat better. Otherwise the air gap insulates the strut insert somewhat. You don't need much oil, just put the new insert in and pour a little oil in around it so that the gap is filled about up to the top of the insert. The amount isn't critical, nor is the oil weight, and some is better than none. If you fill it right to the top a little might leak out after spirited driving, so leave a little gap between the top of the oil and the top of the strut housing.

Thanks Wes,

That was the answer that I was looking for. The other reply about Progas struts sucking was a big help. But since the guys at Adirodack recommended them I think I'll take their advice over whoever hughie is

I once "cooked" a set of KYBs in my '81 after a long stretch of gravel road driving (50-100 miles) because they had no oil filler (installed by a shop). With my new Bilsteins, I backfilled them, although since they keep most of the oil in the top of the strut, its not as critical. Also, be sure to check the spacer in the strut bearing:
