73 SL ordering motor mounts for the car to put on next week, some adds show a left and right mount but the photos they look like they are identical. Is there a left and right. I am going with the Meyle brand are the OK, much cheaper than MB.

Always go by part numbers. Photos are usually "stock", and could be for a mount that fits a Ford or Chevy!

The EPC shows different part numbers for left and right. 107 241 10 13 right. 107 241 11 13 left.

I just bought new motor mounts for my 300D. I chose REIN mounts. Original supplier at about $20 each had no stock, so I bought from ROCK. They were under US$4.00!

When I got them, I noticed part of manufacturer's info had been sanded off. But looking carefully, I found a Mercedes Star and the Mercedes part number still visible. There was also another logo and part number. Those showed the mounts were made by Phoenix. Apparently they are a large German rubber company that MB used. They make mounts that are sold under various brand names, including Lemfoerder.

Rein seem to be a reboxer, but are now owned by CRP (Continental et al) - Can only assume they are disposing of old stock this way as various firms merge or are sold.

Well there seems to be variations of engine mounts, for the 350, 450 and 560 are they really all different?

If you post your engine number or VIN (assuming original engine) one of us may be able to check exactly which ones you need. Unless you already have EPC?

All my info, it was more of a question of do all the 107,s have different mounts?

IIRC when I checked the EPC the early 350 and 450s were the same and later 350s and 450s were the same. It showed the chassis numbers when they changed. I didn't check 380s or other V/8s. I didn't check I/6s either.

Those are the right numbers for VINs up to 21761. But I read them the other way round 10 - left, 11 right. But then I could be wrong :) It doesn't really matter - He would need one of each!

Well I am getting them from Pelican Parts, a L & R, I think I will get one cheap-o from eBay to compare.

So got the parts and the two motor mounts, also a third from eBay. The two Mercedes have the different part numbers but look the same to me. Maybe different hardness in the rubber, also the eBay one has a different mating surface than the OEM ones.
Here are the three and the car with the engine support from Summit, got the 19mm bolts out of the mounts with all my ratchet extensions. The four sub frame mounts are loose, so in the mourning will drop the subframe!

So subframe is out! Pulled the U/L A arms to put on the refurbished subframe. The two motor mounts were both #11’s on the car, I can’t tell if they are original, look to be in fare shape. I have drilled out the upper arm ball joint rivets, will press out the lower ball joints tomorrow. The Uro Parts Kit has this for the four subframe mounts, just like what was in the car, but also four of these yellow plastic pieces, in the photo I show two. Do I use these?

Are you replacing with an upgraded subframe? If not, this is the perfect time to reinforce the rear LCA mounts with gussets, if it hasn’t already been done.

Yes, I got a subframe from eBay that had the reinforcement done, then I had it powder coated.

Yes I got the fixit bug, my friend was here and pointed out the starter will never be easer to replace so I just ordered a reman. Now I am thinking about going after that front main seal!

OK, main front seal is out! Removed the upper water hose, fan and shroud then got the belts off. Put a sheet of plastic up against the radiator. Marked the pully with the timing probe. Cleaned the probe and painted red, then removed the six 13mm bolts and the big pulley comes out. Got the bolt off with an air impact wrench, was able to jiggle off the balancer and painted a white stripe at “0” degree marker. Used a puller to remove the fitting and got the seal out with a hook. Will replace the seal tomorrow night.
Should I use a sealer on the outside seal!

So the new seal is in and I noted the power steering pump was also leaking, the 73 has the early Vickers pump, had to look around to find one. The shop said they are getting hard to find. C & M Hydraulics in N. Las Vegas they were really insistent on getting a core back, so I pulled the original today and the pump sits in a cradle that attaches to the engine! Kenny shows on one of his videos how to get the pulley off with a hammer, that did work. Also rented a steam pressure washer today and really cleaned up the front of the engine and under the car, still a lot of crud but much better.
