MST M542 Parts Catalog – Factory Backhoe Loader Parts

If you’re ordering parts for an MST M542 backhoe loader turbo system and you’re guessing which banjo bolt fits the feed pipe, you’re wasting money and risking an oil leak. Don’t. This factory **MST M542 Parts Catalog** gives you the exploded diagrams, OEM part numbers, and exact quantities – 34 pages of what you actually need to get the right hardware the first time.

Turbo Feed Pipe Assembly: Spare Part Codes and Quantities

This catalog opens with the turbo oil feed pipe. On page 2 you get a clean exploded view: turbo feed pipe kit (4128A028), washers (2131A506), and banjo bolts (3218R036). Each position lists the quantity – for example, position 7 shows four washers, not three. One washer too few and you’ll starve the turbo. One extra and you’re chasing a phantom leak. The manual is bilingual Turkish/English, so the descriptions are clear: “PUL – WASHER”, “BANJO CIVATA – BANJO BOLT”.

34 Pages of OEM Exploded Diagrams

Every page in this catalog follows the same format: part code, reference code, description, quantity, and notes. No vague cross‑references. The booklet is compact – 34 pages – but it covers the turbo system, engine oil lines, and associated plumbing. For a backhoe that sees heavy digging duty, having the right part numbers on hand means less downtime. You can order from any dealer without calling them to ask “which washer?”

Why Trust Factory Part Numbers?

Aftermarket parts catalogs often combine multiple models into one page, mixing up banjo bolt lengths or washer thicknesses. This is MST’s own print, issue M542‑08‑K01, updated 16.12.2008. The part codes are direct from the manufacturer. Compare with the MST M542 2008 Parts Catalog – Factory Backhoe Loader Parts if you need a different revision, but the part numbers won’t change. For a broader look at turbocharger theory, check out the Internal Combustion Engine article – but for real repair work, stick to the factory numbers.

Turbo Leak-Off Pipes: What the Manual Includes

Page 3 covers the turbo leak‑off pipes. Same format: part code, description, quantity. If you’re replacing the leak‑off line, you’ll see exactly which banjo bolts and seals are needed. No schematics to interpret – just a straight legible diagram with callouts. The catalog does not include repair procedures or torque specs; that’s a separate service manual. But for parts identification, this is your only source.

Get the Right Banjo Bolt and Washer Count

Position 8 on page 2 lists two banjo bolts (3218R036). Many DIYers order one, thinking the feed pipe uses a single bolt, but the factory design requires two at the turbo end. The catalog’s note column flags this. Also note: the washers at positions 3, 4, 6, and 7 are all the same 2131A506 part – but their quantities differ. Re‑using old washers is not recommended; the catalog’s quantity column tells you how many new ones to order. MST M542 Spare Parts Catalog 2008 is identical for these part numbers.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It contains only part numbers, descriptions, and quantities.

What can I find in the turbo feed pipe section?

Page 2 shows an exploded view of the turbo feed pipe kit (4128A028) with each component: the feed pipe itself, four separate washers (2131A506), and three banjo bolts (3218R036). Position numbers 1 through 8 are individually listed with reference codes and quantities. If you need to replace the entire feed pipe kit, the catalog gives you the kit part number. If you only need a banjo bolt or washer, you can order the correct individual part. The leak‑off pipe section on page 3 follows the same layout for the return lines.
